~
-i '
LPackages 5.10 and'11.20 were replaced and are no longer suspect breakers. Tne circuit breaker in Package 9.10 was'not purchased between August 1, 1983, and August-1,.1988,:and is,x therefore,'not' subject to the requirements of NRC ,
. Bulletin 88-10'. .Because of more recent'~ replacements, Packages 25.10, 26.20,
, 1 126.21, rand 26 45.have been superseded by Packages 80.32, 55.29, 67.39, and 40.'60, respectively.
.< Y 1 Packages 12.10'and 35.01 have been added to the listing. These two essential raw cooling water breakers supply non-Class-1E loads from Class 1E panels, m They-were. Identified in SQN's original search for Bulletin 88-10 and were
. misclassified as no'n-Class-1E breakers. A review of other breakers for <
non-Class-1E loads that are installed in Cless 1E panels has not identified anyTacdition&l misclassified breakers.
'y . Package 134.10.has'been added to the listing. This circuit breaker was inadvertently replaced with a suspect breaker in June 1989.

w l Packages 50.01 through 68.98 have been added to the listing. The breakers in ,
s, these packages were all installed by Engineering Change Notice (ECN) L6883.
? .It'has been determined that the oversight of three of the ECN L6883 workplans '
was due to a previous memorandum issued concerning the traceability of the one b _ECN L6883 workplan addressed in Reference 1. It was incorrectly assumed that
( all ECN L6883 workplans.had been reviewed and untraceable breaker; were only
[ identified on- the one workplan.
L~
'In accordance with the requirements of Bulletin 88-10, each of the packages noted above as being additions to the listing have a justification for continued operation in place.
Packages 80.01 through 80.42 have been added to the listing. These breakers
- were procured for installation in the plant as direct-charge maintenance t-breakers % Direct-charge material is material that has been preidentified and l- , procured for a' specific-job, as opposed to stock material.) As'a result of identifying packages 80.01 through 80.42, an evaluation of TVA's original
- : review for Bulletin 88-10 was performed. It has beeri determined that all
- direct-charge molded-case circuit breakers were not identified initially. TVA has developed an action plan to identify untraceabla direct-charge breakers.
The installetion location of-any additional untraceable breakers will be determined by December 31, 1989. In accordance with the bulletin requirements, all of these additional breakers will either be replaced or have a justification for continued operation in place by January 30, 1990.
As a result of the-large number of-additional breakers to be replaced, TVA is clarifying-Commitment 4 for SQN as it was. stated in Enclosure 4 of Reference 1... The, breakers will be replaced in accordance with the schedule in Bulletin 88-10. However, since the number is now greater than 75 per unit, one-half of the breakers for each unit will be replaced before startup after s the Cycle 4. refueling outages and_one-half will be replaced before startup after the Cycle 5 refueling outages.
A summary statement of the commitments contained in this submittal is provided in Enclosure 2. Please direct questions concerning this issue to K..S. Whitaker at (615) 843-7748.
Very truly yours, TENNESSEE VALLEY AUTHORITY .
