Commonwealth Fusion Systems joins UKAEA’s LIBRTI program
Commonwealth Fusion Systems, headquartered in Devens, Mass., has been selected by the U.K. Atomic Energy Authority as the first international partner for the agency’s Lithium Breeding Tritium Innovation (LIBRTI) program. LIBRTI is a U.K. government initiative with the goal of demonstrating the feasibility of fusion power plant–relevant fuel technologies.
The UKAEA is creating a first-of-a-kind technology facility, called the LIBRTI Facility, at its Culham Campus. It will house a test bed made of a 14-MeV neutron source in a shielded blockhouse. This structure will be surrounded by rooms for the assembly and disassembly of multiton breeder blanket prototypes.

Theoretical analysis and interpretation of experimental measurements indicate the need to extend the fluid theory used in the tokamak plasma edge to include ion orbit loss of thermalized ions and to retain (mainly) electromagnetic pinch forces in the momentum balance in order to derive transport equations which conserve particles, energy, and momentum. The features of such an extended steady-state fluid theory have been derived from first principles in several papers and are summarized herein.
