Wold details for the 7 DSC's with Carbon Steel Spacer Disks are shown on BGE-01 1000 Sh 1. TMs drewing shows two 3/8' partial penetration welds with 1/6' buildup.
Similarty, assemblies to the 2 stainless steel spacer disks have welds on top and bottom os shown on drawing BCE-01 1001 Sh 1. This drawing shows a 1/2' partial penetration weld with 1/8' buildup at the top and a 1/8' fillet at the bottom. These weld details aneurs lood transfer capabliity of the joints.
Hand oolculations have confirmed the weld adequacy of the 7 assemblies with carbon steel spacer disks. Computer onelyses are being performed to show adequacy of the 2 assemblies with the stainless steel spacer disks.
