This report documents one NRC-identified finding and two self-revealing findings of very low safety significance (Green). All of these findings were determined to involve violations of NRC requirements. Additionally, one licensee identified violation, which was determined to be of very low safety significance, is listed in this report. However, because of the very low safety significance and because they are entered into your corrective action program, the NRC is treating these findings as noncited violations, consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest the violations or the significance of the noncited violations, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: | This report documents one NRC-identified finding and two self-revealing findings of very low safety significance (Green).

The inspectors identified a noncited violation of 10 CFR 50.65(a)(4) involving the licensee's failure to perform an adequate risk assessment while the high pressure core spray room unit cooler was unavailable. Specifically, the licensee assumed that risk would remain green and high pressure core spray would continue to inject into the reactor vessel for 6 hours after room cooling was made unavailable, when, in fact, risk became yellow because high pressure core spray would become unreliable after approximately 60 minutes due to instrument failure in the pump's minimum flow logic. As immediate corrective action, the licensee issued a standing order that administratively considered high pressure core spray unavailable when its room cooler is removed from service. The licensee entered this issue into their corrective action program as Condition | The inspectors identified a noncited violation of 10 CFR 50.65(a)(4) involving the licensee's failure to perform an adequate risk assessment while the high pressure core spray room unit cooler was unavailable.

This issue was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, "Significance Determination Process," Appendix K, "Maintenance Risk Assessment and Risk Management Significance Determination Process," the finding is determined to have very low safety significance (Green) because the incremental core damage probability deficit for the affected time period is less than 1.0E-6 and because the licensee used incorrect risk assumptions that changed the outcome of their risk assessment. There is no crosscutting aspect associated with this violation because the assumptions that lead to the performance deficiency are not indicative of current licensee performance (Section 1R13). | |||

This resulted in a loss of offsite power to the Division III 4160 volt alternating current (Vac) bus while starting a nonsafety-related load with the Division III emergency diesel generator at full power paralleled to the grid. To prevent isolating offsite power to any safety bus, the licensee issued procedure changes to prevent starting loads on the nonsafety-related buses connected to the divisional safety buses while the emergency diesel generators are in test.

The failure to follow the instructions on a radiation work permit is a performance deficiency.

The inspectors determined that the licensee's failure to perform an adequate risk assessment was a performance deficiency. Specifically, the licensee's risk assessment had errors and incorrect assumptions that put the plant in a higher risk category. This issue was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences and because the licensee used incorrect risk assumptions that changed the outcome of their risk assessment. Using Inspection Manual Chapter 0609, "Significance Determination Process," Appendix K, "Maintenance Risk Assessment and Risk Management Significance Determination Process," the finding is determined to have very low safety significance (Green) because the incremental core damage probability deficit for the affected time period is less than 1.0E-6.

The | On September 3, 2009, the Fix-It-Now team technician was dispatched to the turbine building to investigate the cause of a steam seal evaporator problem. The technician logged into the radiologically controlled area on Task 1 of Radiation Work Permit 20091012, Revision 01. This radiation work permit granted the team technician access to all areas of the turbine building that were less than 100 mrem per hour at 30 centimeters. The team technician was not allowed to access high radiation areas or locked high radiation areas. However, the technician entered the 67 foot elevation of the turbine building to observe a controller and obtain a reading. This specific area was posted as a high radiation area. As a result of entering the posted high radiation area, the technician received an electronic dosimeter dose rate alarm. However, the technician failed to hear the alarm due to background noise. This entry resulted in a maximum dose rate of 131 mrem per hour. The dose rate alarm setpoint was 80 mrem per hour. The technician's total dose received during the tour was 6 mrem. The survey record of the feedwater pump area within the turbine building revealed a maximum dose rate of 160 mrem per hour. The licensee's response to this violation was to conduct a human performance error review and initiate a condition report. Additionally, a memorandum was issued to the site and the Entergy fleet re-enforcing the procedural requirements and expectations for entering high radiation areas. | ||

Technical Specification 5.4.1 requires written procedures be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978. Section 7(e)(1), "Radiation Protection Procedures," of Appendix A to Regulatory Guide 1.33 lists procedures for access control to radiation areas, including a radiation work permit system. Procedure EN-RP-105, "Radiation Worker Permits," Revision 8, Section 4.0[5], states that the radiation worker is responsible for reviewing the radiation work permit and complying with the requirements. Radiation Work Permit 20091012, Task 1, did not permit entry into high radiation areas. Contrary to the above, on September 3, 2009, the team technician did not comply with all written instructions provided relative to his radiation work permit, in that he inappropriately entered a high radiation area. Considering this failure to follow procedural guidance when entering the radiologically controlled area was of very low safety significance and it has been entered into the licensee's corrective action program in Condition Report CR-RBS-2009-03953, this violation is being treated as a noncited violation, consistent with Section VI.A of the NRC | Technical Specification 5.4.1 requires written procedures be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.

