SUBJECT: INSPECTION REPORT NOS. 50-327/87-31 AND 50-328/87-31

1

This letter forwards the results of a special inspection of TVA's Design

Baseline and Verification Program (DBVP) for the Sequoyah Nuclear Power

Plant, conducted at the plant site and in your Cedar Bluffs Offices between l

June 29 and July 24, 1987. The NRC inspection team was comprised of a multi- .

discipline team of personnel from the Office of Nuclear Reactor Regulation l

from consulting firms, and from the Region II Office. The team concentrated on '

the resolution and corrective action for the findings of the DBVP. The team

also reviewed the corrective actions resulting from independent oversight of

this program by TVA's Engineering Assurance group and evaluated TVA's actions

in response to previous NRC design control and DBVP inspection reports. TVA

internal reports (1) EA-0R-001, Engineering Assurance Oversight Review Report,

"Sequoyah Nuclear Plant - Unit 2 Design B3seline and Verification Program,"

dated April 29, 1987, and (2) the SQN DBVP Unit 2 Phase I report, dated May 29,

1987, characterize the program, its findings, and the Engineering Assurance

oversight effort. These reports were also reviewed during this inspection.

As a result of the inspection, the NRC team concluded that the DBVP was generally

conducted in accordance with the program plan. Implementation by bc'th DBVP

personnel and the Engineering Assurance oversight group appears to have been

_

adequate in most instances sampled by the inspection team within the scope of

the program areas inspected to date.

As noted in the report, implementation of corrective actions for DBVP findings

was still in progress at the time of the inspection, as was Engineering

Assurance (EA) sampling and verification of implementation. We note that a

supplemental report addressing EA oversight of the DBVP has been submitted to

the NRC (R. Gridley letter dated October 23, 1987). In order for the NRC to

assess the adequacy of the DBVP effort to support plant restart, the supplemen-

tal Engineering Ass.urance Oversight Report remains to be reviewed by the NRC.

Results of the inspection are presented in the enclosure.

TVA provided a written response (R. Gridley letter dated October 27, 1987)

addressing the observations identified in Appendix A of the enclosed report in

advance of the issuing of this report. The substance of these observations had

been communicated verbally to TVA during the inspection. An additional NRC

inspection (Report 327, 328/87-64) was conducted on October 26-30, 1987. This

subsequent inspection addressed many of the open observations addressed in the-

enclosed report. .The NRC's evaluation of your response to this letter will be

documented in inspection report 327, 328/87-64. Any observations remaining

open at restart will require an evaluation _ of acceptability for such restart by

both TVA and the NRC.

In accordance with 10 CFR 2.790(a), a copy of this letter and the enclosure will

be placed in the NRC Public Document Room.

Should you have'any questions concerning this inspection, please contact me or

Mr. Gene Imbro, (301) 492-9664.

Sincerely,
