Docket No. 50-336 i

Mr. W. G. Counsil, Vice President Nuclear Engineering & Operations Northeast Nuclear Energy Compar.y P. O. Box 270 Hartford, Connecticut 06101 i

Dear Mr. Counsil.

RE: MILLSTONE NUCLEAR P3WER STATION, UNIT NO. 2 1

By letters dated October 26, 1978 and January 25, 1979, you submitted

+

proposed inservice inspection and testing Technical Specifications, a program description and a request for relief from selected ASME Code requirements pursuant to 10 CFR 50.55a(gf. Although we have not completed our detailed review of your submittals, our preliminary re-l view makes clear to us that your proposed p'ogram to implement those ASME Code requirements that you have found to be practical would in-

,:rease the scope of inservice inspection and testing for your facility beyond that currently required by your TetNmical Specifications. We have concluded that this upgrading of yourainservice inspection and testing program will further enhance safety.

Based on our preliminary review, we agree with your determination that it is impractical within the limitations of design, geometry and materials of construction of components, for you to meet certain of the specified ASME Code requirements and that imposition of those requirements would result in hardships or unusual difficulties without a compensating increase in the level of quality or safety. Therefore, pursuant to 10 CFR 50.55a(g)(6)(i), we hereby grant relief, on an interim basis, pending completion of our detailed review, from those inservice inspection and testing requirements of the ASME Code that you have requested. Moreover, since the scope of the inservice inspection and testing will be increased by your proposed program, and the granting of this relief is based only on the impracticality of selected ASME Code requirements, we have determined that the relief granted neither increases the probability or consequences of accidents previously considered r~, decreases safety margins and that, therefore, 't does not involve a fignificant hazarcs consiceration. Therefore, you are authorized to, and should proceed to, implement your prcposed program (except where your current Technical Specifications are more restrictive).

w wu

Northeast Nuclear Energy Co. During the period between now and the date we complete our detailed review of your submittal, you must comply with both your existing Technical Specifications and your proposed inservice inspection and testing program.

In the event conflicting requirements srise for some components, you must comply with the more restrictive requirements (e.g., shorter inspection intervals, increased number of parameters measured).

In other words, the granting of this relief from ASME Code requirements should not ce interpreted to give you relief from any of the requirements in your existing Technical Specifications.

When our detailed review of your submittals is complete we will:

(1) issut Tinal approval of your program (which may contain modificat ons resulting from the staff's review), (2) grant relief from any ASME Code requirements that are determined tc be impractical for your facility for the duration of the inspection interval and (3) issue appropriate changes to your Technical Specifications.

A copy of the Notice of Granting of Relief related to this action is enclosed.

Sincerely,

( g,/ h
