UKAEA, CHIMERA Research Facility Technical Lead
The CHIMERA Fusion Technology Facility
The extreme challenge of realising power production from fusion will require not only fusion reaction demonstrators but also considerable and increasing investment in facilities for testing and developing fusion reactor engineering and technology. Particularly important are the components destined for the harsh reactor core environment. The CHIMERA facility is currently under construction at the UKAEA site in South Yorkshire, and will enable testing of large in-vessel component modules under reactor-like conditions of combined in-vacuo thermal power density and magnetic field. The major challenges addressed include electromagnetic loads, high heat flux, and proving complex and high-risk component manufacturing. The ability to test technology in magnetic fields will be unparalleled and could prove vital for breeding blanket designs featuring a ferromagnetic structural material or a liquid metal breeder. Developments in technologies have been required as part of CHIMERA construction. A bespoke infrared heating system has been developed, capable of applying 0.5 MW/m2 to metre-scale component surfaces. CHIMERA will also feature a range of diagnostics, including load cells to measure static and pulsed magnetic forces, and induced current sensors, all of which have required prior development activities. Testing will be enhanced with simulation ‘digital twin’ capability; the first results are presented which relate to commissioning of the CHIMERA device. The digital twin will combine multi-physics simulations updated with experimental data employing stochastic capabilities. This talk introduces the CHIMERA device, describes the status of construction and development programmes, and gives insight to how ‘virtual testing’ will be used to enhance the development of fusion technology.
