(b) USNRC Letter to MYAPCo dated November 19, 1987 - Inspection

Report No. 87-16 (Environmental Qualification)

Subject: Reply to Notice of Violation

Gentlemen:

This reply is in response to the Notice of Violation contained in

Reference (b) pertaining to the qualification of electric equipment at Maine

Yankee.

Our reply follows the violation which has been repeated below for

completeness.

Violation

10 CFR 50.49 paragraphs (f) and (g) require that each item of electrical

l

equipment important to safety be qualified and that qualification must be

completed at a time no later than November 30, 1985.

Contrary to the above, on July 24, 1987, the qualification of Veam-Litton

connectors was not established at the time of this inspection in that (1)

the data of the type test results could not be provided at the time of the

inspection to verify the qualification of the connectors used for

thermocouple circuits, and (2) there was no similarity analysis between

the tested specimens and the installed connectors in the qualification

. file.

,

l

This is a Severity Level IV violation (Supplement 1).

Attention: Document Control Desk . HN-87-139

Maine Yankee Resoonse

The Litton-Veam Qualification Documentation Review (QOR) Package 3168 was

revised and issued on October 30, 1987. The revised QDR contains a

detailed similarity analysis, as well as a letter from the manufacturer

confirming the similarity between the test specimens and the installed

connector assemblies, that documents the qualification of the Litton-Veam

connectors.

With regard to the apparent lack of test data for the connectors in the

QDR, it is our understanding that the inspectors questioned the validity

of the thermocouple connector data contained in Test Report No. 558-1657

(pp. C-8 through C-10) because the input and output recordings were the

same at all temperature values, indicating 1001. accuracy of the

thermocouples that were presumed to be used.

As described in Appendix III of the abow referenced tu;t report,

thermocouples were not used in the test; thermocouple connector assemblies

were connected to a thermocouple calibrator on one end and a temperature

indicator on the other. Thus, the input and output test data were

unaffected by the commonly observed variations in thermocouple accuracy

over wide temperature ranges.

The possibility of an inadequate similarity analysis in the QOR was

identified prior to the inspection and we were in the process of updating

the QOR to include a detailed similarity analysis report. Completion of

the planned revisions to the existing QDRs should prevent a recurrence of

this discrepancy in the documentation of qualified electrical equipment

important to safety.

Full compliance was achieved on October 30, 1987.

Very truly yours,

MAINE YANKEE
