Special Topics for Risk Assessment in Event Evaluation

Course Topics

This course covers several special topic areas that need to be addressed when performing a probabilistic risk assessment (PRA) approach of event evaluation. The special topics areas include non-recovery events, common cause failures, human reliability analysis, initiating events, and general basic event modifications (i.e., setting events to failed, successful, True house event, and False house event). Risk metrics for initiating event and condition assessments will be presented to determine the risk significance level of an event evaluation. Conditional core damage probability and incremental core damage probability calculations will be discussed and how these risk measures can be calculated through the use of PRA software tools such as the Systems Analysis Programs for Hands-on Integrated Reliability Evaluation (SAPHIRE) program.

Some benefits

You will receive training on how adjustments can be made to a PRA model to calculate various risk metrics that can be evaluated to determine the risk significance of an event evaluation. This course will cover adjustments to the PRA model that should be considered when performing an event evaluation. The PRA software tool SAPHIRE will be used to demonstrate the adjustments and then the quantified risk metrics that can be used for risk significance determination of the event being assessed.

Why You Should Attend

Enhance your knowledge on the adjustments that should be considered for non-recovery events, common cause failures, human error events, initiating events, and general basic events during an event evaluation. Gain an understanding of the adjustments that may need to be done and then how the PRA model may be quantified to obtain risk metrics, such as conditional core damage probability and incremental core damage probability, for assessing the risk significance of event evaluation.
