April 2025

RBS USAR Section 13.3 Emergency Planning 13.3 EMERGENCY PLANNING 13.3.1 Scope and Applicability The following plan has been developed for the River Bend Station (RBS) near St. Francisville, Louisiana, and its environs in accordance with the regulations stipulated in 1 0CFR50.33, 50.34, 50.47, 50.54, 1 0CFR50, Appendix E, 1 0CFR70.32 and 1 0CFR72.32 (c). The plan follows the guidelines established in NUREG-0654/FEMA-REP-1, Revision 1, "Criteria for Preparation and Evaluation of Radiological Emer-gency Response Plans and Preparedness in Support of Nuclear Power Plants," and Supplement 1 to NUREG-0737. The emergency classification initiating conditions and emergency action levels are based on the methodology of NEl-99-01, Methodology for Development of Emergency Action Levels, Rev. 6.

The River Bend Station is situated on approximately 3,300 acres on the east bank of the Mississippi River in West Feliciana Parish, Louisiana (Fig. 13.3-1 ). It is approximately 24 miles (38.6 km) northwest of Baton Rouge, Louisiana. US Highway 61 runs in a northwest-southeast direction, approximately 1 mile (1.6 km) northeast of the reactor. West Feliciana Parish 7 (Powell Station Road/State Highway 965) runs in a north-south direction into the center of the property and passes within 2,700 ft. (825 m) of the reactor. The area within a 10-mile (16.1 km) radius is composed of parts of five parishes: West Feliciana, East Feliciana, East Baton Rouge, West Baton Rouge, and Pointe Coupee (Fig. 13.3-2). There are three population groups within this 10-mile area: St. Francisville (1,712), Jackson (4,130), and New Roads (4,966) (2000 population figures). The area within 50 miles of the site encompasses all or part of 24 parishes or counties in Louisiana and Mississippi. Fig. 13.3-3 shows the population within a 10-mile (16.1 km) radius of RBS. Fig. 13.3-4 shows the population within a 50-mile (80 km) radius of RBS.

The independent spent fuel storage installation (ISFSI) is located within the protected area boundary for interim dry storage of spent fuel. The HOLTEC spent fuel storage casks are designed to ensure pro-tection of public health and safety through the use of physical barriers to guard against the uncontrolled release of radioactivity and through the use of shielding to minimize radiation dose to the public from both normal and off-normal conditions of operation. The analyses summarized in the HOLTEC Cask UFSAR demonstrate that under assumed accident conditions, the consequences of accidents challenging the integrity of the barriers will not exceed limits established in 10 CFR 72.106.

Entergy Operations, Incorporated (EOI) will maintain the Emergency Plan and Emergency Implementing Procedures (EIPs) as two separate documents. While separate copies of this plan are available, this plan is incorporated by reference in the USAR and is subject to established methods for updating. The EIPs contain detailed information extracted from the Emergency Plan and other pertinent documents.

These EIPs allow the station personnel to implement this plan and the proper actions, coincident with normal operating procedures, without referral to numerous documents. A listing of the EIPs is provided in Appendix F.

The objective in emergency planning is to develop a plan and corresponding emergency implement-ing procedures that will ensure emergency preparedness and provide means for mitigating the conse-quences of emergencies, including very low probability events, in order to protect the health and safety of the general public and site personnel.

The plan, as presented herein and the EIPs provide direction for emergency response to emergencies.

These emergencies vary in severity from minor events to situations involving real or potential offsite radiological hazards. Details of the onsite emergency response are contained in this plan and the EIPs.

The interrelationships between the various elements of onsite emergency response and the elements of offsite emergency response are described in this plan, the EIPs, the Louisiana Peacetime Radiological Response Plan and its River Bend Station Attachment and the Mississippi Radiological Emergency Plan.

2. Organization and direction of plant personnel actions to limit the consequences of an accident.

3. Organization and control of RBS activities to assess the extent and significance of any uncontrolled release of radioactive material, notification of offsite authorities as required, and coordination of response activities with offsite support groups.

4. Delineation of protective actions and measures, which are based upon and are consistent with the EALs specified in NEl-99-01, Methodology for Development of Emergency Action Levels, Rev. 6.

13.3.3 Emergency Conditions 13.3.3.1 Classification System The Emergency Plan is based on consideration of conceivable consequences of potential situations, ranging from events where effects on the plant are negligible, to highly unlikely major releases of radioac-tivity which could affect members of the public. Each more severe emergency classification represents an increasing level of actual or potential risk to offsite areas and requires the initiation of predetermined Revision 50 10 April 2025

RBS USAR Section 13.3 Emergency Planning emergency actions by the utility and offsite agencies. The specific designation gives an immediate indi-cation of the severity of the situation when an emergency is declared.

River Bend Station maintains the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of indications to plant operators that an emergency action level has been exceeded and promptly declares the emergency condition as soon as possible following iden-tification of the appropriate emergency classification level.

The emergency classification is initially assigned when plant conditions reach the specified EAL initiating conditions given in Table 13.3-1. When an initiating condition is met, the emergency is classified using the implementing procedure EIP-2-001, Classification of Emergencies. Further analysis of the actual or potential degree of safety degradation may result in reclassification.

There will be prompt notification to the Louisiana Department of Environmental Quality (LDEQ), the Gov-ernor's Office of Homeland Security and Emergency Preparedness (GOHSEP), the Mississippi Emer-gency Management Agency (MEMA), the Mississippi Highway Patrol (MHP), and the five local parishes of any declared emergency status. State and local Emergency Operation Centers (EOCs) will be acti-vated in accordance with the Louisiana Peacetime Radiological Response Plan (LPRRP), its RBS At-tachment, and the Mississippi Radiological Emergency Preparedness Plan (MREPP).

13.3.3.1.1 Unusual Event The Unusual Event emergency classification is declared when events are in process or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs. The off-normal plant conditions could reasonably have the potential to escalate in significance if proper action is not taken or if circumstances beyond the control of the operating staff render the situation more serious. The emergency response may be handled by shift personnel without additional support or activation of emergency response facilities.

13.3.3.1.2 Alert An Alert emergency classification is declared when events are in process or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that in-volves probable life threatening risk to site personnel or damage to site equipment because of intentional malicious dedicated efforts of a hostile act. Any releases are expected to be limited to small fraction of the EPA Protective Action Guideline exposure levels. Although the potential for limited radiological releases in excess of technical specification limits may exist, the initial assessment leading to this classi-fication indicates that it is unlikely that an offsite hazard will be created. Substantial modification of plant operating status is a highly probable corrective action, if it has not already taken place by the automatic protective systems. A limited evacuation of affected station areas may be necessary as well as alert-ing appropriate offsite emergency organizations that assistance may be required, should the situation become more serious. The station will activate all emergency response facilities and the JIC.

13.3.3.1.3 Site Area Emergency A Site Area Emergency classification is declared when events are in process or have occurred which involve actual or likely major failures of plant functions needed for protection of the public or security events that result in intentional damage or malicious acts; (1) toward site personnel or equipment that could lead to the likely failure of or; (2) prevents effective access to equipment needed for the protection of the public. Any releases are not expected to result in exposure levels which exceed EPA Protective Action Guideline exposure levels beyond the site boundary.

In these events, there is a potential for radiological releases that may require the initiation of protec-tive actions, including plant evacuation. If not already accomplished, the station will activate all the emergency response facilities including the JIC. The Emergency Director will provide status updates to offsite authorities. Appropriate offsite authorities will be given radiological and meteorological informa-tion and projected dose estimates based on actual and/or projected releases. RBS will notify the State Revision 50 11 April 2025

RBS USAR Section 13.3 Emergency Planning of Louisiana, the local parishes, and the State of Mississippi in accordance with the Louisiana Peacetime Radiological Response Plan (LPRRP), its River Bend Station Attachment, and the Mississippi Radiologi-cal Emergency Preparedness Plan (MREPP). Upon notification, the states may activate their emergency operation centers and dispatch their key emergency personnel, such as the Louisiana Field Monitoring Teams and the Mississippi Radiological Emergency Response Teams (RERT) to assess offsite conse-quences. The State plans provide guidance to State and local authorities regarding the appropriate responses for the initiation of public protection (i.e., notification of the public to take shelter, evacuate or institute food, water, and milk controls) in the event the Louisiana and Mississippi Protective Action Guides are exceeded. The Site Area Emergency status will be maintained until an escalation in emer-gency class occurs or the status is terminated. Offsite authorities will be informed of the change in the emergency status and the necessary documentation will be completed.

13.3.3.1.4 General Emergency A General Emergency class indicates that events are in process or have occurred which involve actual or imminent substantial core degradation or melting with potential for loss of containment integrity or security events that result in an actual loss of physical control of the facility. Releases can be reasonably expected to exceed EPA Protective Action Guideline exposure levels offsite for more than the immediate site area.

If the following items have not been initiated, they will be instituted during a General Emergency:

1. All emergency response facilities and the JIC will be activated, if not already activated at a lower level emergency classification.

2. The offsite radiological monitoring teams will be dispatched.

3. The Emergency Director will update Federal, State, and local officials periodically on the station status, radiological releases, meteorological information, radiological dose projections, and affected downwind areas.

13.3.3.2 Spectrum of Postulated Accidents This section of the RBS Emergency Plan reflects how the postulated accidents investigated in the USAR are included in one of the four emergency classifications described in Section 13.3.3.1. Table 13.3-1 indicates the appropriate emergency classification which is declared upon reaching an EAL. Table 13.3-2 lists example accidents, the associated emergency classification into which each would likely fall, and the resultant doses at the exclusion area boundary. Table 13.3-3 lists the same accidents and presents the maximum concentrations expected to occur on the applicable radiation monitors.

A complete discussion of any of these accidents may be found in USAR Chapter 15. Methods of de-tecting and evaluating accidents include the use of installed systems, instrumentation, alarms, approved procedures and specialized training. The principal methods are summarized in the following subsections.

13.3.3.2.1 Instrumentation Capability for Detection Abnormal conditions and situations as well as accidents can be detected in a number of ways, some of which are the monitoring of instrumentation, annunciators, and alarm systems by trained operations personnel who can recognize and respond to abnormal and/or emergency situations; the actuation and operation of engineered safety features; the actuation of fire detection and protection systems; and the performance of routine practices, such as sampling and analyzing process systems, performing radiation surveys, and monitoring trends and recording data on significant system parameters.

The plant systems available to identify abnormal radiological conditions include the Process and Effluent Radioactivity Monitoring Systems (discussed in detail in USAR Section 11.5) and the Area Radiation and Airborne Radioactivity Monitoring Instrumentation (discussed in detail in USAR Section 12.3.4). Both of these systems will provide information necessary to initiate the appropriate emergency procedures, as well as continuing accident assessment during an accident. The magnitude of the source term with Revision 50 12 April 2025

RBS USAR Section 13.3 Emergency Planning release potential will be determined based on plant system monitors. EIPs include the methodology for determining the release rate and projected doses.

EOI has the capability to monitor both inplant and offsite iodine, gas and particulate activity.

EOI has the capability to estimate airborne iodine concentrations to less than 10-7 uCi/cc by the offsite monitoring team using equipment provided in the emergency kit.

13.3.3.2.2 Evaluation The Shift Manager is responsible for the initial evaluation of any abnormal or emergency situation, as well as being responsible for the safe and proper operation of the plant. He will make use of all means at his disposal, including instrumentation, equipment, instructions, and personnel, to determine the magnitude of an accident and whether or not a potential hazard to the health and safety of onsite personnel or the public exists.

If it is determined that an emergency condition or situation does exist, the Shift Manager shall assume the responsibilities and authority of the Emergency Director until relieved of those responsibilities by a member of the RBS Emergency Response Organization assigned that duty.

