Subject:

McGuire Nuclear Station, Unit 1 Docket No. 50-369 LER 369/84-05 Gentlemen:

My letter dated April 2, 1984 submitted License Event Report 369/84-05. On page 3 of that report it was incorrectly stated that "After the blackout signal was cleared, ND pump 1B was returned to service for core cooling". As indi-cated elsewhere in the report, the ND pump was actually returned to service within three minutes of the blackout signal which had caused it to stop due to Load Shedding (The blackout signal wasn't cleared until about 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> later).

Therefore the affected paragraph should read "ND pump 1B was returned to service for core cooling. After the blackout signal was cleared, NV pump 1F and D/G 1B were returned to standby readiness". We regret any confusion or inconvenience this may have caused.

Very truly yours,
