This article describes the High Flux Reactor (HFR) belonging to the Institute for Advanced Materials of JRC Petten (NL). It is one of the most powerful multi-purpose research test reactors in the world, supporting research and development in important areas such as: materials and fuel testing for nuclear fission energy; irradiation behaviour of materials for controlled nuclear fusion installations; neutron radiography and neutron activation analysis; research with neutron beams in materials science and medical therapy; production of (radio)isotopes. All types of structural materials: reactor pressure vessel steels, materials for vessel internals, including low-activating alloys and measuring devices, can be tested under current light water reactor (LWR) conditions. More peripheral problems, like radiation degradation of cable insulations of TV cameras, have been addressed within the HFR irradiation programme. The HFR is the largest supplier of radioisotopes for medical applications in Europe. This position will be even stronger with the erection of the molybdenum production unit which enables Petten to offer the complete route from irradiation of targets through to delivery off-site of fission molybdenum.
