SUMMARY
DESCRIPTION Entergy Operations, Inc. (Entergy) requests adoption of TSTF-541, "Add Exceptions to Surveillance Requirements for Valves and Dampers Locked in the Actuated Position," which is an approved change to the Standard Technical Specifications (STS), into the Arkansas Nuclear One, Unit 1 (ANO-1), Arkansas Nuclear One, Unit 2 (ANO-2), Grand Gulf Nuclear Station Unit 1 (GGNS), River Bend Station, Unit 1 (RBS) and Waterford Steam Electric Station, Unit 3 (Waterford-3) Technical Specifications (TS). The proposed amendment modifies the TS Surveillance Requirements (SRs) by adding exceptions to consider the SR met when automatic valves or dampers are locked, sealed, or otherwise secured in the actuated position, in order to consider the SR met. Securing the automatic valve or damper in the actuated position may affect the operability of the system or of any supported systems. The associated Limiting Condition for Operation (LCO) is met if the subject structure, system or component (SSC) remains operable (i.e., capable of performing its specified safety function). The following SRs are affected by the proposed change.
1.1 ANO-1 SRs Affected by the Proposed Change For ANO-1, SRs in NUREG-1430, "Standard Technical Specifications Babcock and Wilcox Plants" TS 3.6.7 "Spray Additive System" This is ANO-1 TS 3.6.6. With the replacement of the NaOH Spray Additive System with NaTB baskets, TS 3.6.6 was renamed to Reactor Building (RB)
Sump Buffering Agent. This ANO-1 TS does not require the modification TSTF-541 is offering.
TS 3.7.10 "Control Room Emergency Ventilation System (CREVS)"
This is ANO-1 TS 3.7.9 and SR 3.7.9.3. is affected TS 3.7.12 "Emergency Ventilation System (EVS)"
This is ANO-1 TS 3.7.11 "Penetration Room Ventilation System (PRVS)."
SR 3.7.11.3 is affected.
TS 3.7.13 "Fuel Storage Pool Ventilation System (FSPVS)"
ANO-1 does not have this TS and no changes are required.
1.2 ANO-2 SRs Affected by the Proposed Change The ANO-2 TSs are based on NUREG-0212, "Standard Technical Specifications for Combustion Engineering Pressurized Water Reactors." As such, the ANO-2 TS numbering generally differs from that of the current Improved Standard Technical
CNRO2021-00019 Enclosure Page 3 of 16 Specifications (ISTS), and the actual TS wording may also differ. Therefore, each ANO-2 TS affected by TSTF-541 is listed below with any differences or variations discussed individually. ANO-2 has implemented TSTFs based on NUREG-1432 ISTS in the past by adapting the wording from the TSTF to the ANO-2 current TS format and verifying that it continues to meet the intent of the applicable TSTF NRC safety evaluation. The same has been done for TSTF-541.
For ANO-2, SRs in NUREG-1432, "Standard Technical Specifications Combustion Engineering Plants" TS 3.6.8 "Shield Building Exhaust Air Cleanup System (SBEACS) (Dual)"
ANO-2 does not have this TS and no changes are required.

ANO-2 does not have this TS and no changes are required.
TS 3.7.14 "Fuel Building Air Cleanup System (FBACS)"
ANO-2 does not have this TS and no changes are required.
TS 3.7.15 "Penetration Room Exhaust Air Cleanup System (PREACS)"
ANO-2 does not have this TS and no changes are required.
1.3 GGNS SRs Affected by the Proposed Change For GGNS, SRs in NUREG-1434, "Standard Technical Specifications General Electric BWR/6 Plants" TS 3.5.1 "Emergency Core Cooling Systems (ECCS) Operating" This is GGNS TS 3.5.1 and SR 3.5.1.5 is affected.
CNRO2021-00019 Enclosure Page 4 of 16 TS 3.5.2 "Reactor Pressure Vessel Water Inventory Control" This TS is not part of standard TS (NUREG-1434) but was added under TSTF-542. SR 3.5.2.7 is affected.
The GGNS TS have incorporated, via Amendment 218 issued by the NRC on May 23, 2019 (ML19084A218), TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control," which had not been incorporated into the standard TS on which TSTF-541 was based. The changes in TSTF-541 are equally applicable to SR 3.5.2.7 added by TSTF-542. Therefore, the TSTF-541 allowance is added to SR 3.5.2.7.
TS 3.5.3 "Reactor Core Isolation Cooling (RCIC) System" This is GGNS TS 3.5.3 and SR 3.5.3.5 is affected.
TS 3.6.1.7 "Residual Heat Removal (RHR) Containment Spray System" This is GGNS TS 3.6.1.7 and SR 3.6.1.7.4 is affected.
TS 3.6.4.3 "Standby Gas Treatment (SGT) System" This is GGNS TS 3.6.4.3 and SR 3.6.4.3.3 is affected.
TS 3.7.1 "Standby Service Water (SSW) System and Ultimate Heat Sink (UHS)"
This is GGNS TS 3.7.1 and SR 3.7.1.4 is affected.
TS 3.7.2 "High Pressure Core Spray (HPCS) Service Water System (SWS),"
This is GGNS TS 3.7.2 and SR 3.7.2.2 is affected.
