Abstract: This White Paper proposes the Fission-Fusion Hybrid Molten Salt Reactor (FFHMSR) as the solution to the world's growing need for abundant, carbon-free, safe electricity. The FFHMSR combines a critical molten salt fission reactor with a fusion source of energetic neutrons in a single connected system, offering advantages that neither has independently. The molten salt reactor provides improved safety and greater efficiency, while the neutron source's high energy neutrons eliminate the need for fuel enrichment and reprocessing and can remove all actinides from the waste stream. The dynamic balance between the dual processes capitalizes on their strengths and synergies.
 
The FFHMSR enables a closed fuel cycle and a 100-fold increase in fuel utilization. The FFHMSR provides greatly increased proliferation resistance and a greatly reduced volume of waste. It can be fueled with spent nuclear fuel, mined uranium, depleted uranium and abundant thorium. This novel concept, an implementation of an idea patented in 20166, relies on technology available today. The FFHMSR combines nuclear fission and nuclear fusion in an integrated system with each doing what it does best.
