The current supplementary programme of the High Flux Reactor (HFR), financed by France, Germany and The Netherlands, is managed by the JRC and covers the period 2000-2003. The HFR, located in Petten, The Netherlands, is one of the most powerful multi-purpose research and test reactors in the world and today its operation has been entrusted to the Nuclear Research and consultancy Group (NRG).
In 2002, further to additional indications on weld anomalies discovered in the summer 2001 inspection, serious concerns were voiced about the safety of the plant. Accordingly, on 8 February 2002, in agreement with NRG and the Dutch nuclear safety authority, the �Kernfysische Dienst� (KFD), the European Commission decided to temporarily shut down the reactor. This shut-down period was used for an external safety culture review performed by an expert group of the International Atomic Energy Agency (IAEA), for the definition of an improvement action plan and for an external inspection of the welding anomaly observed during the 2001 inspection.
The IAEA review concluded that the reactor was in good condition and made recommendations and suggestions for further safety improvements.
The shutdown raised major concerns for the continued supply of medical radioisotopes. The issue was raised during an emergency debate in the Dutch Parliament in February 2002 and re-emphasized this crucial aspect of HFR�s role in our society.
The experimental activities were carried out as explained in this annual report.
