Technology Description:

The Massachusetts Institute of Technology’s Plasma Science and Fusion Center and Idaho National Laboratory, with its Safety and Tritium Applied Research Facility, propose a critical-path tritium-breeding experiment for LIB technology. The technological development for LIBs requires high temperatures, hazardous material handling and access to D-T fusion neutron sources. The Liquid Immersion Blanket: Robust Accountancy (LIBRA) experiment will investigate tritium-breeding capabilities under these extreme conditions. It will examine a simple molten-FLiBe-salt approach to tritium-breeding for fusion power plants and show this is possible with 70% lower-cost LIB technology than state-of-the-art breeding blankets.

Potential Impact:

The LIBRA team will demonstrate unprecedented tritium-breeding ratios possible with 70% lower cost LIB technology.

Security:

LIBRA offers the energy market a representative T-breeding test stand that provides T containment and real-time accountancy.

Environment:

Successful LIBRA development would dramatically accelerate tritium-breeding and the deployment rate of fusion power.

Economy:

LIBRA's success would enable a LIB prototype demonstration and create a new technology-to-market pathway to tritium-breeding for fusion power plants at substantially lower cost than conventional blankets.
