Background===
By letter dated December 11, 2020 (Reference 1), as supplemented by letter dated February 18, 2021 (Reference 2), Exelon Generation Company, LLC (Exelon) submitted a license amendment request for James A. FitzPatrick Nuclear Power Plant (FitzPatrick). The proposed amendment request would revise Technical Specification (TS) Limited Condition for Operation (LCO) 3.5.1 ECCS - Operating Surveillance Requirement (SR) 3.5.1.6 from Once each startup prior to exceeding 25% RTP, as modified by a Note stating Not required to be performed if performed within the previous 31 days to 24 months.
The NRC made requests for additional information (RAI) in an email dated July 1, 2021 (Reference 3). The additional information requests and the Exelon responses are provided below.
RAI-1
The LAR proposes to change SR 3.5.1.6. The proposed change eliminates the notation of Not required to be performed if performed within the previous 31 days and changes the specified frequency from Once each startup prior to exceeding 25% RTP to 24 months.
Please explain the reason to modify SR 3.5.1.6 to require a frequency of 24-month instead of In accordance with the INSERVICE TESTING PROGRAM, which is specified in TSTF-545, TS Inservice Testing [IST] Program & Clarify SR Usage Rule Application to Section 5.5 Testing.
Response to RAI-1 The frequency of this SR was not In accordance with the Inservice Testing Program.
TSTF-545 affected SRs with a frequency that was In accordance with the Inservice Testing Program. As such, the frequency of SR 3.5.1.6 is not within the scope of the SRs affected by TSTF-545.
The proposed frequency of 24 months is, however, consistent with the license amendment submitted by Detroit Edison Fermi 2 on March 23, 1999 and approved by the NRC on May 25, 1999 (ML020720643) which allowed the licensee to revise the frequency from once every startup (which included start-ups from mid-cycle outages) to a frequency consistent with that licensees refueling cycle thus eliminating the unnecessary cycling during a startup from mid-cycle outages.
Further, maintaining the FitzPatrick SR 3.5.6.1 frequency independent of the Inservice Testing program is consistent with the current ITS SR 3.5.6.1 frequency which is also independent of the Inservice Testing Program.
Request for Additional Information And Detailed Response Page 2 of 4
RAI-2
The proposed FitzPatrick LAR text of the SURVEILLANCE statement in SR 3.5.1.6 remains the same as Verify each recirculation pump discharge valve cycles through one complete cycle of full travel or is de-energized in the closed position. The NRC staff is concerned with potential unintended consequences of this proposed change as written. The Bases for SR 3.5.1.6 states, in part, that Cycling the recirculation pump discharge valves through one complete cycle of full travel demonstrates that the valves are mechanically OPERABLE and will close when required.
The proposed change does not appear to provide reasonable assurance that periodic cycling of the valve will be completed due to the portion of the SR which would state or is de-energized in the closed position. Satisfaction of the current proposed wording could be a simple turn of the electric breaker to the off position and then back to the on position when the valve is in the closed position.
Please explain why the portion of the SR which would state or is de-energized in the closed position is needed because the valves will be required to be stroked in accordance with the IST Program. In addition, please clarify the mismatch between the requirements of SR 3.5.1.6 and its Bases.
Response to RAI-2 The proposed change does not change the manner in which the valves are tested as required by the FitzPatrick IST Program. The change only alters the frequency at which the valves are required to cycled as required by SR 3.5.1.6 from an event based frequency to a time based frequency. IST and MOV program requirements are not superseded or bypassed by this change.
As stated in the Exelon letter dated February 18, 2021 Supplement to Application to Revise Surveillance Requirement (SR) 3.5.1.6 (Reference 2) the valves will continue to be tested in the same manner that they have been tested under the current frequency. The only difference being the elimination of the wear and tear of the valves by performing unnecessary mid-cycle testing and potentially delaying the restart of the unit which is contrary to the guidance in ISTC-3521(g) which states: valve exercising during cold shutdowns shall commence within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of achieving cold shutdown and continue until all testing is complete or the plant is ready to return to operation at power.
The Technical Specifications (TS) Bases for SR 3.5.1.6 states that the valve safety function is to close upon an automatic initiation of the LPCI subsystem. Cycling the valve through one complete cycle ensures that the valve is not mechanically bound and able to close when required. The statement, or is de-energized in the closed position exempts from the SR valves which are inoperable and are required to be de-energized in the closed position. The intent of this statement is to allow an inoperable isolation valve to remain secured in the actuated position by de-energizing the associated breaker thus meeting the intent, as described in the Bases, of the SR. It is understood that prior to restoring an inoperable valve to service, all SRs shall be completed including SR 3.5.1.6.
FitzPatrick Surveillance Testing is scheduled and executed as informed by both the TS SR as well as the TS Bases for that SR and therefore, in practice, there is no mismatch between the requirements of SR 3.5.1.6 and its Bases.
