This report contains the results of calculations for a resized nozzle on the D-Zero test cryostat. The nozzle neck in the inner vessel with be 6-inch schedule 10S pipe and 8-inch 10S will be used for the outer vessel. On top of the nozzle will be placed the D-Zero Endcap Calorimeter signal board feedthru dewar box. This box weighs approximately 250 lbs but the weight was conservatively taken to be 500 lbs. The allowable pressure from above does not exceed 15 psig per ASME, but it does exceed 7.5 psig required by CGA-341 therefore reinforcement is not required. Note that the reinforcement provided by the nozzle neck in combination with the excess shell thickness is probably sufficient to satisfy the ASME requirements
