Horizon steps closer to Wylfa and Oldbury new build

UK nuclear regulators agree to move to the next stage of assessment of the UK Advanced Boiling Water Reactor (UK ABWR)

Hitachi-GE has also begun a major phase of public and stakeholder engagement, launching a new UK website dedicated to explaining the reactor technology and inviting comments on the design. This process is a central aspect of the Generic Design Assessment (GDA), with all comments responded to, and both questions and answers shared directly with the regulators.

The GDA process is not confined to any specific development, however the UK ABWR is currently proposed for use by Horizon Nuclear Power at two sites: Wylfa Newydd on the Isle of Anglesey, and Oldbury-on-Severn in South Gloucestershire.

Chief Operating Officer of Horizon Nuclear Power, Mr Alan Raymant said: “The GDA is critical to the success of our projects. We’re very pleased to see Hitachi-GE and the regulators moving onto the second stage which marks another important milestone for new nuclear build at Wylfa and Oldbury. This also represents a significant step up in dialogue and information about our reactor design. Later this year we’ll follow this by setting out our plans for our first site Wylfa Newydd, for public consultation”.

Hitachi-GE’s Advanced Boiling Water Reactor (ABWR) has been built at three sites already (four units), and is licensed in three countries around the world. In spring 2013 Hitachi-GE signed assessment agreements with the Office for Nuclear Regulation (ONR) and the Environment Agency, beginning the process of ‘Generic Design Assessment’.

The website – www.hitachi-hgne-uk-abwr.co.uk – has been launched alongside the move to step 2 of the GDA process. The website gives an overview of the reactor design and outlines some of its key features.

The GDA process is led by the Office for Nuclear Regulation (ONR), Environment Agency and Natural Resources Wales (NRW). The regulators’ joint assessment website can be viewed at www.hse.gov.uk/newreactors.
