May 6, 1986 Docket No. 50-336 D I (o Mr. John F. Opeka, Senior Vice President Nuclear Engineering and Operations Northeast Nuclear Energy Company P.O. Box 270 Hartford, Connecticut 06141-0270

Subject:

REQUEST FOR RELIEF FROM INSERVICE TESTING (IST)

REQUIREMENTS FOR MILLSTONE 2 By letter dated February 28, 1986, in response to the staff's letter dated .

October 31, 1985, you submitted an IST program for the safety-related Emergency Diesel Generator (EDG) auxiliary systems and requests for relief from certain testing requirements. Although we have not completed our detailed re/iew of #

your submittal, our preliminary review makes it clear to us that your expanded program increases the scope of inservice testing for the EDG auxiliary systems.

We have concluded that this upgrading of inservice testing for the EDG auxiliaries will further enhance safety.

Based on our preliminary review, we agree with the determination that it is impractical within limitations of the design for you to meet certain of the specified ASME Code requirements and that imposition of those requirements would result in hardships or unusual difficulties. Therefore, pursuant to 10 CFR 50.55a(g)(6)(i), we hereby grant the relief requested in your February 28, 1986 letter from the inservice testing requirements of the ASME Code until the staff has completed its detailed review or until 6 months from the date of

this letter, whichever comes first. We have concluded that the relief granted-neither significantly increases the probability or consequences of accidents previously considered nor significantly decreases safety margins and therefore does not involve a significant hazards consideration. Therefore, you are authorized and should proceed to implement your proposed program no later than April 30, 1986.

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 testing program for the EDG auxiliaries. Granting of this relief from ASME Code requirements should not be 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) issue final approval of your program (which may contain modifications resulting from ,

the staff's review); and (2) grant relief from any ASME Code ~ requirements that i are determined to be impractical for your facility for the duration of the inspection interval.