. The large number of steam leaks (15) following start-up from the refuel outage in mid-October 2009. Two through wall pipe flaws and 13 mechanical joints leaks were reviewed to determine if additional actions were required to maintain plant safety. Six steam leaks were associated with motor operated valve leak off lines. The apparent cause for these leaks was failure to include adequate work instructions to install thread sealant on the leak off line threads prior to reinstallation. Two of the three drain valve leaks stopped after the valves were taken fully shut. In addition the pipe wall flaws were evaluated in the flow accelerated corrosion program for expanded inspections in the areas where they were detected. | |||

Inoperable Greater than the Allowed Outage Time From April 11, 2008, until June 7, 2008, one channel of reactor pressure instrumentation for the anticipated transient without scram recirculation pump trip was outside the technical specification allowed set point range. This occurred because the test instrument used to calibrate the reactor pressure instrumentation on April 11 was out of calibration. This went unrecognized until the next scheduled calibration on June 7. The licensee determined that job performance standards were not adequately defined for the job. Corrective actions included better defining performance standards for the job. This finding was more than minor because it was associated with the configuration control attribute of the Mitigating Systems Cornerstone. The finding was determined to be of very low safety significance (Green) because it was not a design or qualification deficiency confirmed not to result in the loss of operability functionality, did not represent a loss of system safety function, did not represent actual loss of safety function of a single train from greater than its technical specification allowed outage time, did not represent an actual loss of safety function of one or more non-technical specification trains of equipment designated as risk-significant per 10 CFR50.65 for greater that 24 hours and was not potentially risk significant due to seismic, flooding, or severe weather initiating event.

Michael Perito Site Vice President Entergy Operations, Inc. River Bend Station 5485 US Highway 61N St. Francisville, LA 70775 Subject: RIVER BEND STATION - NRC INTEGRATED INSPECTION REPORT 05000458/2010003
Dear Mr. Perito:
On June 30, 2010, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your River Bend Station. The enclosed integrated inspection report documents the inspection findings, which were discussed on July 8, 2010, with Mr. B. Cox, Manager, Operations, and other members of your staff.
The inspections examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
This report documents one NRC-identified finding and two self-revealing findings of very low safety significance (Green). All of these findings were determined to involve violations of NRC requirements. Additionally, one licensee identified violation, which was determined to be of very low safety significance, is listed in this report. However, because of the very low safety significance and because they are entered into your corrective action program, the NRC is treating these findings as noncited violations, consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest the violations or the significance of the noncited violations, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555-0001, with copies to the Regional Administrator, U.S. Nuclear Regulatory Commission, Region IV, 612 E. Lamar Blvd, Suite 400, Arlington, Texas, 76011-4125; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident Inspector at the River Bend Station facility. In addition, if you disagree with the crosscutting aspect assigned to any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region IV, and the NRC Resident Inspector at River Bend Station.

