Docket No. 50 344 MAR 21 G1 Mr. James E. Cross

" trm"n m mnanw-Vice President, Nuclear Portland Generai Electric Company 121 S. W. Salmon Street Portland, Oregon 97204

SUBJECT:

OPERATIONAL EVENTS WHILE SHUTDOWN The NRC has just issued Information Notice 9122, "Four Plant Outage Events Involving Loss of AC Power or Coolant Spills," which addresses recent events that occurred during shutdown operations.

The chief purpose of this information notice is to notify each licensee that the high rate of precursor events to loss of decay heat removal during shutdown is a source of concern to the NRC. All of the events discussed in this information notice occurred during a one. week period in March 1991.

Because of the potential for loss of a critical safety function in these and similar events, I believe a high level of management attention is required in the planning, coordination, and execution o' shutdown operations.

While this information notice does not require specific licensee action or response, I urge you to give this important matter your personal attention.

Sincerely, oric1 H sinne( cy 1'he w E. Murlcy Thomas E. Murley, Director Office of Nuclear Reactor Regulation cc: See next page DISTRIBUTION Doc ketJ11ei NRC & LPDRs PDS r/f BBoger CGrimes DFoster 4
