Summary

Requires the Secretary to run civilian nuclear programs so advanced nuclear reactors can become commercially available and to support work that speeds their availability, including designs that are standardized or that use passive safety features. Defines key terms: "advanced nuclear reactor technologies" covers advanced light-water reactors (like mid-sized, passive-safety units that could be available soon) and other types (such as high-temperature gas-cooled and liquid-metal reactors) that may need prototype tests before mid- or long-term commercial use, all for generating commercial electric power from nuclear fission. "Commission" means the Nuclear Regulatory Commission. "Standardized design" is a design used at many units or sites. "Certification" means the Commission’s approval of such a design.

(a)The purposes of this part are—
(1)to require the Secretary to carry out civilian nuclear programs in a way that will lead toward the commercial availability of advanced nuclear reactor technologies; and
(2)to authorize such activities to further the timely availability of advanced nuclear reactor technologies, including technologies that utilize standardized designs or exhibit passive safety features.
(b)For purposes of this part—
(1)the term “advanced nuclear reactor technologies” means—
(A)advanced light water reactors that may be commercially available in the near-term, including but not limited to mid-sized reactors with passive safety features for the generation of commercial electric power from nuclear fission; and
(B)other advanced nuclear reactor technologies that may require prototype demonstration prior to commercial availability in the mid- or long-term, including but not limited to high-temperature, gas-cooled reactors and liquid metal reactors, for the generation of commercial electric power from nuclear fission;
(2)the term “Commission” means the Nuclear Regulatory Commission;
(3)the term “standardized design” means a design for a nuclear power plant that may be utilized for a multiple number of units or a multiple number of sites; and
(4)the term “certification” means approval by the Commission of a standardized design.
