Dear Mr. Withers:

SUBJECT:
VALVE M0-8812 TEST PARAMETERS f
Enclosed is the staff's Safety Evaluation addressing your request to change the test parameters used in leak testing valve M0-8812.
Based on the more accurate measurements that will be obtained by using water as a test medium, the staff concludes that changing the test medium for valve M0-8812 from gas to water is acceptable.
l Based'on Portland General Electric's analysis and the staff's review of the analysis, we conclude that 33.6 psi differential pressure across the valve is
.a suitably conservative test pressure for valve M0-8812 and is therefore t
acceptable.
Sincerely,
/s/
Edward J. Butcher, Acting Chief l
Operating Reactors Branch #3 Division of Licensing
