French PWRs routinely load-follow, ramping 1-5% of rated power per minute. With ~70% nuclear generation, they had no choice but to design for flexibility. Their N4 and newer reactors can operate between 20-100% power on demand.

This is not about technical possibility, but about economics. The cost of nuclear is capital cost while operating costs are small, you want to run your plant at maximum capacity.

France has cheaper electricity that Germany.

You are repeating talking points without understanding. First, there are different prices which also change in time. Also, the price households pay does not relate to generation cost. But even the wholesale price is does not necessarily do this. In France, the problem is that EDF is required to sell electricity from old nuclear plants very cheaply, but this is not even good for the nuclear industry, in fact, it one reason (the other are why it now has a lot debts and is not able to do the necessary investments. But even without these historical rules, it is difficult to fund new nuclear power plants using the expected price levels for electricity in Europe.
