URENCO Deutschland (UD), lcoated in Gronau, is the site of URENCO’s uranium enrichment plant in Germany. It is located close to the Dutch/German border in North-Rhine-Westphalia, some 40 km from URENCO's Dutch enrichment plant. Here uranium is enriched in centrifuge cascades to the U235 assays required by nuclear power plants.
As with all URENCO sites, Gronau aims to be at the forefront of environmental performance and through continual improvement endeavours to reduce the impact of its activities on the environment.
The Gronau plant began operation in August 1985. By the beginning of 1998 the plant reached its original design capacity of 1,000 tonnes separative work per annum (tSW p.a.). Since then the plant has expanded continuously, on the strength of several additional nuclear licences, with capacity of 4,200 tSW/a at 31 December 2011.
