TENNESSEE 37401 SN 157B Lookout Place WEN 211987 U.S. Nuclear Regulatory Connaission Attn: Document Control Desk Office of Nuclear Reactor Regulation Washington, D.C. 20555 Attention: Dr. J. Nelson Grace BELLEFONTE NUCLEAR PLANT (BLN) UNITS 1 AND 2 - UPDATE OF 10 CFR 50.55(e)'
REPORT AND OUTSTANDING COMMITMENT COMPLETION SCHEDULES Enclosed are two lists revising connaitment completion dates for 10 CFR 50.55(e) final reports. These revisions are in addition to those submitted in J. W. Hufham's letter to you dated December 17, 1985 on the same subject.
Enclosure 1 lists 10 CFR 50.55(e) items which were conunitted to before completion dates but which were found by a TVA independent (peer) review to require additional work. These items will be completed at least six months before fuel loading.
Enclosure 2 lists 10 CFR 50.55(e) items which are scheduled to undergo peer review. These items have had their peer review schedule delayed because of manpower limitations and the slowdown of work associated with the revision in the fuel loading schedule for BLN unit 1. The peer reviews on these items and any associated additional work will be completed at least six months before
! fuel loading.
A revised final report will be submitted when the scope / resolution of an item changes. Work will still be scheduled internally by specific dates.
As agreed to in our meeting in Atlanta on November 7, 1985, TVA will keep the BLN resident inspector informed of early completion of any of the items in enclosure 1 or 2 to aid NRC in scheduling its work.
If you have any questions on this matter, please get in touch with D. L. Terrill at (205) 574-8820.
