Gentlemen:

SUBJECT: INSPECTION NO. 50-293/85-35

Enclosed is the report of the team inspection conducted by Mr. R. C. Wilson

and other NRC representatives on December 9 to 13, 1985, at your Braintree

engineering offices and the Pilgrim Nuclear Power Station of activities

authorized by NRC License No. DPR-35. 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 as required by 10 CFR

50.49 for establishing and maintaining the qualification of electric equipment

within the scope of 10 CFR 50.49. Within these areas, the inspection consisted

of examinations of selected procedures and records, interviews 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. Two deficiencies in your program implementation,

'

summarized in Appendix A, are classified as Potential Enforcement / Unresolved

Items and will be referred to the NRC Region I office for further action.

These deficiencies involve failure to fully document the qualification of

Barton 288A main steam flow switches and General Electric EB-25 terminal

blocks. Three additional concerns are classified as Open Items, and a

feture NRC inspection will review your actions concerning them. Details

of all the deficiencies and concerns a e discussed in the enclosed

inspection report.

Your corrective actions regarding the identified deficiencies and concerns

should not be delayed pending either a future NRC inspection or further action

by the NRC Region I office.

APPENDIX A

Potential Enforcement / Unresolved Items

As a result of the special equipment qualification inspection on December 9

to 13, 1985, the following items have been referred to NRC Region I as

Potential Enforcement / Unresolved Items (paragraph' references are to detailed

portions of the inspection report).

1. Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and Section 5.2.5 of

the D0R Guidelines, at the time of the inspection Boston Edison Company's

(BECO) files did not adequately demonstrate qualification of Barton 288A

main steam flow switches because of failure to demonstrate that plant

accuracy requirements are satisfied. (Paragraph 4.D(1), Item 50-293/

85-35-1.)

2. Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and Section 5.2.5 of

the 00R Guidelines, at the time of the inspection BEC0's files did not

adequately demonstrate qualification of General Electric EB-25 terminal

blocks because of failure to demonstrate that plant performance

requirements are satisfied.
