SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 268 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-46 NEBRASKA PUBLIC POWER DISTRICT COOPER NUCLEAR STATION DOCKET NO. 50-298
1.0 INTRODUCTION
By application dated April 1, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20101H298), Nebraska Public Power District (the licensee) submitted a license amendment request (LAR) for Cooper Nuclear Station (Cooper). The amendment would revise technical specification (TS) actions for inoperable residual heat removal (RHR) shutdown cooling subsystems in the RHR shutdown cooling system limiting conditions for operation.
The proposed changes are based on Technical Specifications Task Force (TSTF) Traveler TSTF-566, Revision 0, Revise Actions for Inoperable RHR Shutdown Cooling Subsystems, dated January 19, 2018 (ADAMS Accession No. ML18019B187). The U.S. Nuclear Regulatory Commission (NRC, the Commission) issued a final safety evaluation approving TSTF-566, Revision 0, on February 21, 2019 (ADAMS Accession No. ML19028A287), using the consolidated line item improvement process.
The licensee has proposed variations from the TS changes described in TSTF-566, Revision 0.
The variations are described in Section 2.2.3 and evaluated in Section 3.3 of this safety evaluation.
2.0 REGULATORY EVALUATION
2.1 Description of Residual Heat Removal Shutdown Cooling System Irradiated fuel in the shutdown reactor core generates heat during the decay of fission products and increases the temperature of the reactor coolant. This decay heat must be removed to reduce the temperature of the reactor coolant to less than or equal to 200 degrees Fahrenheit.
This decay heat is removed by the RHR shutdown cooling system in preparation for performing refueling or maintenance operations, or for keeping the reactor in the hot shutdown condition or cold shutdown condition.
Enclosure 2
The two redundant, manually controlled shutdown cooling subsystems of the RHR system provide decay heat removal. Each of the two shutdown cooling subsystems of the RHR system can provide the required decay heat removal. Each RHR shutdown cooling subsystem consists of one or two motor-driven pumps, a heat exchanger, and associated piping and valves. The RHR heat exchangers transfer heat to the service water system. Some piping and heat exchangers that are passive components may be common to both subsystems.
Cooper TS 3.4.7, Residual Heat Removal (RHR) Shutdown Cooling System - Hot Shutdown, is applicable in Mode 3, with the reactor steam dome pressure less than the shutdown cooling permissive pressure. Cooper TS 3.4.8, Residual Heat Removal (RHR) Shutdown Cooling System - Cold Shutdown, is applicable in Mode 4. They both require two operable RHR shutdown cooling subsystems and, with no recirculation pump in operation, at least one RHR shutdown cooling subsystem in operation.
2.2 Proposed Changes to the Technical Specifications The licensee proposed to revise TS actions for inoperable RHR shutdown cooling subsystems in the RHR shutdown cooling system limiting conditions for operation, consistent with TSTF-566, Revision 0.
The proposed changes would revise TSs 3.4.7 and 3.4.8 for Cooper. The proposed changes are described below.
2.2.1 Proposed Changes to Cooper TS 3.4.7 Required actions for one or two RHR shutdown cooling subsystems inoperable (Condition A) of Cooper TS 3.4.7, require the operators to initiate action to restore RHR shutdown cooling subsystem(s) to operable status (Required Action A.1) immediately, verify an alternate method of decay heat removal is available for each inoperable RHR shutdown cooling subsystem (Required Action A.2) within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, and be in Mode 4 (Required Action A.3) within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
The licensees proposed changes to Cooper TS 3.4.7 move Required Action A.1 to new Condition B (as Required Action B.1) and delete Required Action A.3. The licensee proposed to add a recurring completion time (CT) to current Required Action A.2 of once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> thereafter. The licensees proposed changes renumber current Required Action A.2 as A.1 since Required Actions A.1 and A.3 are removed from Condition A.
The licensees proposed changes add a new Condition B for when the required action and associated CT of Condition A are not met. New Condition B, Required Action B.1 would be moved from current Required Action A.1, which requires operators to initiate action to restore RHR shutdown cooling subsystems(s) to operable status immediately.
Current Condition B and its required actions would be renamed C, C.1, C.2, and C.3, respectively, since a new Condition B is added.
2.2.2 Proposed Changes to Cooper TS 3.4.8 Required actions for one or two RHR shutdown cooling subsystems inoperable (Condition A) of Cooper TS 3.4.8, require the operators to verify that an alternate method of decay heat removal
is available for each inoperable RHR shutdown cooling subsystem (Required Action A.1) within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> thereafter.
