The view is based on some false assumptions. Nuclear reactor fuel can be efficiently recycled. Besides, the reason why storage of nuclear fuel is expencive is because nuclear industry actualy takes care of biproducts of operation, unlike other industries that produce equally or more dangerous chemical waste. It is also not true that a system failure would "devastate huge territores". No PWR accident had major consequences on human health, even in Fukushima there were no fatalities from radiation. Statistically nuclear power is the safest form of electricity. The largest storage battery (Australia) can replace a NPP for about 10 seconds. In winter you might have no sun and wind for weeks. This is why you are, and will continue burning fossil fuels in Germany.
