SRs shall be met during the MODES or other specified conditions in the Applicability for individual LCOs, unless otherwise stated in the SR. Failure to meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the LCO. Failure to perform a Surveillance within the specified Frequency shall be failure to meet the LCO except as provided in SR 3.0.3. Surveillances do not have to be performed on inoperable equipment or variables outside specified limits. (Emphasis added.)
The definition of Operable - Operability states:
A system, subsystem, train, component, or device shall be OPERABLE or have OPERABILITY when it is capable of performing its specified safety function(s) and when all necessary attendant instrumentation, controls, normal or emergency electrical power, cooling and seal water, lubrication, and other auxiliary equipment that are required for the system, subsystem, train, component, or device to perform its specified safety function(s) are also capable of performing their related support function(s).
(Emphasis added.)
The combination of these requirements and definition makes clear that when a SR is not met, the LCO is not met. In most cases, failure to meet the SR also results in the inoperability of the subject SSC. However, there are instances in which an SSC is not capable of meeting a SR but is still capable of performing its specified safety function(s). To avoid unnecessarily declaring the LCO not met and following the Conditions and Required Actions, the Improved Standard Technical Specifications (ISTS) address several of these instances through Notes stating that the SR is not required to be met. For example:
* NUREG-1431, SR 3.9.4.2, states, "Verify each required containment purge and exhaust valve actuates to the isolation position on an actual or simulated actuation signal." It is modified by a Note which states, "Not required to be met for containment purge and exhaust valve(s) in penetrations closed to comply with LCO 3.9.4.c.1." With the containment purge and exhaust valves closed, verification that the valve will close when Page 2
 
TSTF-541, Rev. 0 an isolation signal is received is not needed to ensure the valves can perform their specified safety functions.
* NUREG-1433, SR 3.1.7.1, states, "Verify each vacuum breaker is closed." It is modified by a Note which states, "Not required to be met for vacuum breakers open when performing their intended function." When the vacuum breaker opens to break vacuum, it is performing its intended safety function and meeting the SR would be contrary to the intended function of the valves.
In other instances in the ISTS, the SR text contains exceptions. For example:
* NUREG-1431, SR 3.5.2.5, states, "Verify each ECCS automatic valve in the flow path that is not locked, sealed, or otherwise secured in position, actuates to the correct position on an actual or simulated actuation signal."
* NUREG-1432, SR 3.7.5.3, states, "Verify each AFW automatic valve that is not locked, sealed, or otherwise secured in position, actuates to the correct position on an actual or simulated actuation signal."
* NUREG-1433, SR 3.5.3.2, states, "Verify each RCIC System manual, power operated, and automatic valve in the flow path, that is not locked, sealed, or otherwise secured in position, is in the correct position."
Need For Change There are SRs in the ISTS that are not required to be met in all circumstances in order for the SSC to perform its specified safety function(s), but that do not contain Notes or exceptions in the SR text. As a result, in some cases the SRs are declared not met and the Conditions and Required Actions entered even though the subject SSC is still Operable (i.e., is capable of performing its specified safety function(s)).
For example, SR 3.6.11.4 states, "Verify each ICS filter bypass damper can be opened." The active phrase "can be opened" means that the SR would not be met if the filter bypass damper is locked open. The purpose of the damper is to conserve the operating life of the filter by bypassing air flow around it unless the damper is opened by a signal. There is no assumption that the damper is able to close post-accident. When the damper is locked opened, the filter is performing its specified safety function (albeit at the cost of more frequent replacement of the filter materials). Nevertheless, in this case the LCO would be declared not met per SR 3.0.1 since the SR is not met, even though the ICS is Operable. This circumstance is adverse to plant safety as it may lead to an unnecessary plant shutdown (a transient) when the system is Operable.
A review of the ISTS identified SRs that do not have exceptions but for which exceptions would be appropriate to avoid unnecessary entry into Conditions and Required Actions. Many system SRs require verification that an SSC actuates on an actual or simulated actuation signal or that it actuates within a specified time. If the SSC is locked in the "actuated," post-accident position, it cannot "actuate" (i.e., move or start working) and the SR is not met. However, if the SSC is not assumed to move following actuation, the SSC is capable of performing its specified safety Page 3
 
TSTF-541, Rev. 0 function with the valve locked in the actuated position. In these cases, the SR should not be required to be met if the SSC is locked in the actuated, post-accident position.

