China General Nuclear Power Corp has said it is confident that the Chinese-made Hualong One reactor will pass Britain's strict approval process in five years.

The technology, also known as HPR1000, will be submitted to the UK Office for Nuclear Regulation for its rigorous generic design assessment by the end of this year, the company said.

If it passes, the design will be used at the proposed power station at Bradwell, on the east coast of England, which would be the first nuclear project in a developed market to use a Chinese reactor.
