SUBJECT:
PERRY NUCLEAR POWER PLANT, UNIT 1 - CORRECTION OF SAFETY EVALUATION FOR AMENDMENT DATED OCTOBER 27, 2006 (TAC NO.
Dear Mr. Pearce:
On October 27, 2006, the Nuclear Regulatory Commission (NRC) issued Amendment No. 139, to Facility Operating License No. NPF-58, for the Perry Nuclear Power Plant, Unit 1. The amendment was in response to your application dated November 15, 2005.
The amendment modified the technical specifications to clarify the wording of emergency closed cooling water (ECCW) Surveillance Requirement (SR) 3.7.10.2. This letter transmits a correction to the NRC staffs safety evaluation (SE) associated with the aforementioned amendment number. The correction deletes an incorrect clause describing how the physical boundary of the safety-related ECCW system subsystems have been made passive.
The NRC staff has resolved this error by correcting the appropriate section in the SE, which did not impact the conclusions of the NRC staffs original SE. The corrected SE page is included as an enclosure to this letter and replaces the associated page in the original NRC staffs SE.
If there are any questions concerning this matter, please contact Tom Wengert at (301) 415-4037.
Sincerely,
/RA/

PERRY NUCLEAR POWER PLANT, UNIT 1 -
CORRECTION TO OCTOBER 27, 2006, SAFETY EVALUATION PAGE 2 ENCLOSURE
3.0 TECHNICAL EVALUATION
The NRC staff reviewed the proposed change for compliance with 10 CFR 50.36 and for consistency with the precedent established in NUREG-1434, Standard Technical Specifications [STSs] General Electric Plants, BWR/6. The change would make the SR 3.7.10.2 wording consistent with the more standard wording of the system actuation SRs in TS 3.7.1, [Standby Service Water (SSW)] System and [Ultimate Heat Sink (UHS)];
TS 3.7.2, High Pressure Core Spray (HPCS) Service Water System (SWS); and TS 3.7.3,
[Control Room Fresh Air (CRFA)] System, of NUREG-1434. In the licensees amendment request dated November 15, 2005, the licensee noted that an ECCW specification is not included in NUREG-1434 because the ECCW system is a Perry-specific plant design.
The current wording of SR 3.7.10.2 requires that automatic valves in ECCW actuate on an actuation signal. However, the TS Bases for the SR identify that more than just valves are tested. The TS Bases state, This Surveillance also verifies the automatic start capability of the ECCW pump in each subsystem. During development of the Perry improved STSs, no direct template existed for the wording of SR 3.7.10.2, since NUREG-1434 did not include an ECCW specification. Therefore, wording similar to the original Perry TS SR was incorporated. The non-standard wording focused on valve actuation, since the original ECCW system design required several valves to close after an accident to isolate the safety-related ECCW system from a non-safety cooling water system. The overall system actuation was only addressed in the TS Bases. Since that time, the physical boundary for the safety-related ECCW subsystems has been made passive. It is therefore appropriate to revise the SR wording to reflect actuation of the total system, consistent with the standard wording of SRs in TS 3.7.1, 3.7.2, and 3.7.3 of NUREG-1434. This is accomplished by revising SR 3.7.10.2 to read, Verify each ECCW subsystem actuates on an actual or simulated initiation signal.
The licensees amendment request rewords SR 3.7.10.2 to more clearly state that the actuation capability of the entire ECCW system must continue to be tested. This change also ensures consistency with the standard wording in SRs for TSs 3.7.1, 3.7.2, and 3.7.3 as described in NUREG-1434 and for verifying the overall system actuation as described in the Perry TS Bases. The NRC staff determined that this is an administrative clarification and the rewording of SR 3.7.10.2 does not change the technical content of the specification.
The NRC staffs position, in general, is that there are two classes of TS changes: (1) changes needed to reflect contents of the design basis (as mentioned above, TSs are derived from the design basis), and (2) voluntary changes to take advantage of the evolution in policy and guidance as to the required content and preferred format of TSs over time.
The NRC staff concludes that this amendment involves the second class of changes; namely, administrative changes that reflect the current configuration of the plant and consistency with the TS Bases. Furthermore, the licensees proposed changes are acceptable since they conform to the standard wording in NUREG-1434 and continue to meet the requirements of 10 CFR 50.36, and 10 CFR Part 50, Appendix A, Criterion 44.