The evaluation of Unusual Event emergencies can usually be accomplished by the normal operating shift under the direction of the Shift Manager. However, for higher level emergencies other members of the RBS staff, including emergency teams, will be called upon as required. Technical services and support will be obtained as necessary from RBS staff personnel.

The emergency response personnel will utilize the detection methods previously described in evaluating the emergency. The equipment necessary for assessment or initiation of safety systems is designed to operate following an accident. (Refer to USAR Chapters 6, 7, 8, and 9 for details associated with such instrumentation and equipment.)

In evaluating an accidental release of radioactive materials, the first item that must be determined is the amount of activity released or, if the release is still in progress, the release rate. Normally this information is provided by installed radiation monitoring systems.

In addition, these systems are routinely sampled and analyzed. Radiation and contamination surveys are performed and air samples are taken as necessary to provide supporting data. If actual data is not immediately available, the magnitude and duration of the release may be estimated by RBS personnel from plant conditions or from knowledge of the type of incident.

An estimate will be made of the radiation dose which affected population groups may potentially receive as a result of an accidental release of radioactive materials to the environment. This projected dose will be determined from the type of release and the amount of dilution when known. All liquid releases offsite will occur through the cooling tower blowdown line or liquid radwaste effluent line, which have radiation monitors associated with the Digital Radiation Monitor System (ORMS) that continuously detect radiation in the blowdown to the Mississippi River. The radiation monitor will alarm via the ORMS operator's console in the control room for any radiation levels above pre-established setpoints.

The setpoints are established to ensure that any planned or unplanned releases from the plant via the liquid pathway are detected if concentrations approach the 1 0CFR20 limit. EIPs direct the use of the methodology described in the Offsite Dose Calculation Manual to determine if the projected dose com-mitment exceeds the EPA Protective Action Guidelines for ingestion. Sampling and analysis of drinking water and industrial water downstream in the Mississippi River can be implemented if radiation monitor levels and onsite investigation determine a potential radiological hazard.

The travel and dispersion of an accidental gaseous release is a unique function of meteorological con-ditions. A meteorological monitoring system provides the data necessary for determining the dispersion factor. This dispersion factor will be used in conjunction with the activity known or estimated to have been released in order to determine the projected dose.

Detection and evaluation of accidental releases that are classified as either a Site Area Emergency or a General Emergency will normally be confirmed by field methods. Such methods will be specified in the Revision 50 13 April 2025

RBS USAR Section 13.3 Emergency Planning EIPs and will usually require the dispatching of emergency teams to obtain and analyze samples and perform surveys. The results will be reported to the Emergency Director.

13.3.3.3 Review of Emergency Action Levels (EAL)

The State of Louisiana and the five local parishes have identified Protective Action Sections within the 10-mile EPZ. The EPA Protective Action Guides, the Protective Action Sections, the EAL Tables, and Evacuation Time Estimates (Appendix D) were utilized in developing the specific Protective Action deci-sion making process. The state and local authorities annually review the EALs in Table 13.3-1 and their interface with RBS with regard to offsite response necessary under the four emergency classifications discussed in Section 13.3.3.

13.3.4 Organizational Control of Emergencies Using the normal operating organization as a base, this section of the plan describes the activation of the emergency organization and the assignment of authority and responsibility for functional areas of the emergency response. The latter part of this section describes the functions of offsite organizations and their emergency roles.

13.3.4.1 Normal Operating Organization The normal operating organization is discussed in Section 13.1.2, Operations Organization, of the USAR.

Table 13.3-17 of this plan indicates the minimum staff available during normal operation to perform emer-gency response functions. An operating shift crew consists normally of the Shift Manager who holds a Senior Reactor Operator (SRO) license, a Control Room Supervisor (CRS) who also holds an SRO license, three Nuclear Control Operators (NCO) possessing Reactor Operator (RO) licenses, and five Nuclear Equipment Operators (SNEO), one of which is a Radwaste Operator. The Shift Manager is in direct charge of all plant operations during his assigned shift and is directly responsible for the actions of his crew. Technical support assigned to each operating shift and optional staffing is discussed in Section 13.1.2 of the USAR. Individual responsibilities for normal operation are defined in administrative procedures.

When initiating conditions exist that result in one of the EALs being reached, the Shift Manager has the responsibility and authority to declare that an emergency situation exists and to take immediate action in accordance with written operating procedures to mitigate the consequences of the emergency. He will assign the appropriate emergency classification and initiate the necessary EIPs.

13.3.4.2 Onsite Emergency Organization This section of the plan describes the responsibilities of onsite personnel during an event assessed to be an Unusual Event, Alert, Site Area Emergency, or General Emergency.

13.3.4.2.1 Direction/Coordination The Emergency Director is responsible for overall direction and control of the entire activated emergency response organization at River Bend Station and for coordinating the Emergency response with offsite agencies.

The Emergency Director is a member of Senior RBS Management, designated by the Vice President with assigned alternates. The Emergency Director operates from the EOF and maintains overall respon-sibility for the emergency response and subsequent recovery operations. He ensures that the emergency response is well organized and that the various elements of the emergency organization are working as a coordinated group. The Emergency Director has the authority to immediately and unilaterally initiate all emergency actions.

Revision 50 14 April 2025

RBS USAR Section 13.3 Emergency Planning The Emergency Director has the unique responsibility, which may not be delegated, to direct notification of and make protective action recommendations to authorities responsible for implementing offsite emer-gency measures. The Emergency Director assesses emergency conditions and classifies the emergency condition in accordance with the EIPs. The Emergency Director is empowered to authorize major expen-ditures of funds and commit the resources of EOI as required to meet the demands of the emergency situation. The Emergency Director will review information released to the press and offsite authorities concerning the emergency.

The Emergency Plant Manager is responsible for coordinating the onsite emergency response under the direction and control of the Emergency Director.

The Emergency Plant Manager is designated by the General Manager, along with alternates, and is re-sponsible for coordinating all onsite activities and personnel. He operates from the TSC and coordinates all procedures involving the Main Control Room, TSC, OSC, and the Primary Access Point.

The Shift Manager, when initially classifying an emergency condition, will assume the responsibilities of the Emergency Director until properly relieved. The Shift Manager will be in the Main Control Room and will have the responsibility for the manipulation of plant equipment and controls during the declared emergency. The Shift Manager will assess emergency conditions until relieved of this responsibility by the designated Emergency Director, who will assume the responsibility of the Emergency Director.

The Shift Manager will be primarily responsible for emergency direction and control. The Shift Manager or the Control Room Supervisor will be in the control room at all times.

13.3.4.2.2 Plant Staff Emergency Assignments In order to minimize confusion and assist in the control of the emergency response, the emergency orga-nization has been designed so that only one person, or alternate, is responsible for the implementation of specific emergency actions. Responsibilities of key members of the emergency response organization are described in Appendix A.

In order to ensure the continuity of the response, provisions have been made which will provide 24-hr coverage of emergency positions. In addition, the functional areas of responsibility will remain flexible enough to accommodate the needs of the emergency and the availability of personnel. The Administra-tion and Logistics Coordinator will be responsible for assuring continuity of resources while emergency conditions exist.

13.3.4.2.2.1 Plant Operations and Assessment of Operational Aspects Upon declaration of an emergency, the Shift Manager will assume the responsibilities of Emergency Director. Normally two Nuclear Control Operators and one Nuclear Equipment Operator on each shift will have no other duties except to assist in plant operational control from the Main Control Room. A third Nuclear Control Operator may be available and four additional Nuclear Equipment Operators will be available at all times, but collateral responsibilities may require that they assist in repair and/or protective actions. A Nuclear Control Operator may perform the duties of a Nuclear Equipment Operator. The onshift oversight function provides independent verification of emergency classifications.

Assessment of the plant status and degree of safety degradation will be initially evaluated by the Shift Manager. He will base his evaluation on plant instrumentation and reports from technical personnel making actual examination of equipment.

Shift personnel are considered to be immediately available to respond to the emergency situation and initiate emergency response actions. Other station personnel assigned to the emergency response organization may be offsite at the time of initiating events. Table 13.3-17 reflects anticipated reporting times for key personnel.

The TSC, OSC, and the EOF are manned by designated personnel. The EOF is also manned by federal and state officials, as necessary.

A range of protective actions to protect onsite personnel during hostile action is provided to ensure the continued ability to safely shut down the reactor and perform the functions of the emergency plan.

Revision 50 15 April 2025

RBS USAR Section 13.3 Emergency Planning An alternative facility, with communication capabilities for contacting the Control Room, plant security, and the EOF, is available to serve as a staging area for augmented emergency response staff if the site is not accessible.

13.3.4.2.2.2 Notification/Communication Notification of responsible federal, state, and local agencies will be initiated upon the declaration of an emergency by the Shift Manager. Initially, a Nuclear Equipment Operator will normally be designated as a Communicator to conduct the notification from the Main Control Room using the Notification Procedure.

The responsibility for notification/communications will shift from the Control Room to the EOF with the Emergency Director responsibilities. Personnel that are assigned to Communicator positions will have technical backgrounds so that they may effectively transmit information.

13.3.4.2.2.3 Radiological Accident Assessment Upon the occurrence of an off-normal event, the Shift Manager will assess the amount of radiation released and the potential for further releases based upon readouts from installed monitors, in-plant surveys, and samples. A Radiation Protection Technician and a Chemistry Technician will be assigned to each shift to support the Shift Manager in performing radiation surveys and obtaining samples as directed.

The emergency response organization divides radiological accident assessment into onsite and offsite groups. The onsite group is stationed in the OSC and is under the supervision of the Radiological Co-ordinator. Chemistry Technicians under the coordination of the OSC Manager will be available in the OSC to assist in accident assessment. Radiation Protection Technicians can use portable equipment to determine radiation levels and contamination levels from liquid and gaseous releases. Chemistry Tech-nicians can provide samples of reactor coolant and containment atmosphere or suppression pool water to analyze for radioisotopic concentrations when conditions allow the use of the Reactor Sample Sys-tem. Offsite radiation surveys will be directed and the results analyzed by the Radiological Assessment Coordinator at the EOF or the Radiological Coordinator at the TSC if the EOF is not operational. Each offsite team includes two individuals of which at least one is a Radiation Protection Technician. The team is dispatched using appropriate EIPs. Radiological monitoring equipment for use by offsite dose assessment teams is stored in the EOF. The team will obtain samples in the local area as directed for analysis. The particulate filter and iodine cartridge can be evaluated in the field using portable radiation instruments, or may be returned to the site and analyzed using a multichannel analyzer, at the discretion of the Radiological Assessment Coordinator. The offsite teams have dedicated vehicles that are radio equipped for communications with the EOF. In addition, portable radios are available for use by the offsite emergency response teams. Readiness for deployment is expected to be as soon as possible but no later than 90 minutes following notification.

13.3.4.2.2.4 Plant Systems Engineering, Repair, and Corrective Actions A Nuclear Equipment Operator, trained in the operation of the plant radioactive waste system, and two maintenance (electrical, l&C or mechanical) personnel are immediately available to perform repair and corrective actions as directed by the Shift Manager.

Depending upon the type and severity of the emergency, a minimum of eight additional support personnel are available onsite within about 90 minutes. The maintenance and repair personnel will operate out of the OSC.

Technical support will be provided by available RBS personnel. The TSC Manager will coordinate the technical support group which will develop plans and procedures to return the plant to a safe status.

