Talk

The ARC fusion power plant will produce 400 MW net electric and is targeting operation in the early 2030s at a site in Chesterfield County, Virginia. ARC will deploy a first-of-a-kind FLiBe salt blanket for the purposes of tritium breeding, converting fusion energy to heat, component cooling and shielding. To enable ARC deployment in the early 2030s, CFS has begun a program of salt R&D work....

Talk

We have undertaken tritium breeding experiments using 14.1 MeV neutron generators for irradiation of capsules filled with molten salts (ClLiF and FLiBe) at temperatures 600C - 700C. Tritium that is bred in the salt is collected by sweep gas into bubblers and then analyzed with Liquid Scintillation Counting. The collected tritium is compared to measured neutron fluences from the neutron...

Presenting on behalf of the TRIBAL consortium
The TRIBAL – Tritium Breeding to Advance LIBRTI project is a collaboration between the University of Edinburgh, Commonwealth Fusion Systems, Eni, the University of California Berkeley, and Xcimer Energy. This project was funded via the LIBRTI feeder stream projects in early 2025 and is unique in developing the FLiBe molten salt breeding blanket....
