Sleepy,
it´s all in german, send me a pm if i shall translate something.
if you search google with "kohlesubventionen deutschland" you will get much information. This study
https://www.greenpeace.de/sites/www.greenpeace.de/files/Kohlesubventionen_1950-2008_0.pdfwill povide you with many sources and information about subsidies of german coal plants and mining. It is a very traditional business in Germany and has very active lobbyism in the gouvernment. Yhere are not only direct subsidies, but also indirect subsidies like tax reductions, cost partitioning for restoring of environment etc etc, it is a long list. You can be sure that without subsidies there would not be one german coal plant left, not to talk about nuclear.
According to the nuclear plants there is not much available if you do not have insight in construction and maintainace problems of these plants. The main problem is that all pants are constructed under presupposition of a limited number of starts and shutdowns. These presumptive conditions of drift has never been met for any of the german plants. Numbers of starts and shutdowns exceed by far the constructive limits.
Vital components in nuclear power plants are not replaceable, and when you understand, that every mechanical part will fail some day, and that part failure of a series of similar parts follows a gaussian normal curve. This curve has to be very steep in the case ov nuclear plants due to the fact that you can not afford any premature part failure.
Bt this means too, that you must avoid drift longer than the constructive limits allow or drift under unusual circumstances outside the constructive limits (meaning numbers of shutdowns and start ups) because you leave the safe side of the normal curve very fast.
This is in fact a problem most mechanical engineers know about (or should know about).
Before Fukushima the german government decided that german nuclear plants should get a prolonged drift WITHOUT further maintainance or upgrading, this under heavy press from E.ON, RWE and Vattenfall. In my opinin this was a safe recipe for desaster. I my private opinion i am rather sure that Angela Merkel was very pleased about the Fukushima desaster, because it gave her the opportunity to overrule the big companies and force a shutdown of the plants.
