TCarter Gentlemen:
file RE: THREE MILE ISLAND UNIT NO. 1
\\
By letters dated August 17 and September 30, 1977, you submitted a croposed
\\
i inservice inspection and testing progran description and requests for relief from selected ASME Code requirements pursuant to 10 CFR 50.55a(n).
Although we have not completed our detailed review of your submittals, our preliminary review inakes clear to us that your proposed program to impleneat 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 your detemination that it is impractical within the limitations of design, geometry and materials of construction of components, for you to ceet certain of the specified ASME Code requirements and that imoosition of those requirecents 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 detemined 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 Specitiutions are more restricti on January 2,1979, which is the date that *.he requirements of f
M'T f 10 CFR 50.55a(g) becoce effective for your facility.
1493 082 7910800 [gk
'g, 2-During the period between the date that the requirenents of 10 CF'l 50.55a(g) becone effective for your f acility and the date we coaalete our detailed review of your submittal you must coeply with both your existing Technical Specifications and your proposed inservice inspection and testing prograrr.
In the event conflicting requirements arise for sone components, you must comply with the more restrictive requirerents (e.g., shorter inspecticn intervals, increased nunoer of parameters measured).
In other words, the granting of this relief from ASME Code reouirements should not be interpreted to give you relief fron any of the requireinents in your existing Technical Specifications.
When our detailed review of your Aunust 17 and Septender 30, 1977 subnittals is complete we will:
(1) issue final approval of your program (which may contain modifications resulting from the staff's review), (2) grant relief fron any ASME Code requirements that are determined to 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 Federal Register Notice related to this action is enclosed.

The relief relates to the inservice inspection (testing) program for the Three ' tile Island !!uclear Station Unit fio.1 (the facility) located in Dauphin County, Pennsylvania.
The AS"E Code requirements are incorporated by refererce into the Commission's rules cna regulations in 10 CFR Part 50. The relief is effective as of its date of issuance.
This action provides relief from certain AS.YE Code Section XI inservice inspection and testina requirements determined to be imprac-tical for the facility, because compliance would result in hardships and unusual difficulties without a compensating increase in the level of quality and safety.
