Question

To ask the Secretary of State for Energy and Climate Change, pursuant to the Answer of 2 November 2015 to Question 13044, what the (a) technical, (b) regulatory and (c) contractual reasons were for delays at (i) Olkiluoto 3 and (ii) Flamanville 3 reactors.

The causes of the delays at Olkiluoto 3 include complex contractual structures and a series of design changes suggested by the local regulator after the start of construction. Hinkley Point C will commence construction with a more mature design. Our different regulatory regime and improved contracting arrangements will ensure that issues will not arise in the UK.

Flamanville 3 has experienced delays as a result of changes to the design after the start of construction, changes to regulatory requirements, including modifications to take account of lessons learned from the accident at Fukushima in 2011, and quality problems with key components. In the UK, responsibility for delivery and compliance with regulatory requirements lies with EDF and its co-investors. The shareholders in the project carry the full construction risk.

EDF Energy, overseen by the UK’s Office for Nuclear Regulation, will apply any relevant lessons learned and ensure the delivery of high standards of nuclear safety for its new nuclear power plants in the UK.
