Work advances on X-energy’s TRISO fuel fabrication facility
Small modular reactor developer X-energy, together with its fuel-developing subsidiary TRISO-X, has selected Clark Construction Group to finish the building construction phase of its advanced nuclear fuel fabrication facility, known as TX-1, in Oak Ridge, Tenn. It will be the first of two Oak Ridge facilities built to manufacture the company’s TRISO fuel for use in its Xe-100 SMR. The initial deployment of the Xe-100 will be at Dow Chemical Company’s UCC Seadrift Operations manufacturing site on Texas’s Gulf Coast.

The production of defects by thermal neutrons in CdS results from the recoil of an energetic 114Cd nucleus. The recoil results from prompt emission of 9 MeV of gamma energy following thermal-neutron capture by 113Cd through the nuclear reaction: 113Cd + nth → (114Cd) → 114Cd + γ. The changes in the optical and electrical properties of CdS were measured to determine the effect of such recoils. A recombination center for the 7200A emission is produced and both the 4880A emission and edge emission are reduced. In addition, the conductivity of initially conducting CdS crystals is decreased by many orders of magnitude. The temperature dependence of the conductivity of thermal-neutron irradiated crystals indicates the production of a state about 0.5 eV below the conduction band.
