Deals signed by French President Nicolas Sarkozy and British Prime Minister David Cameron on Friday included greater co-operation in developing nuclear energy.
There were agreements between France’s EDF and Aviva and British engineering firm Rolls Royce to build and equip the up to eight nuclear power stations that the UK government is planning.
The initial phase of the project will be worth more than 600 million euros and create 1,500 jobs.
But the British government said that was just the beginning and eventually spending will top 72 billion euros with 30,000 jobs being created.
Plans include setting up training facilities for nuclear industry workers.
Almost one year after the Fukushima nuclear plant disaster in Japan, the UK and France also pledged to work – alongside the International Atomic Energy Agency – on strengthening international capability to react to nuclear emergencies.
