Docket No. 50-244 DEC.
~ 198B Mr. Paul Briggs Chairman of the Board and Chief Executive Officer Rochester Gas 8 Electric Corporation 89 East Avenue Rochester, New York 14649
Dear Mr. Kober:
SUBJECT:
LOSS OF DECAY HEAT REMOVAL We have just issued Generic Letter 88-17 which addresses loss of decay heat 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 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) prevention of accident initiation, (2) mitigation 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 flexibilityin operation.
We consider this issue to be of high priority and request that you assure that your organization addresses it accordingly.
Sincerely, ppiginal signed b7, Tl emas E, Muxley Thomas E. Murley, Director Office of Nuclear Reactor Regulation cc:

Dear Mr. Mecredy:
SUBJECT:
LOSS OF DECAY HEAT REMOVAL Me have just issued Generic Letter 88-17 which address loss of decay heat removal (DHR) during nonpower operation.
This letter was issued because of the potential s
ious consequence of loss of shutdown cooling concurrent with significant cor decay heat.
Further, it is our belief that the industry as a whole has no aggressively responded to resolve the concern following its identificat'on in our earlier Generic Letter 87-12.
In particular, the industry's respo e to the Generic Letter 87-12 was deficient in the areas of (1) prevention o
accident initiation, (2) mitigation of accidents before they potentially pro ess to core

Generic Letter 88-17 prescribes expeditious ac ions which should immediately ease the concern; and parallel, but longer ter