SUMMARY OF FINDINGS
IR 05000458/2010003; 04/01/2010 - 06/30/2010; River Bend Station; Integrated Inspection Report; Maintenance Risk Assessments and Emergent Work Control; Operability Evaluations; Occupational Dose Assessment
The report covered a 3-month period of inspection by resident inspectors and announced baseline inspections by regional based inspectors. Three Green noncited violations were identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609, "Significance Determination Process." Findings for which the significance determination process does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.
A. NRC-Identified Findings and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The inspectors identified a noncited violation of 10 CFR 50.65(a)(4) involving the licensee's failure to perform an adequate risk assessment while the high pressure core spray room unit cooler was unavailable. Specifically, the licensee assumed that risk would remain green and high pressure core spray would continue to inject into the reactor vessel for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after room cooling was made unavailable, when, in fact, risk became yellow because high pressure core spray would become unreliable after approximately 60 minutes due to instrument failure in the pump's minimum flow logic. As immediate corrective action, the licensee issued a standing order that administratively considered high pressure core spray unavailable when its room cooler is removed from service. The licensee entered this issue into their corrective action program as Condition Report CR-RBS-2010-02937.
This issue was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, "Significance Determination Process," Appendix K, "Maintenance Risk Assessment and Risk Management Significance Determination Process," the finding is determined to have very low safety significance (Green) because the incremental core damage probability deficit for the affected time period is less than 1.0E-6 and because the licensee used incorrect risk assumptions that changed the outcome of their risk assessment. There is no crosscutting aspect associated with this violation because the assumptions that lead to the performance deficiency are not indicative of current licensee performance (Section 1R13).
- Green.
A self-revealing noncited violation of Technical Specification 5.4.1.a. was identified for inadequate procedural guidance when surveillance testing the Division III diesel generator. This resulted in a loss of offsite power to the Division III 4160 volt alternating current (Vac) bus while starting a nonsafety-related load with the Division III emergency diesel generator at full power paralleled to the grid. To prevent isolating offsite power to any safety bus, the licensee issued procedure changes to prevent starting loads on the nonsafety-related buses connected to the divisional safety buses while the emergency diesel generators are in test. The licensee entered this issue into their corrective action program as Condition Report CR-RBS-2010-00910.
The finding was more than minor because it affected the equipment performance attribute of the Mitigating Systems Cornerstone and affected the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609.04, Table 4a, the finding was determined to be of very low safety significance (Green) because the finding was not a design or qualification deficiency confirmed not to result in loss of operability or functionality, did not represent a loss of system safety function, did not represent actual loss of safety function of a single train for longer than its technical specification allowed outage time, did not represent an actual loss of safety function of one or more non-technical specification trains of equipment designated as risk significant, and did not screen as potentially risk significant due to seismic, flooding, or severe weather initiating event. There is no crosscutting aspect associated with this violation because this is a historical condition not previously identified by the licensee (Section 1R15).
Cornerstone: Occupational Radiation Safety
- Green.
NRC inspectors reviewed a self-revealing, noncited violation of Technical Specification 5.4.1 for failure to follow radiation work permit instructions. Specifically, a team technician made an unauthorized entry into a posted high radiation area on a radiation work permit that did not grant access to that area. The licensee conducted a review of this event and issued a site-wide memorandum on procedural and management expectations associated with high radiation areas. The licensee entered the finding into the corrective action program as Condition Report CR-RBS-2009-03953.
The failure to follow the instructions on a radiation work permit is a performance deficiency. The performance deficiency was more than minor because it affected the Occupational Radiation Safety Cornerstone. It is associated with the exposure control attribute in that a worker not following radiation work permit instructions does not ensure adequate protection of the worker's health and safety from additional/unintended personal exposure. Using the Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because it did not involve: (1) ALARA planning and controls, (2) an overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to assess dose. Furthermore, the finding had an associated human performance crosscutting aspect in the work practices component because the worker did not use human error prevention techniques, such as self-checking H.4(a)(Section 2RS04).
B. Licensee-Identified Violations
A violation of very low safety significance, which was identified by the licensee, has been reviewed by the inspectors. Corrective actions taken by the licensee have been entered into the licensee's corrective action program. This violation and corrective actions are listed in Section 40A7 of this report.
REPORT DETAILS
Summary of Plant Status
River Bend Station began the inspection period at 100 percent thermal power. On April 10, 2010, the plant reduced reactor power to 95 percent to exercise partially withdrawn control rods and perform turbine bypass valve testing. The plant returned to full power on April 10, 2010. On May 7, 2010, the plant reduced reactor power to 95 percent to exercise partially withdrawn control rods and perform turbine bypass valve testing. The plant returned to full power on May 7, 2010. On June 1, 2010, the plant reduced reactor power to 70 percent to remove reactor feedwater pump 1A from service for shaft seal replacement. The plant returned to 100 percent reactor power on June 7, 2010, and remained at 100 percent reactor power for the remainder of the inspection period.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, and Emergency Preparedness
1R01 Adverse Weather Protection
.1 Summer Readiness for Offsite and Alternate-ac Power
a. Inspection Scope
The inspectors performed a review of preparations for summer weather for selected systems, including conditions that could lead to loss-of-offsite power and conditions that could result from high temperatures. The inspectors reviewed the procedures affecting these areas and the communications protocols between the transmission system operator and the plant to verify that the appropriate information was being exchanged when issues arose that could affect the offsite power system. Examples of aspects considered in the inspectors' review included:
- The coordination between the transmission system operator and the plant's operations personnel during off-normal or emergency events
