Particulars of the Behavior Under Irradiation of Dispersion Fuel Elements with the Uranium Dioxide + Aluminum Alloy Fuel Composition

  • Published:
Atomic Energy Aims and scope

A fuel with the uranium dioxide + aluminum alloy composition was developed for fuel elements to be used in floating power-generating units and small nuclear power plants. Designs, fabrication technologies, and methods of monitoring cermet fuel elements of different standard sizes with an aluminum matrix and cladding comprised of zirconium alloys were developed at the Bochvar All-Russia Research Institute for Inorganic Materials. A complex of pre-reactor and reactor tests and post-reactor studies of fuel elements was conducted; it was shown that cermet fuel elements are promising. The particulars of the behavior under irradiation of fuel elements with the uranium dioxide + aluminum alloy fuel composition were determined.
