APPENDIX A Washington Public Power Supply System P. O. Box 468 Richland, Washington 99352 Docket Nos. 50-508 & 50-509 NOTICE OF VIOLATION Based on the results of an NRC inspection conducted during the period of November 6-9, 1979, it appears that certain of your activities we're not conducted in full compliance with conditions of your NRC Facility Licenses Nos. CPPR-154 (Unit 3) and CPPR-155 (Unit 5) as indicated below.
A.
10CFR 50, Appendix B. Criterion V, as implemented by Section 17.4.5 of the Quality Assurance Program documented in the approved PSAR deviation 18-WP, states, in part, that " Activities affecting quality...shall be accomplished in accordance with... instructions, procedures or drawings."
Chicago Bridge and Iron Special Instruction No. SI-2, Rev. 0 (Entitled
" Field 4-Hour Coated Weld Electrode Control") requires that weld elec-l trode being retgrned by a welder..." shall be placed in a baking even g
and hald at 250 F (200 F minimum) for eight (8) hours prior to reissu-ance This oven shall be marked "8-hour Holding Oven...".
Contrary to the above, on November 7, 1979, the NRC inspector observed that welding electrodes were returned by a welder and placed in Unit 3 electrode oven No. B, labeled " Issue 0ven", and other electrodes subse-quer tly issued from the same oven. The oven immediately below oven No. B, was labeled Oven No. C " Hold Oven", and was not utilized during the transactions.
This is an infraction and is applicable to Unit 3.
B.
10CFR 50, Appendix B, Criterion V, as implemented by Section 17.4.5 of the Quality Assurance Program documented in the approved PSAR deviation 18-WP, states, in part, that " Activities affecting quality...shall be accomplished in accordance with... instructions, procedures or drawings."
Chicago Bridge and Iron General Welding Procedure No. GWPS-SMA-74-3431, revision 1, states that "The edges or surfaces of the pieces to be i
joined by welding shall be... cleaned of oil..."
Contrary to this requirement, on November 7,1979, the NRC inspector-observed that the welder performing welding on Unit 5 containment vessel weld No. 53B was welding through an area (approximately 12 inches in diameter at the 15 ft. mark) which was contaminated with oil.
This is an infraction and is applicable to Unit 5.
8002 1300t5
t C.
10CFR 50, Appendix B, Criterion IX, as _ implemented by Section 17.4.9 of the Quality Assurance Program documented in the approved PSAR deviation 18-WP, states, in part, that "Special processes, including welding...are i
controlled and accomplished...usino qualified procedures...in accordance with applicable codes, standards, specifications, criteria and other special requirements."
The ASME Boiler and Pressure Vessel Code,Section IX, paragraph QW-251.2 requires that " Essential Variables are those in which a change...is con-sidered to effect the mechanical properties of the weldment/ and shall require requalification of the WPS.
Supplementary Essential Variables L
are required for metals for which other sections of the Code specify notch-toughness tests." The notch-toughness requirement for containment-vessel material is specified in Section 3.8 of the PSAR.
Paragraph QW-255.1(a) lists paragraph QW-409.1 as a Supplementary Essential Variable.
Paragraph QW-409.1 specifies that variable, in part, as"...a change in the ranges of amperage, voltage or travel speed."
Contrary to the above, Chicago Bridge and Iron Welding Procedure Spec-i ification No. E7018/74-3431, Rev. 2 was not requalified for the change in amperage ranges provided in the procedure.
For example the WPS allows a current range of 100-180 amps for 1/8" rod in all positions, and 140-225 amps for 5/32" rod in all positions, whereas, related welding Procedure Qualification Records Nos. 2631 and 3250 reflect a maximum current of 160 amps for 1/8" rod in overhead and down flat positions, and a maximum current of 190 amps for 5/32" rod in averhead and down flat positions.
This is an infraction and is applicable to Units 3 and 5.
