Applying User-Centered Design Principles to Build Tools for Nuclear Regulatory Review Efficiency
DescriptionTo support safe and efficient nuclear oversight, the United States Nuclear Regulatory Commission (NRC) human factors team developed a new digital tool that helps technical reviewers quickly locate relevant case studies when evaluating proposed power reactor licensing amendments. Using user-centered design principles, the team created an interactive case-study repository to improve the speed and consistency of “precedence reviews,” which identify past licensing decisions that relate to current applications. Built with reviewer input and refined through multiple development cycles, the tool was designed to be intuitive and practical—saving reviewers significant time and effort. Early feedback has been highly positive, and the tool is expected to reduce hundreds of hours of manual document search. This project highlights how human factors methods can improve regulatory workflows and lays the groundwork for future expansions using AI and data science to further support nuclear safety and efficiency.
