Summary

Requires the Secretary to run civilian nuclear programs so advanced nuclear reactors move toward being sold and used commercially. It also lets the Secretary support work to make those reactors available sooner, including ones with standardized designs or passive safety features. Key words: "advanced nuclear reactor technologies" includes near‑term advanced light water reactors (for example mid‑sized units with passive safety) and other types that may need prototype tests before mid‑ or long‑term commercial use (for example high‑temperature gas‑cooled and liquid‑metal reactors); "Commission" means the Nuclear Regulatory Commission; "standardized design" is a design used at multiple units or sites; "certification" means the Commission’s approval of a standardized design.
