Technology Description:

Moltex Energy will develop a multi-physics plant digital twin environment for its Stable Salt Reactor - Wasteburner (SSR-W). SSR‑W is a low overnight-capital plant design, targeting a <$2/kWe build cost. The first-of-a-kind (FOAK) plant uses contemporary approaches to nuclear power plant design and may be encumbered with conventional O&M obligations. The digital twin will be used to evaluate proposed O&M improvements for the SSR-W and empower the FOAK operator to better predict faults and execute remedial actions. A non-nuclear separate effects test loop will support the digital twin development to validate models and address larger uncertainties in flow conditions. By further reducing the SSR-W O&M levelized cost of energy contribution from a current ~$11/MWh to a proposed $1.75/MWh, the potential for transformative energy cost reduction is significant.

Potential Impact:

The program goal is to reduce fixed O&M costs from ~13 $/MWh in the current fleet to ~2 $/MWh in the advanced fleet. Benefits include:

Security:

Establishing U.S. advanced reactor technological leadership and improving U.S. energy security with safe, reliable, dispatchable power for a robust and resilient electric power system;

Environment:

Reducing energy-related emissions with a competitive, carbon-free electricity source; and

Economy:

Increasing productivity and creating a competitive edge for advanced reactors.