: 3. TECHNICAL EVALUATION System Descriptions The Spray Additive System (NUREG-1430) is a subsystem of the Containment Spray System that assists in reducing the iodine fission product inventory in the containment atmosphere resulting from a Design Basis Accident (DBA). In the event of an accident such as a loss of coolant accident (LOCA), the Spray Additive System will be automatically actuated upon a high containment pressure signal by the Engineered Safety Features Actuation System (ESFAS). The purpose of SR 3.6.7.4 (NUREG-1430) is to verify that each automatic valve in the Spray Additive System flow path actuates to its correct position upon receipt of an actual or simulated actuation signal.
The EVS (NUREG-1430) filters air from the area of the active ECCS components during the recirculation phase of a LOCA. Ductwork, valves or dampers, and instrumentation also form part of the system. During emergency operations, the EVS dampers are realigned, and fans are started to begin filtration. Upon receipt of the actuation signal(s), normal air discharges from the negative pressure area are isolated, and the stream of ventilation air discharges through the system filter trains. The prefilters remove any large particles in the air, and any entrained water droplets present, to prevent excessive loading of the HEPA filters and charcoal adsorbers. The purpose of SR 3.7.12.3 (NUREG-1430) is to verify proper actuation of all train components, Page 8
 
TSTF-541, Rev. 0 including dampers, on an actual or simulated actuation signal. The purpose of SR 3.7.12.5 is to ensure that the system is functioning properly by operating the EVS filter bypass damper.
The FSPVS (NUREG-1430) provides negative pressure in the fuel storage area, and filters airborne radioactive particulates from the area of the fuel pool following a fuel handling accident. The FSPVS consists of portions of the normal Fuel Handling Area Ventilation System (FHAVS), the station EVS, ductwork bypasses, and dampers. The portion of the normal FHAVS used by the FSPVS consists of ducting between the spent fuel pool and the normal FHAVS exhaust fans or dampers, and redundant radiation detectors installed close to the suction end of the FHAVS exhaust fan ducting. The purpose of SR 3.7.13.3 (NUREG-1430) is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal.
The purpose of SR 3.7.13.5 is to ensure that the system is functioning properly by operating the FSPVS filter bypass damper.
The CREVS (NUREG-1430), CREFS (NUREG-1431), CREACS (NUREG-1432), [MREC]
(NUREG-1433), and [CRFA] (NUREG-1434) provide a protected environment from which occupants can control the unit following an uncontrolled release of radioactivity, hazardous chemicals, or smoke. The purpose of SR 3.7.10.3 (NUREG-1430 and NUREG-1431),
SR 3.7.11.3 (NUREG-1432), SR 3.7.4.3 (NUREG-1433), and SR 3.7.3.3 (NUREG-1434) is to verify that each train / subsystem starts and operates on an actual or simulated actuation signal.
The SBACS (NUREG-1431) and SBEACS (NUREG-1432) are required to ensure that radioactive materials that leak from the primary containment into the shield building (secondary containment) following a DBA are filtered and adsorbed prior to exhausting to the environment.
The containment has a secondary containment called the shield building, which is a concrete structure that surrounds the steel primary containment vessel. Between the containment vessel and the shield building inner wall is an annular space that collects any containment leakage that may occur following a LOCA. The SBACS and SBEACS establish a negative pressure in the annulus between the shield building and the steel containment vessel. Filters in the system then control the release of radioactive contaminants to the environment. The SBACS and SBEACS each consist of two separate and redundant trains. Each train includes a heater, [cooling coils,] a prefilter, moisture separators, a HEPA filter, an activated charcoal adsorber section for removal of radioiodines, and a fan. Ductwork, valves and/or dampers, and instrumentation also form part of the system. The system initiates and maintains a negative air pressure in the shield building by means of filtered exhaust ventilation of the shield building following receipt of a safety injection (SI) signal. The purpose of SR 3.6.13.3 (NUREG-1431) and SR 3.6.8.3 (NUREG-1432) is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal. The purpose of SR 3.6.13.4 (NUREG-1431) and SR 3.6.8.4 (NUREG-1432) is to ensure that the system is functioning properly by operating the filter bypass damper.
The ICS (NUREG-1431 and NUREG-1432) is provided to reduce the concentration of fission products released to the containment atmosphere following a postulated accident. The ICS would function together with the Containment Spray and Cooling Systems following a DBA to reduce the potential release of radioactive material, principally iodine, from the containment to the environment. The ICS consists of two 100% capacity, separate, independent, and redundant Page 9
 
