Docket Nos. 50-313 and 50-368 DEC b'2 Jggg Mr. Jerry L. Maulden President and Chief Executive Officer Arkansas Power and Light Company Post Office Box 551

- Little Rock, Arkansas 72203

SUBJECT:

LOSS OF DECAY HEAT REMOVAL, ARKAt(SAS HUCLEAR ONE, UNITS 1 AND 2 We have just issued Generic Letter 88-17 which addresses loss of decay heat removal (Di!R)duringnonpoweroperation.

This letter was issued because of the potential serious consequence of loss of shutdown cooling concurrent with significant core decay heat. Further, it is

. cur 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) 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 should imediately ease the concern; and parallel, but longer term, programmed enhancements which effectively address the root cause of the problems and permit greater flexi-bility in operation.

We consider this issue to be of high priority and request that you assure that

your organization addresses it accordingly.
