; (2) many domestic advanced nuclear power industry participants require access to high-assay, low-enriched uranium fuel for— (A) operation of demonstration reactors; and (B) initial fuel testing; (C) commercial operation of advanced nuclear reactors; (3) as of the date of enactment of this Act, no domestic uranium enrichment or fuel fabrication capability exists for uranium fuel enriched to greater than 5 weight percent of the uranium-235 isotope; (4) a healthy commercial nuclear fuel cycle capable of providing higher levels of enriched uranium would benefit— (A) the relevant national security functions of the National Nuclear Security Administration; and (B) the domestic advanced nuclear industry of the United States; and (5) making limited quantities of high-assay, low-enriched uranium available from Department of Energy stockpiles of uranium would allow for initial fuel testing and demonstration of advanced nuclear reactor concepts, accelerating— (A) the path to market of those concepts; and (B) the development of— (i) a market for advanced nuclear reactors; and (ii) a resulting growing commercial nuclear fuel cycle capability. (b) Nuclear reactor demonstration project (1) In general Subtitle E of title IX of the Energy Policy Act of 2005 ( 42 U.S.C. 16271 et seq.) is amended by adding at the end the following: 959A. Advanced nuclear reactor research and development goals (a) Definitions In this section: (1) Advanced nuclear reactor The term advanced nuclear reactor means— (A) a nuclear fission reactor, including a prototype plant (as defined in sections 50.2 and 52.1 of title 10, Code of Federal Regulations (or successor regulations)), with significant improvements compared to the most recent generation of fission reactors, including improvements such as— (i) additional inherent safety features; (ii) lower waste yields; (iii) improved fuel performance; (iv) increased tolerance to loss of fuel cooling; (v) enhanced reliability; (vi) increased proliferation resistance; (vii) increased thermal efficiency