TS 3.7.3 "Control Room Fresh Air (CRFA) System" This is GGNS TS 3.7.3 and SR 3.7.3.3 is affected.
1.4 RBS SRs Affected by the Proposed Change For RBS, SRs in NUREG-1434, "Standard Technical Specifications General Electric BWR/6 Plants" TS 3.5.1 "Emergency Core Cooling Systems (ECCS) Operating" This is RBS TS 3.5.1 and SR 3.5.1.5 is affected.
TS 3.5.2 "Reactor Pressure Vessel Water Inventory Control" This TS is not part of standard TS (NUREG-1434) but was added under TSTF-542. SR 3.5.2.6 is affected.
CNRO2021-00019 Enclosure Page 5 of 16 The RBS TS have incorporated, via Amendment 193 issued by the NRC on November 7, 2018 (ML18267A341), TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control," which had not been incorporated into the standard TS on which TSTF-541 was based. The changes in TSTF-541 are equally applicable to SR 3.5.2.6 added by TSTF-542. Therefore, the TSTF-541 allowance is added to SR 3.5.2.6.
TS 3.5.3 "Reactor Core Isolation Cooling (RCIC) System" This is RBS TS 3.5.3 and SR 3.5.3.5 is affected TS 3.6.1.7 "Residual Heat Removal (RHR) Containment Spray System" This TS is not included in the RBS TS. No changes required.
TS 3.6.4.3 "Standby Gas Treatment (SGT) System" This is RBS TS 3.6.4.3. SR 3.6.4.3.3 and SR 3.6.4.3.4 are affected.
TS 3.7.1 "Standby Service Water (SSW) System and Ultimate Heat Sink (UHS)"
This is RBS TS 3.7.1 and SR 3.7.1.5 is affected.
TS 3.7.2, "High Pressure Core Spray (HPCS) Service Water System (SWS),"
This TS is not part of the RBS TSs and no SR are affected.
TS 3.7.3, "Control Room Fresh Air (CRFA) System" This is RBS TS 3.7.2 and SR 3.7.2.3 is affected.
1.5 Waterford-3 SRs Affected by the Proposed Change The Waterford-3 TSs are based on NUREG-0212, "Standard Technical Specifications for Combustion Engineering Pressurized Water Reactors." As such, the Waterford-3 TS numbering generally differs from that of the current ISTS, and the actual TS wording may also differ. Therefore, each Waterford-3 TS affected by TSTF-541 is listed below with any differences or variations discussed individually. Waterford-3 has implemented TSTFs based on NUREG-1432 ISTS in the past by adapting the wording from the TSTF to the Waterford-3 current TS format and verifying that it continues to meet the intent of the applicable TSTF NRC safety evaluation. The same has been done for TSTF-541.
For Waterford-3, SRs in NUREG-1432, "Standard Technical Specifications Combustion Engineering Plants" TS 3.6.8 "Shield Building Exhaust Air Cleanup System (SBEACS) (Dual)"
This is Waterford-3 TS 3.6.6.1 "Shield Building Ventilation System."
SR 4.6.6.1.d.2 and SR 4.6.6.1.d.3 are affected.
CNRO2021-00019 Enclosure Page 6 of 16 TS 3.6.10 "Iodine Cleanup System (ICS) (Atmospheric and Dual)"
Waterford-3 does not have this TS and no changes are required.
TS 3.7.10 "Essential Chilled Water (ECW)"
This is Waterford-3 TS 3.7.12 "Essential Services Chilled Water System."
Waterford-3 SRs do not require verification of automatic dampers or valves repositioning on an actuation signal. Therefore, no changes are required.
TS 3.7.11 "Control Room Emergency Air Cleanup System (CREACS)"
This is Waterford-3 TS 3.7.6.1 "Control Room Emergency Filtration System."
The current Waterford-3 TS SRs that would be affected by this TSTF already contain "except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position" Therefore, no changes are required.
TS 3.7.13 "Emergency Core Cooling System (ECCS) Pump Room Exhaust Air Cleanup System (PREACS)"
This TS is consolidated along with TS 3.7.15 into Waterford-3 TS 3.7.7 and titled "Controlled Ventilation Area System." SR 4.7.7.d.2 and SR 4.7.7.d.3 are affected.
TS 3.7.14 "Fuel Building Air Cleanup System (FBACS)"
Waterford-3 has a Fuel Handling Building Ventilation System; however, this system does not have a specified TS function for Waterford-3 and is not included in the Waterford-3 TSs. As such, Waterford-3 does not have a system that is considered equivalent to NUREG-1432 TS 3.7.14. Therefore, no changes are required.
TS 3.7.15 "Penetration Room Exhaust Air Cleanup System (PREACS)"
This TS is consolidated along with TS 3.7.13 into Waterford-3 TS 3.7.7 and titled "Controlled Ventilation Area System." SR 4.7.7.d.2 and SR 4.7.7.d.3 are affected.
