SUBJECT:

INADVERTENT SAFETY INJECTION DURING C00LDOWN The Division of Operating Reactors has completed a generic beunding 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 wculd be prudent, should a facility experience more than twenty-five such injections, for you to consider a plant specific analysis for that facility which would identify nore precise.y the additional number of actuations that can be safely accoccodated at that facility.

A copy of our Safety Evaluation Report is enclosed.

s Si ncerely,

A. Schwencer, Chief Operating Reactors Branch #1 Division of Operr. ting Reactors
