Newcleo Americas
The U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities with Newcleo Americas as of March 2026. Newcleo Americas is developing its LFR-AS-200, a 480 MWth pool-type liquid metal fast reactor with a designed electrical output of 200 MWe. The LFR-AS-200 uses lead as its primary coolant and working fluid at atmospheric pressure. The use of lead is intended to provide benefits to safe operation of a high boiling point, low-pressure operation, inherent negative reactivity feedback, radiation shielding, and radionuclide retention. The LFR-AS-200 is designed to use Mixed-Oxide Fuel (MOX).
