Effect of Main Bolt Break on Seal Performance, Stress and Fatigue of Reactor Pressure Vessel

  • Publish Date: 2020-09-27
  • Base on the mechanics theory and numerical simulation technique, a method to analyze the effect of the main bolt break on the stress, fatigue and seal is studied in this paper, and is adopted to evaluate and analyze the fracture influence of main bolt. The results show that this method is applicable for the analysis of the RPV safety performance induced by one bolt break or several bolts break accident, and for the determination if the nuclear reactor can be operated when similar problems occur.
