Dear Sir:
We are forwarding the following response in regard to your letter of January 8, 1980 concerning the testing of low pressure injection system check valves to determine their status as pressure isolation valves.
Of the eight valves mentioned in your letter, four valves (8948A, B, C and D) are already periodically leak tested as part of the Trojan surveil-lance testing program. This test is performed at a refueling interval.
It utilizes existing Safety Injection System test lines to determine the differential pressure across these valves by use of pressure gages. The test procedure will be revised to include the other four valves (8818A, B, C and D) and the revised test program of the subject eight valves will be implemented at the next refueling outage for the Trojan Nuclear Plant.
Should you have any questions on this, please do not hesitate to contact me.
Sincerely,
'dh