- The explanations for the events
- The estimates of when the offsite power system would be returned to a normal state
- The notifications from the transmission system operator to the plant when the offsite power system was returned to normal
During the inspection, the inspectors focused on plant-specific design features and the procedures used by plant personnel to mitigate or respond to adverse weather conditions. Additionally, the inspectors reviewed the Updated Safety Analysis Report and performance requirements for systems selected for inspection, and verified that operator actions were appropriate as specified by plant-specific procedures. Specific documents reviewed during this inspection are listed in the attachment. The inspectors also reviewed corrective action program items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into their corrective action program in accordance with station corrective action procedures. The inspectors' reviews focused specifically on the following plant systems:
- Fancy Point 500 kV and 230kV substation
- River Bend transformer yard These activities constitute completion of one readiness for summer weather affect on offsite and alternate-ac power sample as defined in Inspection Procedure 71111.01-05.
b. Findings
No findings were identified.
.2 Readiness for Seasonal Extreme Weather Conditions
a. Inspection Scope
The inspectors performed a review of the adverse weather procedures for seasonal extreme low temperatures. The inspectors verified that weather-related equipment deficiencies identified during the previous year were corrected prior to the onset of seasonal extremes, and evaluated the implementation of the adverse weather preparation procedures and compensatory measures for the affected conditions before the onset of, and during, the adverse weather conditions.
During the inspection, the inspectors focused on plant-specific design features and the procedures used by plant personnel to mitigate or respond to adverse weather conditions. Additionally, the inspectors reviewed the Updated Safety Analysis Report and performance requirements for systems selected for inspection, and verified that operator actions were appropriate as specified by plant-specific procedures. Specific documents reviewed during this inspection are listed in the attachment. The inspectors also reviewed corrective action program items to verify that plant personnel were identifying adverse weather issues at an appropriate threshold and entering them into their corrective action program in accordance with station corrective action procedures. The inspectors' reviews focused specifically on the following plant systems:
- Control building chilled water system
- Standby service water system These activities constitute completion of one readiness for seasonal adverse weather sample as defined in Inspection Procedure 71111.01-05.
b. Findings
No findings were identified.
1R04 Equipment Alignments
Partial Walkdown
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant systems:
- Division II emergency diesel generator
- Main steam positive leakage control system
The inspectors selected these systems based on their risk significance relative to the reactor safety cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could affect the function of the system, and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, Updated Safety Analysis Report, technical specification requirements, administrative technical specifications, outstanding work orders, condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also inspected accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies. The inspectors also verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the corrective action program with the appropriate significance characterization. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of three partial system walkdown samples as defined in Inspection Procedure 71111.04-05.
b. Findings
No findings were identified.
R05 Fire Protection
.1 Quarterly Fire Inspection Tours
a. Inspection Scope
The inspectors conducted fire protection walkdowns that were focused on availability, accessibility, and the condition of firefighting equipment in the following risk-significant plant areas:
- April 4, 2010, diesel generator building, 98-foot elevation; control building, 98-foot elevation
- April 18, 2010, reactor core isolation cooling pump room
- April 28, 2010, control building, 116-foot elevation and 136-foot elevation
- May 13, 2010, auxiliary building, crescent area; E, F, and G tunnels; low pressure core spray pump room; auxiliary building 114-foot elevation and 141-foot elevation
- May 31, 2010, auxiliary building, 141-foot elevation; low pressure core spray pump room; Division I emergency diesel room
- June 8, 2010, fire pump house, 95-foot elevation
- June 21, 2010, control building, 70-foot elevation and 98-foot elevation The inspectors reviewed areas to assess if licensee personnel had implemented a fire protection program that adequately controlled combustibles and ignition sources within the plant; effectively maintained fire detection and suppression capability; maintained passive fire protection features in good material condition; and had implemented adequate compensatory measures for out of service, degraded or inoperable fire protection equipment, systems, or features, in accordance with the licensee's fire plan. The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plant's Individual Plant Examination of External Events with later additional insights, their potential to affect equipment that could initiate or mitigate a plant transient, or their impact on the plant's ability to respond to a security event. Using the documents listed in the attachment, the inspectors verified that fire hoses and extinguishers were in their designated locations and available for immediate use; that fire detectors and sprinklers were unobstructed; that transient material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to be in satisfactory condition. The inspectors also verified that minor issues identified during the inspection were entered into the licensee's corrective action program. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of seven quarterly fire-protection inspection samples as defined in Inspection Procedure 71111.05-05.
b. Findings
No findings were identified.
.2 Annual Fire Protection Drill Observation
a. Inspection Scope
On April 20, 2010, the inspectors observed a fire brigade activation for a fire in the Division II switchgear room. The observation evaluated the readiness of the plant fire brigade to fight fires. The inspectors verified that the licensee staff identified deficiencies, openly discussed them in a self-critical manner at the drill debrief, and took appropriate corrective actions. Specific attributes evaluated were (1) proper wearing of turnout gear and self-contained breathing apparatus; (2) proper use and layout of fire hoses; (3) employment of appropriate fire fighting techniques; (4) sufficient firefighting equipment brought to the scene; (5) effectiveness of fire brigade leader communications, command, and control; (6) search for victims and propagation of the fire into other plant areas; (7) smoke removal operations; (8) utilization of preplanned strategies; (9) adherence to the preplanned drill scenario; and (10) drill objectives.
These activities constitute completion of one annual fire-protection inspection sample as defined in Inspection Procedure 71111.05-05.
b. Findings
No findings were identified.
1R07 Heat Sink Performance

