~1,gy3MERS February 19, 1991 Mr. David Williams Inspector General U.S. Nuclear Regulatory Commission Washington, D.C.
20555
Dear Mr. Williams:
I am making a formal allegation regarding the following information I have received.
I am sending it to you since it raises some disturbing questions about whether this information was ever reported to the NRC and if it was, whether appropriate actiod ves-ev.er taken.
This'tallegation~
is on the subject of Dravo piping Company, the same company which was recently discovered to have delivered substandard piping to Seabrook Station and other nuclear power plants.
Our inf ormant is a f ormer pullman-Higgins NDE inspector with ten years' experience in the field prior to his employment at Seabrook Station in about 1980.
Ile was told there were some problems with Dravo piping.
A weld inspector at the Dravo manufacturing facility in pennsylvania had falsified weld inspections while performing x-rays of flanges and piping.
The inspector had taken unclear, unacceptable x-rays.
Using a lead pencil, he falsified the x-ray results either by running the lead pencil around the inside of the hole of the pentrameter, thus enhancing the hole on the radiograph, or by drawing right on the film so it appeared that the hole was clear.
The pentrameter shows the clarity of the x-ray so the inspector can determine whether all defects are shown on the film.
There are three holes on the pentrameter, and depending on the particular requirement, the first, second, or third hole must be visible.
The informant recalls there was quite a bit of Dravo piping in Seabrook Station affected by these falsified x-rays, mostly f our and six inch piping on the nuclear side of the plant.
He was told the affected pipe was pulled and sent back or replaced.
