Dear Mr. Farrar:
SUBJECT:
ZION STATION, UNITS 1 AND 2 - INSERVICE INSPECTION AND TESTING PROGRAM - SECOND 10 YEAR INTERVAL By letters dated June 27, 1983, June 26, 1984, August 14, 1984 and June 17, 1986, Commonwealth Edison Company submitted a proposed inservice 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 review of your submittal, our preliminary review makes clear to us that your proposed program to implement those ASME Code requirements that you have found to be practical would increase the scope of inservice testing for your facility beyond that currently required by your Technical Specifications. We have concluded that this upgrading of your inservice 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 and construction 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 safety. Therefore, pursuant to 10 CFR 50.55afg)(6)(1),
we hereby grant relief until the staff has completed its detailed review or until June 31, 1987, whichever comes first, from those inservice testing requirements of the ASME Code that you have requested. Moreover, since the scope of the inservice 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 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).
861009037o 860930 PDR ADOCK 05000295 G
. 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.
In the event conflicting requirements arise for some components, you mut,t 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.
Sincerely,
% haa jgg t
