Risk-Informed Safety Margin Characterization (RISMC): Integrated Treatment of Aleatory and Epistemic Uncertainty in Safety Analysis
The concept of “margin” has a long history in nuclear licensing and in the codification of good engineering practices. However, some traditional applications of “margin” have been carried out for surrogate scenarios (such as design basis scenarios), without regard to the actual frequencies of those scenarios, and have been carried out in a systematically conservative fashion. In the RISMC proje...

متن کاملModeling of a Flooding Induced Station Blackout for a Pressurized Water Reactor Using the RISMC Toolkit
In the Risk-Informed Safety Margin Characterization (RISMC) approach we want to understand not just the frequency of an event like core damage, but how close we are (or are not) to key safety-related events and how might we increase our safety margins. The RISMC Pathway uses the probabilistic margin approach to quantify impacts to reliability and safety by coupling both probabilistic (via stoch...
متن کاملGeneration and Use of Reduced Order Models for Safety Applications Using RAVEN
INTRODUCTION The Risk-Informed Safety Margin Characterization (RISMC) [1] Pathway (as part of the Light Water Sustainability (LWRS) Program [2]) aims to develop simulation-based tools and methods to assess risks for existing Nuclear Power Plants (NPPs). This Pathway, by developing new methods, is extending the Probabilistic Risk assessment (PRA) stateof-the-practice methods [3] which have been ...
