SUBJECT:

BROWNS FERRY NUCLEAR PLANT (BFN) DETAILED CONTROL ROOM DESIGN REVIEW (TACS56104,56105,56106)

We have completed our initial review of your supplemental Detailed Control Room l Design Review (DCRDR) sumary report of November 9,1988. While the task ,

l analysis and control room inventory documented in this . supplemental report l appear to adequately meet the NUREG-0737 criteria pertaining to these activities, your determination of the restart applicability of Human Engineering Discrepancies (HEDs) seems questionable. Our staff's concerns ,

arise from a comparison'of the HEDs with the Restart Criteria provided in l Table IV-1 of the Browns Ferry Nuclear Performance Plan (BFNPP). Specifically, Criterion 1 of this Table states: i l

The item identifies a specific deficiency which has significant probability of leading to the inoperability of a system required for  ;

startup or operation by the BFN Technical Specifications.

The Category 1 HEDs enumerated in the supplemental summary report (HEDs 300 and 311) document deficiencies which may cause operator error and, therefore, result in challenges to critical safety functions. These conditions appear to meet the BFNPP restart criteria. As well, the staff feels that several otner HEDs of less severe categories (HEDs 299, 302, 305, 306, and 308) may also meet the restart criteria.

Following a sampling of HEDs identified during the original BFN DCRDR, we have also developed concerns regarding the restart applicability-of the following HEDs:

Category 1 12, 72, 189, 190, 273, 283, and 284 Category 2 157 and 280  ;

We desire to meet with your staff regarding the restart applicability of all l HEDs discussed in the preceding paragraphs. During this meeting, we would like to review your restart criteria against these HEDs and any documentation resulting from the restart evaluations performed on these'HEDs. TVA's l commitment to evaluate all HEDs versus the restart criteria was made during the DCRDR pre-implementation audit, and is documented on Page 13 of the Technical
