Last year, Japan's Hitachi bought a new nuclear joint venture company from Germany's RWE and E.ON , underlining interest from Asian firms in entering Britain's nuclear industry.
Last month, Britain also signed a cooperation agreement with Russian nuclear conglomerate Rosatom.
Britain has shortlisted eight sites that can house new nuclear plants, two of which are owned by Hitachi, one by a joint venture between GDF Suez and Iberdrola and the remainder by EDF.
