Dutch research reactor ends use of HEU targets

The Nuclear Research and Consultancy Group has ended its use of high-enriched uranium targets in the production of radioisotopes at the High Flux Reactor in Petten, the Netherlands. The reactor itself was converted from HEU fuel, which can pose a proliferation risk, to low-enriched uranium fuel in 2006.
