Subject:
Byron Station Units 1 and 2 Application for Amendment to Facility Operating License NPF-37 Appendix A, Technical Specifications NRC Docket Nos. 50-454 and 50-455 Reference (a): August 15, 1986 letter frce K. A. Ainger to H. R. Denton
Dear Mr. Denton:
Reference (a) requested a license amendment to create an additional technical specification for the essential service water system. The proposed technical specification required an essential service water pump and associated valves of a shutdown unit to be available to support an operating unit.
This letter supplements reference (a) and contains two additional measures to assure the availability of the essential water system. First, Byron Station will not intentionally take one essential service water pump out of service from each unit at the same time for maintenance. Secondly, an additional technical specification is hereby proposed to require the availability.of the essential service water crosstie between Units 1 and 2 whenever either or both units are in Modes 1, 2, 3, or 4.
The additional technical specification is contained in Attachment
- 1. This' additional technical specification is being proposed for the same reason as the amendment in reference (a) was requested; that is, to address the probability and consequences of a loss of all essential service water.
As a result, our evaluation of significant hazards considerations discussed in reference (a) is applicable to this additional technical specification concerning the crosstie between units.
