Nature: France and the UK have agreed to build a joint nuclear testing facility in France, using technology developed in the UK.

Although the decision to share the sensitive facility has baffled some, Bruno Tertrais, at the Foundation for Strategic Research in Paris, said that the motivation is “extremely simple: to save money.”
