Separately proposed $750 million in new Title 17 credit subsidy for small modular and advanced reactor construction.

Requested $1.59 billion for DOE's Office of Nuclear Energy (about 10% below FY2024 appropriation), including $188 million for near-term HALEU supply, $694.2 million for reactor/fuel R&D, and $142.5 million for the Advanced Reactor Demonstration Program.

Requested more than $1.56 billion for DOE's Office of Nuclear Energy, including over $660 million for R&D supporting the existing fleet, advanced reactor deployment, and fuel cycle gaps. Requested $1.006 billion for the NRC, up 6.7% from FY2023 enacted.

Requested $1.7 billion for DOE's Office of Nuclear Energy, one of the highest asks ever for the office. Requested $929.2 million for the NRC (up $41.5 million from FY2022), including $490.7 million for reactor safety and $23.8 million for advanced reactor technology review.

First Biden-administration budget. Requested a then-record $1.85 billion for DOE's Office of Nuclear Energy (up more than 50% from the FY2021 request), including over $370 million for the Advanced Reactor Demonstration Program and $145 million for the Versatile Test Reactor.
