Three nuclear power plants planned for the UK won't be built, because the foreign companies that were going to build them have decided they were money-losers, even despite the billions in subsidy.

The supposed reason for building them is to have power reliably available even if there is no wind at night. But we already know another way to do that: batteries. Batteries are still somewhat expensive, but are nuclear power plants cheaper? And batteries can't have a massive meltdown that converts a multi-billion-dollar investment into a tens-of-billions cleanup expense.