TSTF-541, Rev. 0 trains. Each train includes a heater, [cooling coils,] a prefilter, a demister, a high efficiency particulate air (HEPA) filter, an activated charcoal adsorber section for removal of radioiodines, and a fan. Ductwork, valves and/or dampers, and instrumentation also form part of the system.
The system initiates filtered recirculation of the containment atmosphere following receipt of a safety injection signal. The purpose of SR 3.6.11.3 (NUREG-1431) and SR 3.6.10.3 (NUREG-1432) is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal. The purpose of SR 3.6.11.4 (NUREG-1431) and SR 3.6.10.4 (NUREG-1432) is to ensure that the system is functioning properly by operating the ICS filter bypass damper.
The ECCS PREACS (NUREG-1431 and NUREG-1432), in conjunction with other normally operating systems, also provide environmental control of temperature and humidity in the ECCS pump room area and the lower reaches of the Auxiliary Building. Ductwork, valves or dampers, and instrumentation also form part of the system, as well as demisters functioning to reduce the relative humidity of the air stream. During emergency operations, the ECCS PREACS dampers are realigned, and fans are started to begin filtration. Upon receipt of the actuating ESFAS signal(s), normal air discharges from the ECCS pump room isolate, and the stream of ventilation air discharges through the system filter trains. The prefilters or demisters remove any large particles in the air, and any entrained water droplets present, to prevent excessive loading of the HEPA filters and charcoal adsorbers. The purpose of SR 3.7.12.3 (NUREG-1431) and SR 3.7.13.3 (NUREG-1432) is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal. The purpose of SR 3.7.12.5 (NUREG-1431) and SR 3.7.13.5 (NUREG-1432) is to ensure that the system is functioning properly by operating the ECCS PREACS filter bypass damper.
The FBACS (NUREG-1431 and NUREG-1432) filter airborne radioactive particulates from the area of the fuel pool following a fuel handling accident or LOCA. The FBACS, in conjunction with other normally operating systems, also provides environmental control of temperature and humidity in the fuel pool area. FBACS consists of two independent and redundant trains. Each train consists of a heater, a prefilter or demister, a HEPA filter, an activated charcoal adsorber section for removal of gaseous activity (principally iodines), and a fan. Ductwork, valves or dampers, and instrumentation also form part of the system, as well as demisters, functioning to reduce the relative humidity of the airstream. The system initiates filtered ventilation of the fuel handling building following receipt of a high radiation signal. The FBACS is a standby system, parts of which may also be operated during normal plant operations. Upon receipt of the actuating signal, normal air discharges from the building, the fuel handling building is isolated, and the stream of ventilation air discharges through the system filter trains. The purpose of SR 3.7.13.3 (NUREG-1431) and SR 3.7.14.3 (NUREG-1432) is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal. The purpose of SR 3.7.13.5 (NUREG-1431) and SR 3.7.14.5 (NUREG-1432) is to ensure that the system is functioning properly by operating the FBACS filter bypass damper.
The PREACS (NUREG-1431 and NUREG-1432) filter air from the penetration area between containment and the Auxiliary Building. The PREACS consists of two independent and redundant trains. Each train consists of a heater, a prefilter or demister, a HEPA filter, an activated charcoal adsorber section for removal of gaseous activity (principally iodines), and a Page 10
 
