January 3,1986 Docket No. 50-336 Mr. John F. Opeka, Senior Vice President Nuclear Engineering and Operations Northeast Nuclear Energy Company P. O. Box 270 Hartford, Connecticut 06141-0270

SUBJECT:

MILLSTONE UNIT 2 - INSERVICE INSPECTION AND TESTING PROGRAM - SECOND 10 YEAR INTERVAL By letter dated June 27, 1985 and supplemented on August 30, 1985 and December 16, 1985, you submitted a proposed inservice inspection and testing program description and requests for relief from selected ASME Code requirements pursuant to 10 CFR 50.55a(g). Although we have not completed our detailed j

review of your submittal, our prelininary review makes clear to us that your l

proposed program to implement those ASME Code requirements that you have found to be practical would increase the scope of inservice inspection and testing for your facility beyond that currently required by your Technical Specifications.

We have concluded that this upgrading of your inservice inspection and testing program will further enhance safety.

Based on our preliminary review, we agree with the 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 l

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)(1),

we hereby grant relief until the staff has completed its detailed review or until October 1,1986, whichever comes first, from those inservice inspection and testing requirements of the ASME Code that you have requested. There exists some ambiguity in the alternate testing inspection period proposed in your December 16, 1985 letter. Our interim relief is granted on the basis that one Main Feed System check valve (i.e., 2-FW-5A or 2-FW-58) is disassembled during each refueling outage to verify obturator freedom of movement. Should this inspection reveal that the disassembled valve's full-stroke capability is in question, then the remaining check valve is also to be disassembled and verified to operate properly prior to startup. 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 I

impracticality of selected ASME Code requirements, we have determined that t

the relief granted neither increases the probability or consequences of accidents previously.onsidered nor decreases safety margins and that, therefore, it does not involve a significant hazards consideration. Therefore, you are authorized to, and should proceed to, implement your proposed program (except where your current Technical Specifications are more restrictive).

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.

s Mr. John F. Opeka In the event conflicting requirements arise 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 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 are determined to be impractical for your facility for the duration of the inspection interval. These reviews are being conducted under our TAC number 59265.

Sincerely,

/S/
