Subject:

SEP Topic V-5, Reactor Coolant Pressure Boundary Leak Detection R.

E. Ginna Nuclear Power Plant Docket No. 50-244

Dear Mr. Crutchfield:

Rochester Gas and Electric submitted comments on the subject SEP topic by letter dated October 12, 1981.

An error has been noted in Table 1 attached to that letter.

Item 8, Containment Atmosphere Temperature Monitoring, does not have control room indication.

This error has been corrected in the attached revised Table 1.

Since regulatory criteria do not require control room indication for this parameter, there is no effect on the conclusion noted in our October 12, 1981 letter.

Very truly yours, Jo n E. Maier Attachment xc:
