Dear Mr. Schwencer:
To resolve the concern of the NRC staff that premature diversion of the Low Pressure Coolant Injection (LPCI) flow to wetwell spray could adversely affect core cooling, the Susquehanna SES symptom based emergency procedures have been constructed to caution the operator against such diversion unless "adequate core cooling is assured."
These procedures, which were developed with the assistance of the BWR Owners Group and reviewed and accepted by the NRC staff, clearly identify LPCI diversion as secondary to the core cooling requirements except in those instances, outside the plant design envelope, which involve multiple failures and for which maintenance of containment integrity is required to minimize'risk to the environment.
This letter completes our action on SER Outstanding Issue 837.
Very truly yours, N.
W. Curtis Vice President-Engineering and Construction-Nuclear cc."
