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. Six fission chambers will be supplied under the contract baseline, with the possibility of two spares that would be supplied under an option. Please refer to Technical Specifications (Annex B) for additional information/details.
