SUBJECT:
CONVERSION TO IHPROVED TECHNICAL SPECIFICATIONS (ITS) - WASHINGTON PUBLIC POWER SUPPLY SYSTEH NUCLEAR PROJECT NO.
2 (WNP-2)
(TAC NO. H94226)
Dear Hr. Parrish:
By letter dated December 8,
- 1995, you submitted an application for an amendment to Facility Operating License No. NPF-21 for WNP-2 to convert the current Technical Specifications (TS) in Appendix A of License No.
NPF-21 to Improved Technical Specifications (ITS) consistent with NUREG-1434 "Standard Technical Specifications General Electric Plants, BWR-6" (STS).
We have reviewed the proposed changes to determine those that constitute issues outs'ide the scope of the conversion process.
We intend to address as many of these as possible as part of the conversion.
- However, several of these changes from the current TS requirements involve changes in the licensing basis which cannot be justified on the basis of the content of the improved STS and warrant particular plant-specific justification.
These issues are identified in the enclosure.
Certain of these issues may be difficult to resolve, and may unnecessarily delay timely completion of the conversion review.
These are:
Changes in the allowed outage times (AOTs) based on probabilistic risk analyses (PRA).
The review guidelines for PRA-based changes to AOTs are still being developed, and will not likely be resolved in time to incorporate these changes into the ITS.
(Items 13, 20, 26, and 28)
The extension in the surveillance interval for the airlock interlock to 24 months is a pending generic change to the STS.
If this change is resolved generically in the near term, it can be incorporated into the ITS for WNP-2.
Conversely, if the generic basis for the change is not resolved
- soon, the change will have to be addressed with plant-specific justification or revert to the current TS requirement.
(Item 21)
The proposed changes to the voltage limits, frequency values and the number of required loss-of-power channels for the emergency electrical power system may require substantial staff review.
Consequently, because of resource and scheduling constraints, these changes in the licensing basis may not be resolved in time to incorporate the changes into the ITS.
(Items 17, 18 and 41).
