O MAR 21141 Docket No. 50-443 Hr. Ted feigenbaum, President and Chie' Executive Officer New Hampshire Yankee Division Public Service Company of New llampshire P. O. Itox 300 Seabrook, New }!ampshire 03874 i

SUBJECT:

OPERATIOMAL EVENTS MHILE SilVTDOWN The NRC has just issued Inf0rmation Not4.ce 91 22, "rour 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 of shutdown operations.

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

Sincerely, Original nigned by h u nf.Murley Thomas E. Hurley, Director Office of Nuclear Reactor Regulation cc: See next page OFC
