O Westinghouse Electric Corporation Pensacola Plant
- Docket No. 99900104/80-01 NOIICE OF DEVIATION Based on the results of an NRC inspection conducted on April 21-25, 1980, it appeared that certain of your activities were not conducted in full compliance with NRC requirements as indicated below:
Criterion V of Appendix B to 10 CFR 50 states:
" Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, or a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings.
Instructions, procedures, or drawings shall include appropriate quantitative or qualitative accep-cance criteria for determining that important activities have been satisfactorily accomplished."
Deviations from these requirements are as follows:

A.
ASME Code Section IX, Article II, QW-282.4 states in part, " Essential Variables... Plasma Arc Welding. The WPS shall be set up as a new WPS, and shall be completely requalified, when any of the following changes are made.
(g) A change in the voltage beyond the range specified.
(1)... A decrease of 10 percent, or more, in the rate of flow of shielding gas or mixture."
4 WPS PAW-MA-385, revision 3, required the use of 14-18 volts and a shield-ing gas flow rate of 50 CFH.
Contrary to the above, che, inspector observed in-process hard facing weld metal overlay operations, using WPS PAW-MA-385 on Shop order PCZL 454, in which the following violations of essential variables a
occurred:
(1) Welding was being performed using 26 volts.
(2) The shielding gas flow rate was 45 CFH.
B.
Procedure DMP-15-4-5524, revision 4, requires the placement of two ther-mocouples (one each on the upper and lower flanges) during postweld heat treatment (PWHT) of pressurizer nozzles.
Contrary to the above, the PWRT chart recording dated April 12, 1980, for a pressurizer nozzle, shop order 174, serial number W664 A01, revealed just one thermocouple was used.
