Dear Sir,

thank you for your reply, but i have a doubt with refernce to the attachement CAESAR II App Guide. in which the nozzle is modeled as per WRC297 and the nozzle calculaiton is done at end of error checking, later in conclusoin page it is referred to the WRC107 to check the vessels stresses due to nozzle loads.

from your message i understand the same that if the nozzle is modeled as per WRC297, the WRC107 is not apllicable to the nozzle but not the vessel stress calcualtion right?

The WRC297 nozzle stiffness calculation is being done at end of error checking.. further to this do we required to run the WRC297 analysis which i found in the Analysis menu?.
