Engineering giant Toshiba, which owns Westinghouse, intended to build three of its AP1000 reactors at the proposed power station complex, near to Sellafield.
The site was to generate 3.8GW, making it the engine for the Northern Powerhouse.
Toshiba, which owns a controlling stake in the Moorside nuclear station developer NuGen, is considering axing projects outside of Japan after running up vast losses estimated to run to billions of dollars.
These stem from losses on existing nuclear construction projects and write downs from Westinghouse’s purchase of CB&I Stone & Webster – a US construction firm that specialises in nuclear power projects.
Over the last year extensive site investigation has been undertaken alongside a massive public consultation exercise over Moorside.
