Fears have been raised over jobs and safety if a nuclear site is given “lock, stock and barrel” to a Chinese corporation.

In 2011, the Government earmarked Bradwell as one of eight sites for a new nuclear power station to be built in the UK by 2025.

China is already funding a new power station in Hinkley Point, Somerset, and a leading union - the GMB- is concerned this deal has been done on the basis that a Bradwell site will be handed over to the Chinese and they will be allowed to use their own technology there.

An EDF spokesman said: “The UK’s nuclear regulation ensures that all builders and operators must demonstrate that they operate in the interests of the UK and meet strict compliance requirements for safety and security.

“EDF Energy has many years of experience working within this robust regulatory regime.

“EDF Energy has worked with its Chinese partners for more than 30 years.

“A partnership in the UK, starting at Hinkley Point C, will give CGN and CNNC the opportunity to gain experience and will support their long term objective of becoming nuclear developers in full compliance with UK regulatory requirements.”
