South Korean research team evaluates pipe rupture risk in nuclear power plants using probabilistic analysis

Researchers from Seoul National University of Science and Technology in South Korea have recently proposed a sensitivity analysis method based on probabilistic fracture mechanics to evaluate the rupture frequency of main coolant piping systems in nuclear power plants. This method can analyze the impact of uncertainties and modeling assumptions on prediction results, helping engineers distinguish extremely low-probability events from relatively more likely failure scenarios. In nuclear power plants, the main coolant piping system plays a critical role in maintaining structural integrity under normal reactor operating conditions. A pipe rupture could trigger a loss-of-coolant accident, and therefore this system has long been included in the key scope of nuclear power plant safety design and assessment.
