Dear !!r. Jorjan:

SUBJECT:

LOSS OF DECAY HEA1 REliOVAL, SOUTH TEXAS PROJECT, UNITS 1 AND 2 We have just issued Generic Letter 88-17 which addresses loss of decay heat renoval(DHR)duringnonpoweroperation.

2 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) 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 imediately ease the concern; and parallel, but longer term, programed 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.