- High pressure core spray room unit cooler emergent maintenance, June 28, 2010 The inspectors selected these activities based on potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that licensee personnel performed risk assessments as required by 10 CFR 50.65(a)(4) and that the assessments were accurate and complete. When licensee personnel performed emergent work, the inspectors verified that the licensee personnel promptly assessed and managed plant risk. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed the technical specification requirements and inspected portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of eight maintenance risk assessments and emergent work control inspection samples as defined in Inspection Procedure 71111.13-05.
b. Findings
Introduction.
The inspectors identified a Green noncited violation of 10 CFR 50.65(a)(4) involving the licensee's failure to perform an adequate risk assessment while the high pressure core spray room unit cooler was unavailable. Specifically, the licensee assumed that risk would remain green (low) and high pressure core spray would continue to inject into the reactor vessel for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, after room cooling was made unavailable, when in fact risk became yellow (elevated) because high pressure core spray would become unreliable after approximately 60 minutes due to instrument failure in the pump's minimum flow logic. The licensee entered this issue into their corrective action program as Condition Report CR-RBS-2010-02937.
Description.
On June 25, 2010, the licensee removed the high pressure core spray pump room unit cooler from service for emergent maintenance. The licensee assessed the plant risk as green using their Equipment-Out-Of-Service risk model. The inspectors challenged the model's assumption that high pressure core spray was available for accident mitigation without heat removal support from its room cooler. Without technical basis, the probabilistic safety analysis assumed that high pressure core spray would continue to inject into the reactor vessel for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after loss of room cooling when, in fact, high pressure core spray would become unreliable after approximately 60 minutes due to instrument failure in the pump's minimum flow logic that could cause the pump to become dead headed, overheat, and mechanically fail. During an accident scenario, the probabilistic safety analysis required high pressure core spray to provide core cooling for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> following plant shutdown at which time the control rod drive pumps would have the capacity to provide adequate core cooling. With the high pressure core spray pump room cooler unavailable, the probabilistic safety analysis fault tree inappropriately modeled high pressure core spray as available for all accident scenarios other than station blackout. This modeling error was originally made in the early 1990s. The licensee determined with high pressure core spray unavailable to perform its mission that the plant safety index was 8.4 (yellow) instead of 9.5 (green). As immediate corrective action, the licensee issued a standing upgrade that administratively considered high pressure core spray unavailable when its room cooler is removed from service.
Analysis.
The inspectors determined that the licensee's failure to perform an adequate risk assessment was a performance deficiency. Specifically, the licensee's risk assessment had errors and incorrect assumptions that put the plant in a higher risk category. This issue was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences and because the licensee used incorrect risk assumptions that changed the outcome of their risk assessment. Using Inspection Manual Chapter 0609, "Significance Determination Process," Appendix K, "Maintenance Risk Assessment and Risk Management Significance Determination Process," the finding is determined to have very low safety significance (Green) because the incremental core damage probability deficit for the affected time period is less than 1.0E-6. There is no crosscutting aspect associated with this violation because the assumptions that lead to the performance deficiency are not indicative of current licensee performance.
Enforcement.
Title 10 CFR 50.65 (a)(4), "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," requires, in part, that prior to performing maintenance activities, the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities. Contrary to the above, on June 25, 2010, the licensee failed to perform an adequate risk assessment before performing maintenance on the high pressure core spray room unit cooler. Since an adequate risk assessment was not performed, the licensee failed to manage the actual risk associated with the activity. Because the finding was of very low safety significance and it has been entered into the licensee's corrective action program as Condition Report CR-RBS-2010-02937, this violation is being treated as a noncited violation, consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000458/2010003-01, "Inadequate Risk Assessment for High Pressure Core Spray Room Unit Cooler Maintenance."
1R15 Operability Evaluations
a. Inspection Scope
The inspectors reviewed the following issues:
- CR-RBS-2010-00910, unplanned trip of Division III 4160 Vac tie breaker, reviewed on May 4, 2010
- CR-RBS-2010-01785, reactor core isolation cooling flow indication, reviewed on May 14, 2010
- CR-RBS-2010-01717, reactor core isolation cooling low oil level, reviewed on May 14, 2010
- CR-RBS-2010-02468, reported main steam positive leakage control system pipe flaw on ASME Code class 1 piping, reviewed on May 28, 2010
The inspectors selected these potential operability issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the evaluations to ensure that technical specification operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the technical specifications and Updated Safety Analysis Report to the licensee personnel's evaluations to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors also reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of four operability evaluations inspection samples as defined in Inspection Procedure 71111.15-04
b. Findings
Introduction.
A Green self-revealing noncited violation of Technical Specification 5.4.1.a. was identified for inadequate procedural guidance when surveillance testing the Division III diesel generator. This resulted in a loss of offsite power to the Division III 4160 volt alternating current (Vac) bus while starting a nonsafety-related load with the Division III emergency diesel generator at full power paralleled to the grid. The licensee entered this issue into their corrective action program as Condition Report CR-RBS-2010-00910.
Description.
On February 24, 2010, while running the Division III emergency diesel generator at full load and parallel to the grid per surveillance test procedure STP-309-0203, "DIV 3 Diesel Generator Operability Test," the 4160 Vac safety-related to nonsafety-related tie breaker (E22-S004-ACB04) tripped on directional over current. The breaker is located electrically between the Division III safety bus and both technical specification required offsite power circuits. The breaker trip resulted in the loss of offsite power to the Division III safety bus and made high pressure core spray and standby service pump 2C inoperable. The directional over current protection causes the breaker to trip and separate the Division III safety bus from offsite power when the diesel is aligned in parallel with the offsite power and excess current flow from the safety-related bus longer than a prescribed time delay. Review of computer data points indicated at the instant before the breaker tripped, operators started the 1,250 horsepower turbine building ventilation chiller motor 1B, per the approved work week schedule. There was insufficient procedural guidance to limit starting large electrical loads while testing emergency diesel generators. This was a performance deficiency. A contributing cause was the failure to consider the load impact of starting HVN-CHL1B during surveillance test scheduling. To prevent isolating offsite power to any safety bus, the licensee issued procedure changes to prevent starting large loads on the nonsafety-related busses connected to the divisional safety busses while the emergency diesel generators are in test.
Analysis.
The failure to provide adequate procedural guidance to prevent the loss of offsite power to the Division III 4160 Vac safety bus during periodic testing was a performance deficiency. The finding was more than minor because it affected the equipment performance attribute of the Mitigating Systems Cornerstone and affected the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609.04, Table 4a, the finding was determined to be of very low safety significance (Green) because the finding was not a design or qualification deficiency confirmed not to result in loss of operability or functionality, did not represent a loss of system safety function, did not represent actual loss of safety function of a single train for longer than its technical specification allowed outage time, did not represent an actual loss of safety function of one or more non-technical specification trains of equipment designated as risk significant, and did not screen as potentially risk significant due to seismic, flooding, or severe weather initiating event. There is no crosscutting aspect associated with this violation because this is a historical condition not previously identified by the licensee and is not reflective of present licensee performance.
Enforcement.
Technical Specification 5.4.1.a. requires that written procedures be established, implemented, and maintained covering the activities in NRC Regulatory Guide 1.33, "Quality Assurance Program Requirements (Operation)," Revision 2. Regulatory Guide 1.33, Appendix A, Section 4.w, requires procedures be prepared, as appropriate, for operation of safety-related systems. Contrary to the above, STP-309-0203, "DIV 3 Diesel Generator Operability Test," did not provide guidance to prevent starting loads during emergency diesel generator surveillance testing that could result in the loss of offsite power. On February 24, 2010, the licensee started the nonsafety-related turbine building ventilation chiller which tripped the safety to nonsafety-related tie breaker and caused a loss of all offsite power to Division III safety-related busses. This resulted in an unplanned inoperability of high pressure core spray and standby service water pump 2C for greater than 35 hours4.050926e-4 days <br />0.00972 hours <br />5.787037e-5 weeks <br />1.33175e-5 months <br />. Because this violation is of very low safety significance and it has been entered into the licensee's corrective action program as Condition Report CR-RBS-2010-00910, this violation is being treated as a noncited violation, consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000458/2010003-02, "Inadequate Procedure Results in Loss of Offsite Power to a 4160 Vac Safety Bus."

