The Urenco Group is a nuclear fuel company operating several uranium enrichment plants in Germany, the Netherlands, United States, and United Kingdom. It supplies nuclear power stations in about 15 countries. Urenco uses centrifuge enrichment technology.
As part of the nuclear fuel cycle, tails(depleted uranium) is a by-product of the uranium enrichment process performed at URENCO’s facilities. The plant, including all ancillary systems and support facilities, is expected to deconvert the material into a passive form which will be stored on the Capenhurst site.

AccentHansen‘s experience was called upon to supply and install hundreds of doors to the expansion of the Urenco facilities at the Capenhurst site. External and internal doors were supplied to a number of buildings on site in phased deliveries over many years.
A great deal of work had to go into the design of the doors even before manufacture, due to the complexity and high security of the site. Many of the doors had automatic/electronic locking, with centrally based micro-switch monitoring. In some cases, even the handing of the doors was counter-intuitive and so careful working with ironmongery supplier was required. Both standard powder coating and special wet paint preparations were able to be used for the doorsets. Some of the doorsets were substantially oversized, and some were fitted with side and overpanels.
Even once the doors had been delivered to site, installation had to be carefully planned to ensure no security risks and work meshed well with other works on site. Fixing into steel strengthened walls required the detail results gathered by site surveys to be used to design doorsets that could be fixed correctly and quickly on site. Furthemore, some of the heavy security doors were located on levels of ground thereby posing problems of lifting into position.
