Subject:
Docket _No. 50-206 Generic Letter 87-06 Response San Onofre Nuclear Generating Station Unit 1
.The referenced Generic Letter 87-06 dated March 13, 1987 requested SCE to provide information pertaining to leak-tight integrity of all Reactor Coolant System (RCS) pressure isolation valves.
The purpose of this letter is to provide SCE's response for San Onofre Unit 1.
Accordingly, provided in an enclosure to this letter is a list of all pressure isolation valves at San Onofre Unit 1.
For each valve, the list describes the periodic tests or other measures performed to assure valve integrity, any operational limits and testing frequency.
The enclosed list does not include valves on lines 3/8" diameter or less, since makeup for line breaks of this size can be provided by the normal charging system. Additionally, manual RCS drain and vent valves'have been excluded from the list, since these valves are normally closed and are exempt from Inservice Testing (IST) Program testing per ASME Code Sr-tion XI Article IHV-1200.
Those RCS pressure isolation valves identified in the enclosed list that are not currently included in the IST program will be evaluated for inclusion.
It should be noted that all reactor coolant leakage is monitored per Technical Specification 3.1.4, Leakage, which applies to all systems connected to the RCS.
This specification requires the RCS to be monitored for evidence of leakage and limits total leakage to 1 gpm for unidentified and 6 gpm for identified provided that in the latter case an evaluation demonstrates that continued operation is safe.
