The Canadian government is investing CAD20 million (USD15 million) of federal funds to accelerate the development of Terrestrial Energy’s Integral Molten Salt Reactor (IMSR) power plant. The IMSR power plant will generate 195 MWe, fueled using standard-assay low-enriched uranium.
The IMSR will produces 40% more electricity than a comparably sized water-cooled SMR. The result is around 40% more revenue from the same reactor size. It will be far safer than current nuclear reactors. They should be walkaway safe. Even if you walkaway it will not overheat because temperature increases will melt a plug and cause the molten material to spread out and cool.
Another walkaway safe reactor design are pebble bed nuclear reactors. China is very close to starting commercial power generation with the HTR-PM 210 MWe reactor.
Cold functional tests have been successfully completed at the first commercial high-temperature gas-cooled pebble bed reactor plant (HTR-PM) in Shandong province. Cold testing of the second unit at the plant has now begun. The twin HTR-PM reactors will drive a single 210 MWe turbine. Helium gas will be used as the primary circuit coolant. The steam generator transfers heat from helium coolant to a water/steam loop. The design temperature of the HTR-PM reaches 750 degrees Celsius.
China has plans for 18 more HTR-PM units at the same site.
China has proposed a larger that is three times bigger. The HTR-PM600 would generate 650 MWe using six HTR-PM reactor units. Feasibility studies on HTR-PM600 deployment have started at five other locations.
