SUBJECT:
POTENTIAL WELDING.DEFICIENCIES IN TANKS fABRICATED BY GRAVER
, TAiiK AND MANUFACTURING COMPANY You were informed by the NRC resident inspector on ilune 25, 1980 of potential welding defi<;iencies in tanks fabricated by Graver Tank and Manufacturing Co. that could *possibly*result *in *los*s of piping integrity at the pipe to tank connection during ASME Service. Level O loading conditions (e.* g. ~
seismic).* Welds in tanks were found at the Beaver Valley plarit which!>,
at the pipe to tank connection, \\*Jere not.in accordance with drawings and,
- at seam locations, contafoed unacceptable discpntinuities *. Quality. assurance records stated the welds were i.n accordance with the drawings and.of acceptable quality.
You are requested to determine if the*weldments in safety-related tanks at Salem Unit No. l fabricated by Graver Tank meet design specifications and fabrication requirements.
- Verificatfon of weld type *(i.e., seal or
- full penetration) and soundness must be done by independent nondestructive inspection and review or available construction radiographs; not through reliance on Graver inspection records.
Should NOE of the pipe connections.. *
- be impractical during plant operation, the* inspections may be. deferred,--~
to a sche~uled t:"efuelin~ ?u~age if the ~ipin~J ir.tegri~y-can be demonstrated by ana1ys1s assuming a J0111"t conf1gurat1on such as that* labeled 11as found 11 in Enclosure l or there is evidence of independent inspections of work __ in progress by the licensee during the-fabrication of the tank.
If w~lds are found which do not meet design specifications or fabrication requirements~
describe the corrective actions.that will be taken.
.Thfs informatfon is requested under the provisions of 10 CFR 50.54(f)..
Accordingly~ you are requested to provide within twenty (20} *days of the t
