Neutron diagnostics for fusion power plants

Coordinating university or institute

Uppsala University,



Project description

ITERs main goal is to demonstrate the feasibility of key technologies for the development of future power plants based on fusion energy. ITER is under construction in Cadarache (France) and it is expected to start operation in 2026. In parallel to ITER, the conceptual design of a Demonstration Fusion Power Plant (DEMO) is underway. DEMO is intended to be the single step between ITER and a commercial reactor: it is expected to deliver electricity to the grid in 2050. The measurement of the 2.5 and 14 MeV neutron yield and energy spectrum is required for the determination of the fusion power produced, for the optimal operation of such devices and, ultimately, for the steady state production of electricity.
Design, construction, installation, commissioning and operation of neutron flux monitors and spectrometers in present day fusion devices such as JET and MAST and development of neutron diagnostics for ITER, DEMO and DTT.
