UK contractors' lack of nuclear decommissioning skills is causing delays and contributing to up to ￡lbn of cost overruns at Sellafield, a report by the public spending watchdog has found, writes Vern Pitt. The National Audit Office (NAO) report into the value for money the government has been getting from the decommissioning operation at the Sellafield nuclear site said there had been "underperformance" on major projects at the site. "The portfolio of 14 major projects at Sellafield has so far not provided good value for money, with significant lifetime cost increases and delays of between two and 19 months during 2011-12," the report said. The report estimated cost overruns totalled between ￡652m and ￡1.04bn on the site's major projects.
