Nuclear fuel pellet
(1979 document photograph)
Nuclear fuel pellets. Gloved hands holding life- sized models of nuclear fuel pellets with their injection rod. Each pellet can produce the same amount of energy as 3 tons of coal. The pellets are designed for use in fast breeder nuclear reactors. These use fuel containing fissile uranium and plutonium, surrounded by a core of non-fissile uranium-238. During the reaction, neutrons are formed that collide with the U-238 to form fissile plutonium-239. The reaction generates more plutonium than it consumes. Photographed in 1979 at the Fast Flux Test Facility during research into fast breeder reactor fuels, USA.
