Nirex was latterly a
United Kingdom government body that had originally been set up in
1982 by the UK nuclear industry to examine safe,
environmental and
economic aspects of deep
geological disposal of intermediate-level and low-level
radioactive waste. Originally known as the Nuclear Industry Radioactive Waste Executive, it became the
limited company United Kingdom Nirex Limited in 1985. The ownership of Nirex was transferred from the nuclear industry to the UK Government departments Defra and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006. Nirex's staff and functions were integrated into the NDA in April 2007, at which point Nirex ceased trading as a separate entity. Nirex's role continues through the activities of the Radioactive Waste Management Directorate of the NDA.