Cornerstone:
1EP4 Emergency Action Level and Emergency Plan Changes
a. Inspection Scope
The inspectors performed an in-office review of River Bend Station Procedure EIP-2-001, "Classification of Emergencies," Revision 18. This revision replaced the definition of 'hostile action' with the definition of Nuclear Energy Institute Report 99-01, "Emergency Action Level Methodology," Revision 5, and defined 'security condition' and 'imminent' as used in evaluating emergency action levels. The revision replaced security-related emergency action levels HG1, HS1, HA1, and HU1, and their associated technical bases, with the corresponding emergency action levels from NEI 99-01, "Emergency Action Level Methodology," Revision 5, and made other minor editorial corrections.
This revision was compared to its previous revision, to the criteria of NUREG-0654, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants," Revision 1, to Nuclear Energy Institute 99-01, "Emergency Action Level Methodology," Revisions 4 and 5, and to the standards in 10 CFR 50.47(b) to determine if the revision adequately implemented the requirements of 10 CFR 50.54(q). This review was not documented in a safety evaluation report and did not constitute approval of licensee-generated changes; therefore, this revision is subject to future inspection.
These activities constitute completion of one sample as defined in Inspection Procedure 71114.04-05.
b. Findings
No findings were identified.
1EP6 Drill Evaluation
Training Observations
a. Inspection Scope

