Scenario for the development of TTS’s “Molten Salt Furnace”
(1) Development and commercialization of elemental technologies for molten salt furnaces
Molten salt pumps, valves, gaseous fission product removal technology, graphite and Hastelloy N processing and assembly technology, safety analysis technology, power generation system, various measuring devices, decay heat cooling system, and fuel salt composition by 2026 We develop elemental technologies such as analysis systems. These elemental technologies will be commercialized for molten salt furnace ventures around the world.
(2) Development of a 25,000 kW-class ultra-small commercial demonstration reactor
The basic design and implementation design of a 25,000 kW-class ultra-small commercial demonstration reactor will be completed by 2026, and the first unit will be constructed in Japan or overseas by 2028.
(3) Development of 200MW class small main commercial reactor
(3) Development of 200MW class small main commercial reactor
Two years after the construction of the first 250MW-class ultra-small commercial demonstration reactor, construction and operation of the first 200MW-class small main commercial reactor will begin. This flagship commercial reactor, together with the 25,000 kW class commercial reactor, will be the main product for the global expansion of molten salt reactors.
(4) Development of 10,000 kW class micro commercial reactor
Before and after the development of the 200 MW class commercial reactor, we will develop a 10 MW class micro commercial reactor mainly for small-scale power generation on remote islands or for ships.
(5) Development of chemical treatment system for spent fuel salt
Chemical treatment of spent fuel salt is an essential technology for removing fission products and improving efficiency of molten salt reactors. Development will proceed in parallel with development, and a treatment facility will be constructed and put into operation within 10 years after the first 25,000 kW-class commercial demonstration reactor goes into operation.
(6) Development of 1,000,000 kW class main commercial reactor
After the construction and operation of the first 200 MW class commercial reactor, we will develop a 1 000 MW class main commercial reactor as a next-generation flagship commercial reactor with higher economic efficiency. This 1,000MW class molten salt reactor will be the prototype of the breeding salt reactor (different from the breeding reactor in that the spent fuel salt will not undergo continuous chemical treatment), which will be developed later.
(7) Development of molten salt furnace for breeding
Based on the 1,000,000 kW molten salt reactor in ⑥, we will develop a molten salt reactor for breeding uranium fuel (U233).
(8) Chemical processing of spent fuel salt and commercialization of fuel salt supply
Using the technology developed in (5), we will commercialize a business that undertakes chemical processing of spent fuel salt from molten salt furnaces around the world. In addition, we will manufacture fuel salt for molten salt reactors using the breeding uranium produced in the breeding molten salt reactor developed in (7), and develop a business that provides fuel salt to molten salt reactors around the world together with chemical processing.
