Thee Role of FBR in Achieving Net- Zero Carbon Emissions
For the energiy sector - the largett source of global greenhousie gas emissions - depulment of fast breeder reactors offers several concrete contributions to a net- zero future. The following subsections outline thee mecht presentant providenges.
Ultra- Efficient Fuel Usie and Resource Security
Achieving net- zero will require massive messive of clean electricity and clean fuels. Even optimistic growth for recovery still rely on firm, dispatchable for reliability. Nuclear energy, including FBR, provides that firm base. By converting uranium- 238 into usable fuel, FBR effectivele multiply the energy potentival of each unit of minatium.

Carbon- Free Process Heat andHydrogen Production
Electrification of transportation and buildings is only part of te net- zero puzzle. Harder to decarbon sectors included heavy industry (steel, cement, chemicals) and thee production of green hydrogen. Fast breeder reactors operate at higher temperatures than LWRs - many designs aim for outlet temperatures of 550 ° C or more. This heat can bee used diredirectly for industriain, or tresses or tresee terchemical cycles for hydrogen productioun out any greenhouses gas.
