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.

Dose as a function of depth in tissue has been calculated for the case of solar-flare protons incident isotropically on slab shields followed by tissue slabs. The flare used has a spectrum that is exponential in rigidity with a characteristic rigidity P0 of 80 MV. Only incident protons with energies between 0 and 400 MeV are considered. Slab thicknesses of 4 and 20 g/cm2 of aluminum are considered and a tissue thickness of 30 cm is used. In general, it is found that the secondary contribution to the dose is small unless thick shields are considered. In particular, the secondary neutrons from flare protons with energy of less than 50 MeV do not contribute appreciably to the dose in the cases considered here.