13.3.4.2.2.5 Radiation Protection Coverage Radiation protection coverage will be provided by the Radiation Protection staff. Additional Radiation Protection Technicians are available after notification of a radiological emergency as shown on Table Revision 50 16 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3-17. The Radiation Protection Technicians, working out of the OSC, will perform monitoring, provide radiation protection support, and limit access to radiologically controlled areas. In addition to the radiation protection coverage provided by the Radiation Protection staff, Chemistry and Operations personnel are trained in the use of portable survey instruments. Decontamination of personnel and equipment is under the direction of Radiation Protection personnel in accordance with RBS procedures.

13.3.4.2.2.6 Firefighting The site Fire Brigade will consist of five people on each shift trained in firefighting procedures. A Nuclear Control Operator or Nuclear Equipment Operator will act as the Fire Brigade Leader and keep the Shift Manager informed from the scene of the fire. Additional firefighters may be dispatched to the fire scene as needed and the Fire Brigade will be assisted by the local fire department, as necessary. Firefighting operations will be directed by the Fire Brigade Leader.

13.3.4.2.2.7 First Aid Sufficient numbers of RBS personnel are trained in first aid, so that at least two qualified individuals will be present onsite during each shift. In situations involving radioactive contamination, a Radiation Protection Technician will provide radiation protection coverage for both injured and emergency response personnel. Coordination of first aid operations with offsite support organizations is the responsibility of the Shift Manager.

13.3.4.2.2.8 Search and Rescue Sufficient numbers of RBS personnel receive training in search and rescue techniques such that trained personnel are continuously available to support the emergency response organization. Search and res-cue operations in radiation areas or contaminated areas are supported by Radiation Protection Techni-cians, or an individual trained in the use of portable radiation survey instruments.

13.3.4.2.2.9 Repair and Damage Control Repair and damage control activities during a declared emergency are the responsibility of assigned Operations Support Center personnel. These individuals are familiar with plant equipment and layout such that any required emergency actions can be efficiently and effectively implemented.

13.3.4.2.2.10 Site Access Control and Personnel Accountability RBS security personnel will control both personnel and vehicular access to the site during a declared emergency. These procedures are addressed in the Security Plan and Safeguards Contingency Plan.

The security computer has the capability of tracking persons within the Protected Area and on command can provide the necessary data for personnel accountability.

In the event that the computer system is inoperative, an alternate method of accountability is available.

Following an evacuation, security personnel will verify that all in-plant personnel are accounted for, or will ascertain the names of missing individuals within about 30 minutes of the start of an emergency, and will maintain protected area accountability continuously thereafter. Security personnel will keep the Emergency Plant Manager informed of accountability status.

13.3.4.3 Augmentation of Site Emergency Organization Assistance from other Entergy facilities and outside companies, agencies or organizations may be needed to cope with the emergency. This assistance may be requested by the Emergency Plant Man-ager or the Emergency Director, or by the EOF Manager when authorized by the Emergency Director.

Requests for outside assistance may be coordinated through the Corporate Emergency Center. The EOF Manager will act as liaison for outside agencies providing onsite emergency response support.

Revision 50 17 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3.4.3.1 EOI Headquarters Support At an Alert emergency classification RBS notifies the Nuclear Duty Officer who is responsible for activat-ing the Corporate Emergency Center (CEC).

The CEC performs all corporate support functions during the period of the emergency, including notifi-cations and communications with other organizations not directly involved in the emergency response, such as INPO, Pine Bluff Center, American Nuclear Insurers (ANI), Nuclear Network and other interested organizations. The CEC may coordinate support from other Entergy facilities.

The CEC receives information concerning the emergency from the RBS JIC and keeps Entergy upper management and other Entergy locations informed of emergency activities. A corporate hotline provides a means of direct communications between the CEC and the RBS emergency response organization.

13.3.4.3.2 Local Support Services During the operation of RBS, it may become necessary to request and utilize assistance provided by local organizations. Local support service arrangements have been made with offsite groups to provide on-site aid in the event of an emergency situation, including those resulting from hostile actions, at RBS. Letters of Agreement have been effected with each local support organization that may be called upon to provide direct support to RBS. These letters are reviewed annually to reaffirm each organization's commitment.

Current original signed Letters of Agreement are maintained by Emergency Planning. Appendix B lists the local Letter of Agreement support organizations. The following organizations have agreed to provide direct assistance when requested:

1. West Feliciana Parish Fire Protection District One / St. Francisville Volunteer Fire Department When requested, the West Feliciana Parish Fire Protection District One and the St. Francisville Volunteer Fire Department will provide firefighting assistance.

5. West Feliciana Parish Ambulance Service/ Acadian Ambulance Service Inc.

Both West Feliciana Ambulance Service and the Acadian Ambulance Service Inc. have agreed to provide response to RBS to provide ambulance service for radiologically contaminated or non-contaminated injuries or illnesses requiring emergency transport to either West Feliciana Parish Hospital or Our Lady of the Lake Regional Medical Center.

13.3.4.3.3 Contractor and Other Support Organizations Various contractor and private organizations may provide direct support to RBS during a declared emer-gency. Letters of agreement are not required for these organizations as their assistance is provided based on contractual arrangements.

1. Institute of Nuclear Power Operations As a signatory of the Nuclear Power Plant Emergency Response Voluntary Assistance Agreement, EOI can request personnel or equipment resources to assist in the mitigation of an emergency condition at RBS. Such requests are coordinated by the Institute of Nuclear Power Operations (INPO) in accordance with the INPO Emergency Resource Manual. Copies of the INPO Emergency Resource Manual are available in the TSC and EOF.

2. General Electric When requested, General Electric will implement its BWR Emergency Support Program in accor-dance with the terms of GE Service Information Letter (SIL) No. 324.

13.3.4.3.4 Federal Governmental Agencies Should an emergency occur at RBS, notifications and reports are required to be provided to several governmental agencies. In addition, support and assistance is provided during a declared emergency by some Federal Agencies. Generally, such support is requested and coordinated by the State of Louisiana; however, in some cases direct support to RBS is provided. LDEQ will coordinate local, state and federal technical resources and GOHSEP will coordinate local, state and federal non-technical resources.

1. National Weather Service In the event that the RBS meteorological system becomes inoperable during an emergency event, the National Weather Service (NWS) provides meteorological data which can be used to charac-terize the meteorological conditions in the RBS 10 mile EPZ. The NWS has provided a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months per day telephone number which may be used to obtain this information.

2. Federal Aviation Administration When requested, the Federal Aviation Administration (FAA) will implement airspace control over the RBS 10 mile EPZ.

Revision 50 19 April 2025

RBS USAR Section 13.3 Emergency Planning

3. Department of Energy When requested, the Department of Energy (DOE) will provide offsite radiological assistance during a severe emergency at RBS. Generally this assistance is requested and coordinated by LDEQ.

In addition, DOE operates the Radiation Emergency Assistance Center/Training Site (REACTS) in Oak Ridge, Tennessee. In conjunction with the Oak Ridge Institute for Science and Education (ORISE), REACTS maintains equipment and a trained staff to evaluate and treat individuals who have excessive radioactive materials ingestion or significant overexposures to external radiation in conjunction with severe trauma. This assistance is usually only available to commercial nuclear facilities when the magnitude or uniqueness of the radiological emergency exceeds commercially available resources.

4. United States Coast Guard When requested, the United States Coast Guard (USCG) will control marine traffic and vessel movements within the RBS 10 mile EPZ.

5. U. S. Nuclear Regulatory Commission The Nuclear Regulatory Commission (USNRC) provides assistance and regulatory oversight dur-ing declared emergencies both to RBS and to the State and Local governmental agencies in ac-cordance with their Incident Response Plan (NUREG - 0728). USNRC personnel from the Region IV Office in Texas can arrive at the RBS Site within about 2.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months following notification of a radi-ological emergency. Notifications and continuing communications between RBS and the USNRC are described in other sections of this Plan.

13.3.4.4 State and Local Governmental Agencies The 1 O mile plume exposure pathway EPZ surrounding RBS encompasses five Parishes within the State of Louisiana and the 50 mile ingestion pathway EPZ includes areas of the State of Mississippi. Planning for radiological emergencies has been coordinated with the States of Louisiana and Mississippi, and with the five local Parishes within the 1 O mile EPZ.

13.3.4.4.1 State of Louisiana La. R.S. 30:2104 delegates to the Secretary of the Louisiana Department of Environmental Quality the overall responsibility as the State's lead radiological agency to develop, implement and coordinate specific radiological emergency plans and to respond to any emergency that involves possible or actual release of radioactive materials where it might be necessary to protect public welfare and safety, and the environment, in accordance with the Louisiana Emergency Operations Plan.

The Louisiana Emergency Assistance and Disaster Act of 1993 has delegated to the Director of the Gov-ernor's Office of Homeland Security and Emergency Preparedness (GOHSEP) the overall authority to activate and deactivate the State Emergency Operations Center (EOC) and to exercise overall direction and control of emergency or disaster operations. The Director will provide a disaster management sys-tem embodying all aspects of pre-disaster preparedness and post-disaster response, and will continue disaster prevention and recovery.

The State of Louisiana conducts emergency response activities in accordance with the Louisiana Peace-time Radiological Response Plan (LPRRP) which has been developed by LDEQ. In implementing this plan, the State of Louisiana has entered into a Memorandum of Understanding (MOU) with RBS in order to identify authorities, responsibilities, arrangements for the exchange of information during an accident, coordination of emergency public information dissemination and cooperation in plan development, revi-sion and exercises.

The current signed MOU is maintained in the Emergency Planning file. In order to facilitate coordination between State and RBS emergency response activities, at an Alert or higher emergency classification, EOI will dispatch a representative to the State EOC.

Revision 50 20 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3.4.4.2 River Bend Parishes The five Parishes that make up the 1 O mile EPZ surrounding RBS are referred to in the LPRRP as the River Bend Parishes. West Feliciana Parish, East Feliciana Parish, West Baton Rouge Parish, East Baton Rouge Parish and Pointe Coupee Parish make up the 10 mile plume exposure EPZ. These Parishes activate their emergency organization and facilities in accordance with each Parish's Emergency Plan, which is an Enclosure to the LPRRP. Parish emergency response is implemented under the direction and guidance of LDEQ. Notifications and information exchange between RBS and the five Parishes are conducted in accordance with the LPRRP, MOU between RBS and the State of Louisiana, Parish Enclosures to the LPRRP and the RBS emergency plan and procedures. In order to facilitate coordination of emergency response activities, EOI will dispatch a representative to each Parish EOC at an Alert or higher emergency classification.

13.3.4.4.3 State of Mississippi The Mississippi Emergency Management Agency (MEMA), under the Mississippi Emergency Manage-ment Law of 1980, has the authority to develop, maintain, and implement the Mississippi Radiological Emergency Preparedness Plan (MREPP) and procedures for Fixed Nuclear Facilities in and around the State of Mississippi. It is the responsibility of MEMA to ensure that these plans include planned protec-tive actions for the general population of Mississippi within the 50-mile radius ingestion exposure pathway EPZ of RBS. The RBS Communicator will provide initial notification of an emergency situation to MEMA, the official State Warning Point (SWP). Upon notification of an emergency situation at RBS, MEMA will be responsible for the notification and coordination of the various Mississippi State Response Agencies, as well as the coordination of information to the public of Mississippi. A letter of commitment from the State of Mississippi is on file in Emergency Planning.

13.3.5 Emergency Measures EOI utilizes a method for classifying emergencies which results in four distinct classes. Definitions for each class are described in Section 13.3.3. Criteria for classifying emergency situations in each class are described in Table 13.3-1.

An emergency implementing procedure will be initiated on the basis of measured variables and at speci-fied conditions, or at other times specified by either the Shift Manager or the Emergency Director. These implementing requirements are referred to as Emergency Action Levels (EALs). EALs, as discussed in Section 13.3.3.1, are provided in the EIP used in classifying emergencies.

