RE:
NINE MILE POINT UNIT 1 Gray file NPaulson Based on our review of tho information submitted on your docket regarding the Mark I containment reevaluation program (up to and including tho Mark I Containment Status Report dated, July 31, 1975,'ubmitted by tho Gonoral Electric Company),
we have idontified additional information that is required to continue our review.
The information required is listed in tho enclosure and pertains to tho functional operability of-piping and components when subjected to (1) pool swell loads associated with a loss-ol-coolant
- accident, and (2) loads from operation of the primary system pressure relief valves.
The items listed in the enclosure should be addressed during the Long Term Program proposed by the Mark 1 (httners Group.
Ne anticipato that further information will be required based on our review of the Short Term Program report.
Please contact us if you desire clarification of tho information required.
This request for generic information was approved by GAO under a blanket clearance number B-180225 (R0072); this clearance expires July 31, 1977.
Sincerely, Z5/
