SUBJECT:

LOSS OF DECAY HEAT REMOVAL i

I We have just issued Generic Letter 88-17 which addresses loss of decay heat removal (DHR) during nonpower operation.

i This letter was issued because of the potential serious consequence of loss of shutdown cooling concurrent with significant core decay heat. Further, it is our belief that the industry as a whole has not aggressively responded to resolve the concern follswing its identification in our urlier Generic letter 87 12.

In particular, the industry's response to the Generic Letter 8712 was deficient in the areas of (1) prevention of accident initiation. (2) mition.

tion of accidents before they potentially ptogress to core damage, and (3) control of radioactive material if a core damage accident should occur.

Generic Letter 88 17 prescribes expeditious actions which should immediately ease the concern; and parallel, but longer term, pregramed enhancements which effectively address the root cause of the problems and permit greater flexi.

bility in operation.

1 We consider this issue to be of high priority and request that you assure that your organization addresses it accordingly.

Sincerely.
