-This letter provides an additional revision to Enclosure 1 of Reference i for SQN.

Earlier corrections were provided by References 2 and 3.

For your convenience, a corrected copy of Attachment 2 to Enclosure 1 is provided with revision bars in the margin.

An evaluation of TVA's original review process for Bulletin 88-10 was performed in accordance with the action plan described in Reference 3.

As a result of this evaluation, Packages 80.60 through 80.69 have been added to the listing that identifies the suspect molded-case circuit breakers installed at SQN.

These ten breakers were procured for installation in the

  1. D plant as' direct-charge breakers.

(Direct-charge material is material that has been preidentified and procured for a specific job, as opposed to stock material.)

'hTVAhasbeenunabletoverifythatalldirect-chargebreakerspurchased oo between August 1983 and December 1984 have been identified.

Separate R $

procurement records for SQN have been maintained at SQN for direct-charge pr'ocurement since January 1985, allowing the direct review for molded-case gno circuit breakers.

In addition, the records system for the distribution of o8 direct. charge material to the field also changed around that time, gc facilitating the review for molded-case circuit breakers.

To identify m

additional molded-case circuit breakers procured as direct-charge breakers for 8$

i M tallation at SQN between August 1983 and December 1984 would require a Mo'searth of all work requests and workplans issued at SQN for the August 1983 to December 19M period.

The large volun1e of recoi ds ma' es that search resource intensive.

E t.

k' U.S. Nuclear Regulatory Commission MAR 201990 In TVA's search for direct-charge breakers, only ten additional breakers were identified for the January 1985 to August 1988 period. These ten breakers came from the same contract, Contract 87PLE-839215, which was used extensively to procure material needed on short notice to support SQN's restart effort.

Additionally, to ensure operability the equivalent of the standard technical specification surveillance testing was performed at the time of replacement on more than 96 percent of the untraceable molded-case circuit breakers procured and installed in safety-related applications at SQN between August 1983 and August 1988.

While the surveillances are not equivalent to the test program described in Attachment 1 to NRC Bulletin 88-10, they do provide reasonable assurance regarding the proper operation of the breakers, i

Since the number of additional direct-charge breakers procured between August 1983 and December 1984 is anticipated to be quite small, and our experience indicates that surveillance testing was most likely performed on breakers placed in service in Class IE applications, TVA proposes no further review to identify direct-charge breakers procured between August 1983 anJ December 1984.

TVA has concluded that no significant assurance would be expected from the additional resource expenditures.

Stock material for the entire August 1983 to August 1988 period, and direct-charge procurements for the January 1985 to August 1988 period have been reviewed.

No further reviews are planned.

In accordance with the bulletin requirements, the ten additional breakers have a justification for continued operation in place and TVA's schedule for breaker replacements remains as described in Reference 3.

No commitments are contained in this submittal.

Please direct questions concerning this issue to Kathy S. Whitaker at (615) 843-7748.

Very truly yours, TENNESSEE VALLEY AUTHORITY q