TSTF-541, Rev. 0 fan. Ductwork, valves or dampers, and instrumentation, as well as demisters, functioning to reduce the relative humidity of the air stream, also form part of the system. The PREACS is a standby system, parts of which may also operate during normal unit operations. Upon receipt of the actuating signal(s), the PREACS dampers are realigned and fans are started to initiate filtration. The purpose of SR 3.7.14.3 (NUREG-1431) and SR 3.7.15.3 (NUREG-1432) is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal. The purpose of SR 3.7.14.5 (NUREG-1431) and SR 3.7.15.5 (NUREG-1432) is to ensure that the system is functioning properly by operating the PREACS filter bypass damper.
The ECW System (NUREG-1432) provides a heat sink for the removal of process and operating heat from selected safety related air handling systems during a DBA or transient. The ECW System is a closed loop system consisting of two independent trains. Each 100% capacity train includes a heat exchanger, surge tank, pump, chemical addition tank, piping, valves, controls, and instrumentation. An independent 100% capacity chilled water refrigeration unit cools each train. The ECW System is actuated on a Safety Injection Actuation Signal (SIAS) and supplies chilled water to the heating, ventilation, and air conditioning units in Engineered Safety Feature (ESF) equipment areas (e.g., the main control room, electrical equipment room, and safety injection pump area). The purpose of SR 3.7.10.2 (NUREG-1432) is to verify proper automatic operation of the ECW System components and that the ECW pumps will start in the event of any accident or transient that generates an SIAS. This SR also ensures that each automatic valve in the flow paths actuates to its correct position on an actual or simulated SIAS.
The ECCS (NUREG-1433 and NUREG-1434) is designed to limit the release of radioactive materials to the environment following a loss of coolant accident (LOCA) and consists of the High Pressure Coolant Injection (HPCI) System (High Pressure Core Spray (HPCS) System in NUREG-1434), the Core Spray (CS) System (Low Pressure Core Spray (LPCS) System in NUREG-1434), the low pressure coolant injection (LPCI) mode of the Residual Heat Removal (RHR) System, and the Automatic Depressurization System (ADS). The purpose of SR 3.5.1.10 and SR 3.5.2.6 (NUREG-1433) and SR 3.5.1.5 and SR 3.5.2.6 (NUREG-1434) is to verify the automatic initiation logic of HPCI (or HPCS), CS (or LPCS), and LPCI will cause the systems or subsystems to operate as designed, including actuation of the system throughout its emergency operating sequence, automatic pump startup and actuation of all automatic valves to their required positions on receipt of an actual or simulated actuation signal.
The function of the RCIC (NUREG-1433 and NUREG-1434) is to respond to transient events by providing makeup coolant to the reactor. The purpose of SR 3.5.3.5 (NUREG-1433 and NUREG-1434) is to verify the system operates as designed, including actuation of the system throughout its emergency operating sequence; that is, automatic pump startup and actuation of all automatic valves to their required positions on receipt of an actual or simulated actuation signal.
The RHR Containment Spray System (NUREG-1434) is designed to mitigate the effects of primary containment bypass leakage and low energy line breaks. The purpose of SR 3.6.1.7.3 is to verify that each RHR containment spray subsystem automatic valve actuates to its correct position upon receipt of an actual or simulated automatic actuation signal.
Page 11
 
TSTF-541, Rev. 0 The function of the Standby Gas Treatment (SGT) System (NUREG-1433 and NUREG-1434) is to ensure that radioactive materials that leak from the primary containment into the secondary containment following a DBA are filtered and adsorbed prior to exhausting to the environment.
The purpose of SR 3.6.4.3.3 (NUREG-1433 and NUREG-1434) is to verify that each SGT subsystem starts on receipt of an actual or simulated initiation signal. The purpose of SR 3.6.4.3.4 (NUREG-1433 and NUREG-1434) is to verify verifies that the filter cooler bypass damper can be opened and the fan started. This ensures that the ventilation mode of SGT System operation is available.
The HPCS SWS (NUREG-1434) provides cooling water for the removal of heat from components of the Division 3 HPCS system. The purpose of SR 3.7.2.3 (NUREG-1434) is to verify that the automatic valves of the HPCS SWS will automatically switch to the safety or emergency position to provide cooling water exclusively to the safety related equipment on an actual or simulated initiation signal.
Evaluation The proposed change incorporates an allowance excluding valves and dampers that are locked, sealed or otherwise secured in the actuated position from SRs verifying isolation times, or ability to move to the actuated position on an actual or simulated actuation signal. Incorporation of this allowance is consistent with similar requirements in the standard TS.

Valves and dampers affected by the incorporation of this allowance may be locked, sealed or otherwise secured in the actuated position provided that the safety analysis does not assume movement from the actuated position following an accident. While in the actuated position, verification of automatic actuation or valve isolation time is not necessary as the specified safety function is assured. It should be noted that the SR must still be met prior to removing the valve or damper from the locked, sealed or otherwise secured status. To provide additional assurance that the specified safety function is met, the associated Bases are revised to include a Reviewer's Page 13
 
TSTF-541, Rev. 0 Note to ensure that the licensee confirms that the safety analysis does not assume that the valves and dampers affected by incorporation of this SR allowance are assumed to move following an accident.

