Dear Sir:
During discussions with your staff regarding the setpoint for the RHR relief valves in the subject Technical Specification, a question was raise:1 concerning the tolerance of the setpoint.
In response to the staff request, the low temperature overpressure protection analysis has been reviewed and a determination made that the bounding analysis limit for high pressure is 541 psig. Therefore, the setpoint value for the RHR relief valves in Seabrook Technical Specification 3.4.9.3.a should be set at 450 psig with a tolerance of A 3%.
Should you have any further questions regarding this matter, please contact Mr. Warren J. Hall at (603) 474-9574, extension 4046.
