Miniature Uranium Fuel Plates Cooled by Liquid Helium for Irradiation Damage Studies
The low-temperature irradiation facility (LTIF) located at the bulk shielding reactor in Oak Ridge National Laboratory was designed and has been operated for several years for the study of thermal neutron damage in metals at low temperatures. The highly thermalized neutron flux is obtained by interposing tanks of heavy water between a face of the reactor (swimming-pool type) and the irradiation cryostat. A schematic diagram of the irradiation portion of the cryostat is given in Fig. 1. This design is improved over earlier published versions [1,2].
