Risk-Informed Initiating Events Accident Response, INL/RPT-22-686693716900 - Risk-Informed Initiatives and ApplicationsOpportunities 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.

Dynamic and Classical PRA Coupling using EMRALD and SAPHIRE, INL/RPT-22-7042427454806 - Enhanced Fire Probabilistic Risk AssessmentBoth classical and dynamic probabilistic risk assessment tools are valuable for different kinds of analysis. Typically, one or the other is used depending on the scenario and the limitations of the tool. Often, the results of one are used as a parameter in the other. This research looks at the possible methods for combining classical and dynamic analyses by coupling EMRALD and SAPHIRE. This was initial exploratory research to evaluate methods and determine how the tools could be coupled. A short background of SAPHIRE and its solving methods is provided, along with information on EMRALD to help understand the correlation between the two types of modeling.Both classical and dynamic probabilistic risk assessment tools are valuable for different kinds of analysis.
