我々の技術力

For commercial fusion to be a reality, key technologies for the fuel cycle and for power generation – most importantly, fusion reactor exhaust systems and tritium breeding blankets – must be developed.
These components are exposed to extreme conditions – high thermal, neutron, and particle loading – meaning they must be designed to achieve high performance.
In addition to demonstrating high-performance, for a commercially viable fusion reactor they must also be cost-effective and easy to build, as they are consumable and must be replaced.
Kyoto Fusioneering will design, build, and test technologies for the fusion industry, working with companies to customize components to address the challenges faced in specific reactor designs.

Blankets
(tritium breeding & power generation)

Kyoto Fusioneering is exploring two flowing liquid blanket concepts:

  1. 1.Liquid metal(lead-lithium)
  2. 2.Molten salt(including FLiBe salt)

The blanket will be dual cooled. Heat will be extracted via circulation of liquid metal or salt through a heat exchanger and via additional helium coolant channels. The heat transferred from the liquid breeder will be used for highly efficient power generation. This is possible through use of advanced metals and ceramics – Japanese fusion-grade steel and novel silicon carbide (SiC) materials – which will eventually allow for very high temperature operation (~1000oC).

The lithium in the blanket will interact with the fusion neutrons to breed tritium, which will be extracted to allow the fusion reactor to be self- sufficient on fuel. Novel technology for the efficient extraction of tritium from the breeding liquid in the blanket will be further developed for commercial application.
The technology will build on existing designs, R&D, and testing facilities at Kyoto University fusion laboratories. The technology will be developed via simulation and experimentation, following an agile innovation cycle of “build- test-learn” iteratively towards deployment in a relevant in a fusion reactor demonstrator.

Exhaust
systems

排気系

An exhaust system is required to remove and separate unburnt fuel, helium ash from the fusion reaction, and impurities from the reactor. The deuterium and tritium fuel must then be recovered and recycled to refuel the reactor.

Exhaust systems on magnetic confinement reactors are in physical contact the plasma. These exhausts – called divertors – are subject to the most extreme conditions of heat, radiation and energetic particle loading. Divertors must use advanced materials and designs that enable operation at high performance and for long periods of time before they are replaced.

Kyoto Fusioneering is developing divertors capable of handling the heat from the exhaust region to contribute to power generation, and to separate, recover and recycle unburnt fuel, fusion products and impurities.

For target-based reactors, including laser- driven and magnetized-target fusion reactor concepts, Kyoto Fusioneering is developing technology to extract, recover and recycle unburnt fuel, fusion products, and impurities from the reactor chamber.

Kyoto Fusioneering is developing its capabilities to address other key challenges in fusion commercialisation. Other key activities also under development include:

  1. 1 –Designing tritium handling systems and manufacture of tritium system components to integrate with advanced breeding blanket systems.
  2. 2 –Engineering high-power, high-frequency microwave gyrotrons for tokamak plasma heating.
  3. 3 –Conceptual modelling for commercial fusion applications to understand how fusion can solve global environmental problems and decarbonize the world economy. Advanced energy applications such as desalination, hydrogen production and fusion-carbon capture systems are being explored.
