February 6, 1980 Docket No. 50-338 Mr. W. L. Proffitt Senior Vice President - Power Operations Virginia Electric & Power Company P. O. Box 26666 Richmond, Virginia 23261
Dear Mr. Proffitt:
SUBJECT:
RELIEF FROM THE REQUIREMENTS OF THE ASME BOILER AND PRESSURE VESSEL CODE SECTION XI - NORTH ANNA POWER STATION, UNIT NO.1 By letters dated August 10, 1977 and September 29, 1977, you submitted a proposed inservice testing program for pumps and valves and requested relief from selected ASME Code requirements pursuant to 10 CFR 50.55a(g).
Our letter dated October 17, 1977, stated that your proposed program was acceptable and granted relief from certain of the specified ASME Code requirements for a 20 month period following the start of facility comercial operation. Also', by letters dated May 4,1979 and September 4, 1979 you comitted to further requirements as specified by the NRC staff regarding your inservice testing program. By letters dated November 2, 1978 and January 15, 1978, you proposed revisions to your inservice testing program for pumps and valves and requested that relief for the
-inservice testing program be extended beyond February 6', 1980 (20 month period from comercial operation).
Based on our preliminary review, we agree with your 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 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)(i), we hereby grant relief, on an interim basis, pending completion of our detailed review, from those inservice testing requirements of the ASME Code that you have requested. Moreover, since the scope _ of the' inservice inspection and testing will be increased tf your program, and the granting of this relief is based only on thP impracticality of selected ASME Code requirements, we have detera11ned 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 program.
8063190
Mr. W. L. - Proffitt. February 6,1980 In the event conflicting requirements arise for some components, you must
~
comply with the more conservative requirements.
In other words, the granting of this relief from ASME Code requirements should not be inter-preted to give you relief from any of the requirements in your existing Technical Specifications.
When our detailed review of your submittals dated November 2, 1978 and January 15, 1980 are complete, we will:
(1) issue final approval of your program (which may contain modifications resulting from the staff's final review), (2) grant relief from 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.
