What will be the final product in terms of integrating these improved methods for diversity and defense-in-depth analysis into regulatory guidance and acceptance criteria for licensing activities?
The Diversity and Defense-in-Depth (D3) research project will develop combinations of diversity attributes and associated criteria that provide acceptable D3 strategies for addressing common-mode failure vulnerabilities in digital safety system designs. The information obtained from this research project will be used to develop a revision to NUREG/CR-6303, “Method for Performing Diversity and Defense-in-Depth Analyses of Reactor Protection Systems,” or a new NUREG that will provide enhanced technical guidance to the staff on appropriate common-mode failure mitigation measures using diversity attributes and criteria. It will also be used to develop regulatory acceptance criteria that will complement existing NRC regulatory processes (i.e., BTP-19, “Guidance on Evaluation of Defense-in-Depth and Diversity (D3) of Digital I&C”) for confirming appropriate implementation of common-mode failure mitigation strategies. A regulatory guide could ultimately result from this project.
