The High Flux Reactor (HFR) Petten, managed by the Institute of Advanced Materials (IAM) of the JRC of the European Commission, is one of the most powerful multi-purpose materials testing reactors in the world.

The HFR is of the tank-in-pool type, light water cooled and moderated and operated at 45 MW. In operation since 1962, and following complete refurbishment in recent years, the HFR has a technical life beyond the year 2015.

The reactor provides a variety of irradiation facilities and possibilities: in the reactor core, in the reflector region, in the poolside. Horizontal beam tubes are available for research with neutrons. Gamma irradiation facilities are also available. Excellently equipped hot cell laboratories, on the Petten side, can provide virtually all envisaged post-irradiation examinations.

The close co-operation between the JRC and the NRG1 on all aspects of nuclear research and technology Is essential to maintain the key position of the HFR amongst research reactors worldwide. This co-operation has led to a unique HFR structure, in which both organizations are involved with the aim to adopt a more market orientated approach and offer their long-standing and recognized competence in exploiting a powerful, reliable set of nuclear facilities to world-wide interested parties.

HRF is also in the core of the Medical Valley association. This association between IAM, NRG, Mallinckrodt Medical, Urenco and hospitals leads to a medical structure unique in the world.
