The UK and China signed two agreements 17 June enabling Chinese companies not only to invest in nuclear power plant projects but also to build Chinese design nuclear reactors in the UK, the Department of Energy and Climate Change - DECC - said. The agreements were signed during the China Premier Li Keqiang official visit to the UK between 16 and 19 June, 2014. The joint civil nuclear agreement signed yesterday also aims at better cooperation in the wider nuclear fuel supply chain cycle by working together to develop and export innovative solutions in areas such as waste treatment and decommissioning which could be worth hundreds of millions of pounds to British companies over several years. The agreement builds on a memorandum of understanding the UK signed with China last October, 2013, which set out a framework of cooperation in civil nuclear energy, DECC said. The second and separate agreement is a four-way memorandum of understanding between DECC, CNNC, China Atomic Energy Authority, and International Nuclear Services - the commercial arm of the UK Nuclear Decommissioning Authority. DECC said this landmark agreement would enable Chinese companies to own and operate a Chinese-designed nuclear power plant in the UK, provided they meet UK regulatory requirements.
