Dear Mr. Cornelius:
SUBJECT:
LOSS OF DECAY HEAT REMOVAL l
We have dust issued Generic Letter 88-17 which addresses loss of decay heat i
renoval (DHR) during nonpower cperation.
i This letter was issued because of the potential serious consequence of loss 9 shutdown cooling concurrent with significant core decay heat. Further, it is I
our belief that the industry as a whole has not aggressively responded to j
resolve the concern following its identification in our earlier Generic letter 87-12.
In particuler, 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 cora damage, and (3) t control of radioactive material if a core damage accident should occur.
Generic Letter 83-17 prescribes expeditious actions which should immediately r
ease the concern; and parallel, but longer tenn, 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.
Sincerely, orir!> n1 signed by 2 0:.3 3 }.. W rle y Thomas E. Hurley, Director Office of Nuclear Reactor Regulation f
