How is the nozzle fillet radius calculated for WRC calculations?
On the Nozzle Properties, Local load tab, the program calculates the minimum fillet according to ASME UW-16.
The default radius is equal to Radius = Throat*cos(45°)/(1-cos(45°)
The user can input the radius value or Kn/Kb coefficients in the nozzle load tab:
