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.

A combination of relative reactivity measurements and absolute counting techniques has been applied to determine the epicadmium capture-to-fission ratio for 235U. Significant features of this procedure are its requirement of only a moderate neutron flux, the application of 252Cf and manganese to measure the relative importance of fission and absorbed neutrons, and the use of methods that differ from those applied in the high fluence procedures for α measurements. The resulting value of 0.519 ± 0.023, for infinite sample dilution, l/E spectrum, and 0.5-eV low-energy cutoff, is in good agreement with recent results from high fluence irradiations and differential cross-section data.
