1 MEMORANDUM FOR: Ashok C. Thadani, Director i PWR Project Directorate #8 Division of PWR Licensing-B FROM: Patrick M. Sears, Project Manager PWR Project Directorate #8 Division of PWR Licensing-B
SUBJECT:
MEETING ON MAY 7 & 8, 1986 CONCERNING MAINE YANKEE i SEISMIC DESIGN MARGIN PROGRAM The purpose of the meeting was to discuss Seismic Design Margin Program activities, schedules and manpower requirements. Attendees are listed in Enclosure 1. ,
I After opening remarks and introductions, Maine Yankee Atomic Power Company (MYAPCo) gave a presentation covering their plant location, plant features, and layout corporate structure and working relationship with Yankee Atomic Electric Company (YAEC). YAEC most often acts as MYAPCo's architect / engineer.
Enclosure 2 covers MYAPCo's presentation.
Next, D. Guzy of NRC/Research gave a brief history of the Seismic Design Margin Program, along with an outline of the tasks to be performed during a ll seismic margins review. Mr. Guzy also presented the organization chart for the Seismic Design Margins Review program. Mr. Guzy's presentation is included in Enclosure 3.
i R. Murray of Lawrence Livermore National Laboratory (LLNL) presented a list of items required of MYAPCo for this program. Those items are to be passed on to
. LLNL's contractors (EQE, Inc. and Energy, Inc.) for use during the review i program. Those items are included in Enclosure 4. MYAPCo agreed to provide i those items if the items were on file, that is on the condition that no
/ expenditures would be required to provide those items.
A scheduie for the project to which project participants agreed was discussed. That schedule is included as Enclosure 5. Plant walkdowns and information gathering dates were tentatively set as follows: ;

Enclosure 4 The following assistance will be needed from Maine Yankee Atomic Power Company:
- 1. Identify a key contact and an alternate.
Supply name, address, and phone number of utility contact person and an alternate to the LLNL project manager.
- 2. Participate with the Expert Panel, Peer Review Team and Analyst Team in conducting the review ,
Attend meetings as scheduled by mutual agreement, and provide input to the schedule.
Be available for interaction throughout the project and serve as liaison with the utility staff and contracters.
l 3. Supply information requested to carry out the review.
2 Plant-specific information and data must be readily available for the plant under review. This information includes, for example, the Safety Analysis Report (SAR), system descriptions, plant configuration diagrams, piping and instrument diagrams (P& ids),
operating procedures, and any other supporting documentation that gives details of the configuration, actuation, operation and control of the safety systems, and their supporting systems at the plant.
This information will be required by both the Systems and Fragility
, Analysis Teams conducting the review.
- 4. Organize two plant walkdowns.
Provide acceptable date, clearance and guides to carry out first and second plant walkdowns.
- 5. Review the draft report summarizing the seismic margin review.
l Provide comments for inclusion in project report.
