Title: Surge Nozzle NDE Specimen Mechanical Stress Improvement Analysis

Technical Report ·
DOI:https://doi.org/10.2172/1022430· OSTI ID:1022430

The purpose of this project was to perform a finite element analysis of a pressurized water reactor pressurizer surge nozzle mock-up to predict both the weld residual stresses created in its construction and the final stress state after the application of the Mechanical Stress Improvement Process (MSIP). Strain gages were applied to the inner diameter of the mock-up to record strain changes during the MSIP. These strain readings were used in an attempt to calculate the final stress state of the mock-up as well.
