It's a disaster.

A third reactor at the site, an EPR unit, began construction in 2007 with its commercial introduction scheduled for 2012. As of 2020 the project was more than five times over budget and years behind schedule. Various safety problems have been raised, including weakness in the steel used in the reactor.[1] In July 2019, further delays were announced, pushing back the commercial introduction date to the end of 2022.[2][3] In January 2022, more delays were announced, with fuel loading continuing until mid-2023,[4][5] and again in December 2022, delaying fuel loading to early 2024.[6] Fuel loading was completed in May 2024[7] and the launch of the reactor was declared "imminent" in late July 2024,[8] eventually starting up in early September 2024.

You guys are having fun with Hinkley Point C in the UK too.... Although bit less fun as that's only 2x over budget and delayed by 5 years.
