La Hague dumps radioactive waste liquids into the North Sea. Reactors currently cannot run 100% on MOX. Separation of Plutonium in the recycling process has proliferation concerns. Other countries have found building similar recycling plants challenging due to cost, with DoE estimating $50+ billion. La Hague was initially designed to extract Plutonium for weapons use, which likely justified its costs at the time.
The Marcoule site where MOX fuel is manufactured had an explosion in 2011, which did result in a fatality.
