Description
The High Flux Test Module (HFTM) of the International Fusion Materials Irradiation Facility (IFMIF) is a device to enable irradiation of Small Scale Testing Technique (SSTT) specimens by neutrons up to a structural damage of 50 displacements per atom (dpa) in an irradiation campaign of one year. The IFMIF source generates neutrons with a D-T-fusion-relevant energy spectrum and a flux to achieve a damage rate over 20 dpa per full power year in a theoretical volume of 0.5 l. Irradiation temperatures are required in the range of 250 - 550°C.
According to the IFMIF conditions and requirements, the IFMIF HFTM has been developed in the IFMIF/EVEDA phase and a prototype was constructed and tested.
The manufacturing process of relevant parts, like attachment adapter and container, is presented – especially in regard of problems in manufacturing accuracy. The capsule manufacturing process in regard of brazing process and finishing of the capsule shape is explained in detail. Further the instrumentation of the prototype for experimental data generation is presented. Optimization potentials derived from the manufacturing process and the experimental experiences are highlighted.
