For people new to the nuclear-power-as-possible-fraud issue, here are a few notes:--
 The 'father of nuke revisionism', 'cactusneedles' or 'alexis1111', considered that post-1945 estimates of electricity demand were far too high, so that in his view coal-fired power stations (and hydro-electric power - he lives in Canada) had surplus production. He attributed the surplus to the introduction of transistors - which meant 'tubes' or 'valves' became obsolete so that radio sets, TV, and music amplifiers all needed far less power. There was of course also a move to improved insulation, mainly through trapping air more efficiently, by glass (in double and triple glazing) and in plastic and rubber foams. On the other hand there was a vast increase in such appliances as washing machines, dishwashers, fridges - but of course clothes and plates were washed and food preserved before these gadgets were invented, so the net change isn't easy to assess without empirical evidence. Vacuum cleaners must have increased demand. But showers, I take it made easier by improved pumps, are generally believed to use less heat than baths.
Looking at the situation now, factory consumption of electricity must have been influenced by the shift to China (which has large numbers of coal-fired power stations). There have been technical improvements in cooking - microwaves and induction hobs and kettles with a flat heating element at the bottom transfer energy more or less without waste to food and water; and combi ovens cook in much smaller volumes than traditional ovens. If LED lighting continues to be improved, the whole appearance of homes will change, and lights will need only a small power supply. Computers are more efficient. I would guess air conditioning is more efficient. And of course there are other supplies - solar power contributes significant distributed amounts of electricity.
Bear all this in mind when trying to assess the situation in France.
 Our working hypothesis is that nuclear power stations are, in part or wholly, a fraud - simply dumploads to even out changes in electricity demand. (See my piece on DUMPLOADs). This would help explain the complaint about heating of river water, although it does not explain the timing - very possibly the fraud controllers are nervous and starting to phase the things out, with, of course, huge payments - see my piece on Sellafield on the way claims of radiation danger permit 'experts' to cream off money for decades.
 Note that the European Union is an undemocratic structure, foisted on Europe in a peacetime analogue of the way the 'Soviet Union' was foisted on Russians and east Europeans. It has a remarkably similar structure, with undemocratic 'leaders' and voters who, although returning MEPs, have no effects on policy, an amazing example of a hoax. Anyway, it was preceded by the ECSC, the 'European Coal and Steel Community'. Much European coal happens to be in Germany and its border with France, so probably the nuclear power fraud, if it was a fraud, was introduced right at the start, with France taking the credit for the supposedly advanced technology, in rather the way the USA took the credit for NASA's frauds.
Anyway - watch for these things. In brief, France taking electricity from Germany and ditching its 'nuclear power plants', under conditions of secrecy and finance to try to ensure the truth doesn't get out. And watch for problems over the continuing demands for money for 'decommissioning', possibly a few mysterious deaths, and more EU lies around 'climate change' - they will have to modify their lies if power is mostly coal-based.