Request for Additional Information And Detailed Response Page 3 of 4 During the conversion from the FitzPatrick custom TS (CTS) to ITS (Amendment 274),
FitzPatrick stated that in order to meet TS 3.5.1 requirements, inoperable isolation valves would not only to be closed but de-energized. It was further clarified that requiring the inoperable reactor water recirculation pump discharge valve to be de-energized in the closed position represents an additional restriction on plant operations. The following excerpt is from Table M of the NRC SER dated July 3, 2002.
M10 CTS 3.5.A.5 requires all recirculation pump discharge valves to be Operable prior to reactor startup (or closed if permitted elsewhere in these specifications). ITS 3.5.1 and associated SR 3.5.1.6 also require all recirculation pump discharge valves to be Operable. However, if this requirement cannot be met, then ITS SR 3.5.1.6 allows the associated recirculation pump discharge valve to be de-energized in the closed position.
Requiring the inoperable recirculation pump discharge valve to also be de-energized in the closed position represents an additional restriction on plant operation. This change is necessary to ensure the flow path for the associated LPCI subsystem.
RAI-3
The proposed change references a precedent relating to a request made by the licensee of the Fermi 2 nuclear power plant in 1999. The Fermi 2 licensee requested to change its SR 4.4.1.1.1 to remove the notation that the surveillance is only required if it has not been performed within the last 31 days, and then to require that each pump discharge valve is OPERABLE by cycling each valve through at least one complete cycle of full travel at least once per 18 months. The request for the Fermi 2 nuclear power plant does not appear to be the same as the request for the FitzPatrick nuclear power plant. The NRC staff is unclear regarding the basis for referencing the Fermi 2 request in the FitzPatrick LAR.
Please clarify the basis for referencing the Fermi 2 request in the FitzPatrick LAR.
Response to RAI-3 Exelon believes that the reference to the Fermi 2 license amendment is directly applicable to this submittal.
As stated in response to RAI-1, Fermi submitted a license amendment on March 23, 1999 which proposed to modify Technical Specifications (TS) 4.4.1.1.1 (the equivalent surveillance as FitzPatricks SR 3.5.1.6). The Fermi 2 proposed change was identical to the proposed FitzPatrick change with the only difference being the number of months in each licensees operating cycle (18-months vs 24-months). By replacing the once every startup requirement with a fixed frequency, the footnote stating if not performed within the previous 31 days became unnecessary. This is re-stated at the top of page 2 of the NRC SER dated May 25, 1999. The statement reads: The licensee proposed to revise the frequency of SR 4.4.1.1.1 to once per 18 months. With this change the
- footnote would be unnecessary, and it would be deleted from the SR Request for Additional Information And Detailed Response Page 4 of 4 This precedent demonstrates an equivalent approval in which the licensee received NRC approval to move this requirement from event based to time based with the time between valve cycles being determined by the length of the operating cycle. Effectively, both applications eliminate the requirement to cycle the valves during mid-cycle outages thus minimizing unnecessary wear and tear on the valve and operator.
RAI-4
The LAR provides a brief list of prior testing of motor-operated valves (MOVs) 053A and 053B, which appears to be stroke-time testing. The LAR also mentions that these valves are periodically tested under the MOV testing program established in accordance with Generic Letter 96-05, Periodic Verification of Design-Basis Capability of Safety-Related Motor-Operated Valves, dated September 18, 1996.
Please discuss the past historical performance of these valves with respect to how Fitzpatrick is meeting the requirements of 10 CFR 50.55a(b)(3)(ii). Historical performance should include the type of testing performed and any maintenance or modifications that may have been completed.
RESPONSE TO RAI-4.
The Reactor Water Recirculation pump discharge isolation valves, 02-2MOV-53A and 02-2MOV-53B, and associated operators are in scope of the FitzPatrick MOV Program as established in accordance with Generic Letter 96-05, Periodic Verification of Design-Basis Capability of Safety-Related Motor-Operated Valves, dated September 18, 1996. Diagnostic testing of these valves, as required by the MOV program is currently scheduled for performance on a four year interval beginning in September 2022.
These valves have a LOW Risk Rank and based on the most recent performances in 2020, both valves are characterized as having HIGH Margin. As such diagnostic testing is bound by the program MAXIMUM interval of 10 years. A discussion of the diagnostic testing results from the past three performances is provided in Attachment 2.
Historically, valve diagnostic testing was performed consistent with the MOV program requirement of every six (6) years. A more detailed maintenance history for the subject MOVs is provided in Attachments 3(a), 3(b), 3(c) and 3(d). The Program required maximum interval is 10 years. Neither the MOV program required interval of ten (10) years, nor the current scheduled interval of four (4) years will be affected by revising the SR from an event based frequency to a time based frequency. In the event that future diagnostic testing indicates the need for a shorter interval for MOV program required testing, the SR frequency of 24 months will continue to support a reduced interval.
The interval required for diagnostic testing is established based on risk and diagnostic test margin. The limits established for stroke time testing are in accordance with the design basis and will not be changed as part of this request. All MOV and IST Program requirements remain in place with this change as do all commitments made regarding these valves.
