In addition to The Nuclear Decommissioning Authority's costs, British Energy's liabilities in relation to spent nuclear fuels have risen. In February 2006 it was reported that these had increased to £5.3 billion, an increase of almost £1 billion. The costs of handling these is to be met by the Nuclear Liabilities Fund (NLF), the successor to the Nuclear Generation Decommissioning Fund. Although British Energy contributes to the NLF, the fund is underwritten by the Government. The House of Commons Public Accounts Committee noted in 2007 that British Energy may lack an incentive to reduce the eventual liabilities falling to the Nuclear Liabilities Fund.
