Gentlemen:

SUBJECT: INSPECTION NO. 50-029/86-18

Enclosed is the report of the team inspection conducted by Mr. G. T. Hubbard

and other NRC representatives on October 20-24, 1986, at the Yankee Atomic

Electric Company offices, Framingham, Massachusetts, and the Yankee Rowe

Nuclear Power Plant, Rowe, Massachusetts, of activi. ties authorized by NRC

License DPR-3. The team's findings were discussed with you and members of

your staff at the conclusion of the inspection. The inspection reviewed your

implementation of a program for establishing and maintaining the qualification

of electric equipment within the scope of 10 CFR 50.49. Within these areas, the

inspection consisted of examination of selected procedures and records, inter-

views with personnel, and observations by the inspectors.

The inspection determined that you have implemented a program to meet the

requirements of 10 CFR 50.49 except for the deficiency identified in the

enclosed inspection report. The deficiency, summarized in Appendix A, is

classified as a Potential Enforcement / Unresolved Item (PE/UI) and will be

referred to the NRC Region 1 Office for further action. The ceficiency

involved failure to ensure oualification of internal control wiring in safety-

related Limitorque motor valve operators.

Your corrective action regarding the identified deficiency was reviewed during

the inspection, and found acceptable.

We are available to discuss any questions you have concerning this inspection.

Sincerely,

o

APPENDIX A

Potential Enforcement / Unresolved Item

~

.

As a result of the equipment qualification (EQ) inspection on Qctober 20-24,

1986, the following item has been referred to NRC Region I as a Potential

Enforcement / Unresolved Item (paragraph references are to detailed portions

of the inspection report).

Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and sections 5.2.2 and

5.2.6 of the D0R Guidelines, Yankee Atomic Electric Company (YAEC) failed

to ensure that after the qualification deadline of June 1984 (second

refueling outage after March 31,1982) or after the extended deadline date

(with NRC Staff approved extensions) of November 30, 1985, outside contain-

ment Limitorque motor valve operators required to be qualified at Yankee Rowe

were in an installed condition similar to that in which they were tested in

that YAEC did not have assurance that internal control wiring was either the

^

'

same as that tested with the actuators or, if different, that it was qualified

separately. During the inspection, the NRC inspectors determined that

qualified wires were subsequently installed in the outside containment

Limitorque operators.