The initial evaluation by the Shift Manager of abnormal conditions and situations, as well as accidents, will result in the initial classification of the emergency and the implementation of the appropriate proce-dures. The emergency actions will, as appropriate, require notification of the Emergency Director, other emergency organizations and personnel, and reassessment of the conditions and/or situations. A list of implementing procedures and a summary of the procedure's purpose may be found in Appendix F.

Reassessment of the emergency may result in carrying out additional emergency actions, further notifi-cation of emergency organizations and personnel, or reclassification.

13.3.5.1 Activation of the Emergency Organization Notification of the onsite emergency response organization and offsite agencies of an emergency dec-laration is accomplished in accordance with the EIPs. The EIPs also provide for notification message verification, as appropriate.

The shift staffing and augmentation capabilities in the event of an emergency are shown in Table 13.3-17.

The expectation is that emergency response personnel will respond as quickly as possible but no later than the maximum times indicated in the Table.

The emergency response facilities may be activated at any time, and shall be activated at an Alert, Site Area Emergency, or General Emergency declaration. Once activated, the facility shall become Revision 50 21 April 2025

RBS USAR Section 13.3 Emergency Planning operational as soon as possible after declaration of any of these emergency classifications. When facility minimum staffing can be accomplished with onsite personnel, it is the goal to become operational within 45 minutes. Otherwise, it is the goal to be operational in 90 minutes.

At RBS, individuals for each key position will be alerted of an emergency by an automated notification system. If an individual does not respond to the notification system, alternates for the position will be contacted.

To supplement the on-shift staff for emergency situations, the shift staff has been increased beyond the minimum recommended in NUREG-0654. Operations personnel are trained in the use of portable radiation survey instruments so that functions such as search and rescue can be performed without the assistance of radiation protection technicians. These actions provide additional on-shift emergency response capability and ensure that emergencies can be adequately controlled when severe weather or traffic conditions could delay augmentation of the emergency response organization.

13.3.5.2 Assessment Actions The Emergency Director is responsible for the detection, evaluation, and continual assessment of emer-gency conditions.

The initial assessment of emergencies will be accomplished by the normal operating shift under the direction of the Shift Manager. Other members of the station staff, including emergency teams, will be called upon as required. Technical services and support will be obtained from the combination of River Bend station personnel, and outside support organizations as necessary and appropriate.

Accidents involving releases of radioactive materials to the environment require special methods of as-sessment to ensure that responses are appropriate for the protection of the population-at-risk as well as site personnel. Periodic reassessment of the emergency, as described in Table 13.3-7, may result in the reclassification of the emergency and a modification of the type, quantity, and direction of the projected offsite dose estimate. In such cases, appropriate offsite authorities will be notified of any changes in the recommended protective actions.

The ORMS provides information that can be used to determine the gross activity levels of plant effluent paths. The radioactivity levels from ORMS can be automatically or manually input into the offsite dose assessment software.

The ORMS data available on the ERIS computers provides radiological and meteorological data for the offsite dose assessment program. Emergency dose assessments can be made on this system in the MCR, TSC, EOF, and Alternate EOF. Calculations of atmospheric transport and diffusion of radioactive effluents conform to the class A model described in Appendix 2 of NUREG-0654, Rev. 1. The model uses equations, assumptions and dose factors from NUREG-1228 and EPA 400-R-92-001.

Should there be an accidental liquid release via the cooling tower blowdown line; sampling may be performed for comparison against the EPA protective action guide of 0.5 rem per ingestion.

If this comparison indicates that offsite doses exceed the EPA Protective Action Levels for ingestion, the State will be promptly notified. Follow-up sampling and analysis of river water will be instituted to determine actual radioisotopic concentrations in the river. LDEQ and GOHSEP will be updated on the more specific values as soon as the information is available.

Subsequently, LDEQ/ GOHSEP will notify appropriate downstream water users and provide instructions with respect to potential liquid activity arrival time and, if appropriate, water intake shutdown recommen-dations.

Emergency equipment and supplies are maintained at various locations to expedite assessment of radi-ological hazards, both onsite and offsite. Emergency kits are described in Appendix E.

The computer-based radiation monitoring system (ORMS) provides the following outputs to the Main Control Room, Radiation Protection Technicians Clean Work Area, TSC, and EOF:

1. Readout displays for current status of all radiation monitors

2. Trend displays for each monitor channel for the following averages Revision 50 22 April 2025

3. List of all pertinent data base parameters for each channel

4. List of all pertinent data base parameters for each monitor

5. Listing of group displays

6. Group displays of an operator-defined group of channels

7. Alarm group display of channels in alarm

8. Printer capable of printing CRT screens and data Meteorological information is accessed via computer in the TSC, EOF, and Main Control Room. A Com-munication link to the NRC (EROS) is available to relay information to the NRC from the above sources.

The outputs previously listed, along with confirmatory information obtained from offsite assessment equipment, will enable emergency response personnel to continuously assess any risks to the public due to actual or potential radioactive releases and recommend appropriate actions based on the pro-tective action guidelines, as established by the Environmental Protection Agency Manual of Protective Action Guides and Protective Actions for Nuclear Incidents (EPA-400-R-92-001 ). The criteria and guid-ance provided in the EIPs may be used to determine the appropriate Protective Actions.

Accident condition radiation levels in containment will be indicated by high range containment area ra-diation monitors. Radioactive material, which may be released from the containment, can be estimated using the readout from these monitors in conjunction with the graphs in Figures 13.3-25 and 13.3-26, relating area monitor reading in containment versus time for various accident situations.

If the situation warrants, additional information on meteorology, radiation levels, and the environment will be gathered and evaluated to determine exposure rates as well as to confirm and update previous assessments.

In the unlikely event that the primary computerized dose analysis is not available in an accident situation, backup computers with the offsite dose assessment program are available to project offsite doses.

Manual input for the secondary method of offsite dose calculations consists of effluent monitoring, con-tainment monitoring, and meteorological information. ORMS radiological monitoring information is readily available to the TSC and the EOF. If ORMS information is not available, a secondary system consisting of a hotline link between the Main Control Room, TSC, and EOF is provided, as well as status boards in each of these facilities so that radiological monitoring information can be relayed and recorded directly in each Emergency Response Facility.

Secondary sources for meteorological information to the TSC and/or EOF consist of either direct relay of data from the Main Control Room via the hotline or an individual can be dispatched to read the infor-mation at the meteorological tower base station. If the Main Control Room instrumentation is inoperable, additional meteorological information sources are available from the National Weather Service.

Secondary systems provide adequate information for assessment to ensure Emergency Response Fa-cility operation should the primary systems be unavailable.

13.3.5.3 Corrective Actions Normal operating procedures contain steps to take preventative and/or corrective actions in order to avoid or mitigate serious consequences. Plant personnel training is a vital factor in assuring that corrective actions are taken in an expeditious manner.

The instrumentation and control system monitors provide indication/recording and automatically regulate systems necessary for the safe and orderly operation of the unit. These systems provide the operator with all information and controls needed to start up, operate at power, and shut down the unit. They also provide means to cope with abnormal operating conditions should they occur. Control and display of Revision 50 23 April 2025

RBS USAR Section 13.3 Emergency Planning information from these various systems are centralized in the Main Control Room at locations convenient to the operator. This instrumentation and sampling capability provides the basis for initiation of protective actions. Initial actions during radiological incidents will follow the guidance of the RBS EIPs.

13.3.5.4 Protective Actions The EIP used in classifying emergencies has predetermined EALs that, when met or exceeded, will require the implementation of the EIPs. The EIPs contain specific actions to be taken in response to the emergency. In addition, the Shift Manager/Emergency Director/Emergency Plant Manager may im-plement other procedures as necessary. Each implemented procedure has emergency actions that are required. These emergency actions include assessment actions, corrective actions, and protective ac-tions. Protective actions will ensure that individuals, both onsite and offsite, will be notified and actions will be initiated for their protection in the event of an onsite radiological emergency.

Protective actions taken onsite are the responsibility of the Emergency Plant Manager. Recommended protective actions for offsite are the responsibility of the Emergency Director. Actions taken offsite fall under the jurisdiction of the local parishes, LDEQ and Mississippi State Department of Health-Division of Radiological Health (MSDH-DRH).

13.3.5.4.1 Onsite/Offsite Protective Actions 13.3.5.4.1.1 Onsite Protective Actions Protective action for individuals onsite will be taken when a radiological emergency has occurred, or may occur, which will result in concentrations of airborne activity or radiation levels that exceed EALs for a specific area or areas and cannot be readily controlled. In addition, protective actions will be taken for situations such as fires, floods, etc., where individual safety is threatened.

13.3.5.4.1.1.1 Notification Notification of onsite personnel will be accomplished immediately upon classification, escalation and termination of an accident via the plant gaitronics system. The actuation of fire alarms, radiation alarms, telephone calls, and gaitronics announcements, as applicable, will alert onsite personnel to hazardous conditions and to actions they must take. In high noise areas, flashing beacons have been installed to alert personnel in these areas that an evacuation alarm has sounded. Personnel are instructed to exit the area immediately upon activation of the beacon and contact their Supervisor for instructions on the appropriate actions to be taken.

Such actions may be to assemble in emergency teams, to report to emergency response stations, to evacuate specific areas within the site, and/or to evacuate the site. Immediately upon notification by the Emergency Director or Emergency Plant Manager, Security will patrol the owner-controlled area to advise individuals of necessary protective measures to be taken.

13.3.5.4.1.1.2 Protected Area Access Control At the announcement of an Alert, Site Area Emergency, or General Emergency, escorts shall return es-corted visitors to the Primary Access Point for exit processing. Unescorted visitors or contractor/construction personnel are trained in their required actions prior to being granted unescorted access.

Provisions have been included to limit protected area access to EOI personnel and others specifically supporting the emergency response. Access to the protected area is controlled by security officers.

13.3.5.4.1.1.3 Onsite Evacuation and Relocation Onsite evacuations, depending on the nature of the emergency and the extent of the area affected, have been defined as Limited, Building, and Owner Controlled Area Evacuations.

The Emergency Director or Emergency Plant Manager will be responsible for ordering evacuations.

These evacuations will be made after careful consideration of the benefits and risks involved. The Revision 50 24 April 2025

RBS USAR Section 13.3 Emergency Planning Emergency Director or Emergency Plant Manager will evacuate all nonessential personnel during a Site Area or General Emergency. Accountability of all individuals inside the Protected Area will be accom-plished within approximately 30 minutes of the start of such emergency and be maintained continuously thereafter. Action levels for evacuation described below are intended as guidelines and are not to be considered inflexible limits, nor are they to be considered safe levels below which no protective action is indicated.

1. Limited Evacuation - A limited evacuation is defined as the withdrawal of personnel from a single area within a building. A limited evacuation will be implemented when any of the following conditions exists:

(a) Activation of an area radiation monitor high-level alarm.

(b) When airborne radioactive concentrations potentially exceed the derived air concentration specified in Appendix B to 1 0CFR20 as identified by the activation of a continuous air monitor alarm or as deemed necessary by a radiation protection technician's field analysis of a routine or task-oriented air sample.

(c) An unexpected increase of radioactive surface contamination (1) in an area previously des-ignated clean, or (2) in excess of expected levels as identified on a Radiation Work Permit (RWP).

(d) Upon discovery of a radioactive (or suspected radioactive) liquid spill.

(e) Other emergency conditions such as fire that may endanger human life or health as deter-mined by the Shift Manager.