While the proposed exceptions permit automatic valves and dampers that are locked, sealed, or otherwise secured in the actuated position to be excluded from the SR in order to consider the SR met, the proposed changes will not permit a system that is made inoperable by locking, sealing, or otherwise securing an automatic valve or damper in the actuated position to be considered operable. As stated in the SR 3.0.1 (for ANO-2 and Waterford-3 SR 4.0.1) Bases, "Nothing in this Specification, however, is to be construed as implying that systems or components are OPERABLE when: a. The systems or components are known to be inoperable, although still meeting the SRs."
CNRO2021-00019 Enclosure Page 7 of 16 2.0 DETAILED DESCRIPTION 2.1 Applicability of Safety Evaluation Entergy has reviewed the safety evaluation for TSTF-541 provided to the Technical Specifications Task Force in a letter dated December 10, 2019. This review included a review of the NRC staffs evaluation, as well as the information provided in TSTF-541.
As described herein, Entergy has concluded that the justifications presented in TSTF-541 and the safety evaluation prepared by the NRC staff are applicable to ANO-1, ANO-2, GGNS, RBS, and Waterford-3 and justify this amendment for the incorporation of the changes to the ANO-1, ANO-2, GGNS, RBS, and Waterford-3 TS.
Entergy acknowledges that under the proposed change, the affected valves and dampers may be excluded from the SR when locked, sealed or otherwise secured in the actuated position. However, if the safety analysis assumes movement from the actuated position following an event, or the system is rendered inoperable by locking, sealing, or otherwise securing the valve or damper in the actuated position, then the system cannot perform its specified safety function and is inoperable regardless of whether the SR is met.
Entergy acknowledges for components for which the SR allowance can be utilized, the SR must be verified to have been met within its required Frequency after removing the valve or damper from the locked, sealed or otherwise secured status. If the SR exception is utilized to not test the actuation of a valve or damper and the specified Frequency of the SR is exceeded without testing the component, the SR must be performed on the component when it is returned to service in order to meet the SR.
2.2 Variations Entergy is proposing the following variations from the TS changes described in TSTF-541 or the applicable parts of the NRC staffs safety evaluation.
2.2.1 ANO-1 2.2.1.1 The ANO-1 TS utilize different numbering and titles than the Standard Technical Specifications on which TSTF-541 was based. Specifically, NUREG-1430 TS 3.7.10 "Control Room Emergency Ventilation System (CREVS)" is TS 3.7.9 for ANO-1. As such, the SR affected by this change is SR 3.7.9.3.
NUREG-1430 TS 3.7.12 "Emergency Ventilation System (EVS)" is TS 3.7.11 "Penetration Room Ventilation System (PRVS)" for ANO-1. As such, the SR affected by this change is SR 3.7.11.3.
These differences are administrative and do not affect the applicability of TSTF-541 to the ANO-1 TS.
CNRO2021-00019 Enclosure Page 8 of 16 2.2.1.2 The ANO-1 TS contain requirements that differ from the Standard Technical Specifications on which TSTF-541 was based, but these differences do not affect the applicability of the TSTF-541 justification.
NUREG-1430 TS 3.7.10 for ANO-1 is TS 3.7.9. TS 3.7.9 as approved for ANO-1, has slightly different wording but still meet the intent of NUREG-1430.
NUREG SR 3.7.10.3 reads, "Verify [each CREVS train actuates] [or the control room isolates] on an actual or simulated actuation signal."
ANO-1 SR 3.7.9.3 reads, "Verify the CREVS automatically isolates the Control Room and switches into a recirculation mode of operation on an actual or simulated actuation signal." This is an SR that will be modified by the TSTF. This variance does not change the intent of the TSTF change.
NUREG-1430 TS 3.7.12 for ANO-1 is TS 3.7.11. SR 3.7.11.3, as approved for ANO-1, has slightly different wording but still meet the intent of NUREG-1430.
NUREG LCO 3.7.12 Title is "Emergency Ventilation System (EVS)."
This TS for ANO-1 is TS 3.7.11 and is titled "Penetration Room Ventilation System (PRVS)." This variance has no effect of the text change being made to SR 3.7.11.3.
2.2.1.3 The ANO-1 Technical Specifications contain a Surveillance Frequency Control Program. Therefore, the Frequency for the affected SRs is "In accordance with the Surveillance Frequency Control Program." This has no effect on the applicability of the proposed change.
2.2.2 ANO-2 2.2.2.1 The current ANO-2 TS format, numbering, and terminology is consistent with the NUREG-0212 Standard Technical Specifications (STS). The NUREG-0212 STS numbering for surveillance requirements differs from the numbering in NUREG-1432, "Standard Technical Specifications Combustion Engineering Plants," (i.e., the Improved STS which were used to develop TSTF-541).
Specifically, NUREG-1432 TS 3.7.11 "Control Room Emergency Air Cleanup System (CREACS)" is TS 3.7.6.1 for ANO-2. As such, the SR affected by this change is SR 4.7.6.1.2.b.
This variation is administrative, consistent with the current ANO-2 TS, as well as the underlying NUREG-0212 basis for the current ANO-2 TS and does not affect the applicability of TSTF-541 to the ANO-2 TS.
CNRO2021-00019 Enclosure Page 9 of 16 2.2.2.2 The ANO-2 TS contain requirements that differ from the Standard Technical Specifications on which TSTF-541 was based, but these differences do not affect the applicability of the TSTF-541 justification.
