Dear Mr. Clark:
SUBJECT:
LOSS OF DECAY HEAT REMOVAL We have just issued Generic Letter 88-17 which addresses loss of decay heat remuval (DHR) during nonpower operation.
This letter was issued because of the potential serious consequence of loss of shutdown cooling concurrent with significant core decay heet.
Further, it is our belief 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) pravention 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 should immediately ease the concern; and parallel, but longer term, prograner.ed enhancements which effectively address the root cause of the problem and permit greater 'lexi-bility in operation.
We consider this issue to be of high priority and request that you assure that your organization addresses it accordingly.
Sincerely,
- c.db'jj Cr' Ther.asE.Eurley i
