Dear Experts,

I would like to get info on following scenario.

Design code : ASME Sec : VIII Div. I

RT requirement : RT1

Service : Not Sour / lethal /  cyclic etc (Sulfur recovery Incinerator package).

The vessel having set in type nozzle with full penetration groove. This nozzle to shell weld cannot be radio graphed (Not lip type).  Is it required to do UT of nozzle to shell weld (Category D) joints for this vessel  if RT is not possible ?.
 

Please see attached joint configuration.