The licensees proposed changes to Cooper TS 3.4.8 would add a new Condition B for when the required action and associated CT of Condition A are not met, which has a required action (new Required Action B.1) for operators to initiate action to restore RHR shutdown cooling subsystem(s) to operable status immediately.
Current Condition B and its required actions would be renamed C, C.1, and C.2, respectively, since a new Condition B is added.
2.2.3 Variations from TSTF-566 The Cooper TSs utilize different numbering than the Standard Technical Specifications (STSs) in NUREG-1433,1 on which TSTF-566 is based. Specifically, STS 3.4.8, Residual Heat Removal (RHR) Shutdown Cooling System - Hot Shutdown is TS 3.4.7 in the Cooper TSs and STS 3.4.9, Residual Heat Removal (RHR) Shutdown Cooling System -Cold Shutdown is TS 3.4.8 in the Cooper TSs. These differences are editorial and do not affect the applicability of TSTF-566 to the proposed LAR.
2.3 Applicable Regulatory Requirement and Guidance Title 10 of the Code of Federal Regulations (10 CFR) Section 50.36(a)(1) requires each applicant for a license authorizing operation of a utilization facility to include in the application the proposed TSs.
The regulation in 10 CFR 50.36(b) states, in part:
Each license authorizing operation of a . . utilization facility . . will include technical specifications. The technical specifications will be derived from the analyses and evaluation included in the safety analysis report, and amendments thereto, submitted pursuant to [10 CFR] 50.34 [Contents of applications; technical information]. The Commission may include such additional technical specifications as the Commission finds appropriate.
The regulation in 10 CFR 50.40(a) states, in part, that the TSs shall provide reasonable assurance that the health and safety of the public will not be endangered.
The NRC staffs guidance for the review of TSs is in Chapter 16.0, Technical Specifications, of NUREG-0800, Revision 3, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR [Light-Water Reactor] Edition (SRP), dated March 2010 (ADAMS Accession No. ML100351425). As described therein, as part of the regulatory standardization effort, the NRC staff has prepared STSs for each of the LWR nuclear designs. Accordingly, the NRC staffs review includes consideration of whether the proposed changes are consistent with the applicable reference STS (i.e., the current STS), as modified by NRC-approved travelers.
1 NUREG-1433, Standard Technical Specifications, General Electric BWR [Boiling Water Reactor]/4 Plants, Volume 1, Specifications, and Volume 2, Bases, Revision 4.0, dated April 2012 (ADAMS Accession Nos. ML12104A192 and ML12104A193, respectively),
3.0 TECHNICAL EVALUATION
3.1 Proposed Changes to Cooper TS 3.4.7 In the LAR, the licensee proposed changes to revise Cooper TS 3.4.7. The NRC staffs evaluation of the licensees changes to Cooper TS 3.4.7 is described below.
3.1.1 Evaluation of Changes to Condition A The licensees proposed changes would add a recurring CT to current Required Action A.2 of once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> thereafter, to Cooper TS 3.4.7, Condition A. Current Required Action A.2 requires verification that an alternate method of decay heat removal is available for each inoperable RHR shutdown cooling subsystem within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The NRC staff finds this change is acceptable, since it requires continuous verification of alternate methods of decay heat removal every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and provides assurance of continued heat removal capability.
The licensee also proposed to delete current Required Action A.3, which requires the plant to be in Mode 4 within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when one or two RHR shutdown cooling subsystems are inoperable.
Current Required Action A.3 requires operators to reduce the reactor coolant system temperature to the point where Mode 4 is entered, due to the potentially reduced reliability of the alternate methods of decay heat removal. However, if there is no operable RHR shutdown cooling subsystem and the plant is in a period of high decay heat load, it may not be possible to reduce the reactor coolant system temperature to the Mode 4 entry condition (typically less than 200 degrees Fahrenheit) within the CT. In addition, in a typical BWR design, the RHR shutdown cooling system has a heat rejection capability many times greater than alternate methods available. Therefore, for periods in which there is high decay heat load, the BWR design does not include any system which can satisfy Required Action A.3. The NRC staff finds the deletion of current Required Action A.3 is acceptable because, at below the RHR cut in permissive pressure, the remaining required action will continue to transfer fission product decay heat and other residual heat from the reactor core at a rate such that specified acceptable fuel design limits and the design conditions of the reactor coolant pressure boundary are not exceeded.
