Progress in nuclear decommissioning and reprocessing at Sellafield has been poor. Time-scales have slipped, costs have escalated substantially and reprocessing targets have been missed. Costs rise every year and the latest cash estimates for dealing with nuclear waste on the site exceed £70 billion in cash terms. Nuclear Management Partners Limited (NMP) was brought in to improve the performance of Sellafield Limited, the company that manages and operates the site. However, little improvement has been achieved for extra money spent. NMP has not provided the clear leadership, strong management and improved capabilities needed to deliver the performance required at the site. Despite this, the Nuclear Decommissioning Authority (the Authority) extended NMP's contract for a further five year term. The justification for doing this is highly questionable, particularly given a highly critical assessment of NMP's performance by KPMG. The Authority must monitor NMP's activities closely and terminate the contract should performance not improve.
