Environmentally-Assisted Fatigue Management of PWR Pressurizer Using Nonlinear Strain-Based Analysis
Keyword(s):
This paper describes the techniques utilized to perform a nonlinear, strain-based, environmentally-assisted fatigue evaluation of a pressurizer vessel in a nuclear power plant. Significant differences between the strain-based and more traditional fatigue analysis results are demonstrated. This paper concludes that leveraging today’s computer power with the use of more detailed, nonlinear analysis is an effective tool for nuclear power plants to meet license renewal commitments related to the management of environmentally-assisted fatigue.
