NPF-4 U. S. Nuclear Regulatory Commission NPF-7 Washington, DC 20555 Gentlemen:
ENVIRONMENTAL CUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT NORTH ANNA POWER STATION UNIT NOS.1 AND 2 Our letter of May 20, 1983, Serial Number 110D, provided our response to 10 CFR Part 50, paragraph 50.49(g). Subsequent to the issuance of our response, events have occurred at North Anna Power Station which require that modifications to the response be effected.
During start up of North Anna Power Station Unit No. 2 after refueling, tha failure of an inordinate percentage of Weed Instrument Company Resistance Temperature Detectors (RTD's) required that they be replaced with Rosemount RTD's. The circumstances of these events were documented in our letters of May 27,1983 (Serial Numbers 257A and 331).
Since the Rosemount RTD's have only a limited qualification, a change to the Environmental Qualification Master List from that submitted on May 20, 1983 is required. Enclosure 1 provides the revised Master List pages which reflects the required replacement of these RTD's. The present schedule for upgrade of the RTD's is as stated in the May 20, 1983 response.
Yours very truly,
[
