SUBJECT:

LOSS OF DECAY HEAT REMOVAL (TAC 69739)

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

This letter was issued because of the potential serious consequence of loss of shutdown cooling c3ncurrent with significant core decay heat. Further, it is our belief that the industry as a whole has not aggressively responded to resolve the concern following its identifit.ation 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) mitiga-tion of accidents before they potentially progress to core damage, and (3) control of radioactive material if a core damage accident should occur.

Generic Letter 88-17 prescribes expeditious actions which shyJ1d ininediately ease the epicern; and parallel, but longer tenn, pro 3 rammed enhancements which effectively address the root cause of the problems and permit greater flexi-bility in operation.

We consider this issue to :Je of high priority and request that you anure that your organization addresses it accordingly.

Sincerely.
