  1. Continuing concerns: safety sustainability and waste Westminster Energy Environment & Transport Forum  Nuclear Energy 27 Oct 2010, Princess Alexandra Hall London Dr Paul Dorfman

  2. Epistemological chicken • ‘Justification’ is going ahead before EPR, AP 1000 reactors have been approved by UK regulators.

  3. Despite • A failure to account for the Generation III nuclear fuel performance and characteristics. • Rather heroic expectations for the surety of the nuclear island containment.

  4. Regulators in Finland, France and the UK, operating in concert, have expressed serious reservations about the EPR design - particularly whether there is sufficient independence in the control systems.

  5. High burn-up fuel • Performs very poorly when subject to abnormal conditions. • Liable to release a much higher content of its fission product inventory than its Generation II counterpart.

  6. Immediate release fraction • Over the six days of open containment 30-60% of the Chernobyl reactor core fission products were released to the atmosphere. • AREVA EdF EPR ‘worst case’ estimates - including terrorist attack – insist that no more than 0.2% of the core content would be released over six days.

  7. Geological ‘disposal’ • Nowhere in the world has intermediate or high-level radioactive waste been safely disposed. • GDF R&D required by CoWRM have not been undertaken. • OND Decc are said to be ‘sitting on’ CoRWMs recent report.

  8. Over-runs

  9. Over-runs • July 2010, Areva announced further losses of €367m on the Olkiluoto contract, originally priced at €3bn, but now estimated at €5.7bn. • EPR Flamanville: EDF confirmed the project was running two years late and increased its estimate of the cost overrun from 20% to more than 50%.

  10. US pull-out • Withdrawal by US EdF partner Constellation Energy from their project to build a French-designed EPR reactor at Calvert Cliffs, Maryland. • Constellation forced to withdraw because of ‘high cost of financial support from the US government’.
