Framatome, Ultra Safe partner to manufacture TRISO and FCM fuel
Framatome and Ultra Safe Nuclear announced on January 26 that they intend to form a joint venture to manufacture commercial quantities of tristructural isotropic (TRISO) particles and Ultra Safe’s proprietary fully ceramic microencapsulated (FCM) fuel.
The companies have signed a nonbinding agreement to integrate their resources to bring commercially viable, fourth-generation nuclear fuel to market for Ultra Safe’s micro-modular reactor (MMR) and other advanced reactor designs.

A pillbox-type radio-frequency window for lower-hybrid current drive power transmission of 3.7 GHz for 200 kW/2 s is designed. The relative permittivity and the loss tangent of several domestic materials—alumina, boron nitride, and sapphire—are exactly compared by the rectangular cavity perturbation method, and finally, the sapphire is chosen as the window medium. The reflection coefficient of the optimized window can reach 55−dB at 3.7 GHz simulated by high-frequency simulation software, and the peak temperature rise can be limited at 20°C with maximum thermal stress of 1.7 MPa by thermal and mechanical analysis. In the high-power test, 221 kW/3 s energy passes the welded window.
