Dear Dr. Grace:

BELLEFONTE NUCLEAR PLANT UNIIS 1 AND 2 - FAILURE TO ADEQUATELY DISPOSITION REPORTABLE NONCONFORMANCES IN THE DIVISIONS OF NUCLEAR ENGINEERING AND NUCLEAR CONSTRUCTION - SLRD-50-438/86-06, BLRD-50-439/86 FIRST INTERIM REPORT The subject deficiency was initially reported to NRC-01E Inspector Art Johnson on February 24 and February 28, 1986 in accordance with 10 CFR 50.55(e) as SCRs BLN 4703 and BLN CEB 8604, 8605, 8606 respectively.

Enclosed is our first interim report. We expect to submit our final repert no later than one year before fuel loading of unit 1.

A delay of a few days in tre submittal of this report was discussed with NRC-0IE Inspector Art Johnson on March 27, 1986.

If there are any questions, please get in touch with R. H. Shell at FTS 858-2688.

Very truly yours, TENNESSEE VALLEY AUTHORITY l 5.

. ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 FAILURE TO ADEQUATELY DISPOSITION REPORTABLE NONCONFORMANCES IN THE DIVISIONS OF NUCLEAP ENGINEERING AND NUCLEAR CONSTRUCTION BLRD-50-438/86-06 AND BLRD-50-439/86-05 h 10 CFR 50.55(e)

SCR BLN 4703 AND SCR BLN CEB 8604 FIRST INTRRIM RRPORT Description of Deficiency In performing independent (" peer") reviews on 10 CFR 50.55(e) reportable nonconformance reports /significant condition reports (NCRs/SCRs), which were believed to be completed and ready for NRC closure, approximately 50 percent of the items were found to be incomplete for a variety of reasons, including inadequate or incomplete corrective actions (both in TVA's Division of Nuclear Engineering and Division of Nuclear Construction); incomplete, inadequate, or nonexistant review for generic implications; and inadequate action required to prevent recurrence. Based on these results, it is believed that a similar condition may exist for all TVA plants and may also apply to responses to violations or other responses made to NRC that contain significant commitments to NRC for TVA actions or design changes.

Examples of this are found in Bellefonte Nuclear Plant (BLN) SCR BLN 4703 and SCR BLN CEB 8604, 8605, and 8606, which were evaluated as reportable under 10 j

CFR 50.5 (e), and SCR BLN CEB 8607, 8608, and 8609, which were nonceportable.

This type of problem was also exhibited to some degree in the violation

]

1 received by TVA on Watts Bar Nuclear Plant concerning Control Room Design Review descrepancies, which was one of the factors resulting in the performance of the peer review for BLN items.

1 Safety Implications Failure to fully complete corrective actions, action required to prevent recurrence, or failure to perform adequate review for generic implications may result in an unsafe condition remaining uncorrected. As a result, the safe operation of the plant might be jeopardized.

Interim Progress The Bellefonte Site Director has issued R requirement for peer review of I,

all significant 50.55(e) items and violatic.s that contain significant corrective actions. This will be implemented in the Bellefonte Project Manual by June 30, 1986, and will ensure that final configurations and documentation meet commitments made in those responses and will emphasize consideration of aspects of a deficiency outside of those identified on the NCR or SCR being dispositioned.

TVA is in the process of issuing a generic SCR (SCR GEN NEB 8603) describing this condition as potentially applicable to all TVA plants. The need for further corrective actions, and actions to prevent recurrence for BLN and other TVA plants, will be evaluated in disposition of the generic SCR.

The final report on this matter will be provided upon completion but no later than one year before fuel loading of unit 1.
