RE: R.ANCHO SECO NUCLEAR GENERATING STATION 5y letter da ed July 18, 1979, you submitted a preccsed inservice inspection and testing :rogram descript"on and a recuest for relief from selected ASME Ccde recuirements pursuant ta 10 CFR 50.55a(g). Although we have not ccm-
- le:ac cur catailed review of your submittal, our preliminary review makes
- l ear to us that your preposed program to implement those ASME Code require-
- en's that you have found to be practical would increase the sccce of inservice ins:ection and testing fcr your facility beyond that currently required by your Te:hnical Scecifications. We have concluced that tnis ucgrading of your inservice ir.specticn and testing program will further enhance safety.
5ased On our preliminary review, we agree with your determination that it is i: practical within the limitations of design, geometry and materials of Ocns ructicn of components, for you to meet certain of the specified ASME Ocde recuirements and that imecsition of those requirements would result in carcships or unusual difficulties without a ccm:ensating increase in the level cf quality or safety. Therefore, pursuant to 10 CFR 50.55a{g)(6)(1),
e r.ereby gran relief, en an interim basis, pencing ccoletion of our
- e* ailec review, frem these inservice inspection anc testing requirements of :ne ASME Code that you have requested as modified by NRC staff comments on your prcposal made during the working session held with your staff en Oc ::er 3 and 4,1979. Moreover, since the scoce of the inservice inscection and testing will be increased by your procosed crogram, and the granting of this relief is based only on the fmoracticality of selected ASME Code e-:uirements, we have determined that the relief granted neither increases
.7e prcbability or consequences of accicents p'eviously c:nsidered nor decreases safety margins and that, tnerefore, it does not involve a signifi-can: hazards consideration. Therefore, ycu are aut cri:ed to, and shcuid
- rceeed to, im lement your proposed program as :necified by NRC staff cercents ace curing':ne working session (exceo: where your curren: Technical Specifications are cre restri::ive).

Within 30 days of receipt of this letter, ycu sh:uld su:mit to the."RC documentation of the mcdifications ycu will be ic:lementir.; with your pr: posed program based on the comments received fr m the staff during tne working session on October 3 and 4,1979.
Ouring the :eriod between the date that the requirements of 10 CFR 50.55a(g) become effective for your facility and the date we c:mplete our detailed review of your submittal you must ccmply with both ycur existing Technical 5:ecifications and your proposed inservice inspection and testing program.
In the event conflicting requirements arise for scme com;onents, you m ;;
comoly with tne more restrictive requirements (e.g., sncrter 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 ' rom any of the requirements in ycur existing Technical Specifications.
When our detailed review of your July 18, 1979 submittal is complete, we will:
(1) issue final approval of your program '.whicn may contain modifica-tions resulting from the staff's final review),,'2) gran; relief from any ASME Code recuirements that are determined to be impractical for your facility for the duration of the inspection interval and,'3) issue a:oropriate changes to your Technical Specifications.
A cocy of the Federal Recister Notice related to this action is enclosed.
Sincerely,
@M Y h-M /4 V
