0 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 Docket Nos.
50-259/260/296 October 6, 1987 LICENSEE: Tennessee Valley Authority FACILITY; Browns Ferry Nuclear Plant, Units 1, 2 and 3
SUBJECT:
'UMMARY OF MEETINGS HELD ON SEPTEMBER 15, 1987 BETWEEN TVA AND NRC CONCERNING THE DELTAS IN MAJOR PROGRAMS BETWEEN THE SEQUOYAH AND BROMNS FERRY NUCLEAR PERFORMANCE PLANS (TAC NO. 62247)
On September 15,
- 1987, a meeting was held in Bethesda between the OSP staff and representatives of TVA for the purpose of the OSP technical staff being briefed on the differences
("deltas" ) between the Browns Ferry and Sequoyah programs in an effort to assist the staff in resolving resource and scheduling
. conflicts and to become better acquainted with the Browns Ferry technical staff.
The following programs were discussed at the meetings:
1.
guality Assurance 2.
Piece-Parts Procurement 3.
Environmental Oualification 4.
Melding 5.
Heat Code Program 6.
Moderate Energy Line Break Analysis Attachment 1 is the list of attendees.
Attachment 2 contains program descrip-tions presented by TVA during the meeting.
The meetings provided the OSP staff with useful information regarding similarity and differences between the above Sequoyah and Browns Ferry programs'.
The meetings resulted in the following TVA action items:
1.
TVA will make available to the OSP staff the detail plans of Moderate Energy Line Break Analysis.
2.
TVA will provide greater details of Heat Code
- Program, because it is a
new topic in Revision 1 of Volume 3 of the Browns Ferry Nuclear Performance Plan.

3.
TVA would provide a firm dated for a 30% Eg binder inspection, because of the many schedule slippages TVA has had in this area.
