Dear fir. Withers:
StrCJECT: LOSS OF DECAY 11 EAT REPOYAL, WOLF CREEK CEf.ERATit;G $1AT10fl We hat 'ust issued Generic Letter F8-17 which addresses loss of decay beat reroval {DFR) during r.onpower operation.
This lett(r was issued because of the rotential sericus consequence of loss of shutdown cooling concurrent with significant core decay tcat.
Further, it is cur Lelief that the irdustry as a whole has not aggressivtly responded to resolve the concern follcwirg its identification in our earlier Gercric Letter 87-12.
In particular, the industry's response to the Generic Letter 87-12 was deficient in the areas of (1) preventier. of accident initiation, (2) uitiga-tion of accidents before they potentially progress to core darage, and (3) control of radioactive ctaterial if a core danage accident shculd occur.
Gere-ic Lett(r EC-17 prescribes expeditious acticns which shculd ircediately case the concern; and rarallel, but longer tern, prograrried er hancer'ents which effectively eddress the root cause of the prcblens and pernit greater flexi-bility 11 operation.
We consider this issue to be of high priority ard request that ycu assure that your organization addresses it accordirgly.

SUEJECT: LOSS OF DECAY HEAT ret'0 VAL, WOLF CREEK GENERATlhG STATI0il i
We have 'ust issued Geneiic Letter 88-17 which addresses loss of decay heat renovalf0PR)duringnonp1weroperation.
l This letter was issued because of the potential serious consequence of loss of I
shutdown cooling concuirent with significant core decay heat.
Further, it is our belief that the indust *y as a whole has not aggressively responded to resolve the concern follow',ng its identification in our earlier Generic Letter 87-12.
In particular, the industry's response to the Generic Letter 87-10 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 catcrial if a core damage accident should occur.
Generic Letter 88-17 prescribes expeditious actions which shculd imediately case the concern; and paral'el, but longer tern, pregrarried enhancencnts which effectively address the root cause of the problems and permit greater flexi-i bility in operation.
I We consider this issue to be of high priority and request that you assure that your organization addresses it accordingly.
Sincerely,
%^
