Dear t',
- r. Dunn:
SUBJECT:
INADVERTENT SAFETY INJECTION DURING C00LDOWN The Division of Operating Reactors has completed a generic bounding review on this subject and concludes that no further licensing action is necessary at this time since it is likely that a facility could withstand more than fifty inadvertent ECCS actuations.
We have concluded, however, that it would be prudent, should a facility experience core than twenty-five such j
injections, for you to consider a plant specific analysis for that facility which would identify more precisely the additional number of actuations L
that can be safely accommodated at that facility.
A copy of our Safety Evaluation Report is enclosed.
Si ncerely, '
,b J.'
