The organisation began to come together in 1996 when a number of separate research and development facilities began to coalesce into a single unit within
British Nuclear Fuels (BNFL). In 2003, this research and technology business was re-launched as Nuclear Sciences and Technology Services (NSTS) to ready the business for transformation into a fully commercial entity. In 2005, following the restructuring of the wider nuclear industry, Nexia Solutions was formed out of NSTS, as a wholly owned subsidiary of BNFL. In July 2006, the
UK Government stated its intention to preserve and develop key research and development capabilities potentially as part of a National Nuclear Laboratory (NNL). In October 2006,
Secretary of State for Trade and Industry,
Alistair Darling, announced the establishment of the NNL, to be based on Nexia Solutions and the British Technology Centre at the
Sellafield facility. NNL was formally announced by
John Hutton,
Secretary of State for Business, Enterprise and Regulatory Reform in an announcement at the Sellafield Visitors Centre on 23 July 2008. On 23 March 2009 it was announced by the
Department of Energy and Climate Change (DECC) that a consortium made up of
Serco,
Battelle and the
University of Manchester had been selected as the new management contractors for the NNL. The contract was for an initial three-year period with options to be extended by up to two years. DECC had been engaged in competitive dialogue with the winning consortium as well as QQEST, a joint venture between
QinetiQ and
EnergySolutions, since October 2008. The management contract commenced on 1 April 2009, when ownership of the NNL transferred from BNFL directly to DECC with shareholder responsibilities delegated to the
Shareholder Executive. Mike Lawrence of Battelle was appointed to lead the new NNL management team as managing director. He had more than 40 years of experience in the nuclear profession, including management of the United States Hanford Reservation and its massive site clean-up program, and his former role as the U.S. representative on nuclear matters to the
International Atomic Energy Agency. Mike Lawrence retired in December 2010 and was replaced by Professor Paul Howarth, formerly NNL's Director of Science, Technology and Project Delivery. On 1 October 2013, the management contract expired, and the NNL became operated directly by the
UK Government. In December 2024 the organisation was renamed United Kingdom National Nuclear Laboratory, and began using the royal coat of arms. ==Other information==
