SUBJECT:

LOSS OF DECAY HEAT REMOVAL We have just issued Generic Letter 88-17 which addresses the loss of decay heat rencval (DHR) during nonpower operation.

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 beliif that the industry as a whole has not aggressively responded to resolve the concern following its identification in our earlier Generic Letter 87-12. In particular, the industry's response to the Generic Letter 87-12 was deficient in the areas of (1) prevention of accident initiation, (2) miti gation of accidents before they rotentially progress to core damage, and (3) control of radioactive material if a core damage accident should occur.

Generic Letter 88-17 pretcribes expeditious actions which should irewdiately ease the Concerns; and parallel, but longer term, programed enhancements which effectively address the ruot cause of the problems and permit greater flexibility in operation.

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

Sincerely.
