$lh NOTICE OF DEVIATION Docket No. 50-454 Commonwealth Edison Docket No. 50-455 Corpany Based on the inspection conducted on October 31 - November 2, 1978, certain of your activities were not in accordance it appears that with commitments, codes, standards, guides or accept able practices,
as noted below.
Byron /Braidwood PSAR, Table 3.2-2 committed to the requirements of ASME B6PV Code,Section III for the design and fabrication of piping.
ASME B&PV Code,Section III requires that welding be performed in accordance with ASML BEPV Code,Section IX.
1974 Edition,Section III (including 1975 ASME, B6PV Cede, Summer Addenda), Tables NC-2331-1 and ND2331(a)-1 requires a.
specimens for material thickness the Charpy V Notch (C,#) inclusive to have a lateral expansion test over 1 1/2" to 2 1/2" value of 40 mils.
above, on November 2, 1978, the inspector Contary to a.
coupon used in qualifying Hunter established that the test Corporation Welding Procedure Specification (WPS) No. HC-WPS-5 was 2" thick and Calumet Associates Report No. C942-2 indi-cated that C test specimens No. 942-2B and No. 942-2C, taken from the heaE affected rone has a lateral expansion value of 38 mils and 36 mils respectively.
ASME, B6PV Code, 1974 Edition,Section IX (including 1975 Surrer Addenda) Paragraph QW-409.1, states, that "A change 1.
or polarity, or an increase in the in the type of current amperage or voltage" and Table QW-253 lists paragraph QW-409.1 as a Supplementary Essential Variables.
Hunter Corporation WPS No. HC-UPS-5, page 14, states the following:
