Cooperative Agreement
Overview
Grant Description
MCRE – World's First Critical MCFR
To confirm key physics phenomena relevant to MCFR-D, the MCRE Statement of Work (SOW) will include the design, DOE authorization, construction, and operation of a low power, highly enriched uranium (HEU) chloride salt-fueled critical reactor experiment hosted at INL. MCRE will be the first demonstration of a fast spectrum molten salt fuel form in a critical low-power nuclear reactor in the world.
Key Results:
- Design and deliver modules for integration at LOTUS, support INL efforts to obtain DOE authorization, support module installation within LOTUS, and safely operate the critical molten chloride reactor experiment to confirm key, low-knowledge phenomena.
- Support INL efforts to synthesize salt fuel, load salt fuel into the reactor, and operate the liquid salt fueled reactor experiment.
- Summarize key data to support MCFR-D licensing strategy.