NUREG-1432 TS 3.7.11 is titled "Control Room Emergency Air Cleanup System (CREACS)," which for ANO-2 is TS 3.7.6.1 "Control Room Emergency Ventilation and Air Conditioning System". The ANO-2 TS 3.7.6.1 combines the requirements of NUREG-1432 TS 3.7.11 "Control Room Emergency Air Cleanup (CREACS)" and NUREG-1432 TS 3.7.12 "Control Room Emergency Air Temperature Control System (CREATCS)"
into one TS with the required Actions and Surveillance Requirements of the aforementioned NUREG-1432 TS that are applicable to ANO-2. TS 3.7.6.1 as approved for ANO-2, has slightly different wording, but still meets the intent of NUREG-1432.
NUREG SR 4.7.6.3 reads, "Verify each CREACS train actuates on an actual or simulated actuation signal."
ANO-2 SR 4.7.6.1.2, reads, "Each control room emergency air filtration system shall be demonstrated OPERABLE:"
o SR 4.7.6.1.2.b reads "In accordance with the Surveillance Frequency Control Program by verifying that on a control room high radiation signal, either actual or simulated, the system automatically isolates the control room and switches into a recirculation mode of operation." This is an SR that will be modified by the TSTF. This variance does not change the intent of the TSTF change.
2.2.2.3 The ANO-2 Technical Specifications contain a Surveillance Frequency Control Program. Therefore, the Frequency for the affected SRs is "In accordance with the Surveillance Frequency Control Program." This has no effect on the applicability of the proposed change.
2.2.3 GGNS 2.2.3.1 The GGNS TS utilize different numbering than the Standard Technical Specifications on which TSTF-541 was based. Specifically, NUREG-1434 TS 3.6.1.7 "Residual Heat Removal (RHR) Containment Spray System," SR 3.6.1.7.3 is SR 3.6.1.7.4 for GGNS NUREG-1434 TS 3.7.1 "Standby Service Water (SSW)System and Ultimate Heat Sink (UHS)" SR 3.7.1.6 is SR 3.7.1.4 for GGNS.
NUREG-1434 TS 3.7.2,"High Pressure Core Spray (HPCS) Service Water System (SWS)" SR 3.7.2.3 is SR 3.7.2.2 for GGNS.
CNRO2021-00019 Enclosure Page 10 of 16 These differences are administrative and do not affect the applicability of TSTF-541 to the GGNS TS.
2.2.3.2 The GGNS TS contain requirements that differ from the Standard Technical Specifications on which TSTF-541 was based, but these differences do not affect the applicability of the TSTF-541 justification.
NUREG-1434 TS 3.6.4.3, "Standby Gas Treatment (SGT) System,"
SR 3.6.4.3.4 is not used in the GGNS TS.
2.2.3.3 The GGNS TS have incorporated TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control," which had not been incorporated into the standard TS on which TSTF-541 was based. The changes in TSTF-541 are equally applicable to new GGNS SR 3.5.2.7 added by TSTF-542. Therefore, the TSTF-541 allowance is added to SR 3.5.2.7.
2.2.3.4 The GGNS Technical Specifications contain a Surveillance Frequency Control Program. Therefore, the Frequency for the affected SRs is "In accordance with the Surveillance Frequency Control Program." This has no effect on the applicability of the proposed change.
2.2.4 RBS 2.2.4.1 The RBS TS utilize different numbering and titles than the Standard Technical Specifications on which TSTF-541 was based. Specifically, NUREG-1434 TS 3.7.1 "Standby Service Water (SSW) System and Ultimate Heat Sink (UHS)" SR 3.7.1.6 is SR 3.7.1.5 for RBS.
NUREG-1434 TS 3.7.3, "Control Room Fresh Air (CRFA) System" is TS 3.7.2 for RBS. As such, the SR affected by this change is SR 3.7.2.3.
These differences are administrative and do not affect the applicability of TSTF-541 to the RBS TS.
2.2.4.2 The RBS TS contain requirements that differ from the Standard Technical Specifications on which TSTF-541 was based, but these differences do not affect the applicability of the TSTF-541 justification.
NUREG-1434 TS 3.6.1.7 "Residual Heat Removal (RHR) Containment Spray System." The RBS TS do not contain this TS and therefore the SR 3.6.1.7.3 does not exist.
NUREG-1434 TS 3.7.2, "High Pressure Core Spray (HPCS) Service Water System (SWS)." The RBS TS do not contain this TS and therefore the SR 3.7.2.3 does not exist.
2.2.4.3 The RBS TS have incorporated TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control," which had not been incorporated into the
CNRO2021-00019 Enclosure Page 11 of 16 standard TS on which TSTF-541 was based. The changes in TSTF-541 are equally applicable to new RBS SR 3.5.2.6 added by TSTF-542. Therefore, the TSTF-541 allowance is added to SR 3.5.2.6.
2.2.4.4 The RBS Technical Specifications contain a Surveillance Frequency Control Program. Therefore, the Frequency for the affected SRs is "In accordance with the Surveillance Frequency Control Program." This has no effect on the applicability of the proposed change.