The criteria for these radiation levels and alarms do not apply to anticipated increases or alarms resulting from planned operations. When the need for a Limited Evacuation is iden-tified, personnel in the affected area will proceed in accordance with the EIPs or as directed over the public address system. Personnel involved in a Limited Evacuation will proceed to the nearest unaffected area and will await further instructions regarding accountability and ra-diation monitoring. Personnel evacuating the area in response to a continuous air monitoring alarm or due to adverse conditions in the affected area will immediately contact the control room once they have reached the unaffected area.

2. Building Evacuation - A building evacuation will be declared when either of the following occurs:

(a) Criteria for a Limited Evacuation are exceeded in two or more large operating areas within one building ; or (b) An unexpected or uncontrolled exposure rate in excess of the expected dose rate as indicated by area radiation alarms within a single building.

When a building evacuation is ordered, personnel in the affected area will proceed in accor-dance with the EIPs or as directed over the public address system. Personnel evacuated during a building evacuation will proceed to the Second Floor Hallway of the Services Building for accountability and radiation monitoring, or as otherwise directed.

3. Owner Controlled Area Evacuation - An owner controlled area evacuation is declared whenever significant hazards exist substantially beyond the protected area and extend into the owner con-trolled area.

An owner controlled area evacuation will be ordered anytime a Site Area Emergency or General Emer-gency is declared. All nonessential personnel inside the Protected Area will be directed to the PAP or Alternate Evacuation Point where they will be accounted for.

Accountability process is part of the Security Program and will account for all individuals evacuating the protected area to ascertain the names of missing persons within approximately 30 minutes of the emergency declaration.

If a radiological release above federally approved operating limits has occurred, is occurring, or is immi-nent, all nonessential personnel from the Protected Area will be directed to proceed via private automo-Revision 50 25 April 2025

RBS USAR Section 13.3 Emergency Planning bile, where possible, to the appropriate reception center. Personnel will be monitored for contamination upon arrival at the reception center.

The Station Security Force will take action to ensure that an orderly, safe withdrawal of all nonessential personnel within the Owner Controlled Area takes place. They will be responsible for notification in areas not covered by the public address system. If a radiological release has occurred, is occurring, or is imminent, nonessential personnel will be directed to proceed via private automobile to the appropriate reception center. Personnel will be monitored for contamination upon arrival at the reception center.

Guidance for evacuation is provided in the EIPs.

During an onsite emergency that involves the release of radioactive material, the Emergency Director or Emergency Plant Manager will, as appropriate, request assistance from offsite agencies in controlling access to the owner controlled area. In addition, he will keep the LDEQ and MSDH-DRH informed of projected offsite doses when the EOF is not operational.

13.3.5.4.1.1.4 Evacuation Times The estimated elapsed times, measured from the time of the event declaration to the initial warning of and evacuation of persons in identified areas of the site, are as follows:

1. Limited Evacuation (1 to 10 min.) - This is considered a realistic time to warn and evacuate per-sonnel from a single area within a building.

2. Building Evacuation (10 to 20 min.) - This is considered a realistic time for all nonessential per-sonnel from two or more large operating areas within one building to assemble on the second floor hallway of the Services Building.

3. Owner Controlled Area Evacuation (30 to 60 min.) - This is considered a realistic time to warn and evacuate nonessential personnel within the protected area and the owner controlled area.

13.3.5.4.1.1.5 Monitoring Evacuees All individuals entering the controlled area are required to have in their possession personnel monitoring devices as specified by Radiation Protection Procedures or Radiation Protection personnel. A combi-nation of checking dosimetry devices and questioning evacuees will be used to determine if any high external exposures have been involved in the emergency. For any known or suspected high exposures the permanent badge, if available, will be read as soon as possible and further investigation will be conducted to determine the amount of exposure and the necessary action to be taken.

Monitoring for contamination at the reception centers will be accomplished by using portable instrumen-tation and questioning. Priority for decontamination will be given to persons found with the highest levels of contamination. Any persons suspected or known to have ingested radioactivity will be referred to Louisiana Department of Environmental Quality for further evaluation and treatment.

Facilities are available at the reception centers for decontaminating evacuated, non-essential personnel.

Decontamination rooms located in the reception centers contain the supplies and equipment needed for decontaminating personnel. Personnel monitoring equipment and extra clothing are maintained at these facilities.

13.3.5.4.1.1.6 Search and Rescue Search and Rescue procedures will be implemented during an emergency when either the personnel accountability check shows a person(s) missing or a known individual(s) requires rescue assistance.

Activities requiring excessive exposure will be conducted according to Section 13.3.5.5.1 of this plan.

Any emergency actions that allow exposures above established limits must have real trade-off benefits.

In all situations, the general practice of keeping radiation exposures to a minimum are followed, and all persons subject to exposures must be equipped with adequate dosimetry devices to allow accurate evaluation of their exposures.

Revision 50 26 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3.5.4.1.1.7 Re-entry into Evacuated Areas When an evacuation is conducted as a result of excessive radioactive material release outside normally controlled areas a contamination survey shall be conducted of that area. The area is not returned to normal use until radioactive contamination levels are below the established limit for uncontrolled areas as defined in the Radiation Protection Procedures.

13.3.5.4.1.2 Offsite Protective Actions LDEQ has been charged with the obligation, authority, and overall responsibility for the administration, implementation, application, and coordination of offsite radiological emergency procedures in the event of a radiological incident in the State of Louisiana. The Louisiana Peacetime Radiological Response Plan and its RBS Attachment detail LDEQ's role and delineate responsibilities of planned participants. The Memorandum of Understanding, included in the Louisiana plan, presents the notification and reporting requirements endorsed by LDEQ and EOI.

For the State of Mississippi, the MSDH/DRH is responsible for advising State and local officials on the im-plementation of protective actions. The Mississippi Radiological Emergency Preparedness Plan defines MSDH/DRH responsibilities and functions during a radiological emergency.

A dedicated radio system or Computer Based System provide means for RBS to notify, 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months per day, the five parishes in the 10-mile EPZ, LDEQ, GOHSEP, MEMA, and MHP simultaneously of any emergency classification and any recommended protective responses in a protective action section for the public within 15 minutes of declaration and/or decision. Upon reaching a decision to implement a protective response, the process described in the approved Alert Notification System design report and Louisiana Peacetime Radiological Response Plan will be used to coordinate, verify, and initiate the I PAWS-WEA and IPAWS-EAS messages. Each household within the 10-mile EPZ is sent material which directs members of the public to the Entergy Public Information website in addition to providing means to obtain printed emergency information. The Entergy Public Information website and printed emergency information describe steps to be taken in the event of an accident alert at RBS. Each of the five parishes has an offsite plan compatible with the State of Louisiana that will be exercised periodically, and training will be provided on the offsite emergency plan. This will ensure that the parish plans and the State Plan can be implemented adequately in an orderly fashion with the proper administrative communications to alert the public within a 24-hour period and provide protective action recommendations under the appropriate emergency class.

13.3.5.4.1.2.1 EOI Responsibilities During an Onsite Emergency Event with Offsite Radiological Consequences The responsibilities of EOI during an onsite emergency event with offsite radiological consequences include:

1. Providing the best possible effort to resolve the emergency onsite, and thus alleviate offsite condi-tions.

2. Ensuring that if an accident occurs, the States of Louisiana and Mississippi are notified.

The Emergency Director, or his designee, will notify, via the state/local hotline or Computer Based System, the duty officers of the LDEQ, GOHSEP, the sheriff dispatchers of East Feliciana, Pointe Coupee, West Baton Rouge, and West Feliciana Parishes, and the Emergency Medical Services (EMS) in East Baton Rouge Parish. The Computer Based System and the State and Local Emer-gency Hotline are the primary and secondary means of communications with offsite officials and are dedicated systems. Since they can be activated only from the RBS Main Control Room, TSC, EOF, or Alternate EOF, they are self-verifying systems and can be used to identify persons initiat-ing and receiving the notification. The commercial telephone and radio are backup systems to the Computer Based System and State and Local Emergency hotline. If there is concern about the authenticity of the notification, GOHSEP will contact RBS through a confidential telephone number to verify the initial notification call and will then authenticate the notification to local parishes and other offsite agencies.

Revision 50 27 April 2025

RBS USAR Section 13.3 Emergency Planning If an accident occurs after normal working hours, it is the responsibility of the GOHSEP Duty Officer to ensure that the Secretary of the Louisiana Department of Environmental Quality and the LDEQ receive the initial notification message. In addition, GOHSEP will notify the U.S. Coast Guard, Eighth District, and the FAA, if warranted. GOHSEP will notify the National Warning Center that an emergency condition is in progress at the RBS site.

For Mississippi, the Emergency Director, or his designee, will notify the Mississippi Emergency Management Agency (MEMA). MEMA is the State Warning Point (SWP) for the state of Missis-sippi and will receive the initial notification at the State Emergency Operations Center. MEMA will coordinate with all appropriate local, state, and federal agencies. The alternate SWP will be the Department of Public Safety (DPS).

Initial information will be conveyed using the short Notification Message Form contained in the EIPs.

3. Coordinating EOI actions with those of Federal, State and local agencies involved in offsite aspects of the emergency.

4. Ensuring that all required agencies are advised of the emergency situation.

5. Periodically assessing conditions throughout the emergency and providing current information to those concerned, as it becomes available. Follow-up messages will be disseminated to the appro-priate agencies using the long Notification Message Form. RBS, State and Local agencies have agreed upon the content and format of both the short Notification Message Form and the long Notification Message Form.

13.3.5.4.1.2.2 Public Notification and Information RBS shall ensure that means exist to notify and provide prompt emergency instructions to the population within the plume exposure pathway EPZ. Elements of this notification system are described in Revision D I of the River Bend Station (RBS) Alert and Notification System Evaluation Report (ANS Design Report).

The permanent adult population will be provided emergency information on an annual basis.

EOI, GOHSEP, LDEQ, and the five local parishes shall prepare the information provided. This information will be updated annually and may include, but will not necessarily be limited to educational information on radiation, contacts for additional information, information on respiratory protection, sheltering, evacu-ation routes and relocation centers and special needs of the handicapped and aged. Dissemination of this information will be accomplished by material distributed on an annual basis which directs members of the public to the Entergy Public Information website in addition to providing means to obtain printed emergency information.

Brochures will be used to disseminate information to the transient population in the plume exposure pathway EPZ. This will provide the visitor with information regarding the RBS ANS. Transient population notification information will be maintained and updated periodically.

Members of the public who may be located in the Owner Controlled Area will be provided emergency information which will include, but not be limited to, information on actions to take during an evacuation and evacuation routes. Dissemination of the information will be accomplished by postings at areas where the public may be located and signs at roads entering the Owner Controlled Area.

In addition, EOI will conduct programs annually to acquaint news media personnel with the emergency plan, information concerning radiation, and points of contact for release of public information during an emergency.

During an emergency, the RBS Emergency Director will recommend protective actions to the five lo-cal parishes, LDEQ, and GOHSEP. LDEQ and MSDH/DRH will advise appropriate parish and county agencies of the state of the emergency and recommended protective actions.

The Alert and Notification System (ANS) for the 10-mile EPZ of RBS meets the requirements of NU REG 0654/FEMA-REP-1, Rev.

2.

This system utilizes the Integrated Public Alert and Warning System (IPAWS).

Revision 50 28 April 2025

RBS USAR Section 13.3 Emergency Planning Alert monitoring radios provide supplemental coverage of local special facilities. The persons in the special facilities are advised of an emergency situation by the activation of alert monitor radios which can be activated by each Parish's communicator in the respective parish emergency operations centers or from the RBS EOF. These radios can provide voice transmission of emergency information to the administrators of special facilities located in four of the five local parishes. There are no special facilities located in West Baton Rouge Parish. Active locations of Alert Monitor receivers in the other four Parishes are kept on file in River Bend Station's Emergency Planning Department.

