British Nuclear Fuels is planning to sell nuclear clean-up business British Nuclear Group in several parts following a dispute with the Nuclear Decommissioning Authority.

As part of the government's gradual sale of its nuclear assets the state-owned BNFL wanted to sell BNG along with a potentially lucrative five-year contract to manage the Sellafield complex in Cumbria, the biggest and most contaminated nuclear site. The contract could be worth about £1bn a year and would have been important in determining the value of BNG.