Current Required Action A.2 would be renumbered as A.1, since Required Actions A.1 and A.3 are removed from Condition A. The NRC staff finds this change is acceptable since it provides the correct number sequence.
3.1.2 Evaluation of New Condition B The licensee proposed a new Condition B for when the required action and associated CT of Condition A is not met. New Condition Bs Required Action B.1, would be moved from current Required Action A.1 and would require operators to initiate action to restore RHR shutdown cooling subsystems(s) to operable status immediately. The NRC staff finds that relocating the required action from A.1 to new Required Action B.1 is acceptable because other ways of removing decay heat are available, such as natural circulation, the spent fuel pool cooling system, the reactor water cleanup system and an inoperable, but functional, RHR shutdown cooling subsystem.
If an alternate method cannot be established (Condition A), new Condition B requires the licensee to immediately initiate action to restore the inoperable RHR shutdown cooling subsystem(s) to operable status. The CT immediately is defined in Section 1.3 of the Cooper
TSs as, the Required Action should be pursued without delay and in a controlled manner.
New Required Action B.1 continues to apply until the inoperable RHR shutdown cooling subsystems are restored to operable status, an alternate decay heat removal method is established, or the specification is exited.
The NRC staff finds this change is acceptable because new Condition B, with its Required Action B.1, provides an appropriate terminal action for when an alternate method cannot be established within the CT. In addition, new Required Action B.1 will restore redundant decay heat removal paths and the immediate CT reflects the importance of maintaining the availability of two paths for heat removal.
3.1.3 Evaluation of Changes to Existing Condition B Current Required Action A.2 would be renumbered as A.1, since Required Actions A.1 and A.3 are deleted. Current Condition B and its required actions would be renamed C, C.1, C.2, and C.3, respectively, since new Condition B is added. The NRC staff finds these changes are acceptable since it provides the correct number sequence.
3.1.4 Conclusion of Proposed Changes to Cooper TS 3.4.7 The NRC staff concludes that the proposed changes are acceptable since the TSs continue to meet the requirements of 10 CFR 50.40(a) because they provide reasonable assurance that the health and safety of the public will not be endangered.
3.2 Proposed Changes to Cooper TS 3.4.8 In the LAR, the licensee proposed changes to revise Cooper TS 3.4.8. The NRC staffs evaluation of the licensees changes to Cooper TS 3.4.8 is described in the following sections.
3.2.1 Evaluation of New Condition B The licensee proposed a new Condition B to Cooper TS 3.4.8 for when the required action and associated CT of Condition A is not met which has a required action (new Required Action B.1) for operators to initiate action to restore RHR shutdown cooling subsystems(s) to operable status immediately.
If an alternate method cannot be established (Condition A), new Condition B requires the licensee to immediately initiate action to restore the inoperable RHR shutdown cooling subsystem(s) to operable status. The CT immediately is defined in Section 1.3 of the TSs as, the Required Action should be pursued without delay and in a controlled manner. New Required Action B.1 continues to apply until the inoperable RHR shutdown cooling subsystems are restored to operable status, an alternate decay heat removal method is established, or the specification is exited.
The NRC staff finds that this change is acceptable because new Condition B with its Required Action B.1 provide an appropriate terminal action for when an alternate method cannot be established within the CT. In addition, new Required Action B.1 will restore redundant decay heat removal paths and the immediate CT reflects the importance of maintaining the availability of two paths for heat removal.
3.2.2 Evaluation of Changes to Existing Condition B Current Condition B and its required actions would be renamed C, C.1, and C.2, respectively, since new Condition B is added. The NRC staff finds this change is acceptable because it provides the correct number sequence.
3.2.3 Conclusion of Proposed Changes to Cooper TS 3.4.8 The NRC staff concludes that the proposed changes are acceptable since the TS continues to meet the requirements of 10 CFR 50.40(a) because it provides reasonable assurance that the health and safety of the public will not be endangered.
3.3 Variations from TSTF-566 The Cooper TSs utilize different numbering than the STSs in NUREG-1433 on which TSTF-566 is based. The NRC staff determined that these differences are editorial and do not affect the applicability of TSTF-566 to the proposed LAR.
4.0 STATE CONSULTATION
In accordance with the Commissions regulations, the Nebraska State official was notified of the proposed issuance of the amendment on November 6, 2020. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes requirements with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration published in the Federal Register on June 30, 2020 (85 FR 39222), and there has been no public comment on such finding. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b),
no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
6.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that 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.
