Attention: Mr. Darrell Eisenhut, Director United States Huclear Regulatory Commission Washington, D. C. 20555

Dear hlr. Eisenhut:

As outlined in our October 27, 1980 letter, modifications to the scram discharge system will be completed by the end of the current refueling outage. These will establish compliance with the criteria developed by the BWR Owners subgroup. Exceptions to this are presented in our January 30, 1981 letter. The staff's Generic Safety Evaluation Report on BWP. Scram Discharge System indicated that these criteria provided an acceptable basis for resolution of problems associated with the scram discharge system.

It is Hiagara Mohawk's understanding that compliance with these criteria eliminates the need for interim actions. Therefore, the equipment for continuous monitoring of the scram discharge system headers (i.e., UT equipment) will not be reinstalled.

Sincerely, NIAGARA MOHAWK POWER CORPORATIOH D. P. Disc Vice President Engineering BDW:ja