In the event of a General Emergency, the Presidents of the Police Juries and the Mayor President of East Baton Rouge Parish have the authority to order an evacuation of their respective parishes. The Governor of Louisiana has the authority to order evacuations as necessary. The Director of Emergency Management of the parish will coordinate the evacuation. The RBS Emergency Director will authorize periodic updates of the emergency situation.

13.3.5.4.1.2.3 Timing Requirements for Implementation of Offsite Protective Actions EOI has the responsibility to recommend protective actions to the five local parishes within 15 minutes of a decision to make a protective action recommendation. EOI will keep the States of Louisiana and Mississippi informed on the protective actions recommended to the parishes. When possible, EOI will consult with the State of Louisiana prior to making protective action recommendations. Section 13.3.5.2 discusses the accident assessment the utility will perform in order to obtain the information necessary to determine appropriate recommended protective actions.

EPA Protective Action Guides serve as the basis for recommending protective actions to the public.

Projected Total Effective Dose Equivalent (TEDE) and thyroid Committed Dose Equivalent (COE) are the basis for the RBS protective action recommendations to the public. Protective action recommendations for members of the public include sheltering, evacuating or a combination of sheltering and evacuating.

Members of the public in unaffected areas will be recommended to monitor Emergency Alert System broadcasts and prepare to take protective measures as directed by state and local officials.

Protective action recommendations are based on projected radiation exposure. The State of Louisiana and local authorities may take into consideration ambient meteorology, projected duration of the release, evacuation times and degree of protection afforded by local residential units when considering sheltering in lieu of evacuation. Details of the Evacuation Plan within the 10-mile EPZ are contained in the RBS Attachment to the State of Louisiana Plan.

13.3.5.4.2 Use of Protective Equipment and Supplies Protective equipment and supplies listed in an implementing procedure will be utilized to minimize radio-logical exposure and contamination to individuals onsite.

13.3.5.4.3 Contamination Control Measures The details of contamination control measures for onsite areas are contained in the RBS Radiation Protection Program procedures. The following is a brief outline of this program:

1. Radioactive Contamination of Personnel (a) The limit for personnel contamination is specified in Radiation Protection procedures. Person-nel who have become contaminated above these limits will be decontaminated.

If an individual cannot be decontaminated below these limits without damaging the skin, the Radiological Coordinator shall determine what action is to be taken.

(b) During a radiological emergency, Radiation Work Permits (RWPs) will not be required.

(c) Protective clothing is available to be worn by all individuals entering a controlled area. Indi-viduals leaving the controlled area are monitored for contamination before entering the clean area of the station.

Revision 50 29 April 2025

RBS USAR Section 13.3 Emergency Planning (d) Exposure to concentrations of radionuclides in air, which could result in exceeding occupa-tional dose limits, as indicated in 1 0CFR20.1201, shall be limited to the extent possible, con-sistent with mitigation of the emergency.

In general, exposure to airborne concentrations of radionuclides higher than the derived air concentrations (DACs) listed in 1 0CFR20, Appendix B, should be avoided or prevented, but if exposures are necessary, the wearing of appropriate, properly fitted respiratory protection equipment shall be required as determined by the Radiological Coordinator or Radiological Assessment Coordinator, and Potassium-Iodide (Kl) may be ordered by the Emergency Direc-tor or Emergency Plant Manager upon the recommendation of the Radiological Coordinator or Radiological Assessment Coordinator. Periodic portable air samples are taken in selected areas of operation or work activity areas.

2. Area Contamination Control Controls have been established at the station to ensure that levels of fixed and removable con-tamination outside of the controlled areas are maintained at acceptable levels. Limits for fixed and removable contamination are specified in Radiation Protection procedures.

3. Equipment Contamination Control (a) All tools and items of equipment used in the controlled area must be checked for contamination before being taken from the controlled area. If the item is found to be contaminated and decontamination is not practical, the item must remain controlled.

(b) Equipment and tools will not be released for use outside the controlled areas in the plant unless removable contamination is less than the criteria specified in Radiation Protection pro-cedures.

(c) Removal of material from the controlled area with radiation and contamination levels in excess of these limits must be approved for conditional release as specified in the Radiation Protection procedures. Any item approved for conditional release shall meet the requirements of the applicable procedure for radioactive material control.

(d) More detailed guidance is available in the Radiation Protection procedures.

4. Radioactive Contamination of Food and Drinking Water (a) Food and drinking water are not taken into any controlled areas, therefore, contamination of food and drinking water is not a normal occurrence. Should abnormal situations at the station occur which could cause contamination of the food and drinking water supply and actual contamination is suspected, radiological surveys of the food will be performed and samples of the drinking water will be taken and analyzed.

(b) Should any radioactive contamination at or above the minimum detectable activity be found on or in food, the food will be treated as radioactive waste and processed accordingly.

(c) Should radioactive contamination at or above the minimum detectable activity be found in drinking water, the drinking water will then be treated as radioactive liquid waste and treated accordingly. All liquids that are meant to be ingested (i.e., milk, colas, coffee, etc.) are consid-ered drinking water.

(d) Detailed procedures for surveys, samples, and disposal are contained in plant and corporate procedures.

For RBS property outside the protected area fence, radiation monitoring teams are used to deter-mine radiological conditions. For those areas where public access normally occurs, the criteria and measures for contamination control are detailed in the State Plan.

The offsite monitoring teams have the capability to provide an assessment of contamination levels.

Revision 50 30 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3.5.5 Aid to Affected Personnel Provisions have been made to assist personnel who are injured or are radioactively contaminated. First aid and decontamination facilities are available onsite in the Services Building or the injured or contam-inated person may be transported to a hospital offsite. Individuals who may have received excessive radiation exposures are transported to Our Lady of the Lake Regional Medical Center for evaluation.

13.3.5.5.1 Emergency Personnel Exposure Criteria Exposure records are maintained for all station personnel who may enter the controlled access area, including temporary and contract workers. This information is used in determining emergency team as-signments. Responding emergency teams obtain the personnel monitoring devices required for the area which are available in the emergency equipment storage areas and at the access control point to the controlled access area. Dosimeters of legal record (DLR) are processed at intervals determined by the Manager, Radiation Protection. Kl is available to emergency workers and it will be issued as authorized by the Emergency Director or Emergency Plant Manager based on the recommendation of the Radiolog-ical Assessment Coordinator or Radiological Coordinator. The Emergency Director or Emergency Plant Manager must authorize individuals to receive radiation exposures in excess of 1 0CFR20 limits. The individual must volunteer for exposures in excess of 25 Rem.

The exposure guidelines described in Table 13.3-10 are used to expedite decision-making in an accident situation. The EIPs assure that the individual is informed of the relative risk involved with excessive radiation exposure.

13.3.5.5.2 Decontamination and First Aid Facilities for decontaminating personnel are available at RBS in the Radiation Protection Work Area of the Services Building. The personnel decontamination facility consists of a change area, monitoring area, sinks, eyewash supplies, and a shower large enough to allow decontamination of accident victims on stretchers. Specialized equipment is located in this area as is the normal inventory of radiation protection equipment. A first aid room and storage area for emergency equipment and supplies are also located in this area.

Personnel leaving the controlled access area will be evaluated for contamination by use of portable whole body monitors, which also monitor the hands and feet, and/or friskers for self monitoring. During emer-gencies, personnel onsite will be checked, as necessary, for contamination. Facilities for decontaminating personnel evacuated from the plant site area are located at the EOF. An inventory of decontamination supplies and equipment, personnel monitoring equipment, and extra clothing is maintained at these fa-cilities.

Personnel found to be contaminated will undergo decontamination under the direction of Radiation Pro-tection personnel. Measures will be taken to prevent the spread of contamination. Such measures may include isolating affected areas, placing contaminated personnel in clean protective clothing before moving, and decontaminating affected personnel, their clothing, and equipment prior to release. Since most decontamination will occur during recovery or away from high radiation areas, the dose for these personnel should not exceed established exposure guidelines. Detailed guidance for personnel decon-tamination is contained in RBS Radiation Protection procedures.

Radwaste will be handled in the Radwaste Building by following normal procedures. If decontamination is done at the EOF or the River Bend Activity Center, the waste will be contained for later disposal in the plant's liquid radwaste facility. Solid radwaste will be bagged and handled under the Radiation Protection procedures.

Emergency first aid and medical treatment will be given to injured or ill personnel whether the injury or illness is radiation or non-radiation related. Shift personnel trained in first aid will be available onsite on a 24-hr-per-day basis and will assist injured or ill personnel either at the scene of the accident or in the first aid room. If affected personnel must be transported to medical facilities, measures will be taken to prevent the spread of contamination. Exposure limits for ambulance personnel are controlled by the Louisiana State Plan and State regulations.

Revision 50 31 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3.6 Emergency Facilities This section of the Emergency Plan identifies, describes, and gives locations of emergency response facilities, support centers, communication systems, assessment facilities, protective facilities, and first aid and medical facilities. Interface among the Onsite and Offsite Emergency Response Facilities is shown in Figure 13.3-18.

13.3.6.1 Emergency Response Facilities The emergency response facilities are a coordinated group of facilities, separated physically to minimize interference and confusion, and connected by dedicated communication lines to ensure an uninterrupted flow of data and instructions. The emergency response facilities are staffed at the designated level of emergency classification as shown in Figures 13.3-7 and 13.3-9.

The emergency response facilities assure that EOI has the capability to perform the required functions of direction and control, accident assessment (ERIS), communications and notification, onsite and offsite dose assessment (ORMS), interface with state, local, and federal authorities, and recovery and reentry actions. If automated diagnostic functions are not functional in the TSC and EOF adequate secondary measures are provided so that the Emergency Response Facilities can effectively support an emergency.

13.3.6.1.1 Technical Support Center (TSC)

The TSC is the onsite emergency response facility located near the reactor on the third floor of the RBS Services Building inside the Protected Area. The TSC is within close proximity of the Main Control Room to facilitate the interaction between emergency response personnel in both locations. The primary functions of the TSC are as follows :

1. To assist operations personnel in the Main Control Room in mitigating an accident and in returning the reactor to a safe condition by providing engineering, technical, and management support.

2. To coordinate all onsite emergency response activities and exchange information on plant parame-ters with the Emergency Director in the EOF. Plant systems data are available to accomplish these functions.

The overall management of the TSC and onsite emergency response activities is under the direction of the Emergency Plant Manager. In addition to the above primary functions, the TSC is activated at the declaration of an Alert.

The TSC, as part of the RBS Services Building, has been built in accordance with the Uniform Building Code and provides habitability comparable to the Main Control Room. Portable area radiation monitoring equipment is available to the TSC to provide emergency personnel an indication of the levels of radiation present. The TSC ventilation system contains both HEPA and charcoal filters. The TSC has been designed to have approximately 4500 square feet of working area to accommodate EOI personnel with specific TSC responsibilities. In addition, space is provided for pre-designated NRC response personnel.

A general layout of the TSC is shown in Figure 13.3-20.

Communications in the TSC with the Main Control Room, the EOF, the NRC, and other federal, state, and local officials is the same as identified in Section 13.3.6.1.5.4. The ERIS and the ORMS are available in the TSC to provide reliable collection, storage, analysis, display, and communication of information on containment conditions, radiological releases, and meteorology sufficient to determine site and the 10-mile EPZ status, determine changes in status, forecast status, and take appropriate actions. A de-scription of the ERIS is provided in USAR Section 7.7.1.7.

13.3.6.1.2 Operations Support Center (OSC)

The OSC, under the coordination of the OSC Manager, serves as a staging area for site personnel during emergency response and recovery operations. The OSC serves as a:

1. Coordination area for onsite Radiation Protection personnel. From this point, they will be directed to assist in radiological surveys, personnel monitoring, decontamination, reentry, and search and rescue procedures.

