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.

Half-lives have been measured by direct decay for 18 radionuclides. The method of least squares was used to obtain the best straight-line fit to the data. The observed half-lives are 87.9 ± 0.3 d for S35, 52.7 ± 0.5 d for Sr89, 13.6 ± 0.3 y for Nb93m, 35.8 ± 0.5 d for Nb95, 65.5 ± 0.2 d for Zr95, 39.5 ± 0.3 d for Ru103, 368.0 ± 1.8 d for Ru106, 13.6 ± 0.2 y for Cd113, 76.3 ± 6.6 y for Sn121, 2.71 ± 0.02 y for Sb125, 1.99 ± 0.02 y for Cs134, 283.8 ± 0.6 d for Ce144, 2.60 ± 0.02 y for Pm147, 87 ± 9 y for Sm151, 134.2 ± 0.8 d for Tm170, 700± 5 d for Tm171, 3.68 ± 0.05 y for Tl204, and 164.4 ± 0.4 d for Cm242. These data are compared with current literature values, and average values of the existing determinations are given.
