C. 20555 Re: Docket No. 50-275, OL-DPR-80 Diablo Canyon Unit 1 Licensee Event Report 1-86-016-01 Main Steam Line Check Valve Inoperability Due to Retainer Nut Problems Gentlemen:
Pursuant to 10 CFR 50.73(a)(2)(vii) and 10 CFR 21.21, PGandE is submitting the enclosed revision to Licensee Event Report 1-86-016 concerning the problems with the retainer nut associated with the discs in the main steam line check valves. PGandE contacted the vendor, Shutte-Koerting Company; the vendor indicated that they would provide notification of this problem to all customers with check valves of a similar design. After further investigation on December 11, 1986, PGandE determined this event to be reportable in accordance with 10 CFR 21.21. This revision is being submitted to meet the reporting requirements of 10 CFR 21.21. A copy of PGandE Letter No.
DCL-86-347 has been enclosed as an attachment to the LER to provide additional information related to PGandE's handling of this event.
This event has in no way affected the public's health and safety.
Kindly acknowledge receipt of this material on the enclosed copy of this letter and return it in the enclosed addressed envelope.
