Since 1 April 2005, the shares of United Kingdom Nirex Limited (Nirex) have been held by a new company limited by guarantee (CLG), jointly owned by the Department for Environment, Food and Rural Affairs and the Department of Trade and Industry. The CLG board will oversee the operations of Nirex in accordance with a business plan agreed with the company each year. Day-to-day management of Nirex, in accordance with the business plan, will be the responsibility of the Nirex board. Under the new arrangements over 90 per cent. of the funding for Nirex work will be provided under a contract with the Nuclear Decommissioning Authority (NDA), with the remainder coming from the continuing memorandum of understanding with the Ministry of Defence, and individual contracts with waste producers for advice on its conditioning and packaging.