2. Coordination area for personnel to conduct plant procedures, (i.e. firefighting, search and rescue, first aid, etc.)

3. Coordination area for Chemistry and Maintenance technicians to be dispatched to areas requiring their support.

The OSC is located in the Services Building. A general layout of the OSC is shown in Figure 13.3-

21. There are direct communications between the OSC, Main Control Room and TSC. If the OSC is evacuated, the Control Room will serve as a backup until the OSC is determined to be habitable.

13.3.6.1.3 Main Control Room The Main Control Room is the primary operations center during events classified as an Unusual Event level emergency and prior to the activation of the other emergency response facilities for more serious emergencies. The necessary resources are available so that the Shift Manager can initiate and coor-dinate all EIPs from the Main Control Room until additional assistance is available. All plant control manipulations are conducted from this area under the Shift Manager's direction.

13.3.6.1.4 Primary Access Point and Alternate Evacuation Point The Primary Access Point, supervised by the Superintendent-Plant Security:

1. Controls the personnel and vehicular ingress and egress to and from the protected area.

2. Serves as the focal point for personnel accountability during a Protected Area Evacuation.

Under the supervision of the Manager Security, security personnel will assist, as required, with emer-gency response and recovery operations. The PAP is equipped with telephone and page-party commu-nications with the Main Control Room, TSC, and the OSC as well as telephone communications with the EOF.

13.3.6.1.5 Emergency Operations Facility (EOF)

The EOF is the emergency response facility located near the reactor site to provide continuous co-ordination and evaluation of EOl's activities during an emergency at RBS having or potentially having environmental consequences. The EOF has been designed to meet the requirements as specified in Supplement 1 to NUREG-0737. The EOF is activated at an Alert or higher level emergency.

Revision 50 33 April 2025

RBS USAR Section 13.3 Emergency Planning The initial function of the EOF is to evaluate the magnitude and effects of actual or potential radioac-tive releases from the plant and to recommend appropriate offsite protective measures and to evaluate emergency conditions for potential emergency classification changes. To accomplish these functions, facilities are provided in the EOF for the evaluation of pertinent radiological, meteorological, and plant system data. The Radiological Assessment Coordinator coordinates the offsite radiological monitoring and analyzes results during emergency and recovery operations.

The overall management of EOI emergency resources is based in the EOF under the direction of the Emergency Director. The EOF Manager reports to the Emergency Director and is responsible for opera-tions within the EOF. The EOF functions are performed in the Main Control Room prior to the activation and staffing of the EOF. The EOF is utilized to coordinate the EOI emergency response activities with those of local, state and federal emergency response organizations, including the NRC and FEMA. The EOF is the location where EOI provides current information on conditions potentially affecting the pub-lic to the NRC and to state and local emergency response agencies. The EOF also functions as the post-accident recovery management center.

At an Alert, EOI will dispatch a technical representative to each of the five parish EOCs within the 10-mile EPZ and the State EOC, to ensure continuity and coordination among EOI, LDEQ, and the affected parishes.

13.3.6.1.5.1 Location The EOF is located within the RBS Training Center outside the plant security boundary but on EOI prop-erty near the intersection of U.S. Highway 61 and the River Bend Power Station Road. The RBS Training Center, in which the EOF is located, is outside the exclusion area and approximately 1.1 miles from the reactor building. The Alternate EOF is in the Entergy Customer Service Center located at 5564 Essen Lane in Baton Rouge, approximately 28 miles southeast of RBS. This facility has adequate accommo-dations to ensure continuous emergency response operations and recovery management should the primary EOF become uninhabitable.

The justification for site location is based upon assuring accurate and timely interface and communica-tions between EOF management personnel and onsite personnel, habitability of the EOF, and meteorol-ogy (predominant wind direction).

To ensure its habitability during an emergency, the EOF has been designed to provide protection against radiological hazards as follows :

1. Exterior Wall Shielding - 8 inches (2.35 gm/cm3) of concrete to provide a Protection Factor of greater than 5.7 for a 0.7 MeV gamma. This figure does not include the 4 inches of brick veneer on the outside walls and is, therefore, lower than the actual value.

2. Ventilation - The EOF Ventilation System contains both HEPA and charcoal filters. The ventilation system is isolated from the external environment, and the HEPA filter is inserted by remote or manual operation.

3. Radiological Monitoring - Instrumentation is provided to allow for determination of radiation levels within the EOF.

13.3.6.1.5.2 Layout The EOF has been designed to have a total area of 6,300 square feet, with approximately 5,700 square feet provided for different functional/staffing areas as indicated. The configuration of the EOF facilitates the flow of information during the decision-making process and provides adequate space to accommo-date all personnel involved in the recovery effort. This facility also allows drills and exercises to be staged while not significantly degrading normal activities throughout the remainder of the RBS Training Center.

A general layout of the EOF is shown in Figure 13.3-22.

13.3.6.1.5.3 Structure The EOF has been designed to meet the following building codes:

Revision 50 43 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3. 7.1.2.2 Emergency Response Exercises An emergency response exercise is conducted at least once every 2 years to demonstrate the effective-ness of the integrated onsite and offsite emergency plans. The exercise is conducted in accordance with NRC/FEMA rules and will include mobilization of State and local personnel and resources adequate to verify the capability to respond to a severe radiological emergency at RBS having offsite consequences.

EOI will provide for a critique of the exercise by qualified observers/evaluators.

In alternate years, when an exercise is not scheduled, EOI conducts a drill that tests the major portions of the onsite emergency plan, procedures and emergency response facilities. State and local agencies are invited to participate to the extent that they wish, and at least partial participation by these agencies is anticipated. These "off-year" drills are conducted and critiqued in a similar manner as the biennial exercises.

The scenario will be varied so that all major elements of the plans and preparedness organizations are tested within an 8 year cycle. Some elements may be demonstrated independent of the biennial exercise and will be evaluated and critiqued. EOI will make provisions to demonstrate unannounced augmentation capabilities between 6:00 p.m. and 4:00 A.M., once every 8 year cycle. Exercises will be conducted under various simulated weather conditions in each 8 year cycle.

13.3. 7.1.2.3 Emergency Response Drills Emergency response drills are held periodically which involve appropriate offsite as well as onsite orga-nizations. These drills are supervised instruction periods aimed at testing, developing, and maintaining skills in a particular area. Drills may be training evolutions, or may be evaluated by designated individ-uals, and are conducted simulating, as closely as practical, actual emergency conditions. Examples of drills that are conducted and their frequency are as follows:

1. Communication Tests Communications with State and local governments within the plume exposure pathway EPZ are tested monthly. Communications with Federal emergency response organizations and states within the ingestion pathway are tested monthly. The HPN and ENS communication systems located in the respective RBS Emergency Response Facilities, and NRC Headquarters are tested monthly.

The notification system used to activate the emergency response organization is tested at least quarterly.

2. Communication Drills Communication drills between the RBS, the States of Louisiana and Mississippi, local EOCs, and station field assessment teams are conducted annually. These communications drills will include the aspect of understanding the content of simulated emergency messages.

3. Fire Drills Fire drills are conducted in accordance with the River Bend Station Fire Protection Program.

4. Medical Emergency Drills A medical emergency drill involving a simulated contaminated individual which contains provisions for participation by the local support services agencies (e.g., ambulance and offsite medical treat-ment facility) is conducted biennially for each local support agency. The medical drill may be per-formed independently or as part of a site drill or biennial exercise.

5. Radiological Monitoring Drills Radiological monitoring drills shall be conducted annually, and will include the collection and analy-sis of sample media such as water, grass, soil, and air from the owner-controlled and nearby offsite areas. These samples will be collected by field monitoring teams.

6. Radiation Protection Drills Revision 50 44 April 2025

RBS USAR Section 13.3 Emergency Planning Radiation protection drills which involve response to and preliminary analyses of simulated elevated airborne samples, as well as direct radiation measurements in the environment, shall be conducted semi-annually.

7. Owner Controlled Area Evacuation and Accountability Drill An evacuation drill, of the Protected Area portion only, is conducted annually to ensure that Pro-tected Area accountability can be performed in the required time.

The capability to notify personnel or members of the public outside the Protected Area fence of an owner controlled area evacuation will be demonstrated at least every six years to ensure notification can be performed within approximately 60 minutes.

8. Site Drills The above drills may be scheduled such that a combination of drills is conducted simultaneously.

Site Drill scenarios are prepared which require involvement of various emergency teams, organi-zations and facilities. Records are maintained of all emergency plan drills for at least five years.

13.3.7.2 Review and Updating the Emergency Plan and Emergency Implementing Procedures The Emergency Plan and the EIPs are reviewed and updated annually by the Emergency Preparedness Manager. The review takes into account: the results of drills and exercises; changes in EOI, Louisiana, and Mississippi policy and plans; and various agreements with offsite agencies. Specific letters of agree-ment in support of the River Bend Station Emergency Plan will be verified annually as part of the review process. Proposed changes, except for editorial, to the Emergency Plan are reviewed by the On-Site Safety Review Committee (OSRC) to consider the impact of the changes on the plan, station policy, de-sign, personnel, operational requirements, and various agreements with offsite agencies. Revisions to the Emergency Plan are signed and implemented by the Emergency Preparedness Manager. The Emer-gency Plan and EIP revision process is controlled by RBS procedures and complies with the provisions of 10 CFR 50.54 (q) and 10 CFR 50, Appendix E, paragraph V. Emergency Plan revisions and updated procedures are distributed by the administrative support group. Emergency Plan revisions are provided to LDEQ.

Familiarization with EIP changes will be accomplished using one, or a combination of the following:

a. Operator and technical training sessions.

b. Tabletop sessions.

c. Required reading sheets, circulated to all affected personnel for significant changes.

The Emergency Telephone Book listing emergency telephone numbers is updated at least quarterly.

13.3.7.3 Emergency Equipment and Supplies The Emergency Preparedness Manager is responsible for the inventory and inspection of designated emergency equipment and supplies. Emergency equipment and supplies and their locations are listed in Appendix E. Detailed listings of emergency equipment and supplies are contained in an implementing procedure. This equipment is inventoried, inspected, and operationally checked, at least quarterly and after each use. Portable radiation monitoring equipment included in these inventories is calibrated in accordance with approved procedures. Equipment, supplies, and parts having shelf lives are checked and replaced as necessary. Any deficiencies found are either cleared immediately or documented for corrective action.

The Emergency Preparedness Manager will assign personnel responsibility for correcting deficiencies.

Revision 50 45 April 2025

RBS USAR Section 13.3 Emergency Planning 13.3.8 Recovery River Bend Station will respond to an emergency event by activating the appropriate level of the emer-gency organization. The Emergency Plant Manager or his designee will assess the conditions resulting from the emergency by observing monitoring instrumentation and evaluating information and data sup-plied by emergency teams. The Emergency Director will ensure that the total population exposure is pe-riodically calculated in accordance with instructions in the Emergency Implementing Procedures (EIPs).

As the actual or potential quantity of radioactive material released is significantly reduced, the Emergency Plant Manager may recommend the termination of the emergency classification, using accepted guide-lines. When procedure guidelines for termination are met, the Emergency Director will terminate the emergency and update his recommendations for offsite radiological response. All emergency and sup-port organizations shall be notified of the termination of the emergency and the initiation of the recovery organization.

The termination of the emergency and transition to the recovery organization can only be effected after plant conditions are stable and the probability of any adverse effect on the general public or damage to the plant has been substantially reduced. The Emergency Director has the responsibility to determine when the emergency situation is stable and entry into the recovery phase can commence.

