How does the staff envision that the reliability and risk methods developed in its research will be used to supplement the deterministic licensing process?
The staff intends to provide one acceptable method that can be applied to current NRC guidance for using probabilistic risk assessment in risk-informing licensing decisions (Regulatory Guide 1.174, “An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis”). In addition, a task working group (TWG), consisting of various NRC staff members and industry participants, has been formed to identify and rsolve technical issues that will result in more efficient licensing of digital I&C systems for new reactor applications and for retrofits at operating reactors/facilities. What are the digital system modeling methods used in other industries—such as aerospace, defense, and telecommunications—and why does the staff think they may be adapted for use in nuclear power plants? Other industries have developed methods to model digital systems by using a number of methods, including fault trees, dynamic fault trees (used by the Nat
