Dear Mr. Carlson:

Re: Nine Mile Point Unit 2 Docket No. 50-410 On April 10, 1980, your staff was informed by -telephone of a potential reportable deficiency in accordance with 10CFR50.55(e). This deficiency concerns the environmental and seismic qualifications of some electrical equipment to be used at Nine Mile Point Unit 2. In accordance with paragraph 50.55(e)(3) of the Commission's Regulations, attached is a final report which provides a description of the deficiency, an analysis of the the corrective action taken. safety.'mplicationsand Very truly yours, NIAGARA M WK POWER CORPORATION c ..~.:

FINAL REPORT t t'i tel . () f Qualification of Electrical E ui ment Descri tion of the Deficienc During an audit of our nuclear steam supply system Vendor conducted the week of March 26, 1980, no evidence (lack of documentation) was found to indicate that the three electrical instruments indicated below were adequately qualified: .

Instrument MPL No. Qualification Lackin Conductivity Element E12-N001 Environmental and Seismic Level Transmitter E12-N008 Environmental and Seismic Rosemount Model 1151DP E12-N058 Environmental Test Differential Pressure Incomplete Transmitter II. Subse uent Findin s and Corrective Action As indicated in our interim report dated May 12, 1980 for the Rosemount Model 1151DP differential pressure transmitter, an additional search of

'he qualification records following the audit located the qualification documentation in another record file. To prevent the recurrence of being unable to retrieve documentation in a timely manner, the nuclear steam supply system Vendor's Quality Assurance Program is being modified to cross-reference qualification records and vendor-supplied documentation.

Regarding conductivity element E12-N001 and level transmitter E12-N008, it has been determined that no corrective action is required. These instruments are considered to be passive and are not required to function either during or after a design basis accident. Since a failure analysis shows that an electrical short circuit or open circuit in the instrument can damage the power source, no additional qualification is required.

III. Anal ses of the Safet Im lications The electrical instruments have been shown to be adequately qualified to satisfy their intended design function. Therefore, this condition could not have adversely affected the safety of operation of Nine Mile Point Unit 2 at anytime throughout its expected lifetime.
