Mr. J. P. O'Reilly May 13, 1979 Attachment Duke Power Company McGuire Nuclear Station Response to IE Bulletin No. 79-03 1.) It has been determined that 2260 feet of ASME SA-312 welded pipe manufactured by Youngstown Welding And Engineering Company have been received at McGuire Nuclear Station. Some of the subject piping is in use or planned for use in safety-related systems.

2.) The application of the subject piping in safety-related systems at McGuire is not outlined in this respone since this piping has been given sufficient NDE using the liquid penetrant method and found acceptable as described in 3 below.

3.) ASME Code,Section III, Paragraph NC 2550 allows NDE by surf ace er volumetric examination. In order to meet this ASME Code requirement Duke required that all the subject piping be given a surface examination using the liquid penetrant method which was performed by Youngstown.

Duke representatives have inspected the Youngstown shops, reviewed Younstown's Method of liquid penetrant examination, and determined that their method meets the requirements of the ASME Code. The subject pipe has also passed a shop hydrostratic test and will receive a field hydrostratic test. No additional inspections are planned at this time.
