 In December 2013, Toshiba, through its Westinghouse subsidiary, purchased a 60% share of NuGeneration, with the intention of building three AP1000s at Moorside near the Sellafield nuclear reprocessing site in Cumbria, England, with a target first operation date of 2024.On 28 March 2017, the Office for Nuclear Regulation (ONR, UK) issued a Design Acceptance Confirmation for the AP1000 design, stating that 51 issues identified in 2011 had received an adequate response.However, the following day the designer, Westinghouse, filed for Chapter 11 bankruptcy in the U.S. because of $9 billion of losses from its nuclear reactor construction projects, mostly the construction of four AP1000 reactors in the U.S.