2.2.5 Waterford-3 2.2.5.1 The current Waterford-3 TS format, numbering, and terminology is consistent with the NUREG-0212 Standard Technical Specifications (STS). The NUREG-0212 STS numbering for surveillance requirements differs from the numbering in NUREG-1432, "Standard Technical Specifications Combustion Engineering Plants," (i.e., the Improved STS which were used to develop TSTF-541). Specifically, NUREG-1432 TS 3.6.8, "Shield Building Exhaust Air Cleanup System (SBEACS) (Dual)," is Waterford-3 TS 3.6.6.1 and titled "Shield Building Ventilation System." The Waterford-3 TS SRs affected by the proposed changes are SR 4.6.6.1.d.2 and SR 4.6.6.1.d.3.
NUREG-1432 TS 3.7.10, "Essential Chilled Water (ECW)," is Waterford-3 TS 3.7.12 "Essential Services Chilled Water System." Waterford-3 SRs do not require verification of automatic dampers or valves repositioning on an actuation signal. Therefore, no changes are required.
NUREG-1432 TS 3.7.11, "Control Room Emergency Air Cleanup System (CREACS)," is Waterford-3 TS 3.7.6.1 and titled "Control Room Emergency Air Filtration System." The current Waterford-3 TS SRs that would be affected by this TSTF, already contain "except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position" Therefore, no changes are required.
NUREG-1432 TS 3.7.13, "Emergency Core Cooling System (ECCS) Pump Room Exhaust Air Cleanup System (PREACS)," and TS 3.7.15, "Penetration Room Exhaust Air Cleanup System (PREACS)," are consolidated into Waterford-3 TS 3.7.7 and titled "Controlled Ventilation Area System." The Waterford-3 TS SRs affected by the proposed changes are SR 4.7.7.d.2 and SR 4.7.7.d.3.
These variations are administrative, consistent with the current Waterford-3 TS, as well as the underlying NUREG-0212 basis for the current Waterford-3 TS and does not affect the applicability of TSTF-541 to the Waterford-3 TS.
2.2.5.2 The Waterford-3 TS contain requirements that differ from the Standard Technical Specifications on which TSTF-541 was based, but these differences do not affect the applicability of the TSTF-541 justification.
CNRO2021-00019 Enclosure Page 12 of 16 NUREG-1432 TS 3.6.8 is titled "Shield Building Exhaust Air Cleanup System (SBEACS) (Dual)," which for Waterford-3 is TS 3.6.6.1 "Shield Building Ventilation System." The affected SRs from the TSTF-541 read:
o SR 3.6.8.3 "Verify each SBEACS train actuates on an actual or simulated actuation signal,"
o SR 3.6.8.4 "Verify each SBEACS filter bypass damper can be opened."
This is Waterford-3 TS 3.6.6.1 "Shield Building Ventilation System."
SR 4.6.6.1.d.2 and SR 4.6.6.1.d.3 are affected and read:
- d. In accordance with the Surveillance Frequency Control Program by:
o SR 4.6.6.1.d.2 "Verifying that the system starts on a safety injection actuation test signal.,"
o SR 4.6.6.1.d.3 "Verifying that the filter cooling bypass valves can be manually cycled."
The SR 4.6.6.1.d.2 variance in wording from NUREG-1432 SR 3.6.8.3 does not alter the intent of the TSTF-541 change.
With respect to SR 4.6.6.1.d.3, it is proposed to replace the words "manually cycled" with the word "opened" to be consistent with NUREG-1432 SR 3.6.8.4. The filter cooling bypass valves of the Shield Building Ventilation System remain open to assure the non-operating filter train has adequate airflow for filter cooling while the in-service filter train is operating. The filter trains themselves cannot be bypassed. The filter cooling bypass valves are butterfly valves, not dampers. Therefore, the SR 4.6.6.1.d.3 variance in wording from NUREG-1432 SR 3.6.8.4 regarding the filter cooling bypass valves is necessary to accurately describe the testing requirement.
NUREG-1432 TS 3.7.13 titled "Emergency Core Cooling System (ECCS)
Pump Room Exhaust Air Cleanup System (PREACS)" and TS 3.7.15 titled "Penetration Room Exhaust Air Cleanup System (PREACS)" and combined into one TS at Waterford-3, TS 3.7.7 and titled "Controlled Ventilation Area System."
Waterford-3 Controlled Ventilation Area System performs the accident mitigation functions of high efficiency particulate filtration and iodine adsorption of the air exhausted from the ECCS pump rooms and the containment penetration area, and Waterford-3 TS 3.7.7 provides the operability requirements. As such, the TSTF-541 exceptions identified for NUREG-1432 TS SRs 3.7.13.3 and 3.7.13.5 and TS SRs 3.7.15.3 and 3.7.15.5 can be applied to Waterford-3 TS SRs 4.7.7.d.2 and 4.7.7.d.3.
CNRO2021-00019 Enclosure Page 13 of 16 The NUREG-1432 SRs read:
FREQUENCY = "In accordance with the Surveillance Frequency Control Program" o SR 3.7.13.3 "Verify each ECCS PREACS train actuates on an actual or simulated actuation signal" o SR 3.7.13.5 "Verify each ECCS PREACS filter bypass damper can be opened" o SR 3.7.15.3 "Verify each PREACS train actuates on an actual or simulated actuation signal" o SR 3.7.15.5 "Verify each PREACS filter bypass damper can be opened" The Waterford-3 SRs read:
- d. In accordance with the Surveillance Frequency Control Program by:
o SR 4.7.7.d.2 "Verifying that the system starts on a Safety Injection Actuation Test Signal and achieves and maintains a negative pressure of 0.25 inch water gauge within 45 seconds."
o SR 4.7.7.d.3 "Verifying that the filter cooling bypass valves can be manually cycled."
The Waterford-3 SR 4.7.7.d.2 variance in wording does not alter the intent of the TSTF-541 change and preserves the current licensing basis.
To maintain consistency with NUREG-1432 SRs 3.7.13.5 and 3.7.15.5, in SR 4.7.7.d.3, the words "manually cycled" will be replaced with the word "opened." The filter cooling bypass valves of the Controlled Ventilation Area System remain open to assure the non-operating filter train has adequate airflow for filter cooling while the in-service filter train is operating.
The filter trains themselves cannot be bypassed. The filter cooling bypass valves are butterfly valves, not dampers. Therefore, the variance in Waterford-3 TS SR 4.7.7.d.3 regarding the filter cooling bypass valves is necessary to accurately describe the testing requirement.
2.2.5.3 The Waterford-3 Technical Specifications contain a Surveillance Frequency Control Program. Therefore, the Frequency for the affected SRs is "In accordance with the Surveillance Frequency Control Program." This has no effect on the applicability of the proposed change.
2.2.5.4 Editorial changes in font, font size, and formatting were made to Waterford-3 TS pages affected by this License Amendment Request.
CNRO2021-00019 Enclosure Page 14 of 16 2.3 Licensee Verifications Entergy confirms that existing administrative processes, such as the Corrective Action Program, Operability Determination process, the maintenance, design control, configuration control, and operating procedures, etc., will be used to assess the operability of the system or of any supported systems when utilizing the SR allowances, which includes consideration of whether movement of the affected valves or dampers following an event is assumed in the safety analysis.
3.0 REGULATORY EVALUATION
3.1 No Significant Hazards Consideration Analysis Entergy Operations, Inc. (Entergy) requests adoption of Technical Specification Task Force (TSTF) TSTF-541, "Add Exceptions to Surveillance Requirements for Valves and Dampers Locked in the Actuated Position," which is an approved change to the Standard Technical Specifications (STS), into the Arkansas Nuclear One, Unit 1 (ANO-1), Arkansas Nuclear One, Unit 2 (ANO-2), Grand Gulf Nuclear Station Unit 1 (GGNS), River Bend Station, Unit 1 (RBS), and Waterford Steam Electric Station, Unit 3 (Waterford-3) Technical Specifications (TS). The proposed amendment modifies the TS Surveillance Requirements (SRs) by adding exceptions to consider the SR met when automatic valves or dampers are locked, sealed, or otherwise secured in the actuated position, in order to consider the SR met. Securing the automatic valve or damper in the actuated position may affect the operability of the system or of any supported systems.
The associated Limiting Condition for Operation (LCO) is met if the subject structure, system or component (SSC) remains operable (i.e., capable of performing its specified safety function).
Entergy 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 change involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed change revises SRs by adding 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 lack 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 portions of certain SRs, but the SSC must still be capable of performing the safety functions assumed in the accident analysis. Otherwise, the SSC is inoperable, and the associated TS Actions are followed. As a result, the SSCs continue to perform their mitigating functions and the consequences of any accident previously evaluated are not affected.
CNRO2021-00019 Enclosure Page 15 of 16 Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2.
Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No The proposed change revises SRs by adding 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 will not change the design function or operability requirements of the affected SSCs. The SSC must still be capable of performing the safety functions assumed in the accident analysis or the SSC is inoperable, and the associated TS Actions are followed. The proposed change does not create any credible new failure mechanisms, malfunctions, or accident initiators not considered in the design and licensing bases.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3.
Does the proposed change involve a significant reduction in a margin of safety?
Response: No The proposed change revises SRs by adding 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, Entergy 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.
3.2 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.
4.0 ENVIRONMENTAL CONSIDERATION
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 Part 20, or would change an
CNRO2021-00019 Enclosure Page 16 of 16 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.

F.1 If both CREVS trains are inoperable in MODE 1, 2, 3, or 4 for reasons other than an inoperable CRE boundary (i.e., Condition B), the CREVS may not be capable of performing the intended function and a loss of safety function has occurred. Therefore, LCO 3.0.3 must be entered immediately.
SURVEILLANCE REQUIREMENTS SR 3.7.9.1 Standby systems should be checked periodically to ensure that they function properly. As the environment and normal operating conditions on this system are not severe, testing each train on a monthly basis adequately checks this system by initiating flow through the HEPA filters and charcoal adsorbers. The CREVS is designed without heaters and need only be operated for 15 minutes to demonstrate the function of the system. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.
SR 3.7.9.2 This SR verifies that the required CREVS testing is performed in accordance with the Ventilation Filter Testing Program (VFTP). The VFTP includes testing HEPA filter performance, charcoal adsorber efficiency, minimum system flow rate, and the physical properties of the activated charcoal. Specific test Frequencies and additional information are discussed in detail in the VFTP.
SR 3.7.9.3 This SR verifies that the CREVS automatically isolates the CRE within 10 seconds and switches into a recirculation mode of operation with flow through the HEPA filters and charcoal adsorber banks on an actual or simulated actuation signal. The SR excludes automatic valves that are locked, sealed, or otherwise secured in the actuated position. The SR does not apply to valves that are locked, sealed, or otherwise secured in the actuated position since the affected valves were verified to be in the actuated position prior to being locked, sealed, or otherwise secured.
Placing an automatic valve in a locked, sealed, or otherwise secured position requires an assessment of the operability of the system or any supported systems, including whether it is necessary for the valve to be repositioned to the non-actuated position to support the accident analysis. Restoration of an automatic valve to the non-actuated position requires verification that the SR has been met within its required Frequency. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

SR 3.7.9.4 (continued)
This SR verifies the OPERABILITY of the CRE boundary by testing for unfiltered air inleakage past the CRE boundary and into the CRE. The details of the testing are specified in the Control Room Envelope Habitability Program.
The CRE is considered habitable when the radiological dose to CRE occupants calculated in the licensing basis analyses of DBA consequences is no more than 5 rem TEDE and the CRE occupants are protected from hazardous chemicals and smoke. This SR verifies that the unfiltered air inleakage into the CRE is no greater than the flow rate assumed in the licensing basis analyses of DBA consequences. When unfiltered air inleakage is greater than the assumed flow rate, Condition B must be entered. Required Action B.3 allows time to restore the CRE boundary to OPERABLE status provided mitigating actions can ensure that the CRE remains within the licensing basis habitability limits for the occupants following an accident.
SR 3.7.9.4 (continued)
Compensatory measures are discussed in Regulatory Guide 1.196, Section C.2.7.3, (Ref. 3) which endorses, with exceptions, NEI 99-03, Section 8.4 and Appendix F (Ref. 4). These compensatory measures may also be used as mitigating actions as required by Required Action B.2. Temporary analytical methods may also be used as compensatory measures to restore OPERABILITY (Ref. 5). Options for restoring the CRE boundary to OPERABLE status include changing the licensing basis DBA consequence analysis, repairing the CRE boundary, or a combination of these actions. Depending upon the nature of the problem and the corrective action, a full scope inleakage test may not be necessary to establish that the CRE boundary has been restored to OPERABLE status.

B.1 (continued)
Preplanned measures should be available to address these concerns for intentional and unintentional entry into the Condition. The 24-hour Completion Time is reasonable based on the low probability of a DBA occurring during this time period, and the use of compensatory measures. The 24-hour Completion Time is a typically reasonable time to diagnose, plan and possible repair, and test most problems with the PRVS negative pressure boundary.
C.1 and C.2 If the Required Action and the associated Completion Time are not met, or with both PRVS trains inoperable, the unit must be placed in a MODE in which the LCO does not apply. To achieve this status, the unit must be placed in at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging unit systems.
SURVEILLANCE REQUIREMENTS SR 3.7.11.1 Standby systems should be checked periodically to ensure that they function properly.

The pump flow rates are verified with a pump differential pressure that is sufficient to overcome 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. These values may be established during pre-operational testing. The Frequency for this Surveillance is in accordance with the Inservice Testing Program requirements.
SR 3.5.1.5 The ECCS subsystems are required to actuate automatically to perform their design functions. This Surveillance test verifies that, with a required system initiation signal (actual or simulated), the automatic initiation logic of HPCS, 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 in the flow path to their required positions. This test may be performed by means of any series of sequential, overlapping, or total system steps so that the entire system is tested. This Surveillance also ensures that the HPCS 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 SR excludes automatic valves that are locked, sealed, or otherwise secured in the actuated position. The SR does not apply to valves that are locked, sealed, or otherwise secured in the actuated position since the affected valves were verified to be in the actuated position prior to being locked, sealed, or otherwise secured.
Placing an automatic valve in a locked, sealed, or otherwise secured position requires an assessment of the operability of the system or any supported systems, including whether it is necessary for the valve to be repositioned to the non-actuated position to support the accident analysis.
Restoration of an automatic valve to the non-actuated position requires verification that the SR has been met within its required Frequency. The LOGIC SYSTEM FUNCTIONAL TEST performed in LCO 3.3.5.1, "Emergency Core Cooling System (ECCS)
Instrumentation," overlaps this Surveillance to provide complete testing of the assumed safety function.
The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

REQUIREMENTS This SR is modified by a Note that excludes vessel injection/spray during the Surveillance. Since all active components are testable and full flow can be demonstrated by recirculation through the test line, coolant injection into the RPV is not required during the Surveillance.