The proposed change does not affect plant compliance with these regulations.
4.2  No Significant Hazards Consideration Determination The proposed change will revise Surveillance Requirements (SRs) by adding notes or exceptions excluding valves and dampers that are locked, sealed or otherwise secured in the actuated position to consider the SR met when the subject structure, system or component (SSC) is Operable (i.e., is capable of performing its specified safety function). The industry has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, Issuance of Amendment:
: 1.      Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed change revises SRs by adding notes or exceptions excluding from actuation and isolation time testing those valves and dampers that are locked, sealed or otherwise secured in the actuated position. The performance or exclusion of performance of SRs is not an initiator of any accident previously evaluated. As a result, the proposed change has no effect on the probability of any accident previously evaluated. The proposed Page 15
 
TSTF-541, Rev. 0 change excludes performance of certain SRs when the SR is not required to demonstrate that the SSC can perform the safety functions assumed in the accident analysis. As a result, the SSCs continue to perform their mitigating functions and the consequences of any accident previously evaluated are not affected.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
: 2. Does the proposed amendment create the possibility of a new or different kind of accident from any previously evaluated?
Response: No The proposed change revises SRs by adding notes or exceptions excluding from actuation and isolation time testing those valves and dampers that are locked, sealed or otherwise secured in the actuated position. The change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operations. The change does not alter assumptions made in the safety analysis for pump or train operability or actuated valve or damper position.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
: 3. Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No The proposed change revises SRs by adding notes or exceptions excluding from actuation and isolation time testing those valves and dampers that are locked, sealed or otherwise secured in the actuated position. The proposed change does not alter the manner in which safety limits, limiting safety system settings or limiting conditions for operation are determined. The safety analysis assumptions and acceptance criteria are not affected by this change.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Page 16
 
TSTF-541, Rev. 0 4.3    Conclusions In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
: 5. ENVIRONMENTAL CONSIDERATION A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or a significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.
Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

2.0    ASSESSMENT 2.1    Applicability of Published Safety Evaluation
[LICENSEE] reviewed the model safety evaluation dated [DATE] as part of the Federal Register Notice of Availability. This review included a review of the NRC staffs evaluation, as well as the information provided in TSTF-541. [LICENSEE] concluded that the justifications presented in TSTF-541, and the model safety evaluation prepared by the NRC staff are applicable to
[PLANT, UNIT NOS.] and justify this amendment for the incorporation of the changes to the
[PLANT] TS.
[The Traveler and model Safety Evaluation discuss the applicable regulatory requirements and guidance, including the 10 CFR 50, Appendix A, General Design Criteria (GDC). [PLANT] was not licensed to the 10 CFR 50, Appendix A, GDC. The [PLANT] equivalent of the referenced GDC are [REFERENCE INCLUDING UFSAR LOCATION, IF APPLICABLE]. [DISCUSS THE EQUIVALENCE OF THE REFERENCED PLANT-SPECIFIC REQUIREMENTS TO THE APPENDIX A GDC AS RELATED TO THE PROPOSED CHANGE.] This difference does not alter the conclusion that the proposed change is applicable to [PLANT]. ]
2.2    Optional Changes and Variations
[LICENSEE is not proposing any variations or deviations from the TS changes described in the TSTF-541, or the applicable parts of the NRC staffs model safety evaluation dated [DATE].]
[LICENSEE is proposing the following variations from the TS changes described in the TSTF-541 or the applicable parts of the NRC staffs model safety evaluation dated [DATE].]
[The [PLANT] TS utilize different [numbering][and][titles] than the Standard Technical Specifications on which TSTF-541 was based. Specifically, [describe differences between the plant-specific TS numbering and/or titles and the TSTF-541 numbering and titles.] These differences are administrative and do not affect the applicability of TSTF-541 to the [PLANT]
TS.]
2.3    Licensee Verifications
[LICENSEE] confirms the following:
Movement of the affected valves or dampers following an accident is not assumed in the safety analysis for valves and dampers excluded from actuation testing on an actual or simulated signal or from isolation time testing.
 
