Current status

ONR granted a Design Acceptance Confirmation (DAC) for the Westinghouse AP1000 design in March 2017 to enable NuGen to construct and operate three AP1000 reactors at Moorside, Cumbria.  In April 2017, Westinghouse filed for Chapter 11 bankruptcy protection in the United States with consequential financial implications for Toshiba, Westinghouse’s parent company.  In June 2017, Toshiba announced its intention to sell Westinghouse and commenced the sale process. When the outcome of this process is known any implications for the Moorside project will need to be fully considered.

Although Toshiba originally appointed KEPCO (South Korea’s largest electric utility company) as the preferred bidder for NuGen, owing to the protracted timescales associated with the sale Toshiba has recently announced that it wished to consider a number of other options for the Moorside site.

As part of the UK government’s consultation on the siting criteria and processes for a new National Policy Statement for nuclear power, BEIS wrote to potential developers, including NuGen, asking them to confirm that they wish the sites to remain listed in a new NPS and to provide information in line with the finalised criteria. NuGen responded to this request in August 2018, submitting the Moorside site for inclusion in the government’s renewed National Policy Statement. 

ONR activity

ONR has continued to engage with NuGen throughout this period to receive updates on its position and to understand the consequential impact on the strategy for the Moorside project.  We will continue to maintain regular dialogue with NuGen until the strategic direction for the Moorside project is confirmed.

Publication of reports

ONR is committed to being an open and transparent body. We have already published ONR's intervention strategy for pre-licence application engagement and will publish on this website the following material:
