Final design (based on provided functional specifications), manufacture and delivery of Fission Chambers for the ITER Radial Neutron Camera (RNC) Diagnostic System. The RNC is a neutron diagnostic aiming to provide the spatial profile of the neutron emissivity during the burning of thermonuclear deuterium and tritium plasma. 6 fission chambers will be supplied under the contract baseline, with the possibility of 2 spares that would be supplied under an option. Please refer to Technical Specifications (Annex B) for additional information/details.
