France's Revolutionary Nuclear Reactor Is a Leaky, Expensive Mess

France’s new energy minister has called a major French nuclear project “a mess” in public interviews. The European pressurized reactor (EPR) that was commissioned for the Flamanville nuclear power plant, where it joins two existing pressurized water reactors, has been delayed and plagued by problems. The latest extension takes the project timeline from 13 years to 17 at least.

The goal with the EPR design was to continue to kit out the world’s highest-output nuclear plants, with individual reactors that were more powerful and safer. The EPR uses less uranium because its chemical design is more efficient. And it’s not any kind of major technological leap; instead, it’s an iteration on a previous design that’s just a little bit better.
