Shoreham Nuclear Power Station - Unit No. 1 (V

i Docket No. 50-322

Dear Mr. Carlson:

My letter you, SNRC-332 of October 18, 1978, contained in part our response to NRC Finding 322/78-12-01, undersized welds on pipe spool slip-on flanges, reported in the enclosures to your letter of August 30, 1978.

This letter modifies portions of that response.

i My earlier letter indicated that, as a result of a sampling inspection, all accessible pipe spool slip-on flange j

welds would be reinspected, and that those found deficient would be repaired to meet ASME III requirements.

Subsequent evaluation l

of the sampling inspection results has revealed that the copper i

nickel and stainless steel slip-on flange welds are acceptable

{,

and that rejectable weld defects were identified only on Class 151 and Class 301 slip-on flange welds.

Accordingly, only Class 151 and i

l Class 301 slip-on flange welds will be 100% inspected, and those j

found deficient will be repaired to meet ASME III requirements.

?

~:

Full compliance is still expected by February 1, 1979.

Very truly yours, 7
