Docket Nos. 50 029 DEC 2 1933 Mr. James E. Tribble President Yankee Atomic Electric Company 580 Main Street Bolton, Massachusetts 01740-1398

SUBJECT:

LOSS OF DECAY HEAT REMOVAL We have just issued Generic letter 8817 which addresses loss of decay heat l

removal (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 L

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 8712 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 immediately ease the concern; and parallel, but longer term, programmed enhancements which effectively address the root cause of the problems and permit greater flext-bility in operation, r

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