Mr. C. W. Fay, Vice President '
Nuclear Power Department Wisconsin Electric Power Company 231 West Michigan Street Room 308 Milwaukee, Wisconsin 53201
Dear Mr. Fay:
We have received your July 6, 1984 request for relief from the requirements of ASME Code Section XI 2nd ten year interval Inservice Inspection Require-ments for Point Beach Units 1 and 2.
These requests are under review.
Your July 6 letter also mentioned several areas associated with previously granted relief for Point Beach Units 1 and 2 for which you requested clari-fication or correction.
The first item of your concern covers our March 29, 1984' relief from the ASME Code requirement to perform surface examinations on three piping-to-penetra-tion cap welds in the auxiliary coolant and safety injection systems.
Relief was granted provided that the first weld in the process pipe outside contain-ment be subject to the recuired ASME Code examination.
You have subsequently detennined that the buriec welds inside the penetration are shop welds and that only some of the first welds outside containment were shop welds while others were field welds.
You have stated that the shop welds outside containment will more closely match the buried welds in terms of welding process and manufac-j turing conditions than would field welds; therefore, you feel that inspection i
of the first shop w(eld outside containment is more appropriate than inspection I
of the first weld since some first welds vould be field welds) and intend to meet the conditions of the granted relief ~ by inspecting the first shop weld out-side containment.
The NRC staff's )urpose in conditioning the granted relief was to provide assurance that t1e integrity of the inaccessible welds would be maintained to the extent practicable. The staff feels that inspection of the first weld out-side containment provides this assurance.
Tho staff is more concer.1cd with the location of the weld than its type.
Therefore, the staff disagrees with your position to inspect the first shop weld outside containment to meet the con-ditions of this granted relief.
Secondly, with regard to your January 13, 1983 requested relief RR-1-9 for inspection of Unit 1 safety injection reducer-to-safe end welds, failure to include this relief in our March 29, 1984 letter was an oversight on our part.
The relief request and its evaluation are included as Enclosure 1 to 4
this letter.

. Mr. C. W. Fay,
With regard to the correct designator for the weld identified as AC-10-RHR-1006-25 in relief request RR-1-5 of August 20, 1982 for Point. Beach Unit 1, we have reviewed the associated isometric drawings included in the August 20, 1982 relief request and agree that the correct designator for this weld is AC-10-RHR-1006-8. We consider this to be a typographical error not requiring further review.
Your interpretation of the visual inspection requirements for Point Beach Units 1 and 2 reactor vessel interior surfaces once every three years is correct.
That is, during a nonnal refueling only those areas which are accessible need be visually inspected. However, if, during an outage other than that nonnally scheduled for this inspection, the fuel is completely removed and other interior surfaces of the reactor vessel become accessible, we expect the visual examina-tion of the reactor vessel which had not been conducted during the previous in-spection to be performed.
Sincerely, p.,w [/
