Validated numerical analysis of residual stresses in Safety Relief Valve (SRV) nozzle mock-ups

► We present detail pass-by-pass simulations of the full manufacturing history of nozzle mock-ups. ► We show the importance of including the weld cap removal in the analysis. ► We show that the buttering process can be omitted in the analysis. ► We validate the current modelling procedure using the DHD and iDHD.
