Electricity from a generator connected to Experimental Breeder Reactor I (EBR-I) flowed through them. This is considered an important milestone in Indian breeder reactor technology. A number of breeder reactor designs use liquid sodium as coolant. In July, the Senate voted against terminating the Clinch River Breeder Reactor Project. Hahn's goal was to build and demonstrate a homemade Breeder Reactor. This is the concept of the fast breeder reactor or FBR. There are two ways to configure a breeder reactor to do the required breeding. As a breeder reactor, it converts thorium into nuclear fuels. It can be made into fissile uranium-233 in a breeder reactor. It was the world's first breeder reactor. It was home of Experimental Breeder Reactor I, the world's first electricity-generating nuclear power plant. Construction started on the larger BN-800 fast breeder reactor in 1987. Oak Ridge investigated both ways to make a breeder for their molten salt breeder reactor. In principle, berkelium-249 can sustain a nuclear chain reaction in a fast breeder reactor. In a breeder reactor, the conversion ratio is higher than 1.
