MEMORANDUM FOR: A. Schwencer, Chief, Licensing Branch No. 2, DL

, FROM: D. Houston, Project Manager, Licensing Branch No. 2, DL

SUBJECT:

SU M ARY OF JULY 14, 1982 MEETING WITH MP&L ABOUT l HUMPHREY'S MARK III CONTAINMENT CONCERNS I

l On July 14, 1982, a meeting was held in Bethesda, Maryland to discuss -

Mr. John Humphrey's concerns about the Grand Gulf Mark III containment system. These concerns were given in a transcript of a previous meeting held on May 27, 1982, and reported in our meeting sumary dated June 16,

. 1982. This meeting (July 14) was attended by representatives of NRC, MP&L, GE A-Es and consultants (See ' Attachment 1).

4

) The purpose of this meeting was to review MP&L's action plan and schedule i

for resolution of these containment concerns. The details of the action plan and schedule are given in the meeting handout (Attachment 2). A total of 46 issues were listed: 16 to be analyzed and submitted for review by August 19, 1982, an additional 22 by October 1,1982, and the

remaining 8 by November 1,1982. In the August 19 submittal, MP&L would

also provide a justification for full power operation for all items (30)

, not analyzed. MP&L discussed the benefits of postponing the August 19 l submittal. From a licensing position with a tentative Comission briefing

scheduled for early in September, we could not grant any slippage in the l August submittal date. The staff did agree to review the list of 46 issues

and prioritize them so that the August submittal would be more effective.

l l The staff discussed the NRC interest in a Peer Review Group to evaluate these conce.ms and the approach to resolution. MP&L was asked to pursue this matter with the other Mark III owners and attempt to establish such a group.

The forthcoming meetings in San Jose, Qilifornia were discussed. On July 22. GE and the BWR Owne r's Group will meet with Mr. Humptrey. NRC

, was-invited to attend as an observer and the Containment Systems Branch i

indicated they would send a representative. On July 29 and 30, the ACRS l subcommittee on Fluid Dynamics will meet to discuss these same containment concerns. A tentative agenda is . attached (Attachment 3). A detailed agenda for Item VII.of the ACRS meeting is given in the last three pages of the MP&L handout (Attachment 2).