Recovery operations, under the direction of the Emergency Director, will be directed at restoring River Bend Station to an operational status. Support for this effort may be located in both the TSC and EOF, and will consist of River Bend Station, other EOI, and contracted technical and construction personnel as needed. The basic structure of the Recovery Organization will be dependent on the nature of the accident, the post-accident conditions, and the nature and magnitude of the effort needed to maintain the plant in a safe condition and to restore the plant to pre-accident conditions. In the event that upon termination of the emergency, the plant is capable of routine operations within technical specifications, the Emergency Director in concert with the Emergency Plant Manager may effect the transition to the normal operating organization.

Guidelines for determining when the Site Area or General Emergency situation can be considered stable and the recovery organization can be established (if necessary) are as follows :

1. The reactor is shut down, is in a stable safe configuration and adequate core cooling is available.

2. Excessive releases of radioactivity to the environment have been terminated and no further poten-tial for significant radioactivity releases exists.

3. Offsite concentrations of radioactivity in the atmosphere or in waterways have dispersed to near background levels, excluding ground deposition.

4. The State of Louisiana, the local Parishes and the NRC concur in terminating the emergency.

Following a determination that the emergency conditions no longer exist, the Emergency Director will notify and obtain the concurrence of the Emergency Plant Manager prior to disbanding the emergency organization. The Emergency Director is responsible for assuring that all emergency actions are com-plete and closed out and that the recovery organization is available, adequately staffed, and have been briefed on their responsibilities. The Manager, Radiation Protection as part of the Recovery Organiza-tion, will be responsible for ensuring that all radiological waste produced as a result of an accident at RBS is disposed of properly.

With the securing of emergency operations, an orderly evaluation of (1) the causes and effects of the emergency and (2) the measures necessary to place the station back into operation will commence. Per-sonnel assigned by the RBS General Manager will conduct a limited investigation on the event cause. A detailed investigation on the event and emergency response will be conducted, as appropriate, by the Re-covery Organization in cooperation with outside agencies such as the LDEQ, GOHSEP, MEMA, MSDH, and the NRC. The nuclear safety aspects of the event reports and procedures written for the investigation will be reviewed by the On-Site Safety Review Committee to reduce the probability of recurrence of the event.

Incidents will be reported in accordance with applicable regulations.

Revision 50 46 April 2025

RBS USAR Section 13.3 Emergency Planning To the extent practical, the administrative controls imposed on normal operation will be maintained dur-ing the recovery phase. During recovery operations, the exposure limits specified in 1 0CFR20 will ap-ply. Therefore, entry into radiation areas will be done only when accompanied by Radiation Protection personnel to ensure that radiation levels are at permissible levels. Continuous coverage by Radiation Protection personnel may be waived provided that personnel are adequately instructed in the specific radiological hazard associated with the work to be performed and that personnel entering the area are specifically trained in radiation monitoring techniques.

Plans and procedures for the recovery effort will be developed, as required, to handle the specific details of the accident.

The Main Control Room operators can assess plant status by observing sensor readout. Most sensors have visual and audio alarms. Data will be provided to the Emergency Director as necessary for his assessment. Main Control Room operators will take corrective actions as necessary.

A head count of all personnel onsite is made by the emergency organization. Security log-in sheets and personnel rosters will assist in this assessment.

The radiation monitoring teams will perform these surveys. The radiation levels on the plant's area and process monitoring systems can be obtained from the TSC, OSC, or Main Control Room to assist in these surveys. Surveys of equipment and personnel for contamination are done with portable equipment from the emergency lockers or other devices used routinely.

Surveys conducted by the radiation monitoring teams.

The radiological assessment personnel will be using effluent monitors and meteorological data to make assessments of offsite consequences. Offsite radiation monitoring teams will report survey results to validate calculations as time permits.

For less immediate actions, samples of various environmental media are collected and analyzed by LDEQ, MSDH/DRH, and River Bend Station Personnel.

In the case of offsite consequences, Federal, State, and local agencies are immediately notified in accordance with the Emergency Plan. Predetermined criteria, including a declared General Emergency, are used to initiate various protective actions for the public by the local parishes.

Detailed assessment actions procedures are described in the Emergency Implementing Procedures for various emergency classifications (see Appendix F).

RBS USAR Section 13.3 Emergency Planning APPENDIX F EIP PROCEDURE LISTING Revision 50 April 2025

RBS USAR Section 13.3 Emergency Planning EMERGENCY IMPLEMENTING PROCEDURES The Emergency Implementing Procedures (EIPs) are a set of procedures that have been written to effectively and efficiently implement a response to emergency situations at the River Bend Station (RBS) in accordance with the Emergency Plan. The EIPs have been written to incorporate the necessary elements of NUREG-0654 Revision 1, NUREG 0578 and the recommendations of the Atomic Industrial Forum's (AIF) Nuclear Power Plant Emergency Response Plan. Table F-1 is an EIP Procedure Listing and Table F-2 is a cross-reference of the Emergency Plan and Implementing Procedures.

The EIPs address emergency response functions, including classification of emergencies, activation of the emergency response organization and facilities, notifications, communications, protective action recommendations and emergency response support functions.

Classification of an emergency is accomplished using Emergency Action Levels (EALs) developed from NEl-99-01, Methodology for Development of Emergency Action Levels, Rev. 6. EIP-2-001 contains initiating events that are compared with plant conditions to provide the appropriate emergency classification. When an emergency is classified, the remaining EIPs provide guidance on actions that may be necessary to cope with the emergency situation.

Protective Actions may be necessary to protect the health and safety of the public.

Protective Action recommendations are made to offsite authorities when releases of radioactive materials, projected offsite doses or plant status indicate an actual or potential threat to the health and safety of the public. EIPs provide the necessary guidance to make these recommendations when necessary.

EIPs for Emergency Response Facilities provide guidance for the effective functioning of the emergency response organization during an emergency. They provide guidance to key groups which include Radiation Protection, Security, OSC Staff, TSC Staff, EOF Staff, and the Joint Information Center.

Emergency support activity procedures provide guidance to perform major tasks not usually performed during normal day to day operations. These procedures include, but are not limited to, Offsite Dose Calculation, Offsite Radiological Monitoring, Evacuation, Personnel Accountability, Personnel Search and Rescue, and Recovery.

Emergency support activity procedures provide guidance to maintain the Emergency Response Facilities, Emergency Response Organization, and the Emergency Plan.

Supplementary Procedures (EPPs) provide for the maintenance of the emergency preparedness equipment and the Emergency Planner qualification program at RBS.

Chemistry program procedures provide guidance on the method to estimate core damage and obtain samples. Other support activities are described in the Security and Fire Protection programs.

Subject:

River Bend Station Alert and Notification System (ANS) Evaluation Report

Dear Mr. Waters:

The Federal Emergency Management Agency (FEMA) received the updated Alert and Notification System Evaluation Report - River Bend Station Rev D, dated September 24, 2024. In accordance with 44 C.F.R. § 350.14, FEMA reviews and approves significant plan changes. The changes in the plant's report constitute a significant change. We reviewed and approved the updated report. I am forwarding the report to you for appropriate action.

As noted in the updated ANS Report, the station is switching the primary alert method, from sirens to Integrated Public Alert and Warning System-Wireless Emergency Alert (IP A WS-WEA). The primary notification method will be the Integrated Public Alert and Warning System-Emergency Alert System (IPAWS-EAS). Route alerting and notification will remain as the backup ANS system. We believe the proposed changes are adequate to protect the health and safety of the public living in the vicinity of the plant. These proposed changes provide reasonable assurance that appropriate protective measures can be taken offsite in the event of a radiological emergency.

If you have any questions or concerns, please contact Bruce C. Foreman, Director, Technological Hazards Division at (202) 304-5399.

Alert and Notification System Evaluation Report

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Erin Hoffman Assistant Administrator National Preparedness Directorate Federal Emergency Management Agency 400 C Street, SW Washington, DC 20024 March 3, 2025

SUBJECT:

RIVER BEND STATION ALERT AND NOTIFICATION SYSTEM EVALUATION REPORT

Dear Ms. Hoffman:

On behalf of the U.S. Nuclear Regulatory Commission (NRC), I am responding to your letter dated February 6, 2025, which provided the Federal Emergency Management Agency (FEMA) approval of Revision D of the River Bend Station (RBS) Alert and Notification System Evaluation Report (ANS Design Report) which was received on February 7, 20251.

As described in Revision D of the RBS ANS Design Report, the station switched its primary alert method, from sirens to the Integrated Public Alert and Warning System - Wireless Emergency Alert (I PAWS-WEA) as the primary alerting and notification methods for the 10-mile Emergency Planning Zone. That is, the primary notification method will remain as Emergency Alert System (EAS) but activated through IPAWS. The report also describes RBS maintaining route alerting and notification as the backup ANS system.

Per Section V, Parts A and B of the "Memorandum of Understanding (MOU) between the Department of Homeland Security (DHS/FEMA) and the NRC regarding radiological emergencies, planning, and preparedness," dated July 1, 20242:

"FEMA coordinates all Federal planning for offsite impact of radiological emergencies and takes the lead for assessing offsite radiological emergency response plans and preparedness, makes findings and determinations as to the adequacy and capability of implementing offsite plans, and communicates those findings and determinations to the NRC". As outlined within Section V, Part A, FEMA "Approves Alert and Notification System (ANS) design reports. When the ANS design report undergoes significant changes, including any changes to primary and back-up alert methods, FEMA will allow the NRC to review the ANS design report to ensure that the NRC-regulated aspects of ANS are maintained".

As outlined within Section V, Part B:

"The NRC reviews FEMA's findings and determinations in conjunction with the NRC onsite findings for the purpose of making determinations on the overall state of emergency preparedness. These overall findings and determinations are used by the 1 NRC's Agencywide Documents Access and Management System (ADAMS) Accession No. (ML25041A200) 2 ADAMS (ML24184A043)

NRC to make radiological health and safety decisions in the issuance of licenses and the continued operation of licensed utilization facility to include taking enforcement actions such as notices of violations, civil penalties, orders, or shutdown of operating reactors.

This delineation of responsibilities avoids duplicative efforts by the NRC in preparedness matters."

Additionally, as outlined within Part B, the NRC:

"Reviews FEMA's findings and determinations of offsite plans to determine that the plans, including ANS design reports, are adequate and can be effectively implemented."

The NRC evaluated the updated River Bend ANS Design Report received on February 7, 2025, and found that it contained sufficient information to be considered an adequate submittal for NRC to conduct its review. At this time, the NRC did not identify any licensing basis issues associated with the River Bend ANS Design Report.

Consistent with the roles of each respective agency as set forth in the aforementioned MOU, the NRC conducted a review of the FEMA findings. To aid its review, the NRC utilized the FEMA evaluation criteria and sample template for ANS changes and use of IPAWS3. The NRC review focused on the applicable requirements in Title 10 of the Code of Federal Regulations ( 10 CFR)

Section 50, Appendix E,Section IV.D.3.

The NRC staff conducted a risk-informed assessment and thorough review to determine if there is reasonable assurance that backup capability for alert and notification would be available in the event the primary ANS is unavailable during an emergency. The staff concluded that the back-up capability does exist.

In conclusion, the NRC accepts the findings of FEMA that Revision D of the River Bend Station Alert and Notification System Evaluation Report meets the applicable requirements in 10 CFR 50, Appendix E, Section IV.D.3, and enables the NRC to make a finding of reasonable assurance for public health and safety.

Please feel free to contact my staff, Cindy Rosales-Cooper, Acting Chief, Policy and Oversight Branch at (301) 287-9500 or at Cindy.Rosales-Cooper@nrc.gov, if you have questions.
