The Memorandum of Understanding between Nuclear South West and Nucleopolis will see the two economic development organisations work together to connect companies with £50 billion worth of nuclear investments in South West England and an annual market in Normandy worth more than £1 billion a year.
The nuclear industry in Normandy employs around 28,000 people.
Nucleopolis, the nuclear unit of Normandie Energies, brings together expertise of nearly 100 French organisations, covering research and training in the fields of energy, health and risk management.
Matt Burley, Nuclear South West Chairman said: “This agreement is hugely important to us as it helps build awareness of the South West as a destination for companies to invest in and do business with the nuclear supply chain.
“France is recognised as being one of the most advanced nuclear nations and Nucleopolis has a significant role to play in helping the industry to grow. We look forward to developing our relationship with Nucleopolis and working closely to being opportunities to the South West and France.”
