Docket flo. 50-285 11r. F. M. Petersen DEC I 21988 President and Chief Executive Officer Oraha Public Power District 1623 Harney Street Oraha, Nebraska 68102

Dear l'r. Petersen:

SUCJECT: LOSS OF DECAY HEAT FEt:0 VAL, FORT Cath 0'Jft STATION We have just issued Generic Letter 88-17 which addresses loss of decay heat reraoyal (DFF) during nonpower operation.

This lett(r 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 folicwing its identification in our earlier Ceneric 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) nitiga-tion of accidents before they potentially progress to core danage, and (3) centrol of radioactive naterial if a core dar: age accident should occur.

, Generic Letter 08-17 prescribes expediticus acticos which should irrediately case the concern; and parallel, tut longer tern, prograrred (rhanceraents which effectively address the root cause of the prc.blens and pernit greater flexi-bility in operation.

Ke consider this issue to be of high priority and request that you assure that your organization addresses it accordirgly.

Dear Mr. Petersen:

SUCJECT: LOSS OF DECAY HEAT REP.0 VAL, FORT CALHOUN STATION We have just issued Generic Letter 88-17 which addresses loss of decay heat renoval(CPR)furingnonpoweroperation.

This letter was issued because of the potential serious consequence of loss of shutdown cooling concurrent with significant core decay heat. Furt'.er, 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) mitiga-tion of accidents before they potentially progress to core damage, and (3) centrol of radioactive material if a core damage accident should occur.

Generic Letter 88-17 prescribes expeditious actions which sheuld irmediately case the con:ern; and parallel, but longer term, prograrred enhancements which effectively address the root cause of the probleros and pernit greater flexi-bility in operation.

We cor sider this issue to be of high priority ar,d request that you assure that your organization addresses it accordingly.

Sincerely,
