A Note on Probability Quantification for Protective System Efficacy Analysis: Stochastic Dynamics, Information Flow, and Initiating Event Arrival Times
Martin Wortman, Ernest Kee, Pranav Kannan
Probability Quantification (PQ) predictions of the efficacy of safety-critical protective systems is challenging. Yet, the popularity of PQ methodologies (e.g., Probabilistic Risk…
Is Core Damage Frequency an Informative Risk Metric?
Martin A. Wortman, Ernest J. L. Kee, Pranav Kannan
Core Damage Frequency (CDF) is a risk metric often employed by nuclear regulatory bodies worldwide. Numerical values for this metric are required by U.S. regulators, prior to react…
Safety-Critical Protective Systems and Margins of Safety
Martin Wortman, Ernest Kee, Pranav Kannan
The design and operation of protective systems is an essential engineering responsibility. Ensuring public safety, while essential, must be accomplished at a feasible cost and with…
Characterizing the Probability Law on Time Until Core Damage With PRA
Martin Wortman, Ernest Kee, Paul Nelson
Certain modeling assumptions underlying Probabilistic Risk Assessment (PRA) allow a simple computation of core damage frequency (CDF). These assumptions also guarantee that the tim…
