Application of Margin-Based Methods to Assess System Health, INL/RPT-22-70361 | 274554 | | Health management of complex systems such as nuclear power plants is an essential task to guarantee system reliability. This task can be greatly enhanced by constantly monitoring asset status/performances, and processing such data (through anomaly detection, diagnostic, and prognostic computational algorithms) to identify asset degradation trends and faulty states. | Health management of complex systems such as nuclear power plants is an essential task to guarantee system reliability.

Risk-Informed Initiating Events Accident Response, INL/RPT-22-68669 | 37169 | | Opportunities exist to make plants’ regulatory compliance processes more efficient which can be done by decreasing reliance on deterministic and prescriptive approaches and expansion of the use of risk-informed and performance-based approaches to demonstrate reactor safety. In this report, we researched possibilities of economic benefits potentially available from the application of concepts associated with a modernized regulatory framework developed for advanced reactors to the existing light water reactors. As the result, we have identified multiple areas of existing plant operations where modernization of compliance activities can offer substantial economic benefits. Additional research is needed to demonstrate these expected benefits using case studies conducted in collaboration with utilities. | Opportunities exist to make plants’ regulatory compliance processes more efficient which can be done by decreasing reliance on deterministic and prescriptive approaches and expansion of the use of risk-informed and performance-based approaches to demonstrate reactor safety.