TSTF-541, Rev. 0
 
==3.0    REGULATORY ANALYSIS==
 
3.1    No Significant Hazards Consideration Determination
[LICENSEE] requests adoption of TSTF-541, "Add Exceptions to Surveillance Requirements When the Safety Function is being Performed," which is an approved change to the Standard Technical Specifications (STS), into the [PLANT NAME, UNIT NOS] Technical Specifications (TS). The proposed amendment modifies the TS Surveillance Requirements (SRs) by adding notes or exceptions to consider the SR met and the associated Limiting Condition for Operation (LCO) met when the subject structure, system or component (SSC) is Operable (i.e., is capable of performing its specified safety function)
[LICENSEE] has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
: 1.      Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed change revises SRs by adding notes or exceptions excluding from actuation and isolation time testing those valves and dampers that are locked, sealed or otherwise secured in the actuated position. The performance or exclusion of performance of SRs is not an initiator of any accident previously evaluated. As a result, the proposed change has no effect on the probability of any accident previously evaluated. The proposed change excludes performance of certain SRs when the SR is not required to demonstrate that the SSC can perform the safety functions assumed in the accident analysis. As a result, the SSCs continue to perform their mitigating functions and the consequences of any accident previously evaluated are not affected.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
: 2.      Does the proposed amendment create the possibility of a new or different kind of accident from any previously evaluated?
Response: No The proposed change revises SRs by adding notes or exceptions excluding from actuation and isolation time testing those valves and dampers that are locked, sealed or otherwise secured in the actuated position. The change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operations. The change does not alter assumptions made in the safety analysis for pump or train operability or actuated valve or damper position.
 
TSTF-541, Rev. 0 Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
: 3.      Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No The proposed change revises SRs by adding notes or exceptions excluding from actuation and isolation time testing those valves and dampers that are locked, sealed or otherwise secured in the actuated position. The proposed change does not alter the manner in which safety limits, limiting safety system settings or limiting conditions for operation are determined. The safety analysis assumptions and acceptance criteria are not affected by this change.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, [LICENSEE] concludes that the proposed change presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
4.0    ENVIRONMENTAL EVALUATION The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

The ECCS subsystems are required to actuate automatically to perform their design functions. This Surveillance verifies that, with a required system initiation signal (actual or simulated), the automatic initiation logic of HPCI, CS, and LPCI will cause the systems or subsystems to operate as designed, including actuation of the system throughout its emergency operating sequence, automatic pump startup and actuation of all automatic valves to their required positions. This SR also ensures that the HPCI System will automatically restart on an RPV low water level (Level 2) signal received subsequent to an RPV high water level (Level 8) trip and that the suction is automatically transferred from the CST to the suppression pool. The LOGIC SYSTEM FUNCTIONAL TEST performed in LCO 3.3.5.1 overlaps this Surveillance to provide complete testing of the assumed safety function.

Reactor steam pressure must be  [920] psig to perform SR 3.5.3.3 and  [150] psig to perform SR 3.5.3.4. Adequate steam flow is represented by [at least 1.25 turbine bypass valves open, or total steam flow  106 lb/hr]. Therefore, sufficient time is allowed after adequate pressure and flow are achieved to perform these SRs. Reactor startup is allowed prior to performing the low pressure Surveillance because the reactor pressure is low and the time allowed to satisfactorily perform the Surveillance is short. The reactor pressure is allowed to be increased to normal operating pressure since it is assumed that the low pressure Surveillance has been satisfactorily completed and there is no indication or reason to believe that RCIC is inoperable. Therefore, these SRs are modified by Notes that state the Surveillances are not required to be performed until 12 hours after the reactor steam pressure and flow are adequate to perform the test.

SR 3.5.1.4 The performance requirements of the ECCS pumps are determined through application of the 10 CFR 50, Appendix K, criteria (Ref. 8). This periodic Surveillance is performed (in accordance with the ASME Code requirements for the ECCS pumps) to verify that the ECCS pumps will develop the flow rates required by the respective analyses. The ECCS pump flow rates ensure that adequate core cooling is provided to satisfy the acceptance criteria of 10 CFR 50.46 (Ref. 10).
The pump flow rates are verified against a system head that is equivalent to the RPV pressure expected during a LOCA. The total system pump outlet pressure is adequate to overcome the elevation head pressure between the pump suction and the vessel discharge, the piping friction losses, and RPV pressure present during LOCAs.
