Shearon Harris Nuclear Power Plant Draft Safety Evaluation Report (DSER)
Materials Engineering Branch 0 en Item 36 (DSER Section 5.3.1.2 a es 5-12 and 5-19)
To demonstrate compliance with the beltline material test requirements of Paragraph III.C.2 of Appendix G, 10 CFR 50:
Indicate the post-weld heat treatment used in the fabrication of the beltline production and test welds.
Indicate the plates used to fabricate the test welds.
Indicate whether the test specimens for the beltline weld seams were removed from excess material in the vessel shell course following completion of the weld joint.
~Res esse The post weld heat treatment used in fabrication of the beltline production and test welds is as follows:
Production Weld Test Meld Unit 1
Unit 2 1150'F 10-1/4 Hr-'FC 1150'F 9 Hr-FC 1150'F 10 Hr-PC 1150'F 9-1/2 Hr-PC Plates used to fabricate test welds are as follows:
Unit 1 Plate B4197-2 and A9153-1 Unit 2 Plate B4197-1 and A9154-2 Test specimens for beltline weld seams were removed from a separate weldment since the same welding process was used for longitudinal and circumferential welds in the plates.
The same weld procedure was used in fabricating the production welds and test weld.
The following weld parameters were used to fabricate the welds.
Single Mire+
3/16" dia.
RACD INMM 550-650 Tandem Wire (head) 3/16" dia.
RACD INMM 650-750 (trail) 3/16" dia.
