Powering up our world
with cheap, reliable, CO2-free electric power, now.
What is ThorCon? ThorCon is a molten salt fission reactor. Unlike all current nuclear reactors, the fuel is in liquid form. It can be moved around with a pump and passively drained. This 500 MW fission power plant is encapsulated in a hull, built in a shipyard, towed to a shallow water site, ballasted to the seabed. Visit Design.
Ready to Go. ThorCon requires no new technology. ThorCon is a straightforward scale-up of the successful United States Oak Ridge National Laboratory Molten Salt Reactor Experiment (MSRE). A full-scale 500 MW ThorCon prototype can be operating under test within four years. After proving the plant safely handles multiple potential failures and problems, commercial power plant production can begin. Visit MSRE.
Cheaper than Coal. A ThorCon plant requires less of the planet’s resources than a coal plant. Assuming efficient, evidence based regulation, ThorCon can produce clean, reliable, CO2-free electricity at 3 cents per kilowatt-hour — cheaper than coal. Visit Economics.
Rapidly Deployable. The complete ThorCon is manufactured in 150 to 500 ton blocks in a shipyard, assembled, then towed to the site. This produces order of magnitude improvements in productivity, quality control, and build time. A single large reactor yard can turn out twenty gigawatts of ThorCon power plants per year. ThorCon is a system for building power plants. Visit Production.
Fixable. Everything in the fission island except the structure itself is replaceable with little interruption in power output. Every four years the entire primary loop is changed out, returned to a centralized recycling facility, decontaminated, disassembled, inspected, and refurbished. Incipient problems are caught before they can turn into casualties. Upgrades can be introduced without significantly disrupting power generation. Visit Fuel.
Walkaway Safe. ThorCon fuel is in liquid form. If the reactor overheats for whatever reason, ThorCon will shut itself down, and passively handle the decay heat. No power, no machinery, no operator action is required. This is built into the reactor physics. The operators can do nothing to prevent safe shutdown and cooling. ThorCon has at least three gas tight barriers between the fuelsalt and the atmosphere. The reactor operates at garden hose pressure. In the event of a primary loop rupture, there is no dispersal energy and no phase change. The spilled fuel merely flows to a drain tank where it is passively cooled. The most troublesome fission products, including Sr-90 and Cs-137, are chemically bound to the salt. They will end up in the drain tank as well. Visit Safety.
Indonesia project. ThorCon has been working with the Indonesian government to add reliable electric power to the grid. In 2019 the Ministry of Energy successfully completed a study of the safety, economics, and grid impact of the 500 MW prototype ThorConIsle. Phase 1 is to build and test it with step by step commissioning, ending in a type license for future power plants. Phase 2 is shipyard production of ThorCon plants to provide an additional 3 GW of cheap, reliable electric power. Visit Project.