These activities constitute completion of the one required sample as defined in Inspection Procedure 71124.04-05.
b. Findings
Introduction.
NRC inspectors reviewed a Green self-revealing, noncited violation of Technical Specification 5.4.1 for failure to follow the radiation work permit instructions while working in the feedwater pump area of the turbine building.
Description.
On September 3, 2009, the Fix-It-Now team technician was dispatched to the turbine building to investigate the cause of a steam seal evaporator problem. The technician logged into the radiologically controlled area on Task 1 of Radiation Work Permit 20091012, Revision 01. This radiation work permit granted the team technician access to all areas of the turbine building that were less than 100 mrem per hour at 30 centimeters. The team technician was not allowed to access high radiation areas or locked high radiation areas. However, the technician entered the 67 foot elevation of the turbine building to observe a controller and obtain a reading. This specific area was posted as a high radiation area. As a result of entering the posted high radiation area, the technician received an electronic dosimeter dose rate alarm. However, the technician failed to hear the alarm due to background noise. This entry resulted in a maximum dose rate of 131 mrem per hour. The dose rate alarm setpoint was 80 mrem per hour. The technician's total dose received during the tour was 6 mrem. The survey record of the feedwater pump area within the turbine building revealed a maximum dose rate of 160 mrem per hour. The licensee's response to this violation was to conduct a human performance error review and initiate a condition report. Additionally, a memorandum was issued to the site and the Entergy fleet re-enforcing the procedural requirements and expectations for entering high radiation areas.
Analysis.
The failure to follow a radiation work permit instruction is a performance deficiency. This finding is greater than minor because it affected the Occupational Radiation Safety cornerstone. It is associated with the exposure control attribute in that a worker not following radiation work permit instructions does not ensure adequate protection of the worker's health and safety from additional/unintended personal exposure. Using the Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because it did not involve: (1) ALARA planning and controls, (2) an overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to assess dose. Furthermore, the finding had an associated human performance cross-cutting aspect in the work practices component because the worker did not use human error prevention techniques, such as self-checking H.4(a).
Enforcement.
Technical Specification 5.4.1 requires written procedures be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978. Section 7(e)(1), "Radiation Protection Procedures," of Appendix A to Regulatory Guide 1.33 lists procedures for access control to radiation areas, including a radiation work permit system. Procedure EN-RP-105, "Radiation Worker Permits," Revision 8, Section 4.0[5], states that the radiation worker is responsible for reviewing the radiation work permit and complying with the requirements. Radiation Work Permit 20091012, Task 1, did not permit entry into high radiation areas. Contrary to the above, on September 3, 2009, the team technician did not comply with all written instructions provided relative to his radiation work permit, in that he inappropriately entered a high radiation area.
Considering this failure to follow procedural guidance when entering the radiologically controlled area was of very low safety significance and it has been entered into the licensee's corrective action program in Condition Report CR-RBS-2009-03953, this violation is being treated as a noncited violation, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000458/2010003-03 "Failure to Follow Radiation Work Permit Instructions."
2RS0 5 Radiation Monitoring Instrumentation
a. Inspection Scope
To verify that the licensee is assuring the accuracy and operability of radiation monitoring instruments that are used to: (1) monitor areas, materials, and workers to ensure a radiologically safe work environment; and (2) detect and quantify radioactive process streams and effluent releases. The instrumentation subject to this review includes equipment used to monitor radiological conditions incident to normal plant operations, including anticipated operational occurrences, and from postulated accidents. The team used the requirements in 10 CFR Part 20 and the licensee's procedures required by technical specifications as criteria for determining compliance. The inspectors interviewed licensee personnel and reviewed the following:
- Selected plant configurations and alignments of process, postaccident, and effluent monitors with descriptions in the Updated Final Safety Analysis Report and the offsite dose calculation manual
- Select instrumentation, including effluent monitoring instrument, portable survey instruments, area radiation monitors, continuous air monitors, personnel contamination monitors, portal monitors, and small article monitors to examine their configurations and source checks
- Calibration and testing of process and effluent monitors, laboratory instrumentation, whole body counter, postaccident monitoring instrumentation, portal monitors, personnel contamination monitors, small article monitors, portable survey instruments, area radiation monitors electronic dosimetry, and air samplers/continuous air monitors
- Reports, self-assessments, and corrective action reports performed since the last inspection related to radiation monitoring instrumentation and follow-up activities, such associated with problem identification, characterization, and tracking Specific documents reviewed during this inspection are listed in the attachment. These activities constitute completion of the one required sample as defined in Inspection Procedure 71124.05-05.

