Dear Mr Low:

in accordance with 10CFR50.55(e), this is to give you preliminary notice of a matter that may be a reportable deficiency pending the results of a full investigation now under way. -

As I advised the Regional Director by telephone on June 6, 1972, that morning we learned that some X-ray film of pipe welds had been marked with a pencil in such a way as to obscure the true penetrameter reading. Through professionally-conducted interrogation of personnel, we have determined that the marking was done by one individual, and no others. We are undertaking a program of investi-gation to re-examine all film, to cleanse film where marks are found under procedures developed by the film manuf acturer, and to repeat NDT procedures in such Instances where valid penetrameter readings may not be obtainable. Our program and all procedures thereunder will be fully documented and a report prepared of results. We cannot give you a schedule of completion until we are further into the program, but we will keep your inspector fully advised of our progress.

Yours very truly, 1
