TOPICS FOR BRIEFING ON DAVIS-BESSE REQUESTED BY j RICHARD UDELL AND RELATED REQUESTS I

'i In preparation for the Markey Subcommittee hearing on Davis-Besse, Mr.

Udell of the Subcommittee staff has made the following requests:

1. An August 5,1985 memorandum from Mr. Dircks to Chairman Palladino i summarized the responses of project managers concerning operating

.1 nuclear power plants where required corrective action has been l outstanding for an extended period of time. Mr. Udell requests a copy l of the actual response submitted by each project manager, i 1

2. An August 5 memorandum from Mr. Dircks to Office Directors asked, in light of the Davis-Besse incident, how NRC programs could be made more effective. Mr. Udell requests copies of the responses to that memorandum.

3. There is a maintenance inspection at Davis-Besse this week. When it is available, Mr. Udell requests a copy of the report or document generated as a result of that inspection.

! 4. As I mentioned this afternoon in our telephone conversation, Mr. Udell i requests a briefing on Davis-Besse and proposes Tuesday, September 24 i at 2 P.M. as the date and time. The areas to be covered in this -

briefing are:

- NRC's current views of the utility analysis and the Los Alamos

, study concerning feed and bleed at Davis-Besse.

i - An expansion of the NRC response to Question 12 in our letter to .

Mr. Markey dated July 12, 1985. This expansion would extend the response concerning aux feed reliability to all operating power reactors.

l - Information on how the core melt frequency calculations in the

! January 16, 1984 memorandum from Thadani to Parr came about.

i - In the September 18th briefing before the Commission, the Staff ,

mentioned efforts to increase aux feed reliability at some

. plants. Mr. Udell would like to discuss the specific plants and, +

if there is a CRGR package, he would like to obtain a copy of it.

- Generic implications of the Davis-Besse incident.

- INP0 activities at Davis-Besse, including staff access to INP0 documents on the plant and whether INP0 anticipated the problems at Davis-Besse.

- The grandfathering process as it relates to GDC and SRP requirements, including what plants have to comply with which requirements and how this is determined.

! - The number of failures at Davis-Resse, their causes, their

! estimated probability and the combined probability of occurrence.

This relates to our response to Question 2 in the NRC response to Mr. Markey dated July 17, 1985.

- Prerequisites to restart, including IE issues such as pending enforcement action as a result of the incident. ,