4OA2 Identification and Resolution of Problems
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical Protection
.1 Routine Review of Identification and Resolution of Problems
a. Inspection Scope
As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensee's corrective action program at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. The inspectors reviewed attributes that included the complete and accurate identification of the problem; the timely correction, commensurate with the safety significance; the evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews; and the classification, prioritization, focus, and timeliness of corrective actions. Minor issues entered into the licensee's corrective action program because of the inspectors' observations are included in the attached list of documents reviewed.
These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure, they were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.
b. Findings
No findings were identified.
.2 Daily Corrective Action Program Reviews
a. Inspection Scope
In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's corrective action program. The inspectors accomplished this through review of the station's daily corrective action documents.
The inspectors performed these daily reviews as part of their daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.
b. Findings
No findings were identified.
.3 Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a review of the licensee's corrective action program and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors focused their review on repetitive equipment issues, but also considered the results of daily corrective action item screening discussed in Section 4OA2.2, licensee trending efforts, and licensee human performance results. The inspectors nominally considered the 6-month period of October 1, 2009, through March 31, 2010; although, some examples expanded beyond those dates where the scope of the trend warranted.
The inspectors also included issues documented outside the normal corrective action program in major equipment problem lists, repetitive and/or rework maintenance lists, departmental problem/challenges lists, system health reports, quality assurance audit/surveillance reports, self-assessment reports, and Maintenance Rule assessments. The inspectors compared and contrasted their results with the results contained in the licensee's corrective action program trending reports. Corrective actions associated with a sample of the issues identified in the licensee's trending reports were reviewed for adequacy.
These activities constitute completion of one single semi-annual trend inspection sample as defined in Inspection Procedure 71152-05.
b. Findings
No findings were identified.
.4 Selected Issue Follow-up Inspection
a. Inspection Scope
During a review of items entered in the licensee's corrective action program, the inspectors recognized a corrective action item requiring an equipment failure evaluation concerning:
. The large number of steam leaks (15) following start-up from the refuel outage in mid-October 2009. Two through wall pipe flaws and 13 mechanical joints leaks were reviewed to determine if additional actions were required to maintain plant safety. Six steam leaks were associated with motor operated valve leak off lines. The apparent cause for these leaks was failure to include adequate work instructions to install thread sealant on the leak off line threads prior to reinstallation. Two of the three drain valve leaks stopped after the valves were taken fully shut. In addition the pipe wall flaws were evaluated in the flow accelerated corrosion program for expanded inspections in the areas where they were detected.
2. The inspectors focused on the emergency diesel generators' vibration issues, associated with the combustion air intake system where fatigue cracking have contributed to structural failures since 1989, to determine if the licensee's corrective actions were properly focused on each structural failure and addressed the global cause of the failures.
These activities constitute completion of two in-depth problem identification and resolution sample defined in Inspection Procedure 71152-05.
4OA3 Event Followup
.1 (Closed) Licensee Event Report 05000458/2009003-00: Reactor Pressure Trip Unit
Inoperable Greater than the Allowed Outage Time
From April 11, 2008, until June 7, 2008, one channel of reactor pressure instrumentation for the anticipated transient without scram recirculation pump trip was outside the technical specification allowed set point range. This occurred because the test instrument used to calibrate the reactor pressure instrumentation on April 11 was out of calibration. This went unrecognized until the next scheduled calibration on June 7. The licensee determined that job performance standards were not adequately defined for the job. Corrective actions included better defining performance standards for the job. This finding was more than minor because it was associated with the configuration control attribute of the Mitigating Systems Cornerstone. The finding was determined to be of very low safety significance (Green) because it was not a design or qualification deficiency confirmed not to result in the loss of operability functionality, did not represent a loss of system safety function, did not represent actual loss of safety function of a single train from greater than its technical specification allowed outage time, did not represent an actual loss of safety function of one or more non-technical specification trains of equipment designated as risk-significant per 10 CFR50.65 for greater that 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and was not potentially risk significant due to seismic, flooding, or severe weather initiating event. This licensee identified violation involved a violation of Technical Specification 3.3.4.2.
.2 (Closed) Licensee Event Report 05000458/2010-001-00:
Control Building Chiller Inoperable Greater Than Allowable Outage Time This licensee event report discusses that during accident conditions the control building chillers were not able to remove the design basis heat load while operating with low standby cooling water temperatures. The inspectors identified this issue as a Green noncited violation of Technical Specification 3.7.3 for exceeding the control room air conditioning system thirty day allowed outage time for one inoperable subsystem, the seven day allowed outage time for two inoperable subsystems and failing to enter Modes 3 and 4, as specified. See NRC Inspection Report 05000458/2010002 for additional details. This licensee event report is closed.

On July 8, 2010, the inspectors presented the integrated inspection results to Mr. B. Cox, Acting Site Vice President, and other members of the licensee staff. The licensee acknowledged the issues presented. The inspector asked the licensee whether any materials examined during the inspection should be considered proprietary. No proprietary information was identified.
4OA7 Licensee-Identified Violations
The following violation of very low safety significance was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as a noncited violation.
Technical Specification 3.3.4.2 allows 14 days inoperability of one channel of the anticipated transient without scram recirculation pump trip instrumentation. Contrary to this requirement one channel of instrumentation was outside the technical specification allowed set point range from April 11, 2008, to June 7, 2008. This was identified by the licensee and entered into the licensee's corrective action program as Condition Report CR-RBS-2008-03719. This finding was determined to have very low safety significance.