SR 3.5.1.6 The ADS designated S/RVs are required to actuate automatically upon receipt of specific initiation signals. A system functional test is performed to demonstrate that the mechanical portions of the ADS function (i.e.,
solenoids) operate as designed when initiated either by an actual or simulated initiation signal, causing proper actuation of all the required components. SR 3.5.1.7 and the LOGIC SYSTEM FUNCTIONAL TEST performed in LCO 3.3.5.1 overlap this Surveillance to provide complete testing of the assumed safety function.
The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.
This SR is modified by a Note that excludes valve actuation. This prevents an RPV pressure blowdown.
SR 3.5.1.7 A manual actuation of each required ADS valve (those valves removed and replaced to satisfy SR 3.4.4.1) is performed to verify that the valve is functioning properly. This SR can be demonstrated by one of two methods. If performed by method 1), plant startup is allowed prior to performing this test because valve OPERABILITY and the setpoints for overpressure protection are verified, per ASME requirements (Ref. 16) prior to valve installation. Therefore, this SR is modified by a note that states the surveillance is not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reactor steam pressure and flow are adequate to perform the test.

SR 3.5.2.5 Verifying that the required ECCS injection/spray subsystem can be manually aligned, and the pump started and operate for at least 10 minutes demonstrates that the subsystem is available to mitigate a draining event. This SR is modified by two Notes. Note 1 states that testing the ECCS injection/spray subsystem may be done through the test return line to avoid overfilling the refueling cavity. Note 2 states that credit for meeting the SR may be taken for normal system operation that satisfies the SR, such as using the RHR mode of LPCI for 10 minutes.
The minimum operating time of 10 minutes was based on engineering judgment. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.
SR 3.5.2.6 Verifying that each valve credited for automatically isolating a penetration flow path actuates to the isolation position on an actual or simulated RPV water level isolation signal is required to prevent RPV water inventory from dropping below the TAF should an unexpected draining event occur.
The SR excludes automatic valves that are locked, sealed, or otherwise secured in the actuated position. The SR does not apply to valves that are locked, sealed, or otherwise secured in the actuated position since the affected valves were verified to be in the actuated position prior to being locked, sealed, or otherwise secured. Placing an automatic valve in a locked, sealed, or otherwise secured position requires an assessment of the operability of the system or any supported systems, including whether it is necessary for the valve to be repositioned to the non-actuated position to support the accident analysis. Restoration of an automatic valve to the non-actuated position requires verification that the SR has been met within its required Frequency. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.
SR 3.5.2.7 This Surveillance verifies that a required LPCI subsystem, LPCS System, or HPCS System can be manually aligned and started from the control room, including any necessary valve alignment, instrumentation, or controls, to transfer water from the suppression pool or CST to the RPV.
The Surveillance Frequency is controlled under the Surveillance Frequency Control Program This SR is modified by a Note that excludes vessel injection/spray during the Surveillance. Since all active components are testable and full flow can be demonstrated by recirculation through the test line, coolant injection into the RPV is not required during the Surveillance.

RCIC System B 3.5.3 RIVER BEND B 3.5-24 Amendment No. 196 BASES SURVEILLANCE SR 3.5.3.3 and SR 3.5.3.4 REQUIREMENTS (continued)
The RCIC pump flow rates ensure that the system can maintain reactor coolant inventory during pressurized conditions with the RPV isolated.
The flow tests for the RCIC System are performed at two different pressure ranges such that system capability to provide rated flow is tested both at the higher and lower operating ranges of the system.
Additionally, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the RCIC System diverts steam flow. Since the required reactor steam pressure must be available to perform SR 3.5.3.3 and SR 3.5.3.4, 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 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 test 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 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the reactor steam pressure and flow are adequate to perform the test.

SR 3.7.2.4 This SR verifies the OPERABILITY of the CRE boundary by testing for unfiltered air inleakage past the CRE boundary and into the CRE. The details of the testing are specified in the Control Room Envelope Habitability Program.
The CRE is considered habitable when the radiological dose to CRE occupants calculated in the licensing basis analyses of DBA consequences is no more than 5 rem TEDE and the CRE occupants are protected from hazardous chemicals and smoke. This SR verifies that the unfiltered air inleakage into the CRE is no greater than the flow rate assumed in the licensing basis analyses of DBA consequences. When unfiltered air inleakage is greater than the assumed flow rate, Condition B must be entered. Required Action B.3 allows time to restore the CRE boundary to OPERABLE status provided mitigating actions can ensure that the CRE remains within the licensing basis habitability limits for the occupants following an accident. Compensatory measures are discussed in Regulatory Guide 1.196, Section C.2.7.3, (Ref. 7) which endorses, with exceptions, NEI 99-03, Section 8.4 and Appendix F (Ref. 8). These
RIVER BEND B 3.7-15 Amendment No. 196, (continued) compensatory measures may also be used as mitigating actions as required by Required Action B.2. Temporary analytical methods may also be used as compensatory measures to restore OPERABILITY (Ref. 9).
Options for restoring the CRE boundary to OPERABLE status include changing the licensing basis DBA consequence analysis, repairing the CRE boundary, or a combination of these actions. Depending upon the nature of the problem and the corrective action, a full scope inleakage test may not be necessary to establish that the CRE boundary has been restored to OPERABLE status.
