Die Gewaltttigkeiten fhrten zu kontroversen Diskussionen ber die Legitimitt verschiedener Methoden des Protests. At the end of a 12-year operating cycle the whole plant is taken to a central facility for two-year overhaul and removal of used fuel, before being returned to service. Each operated intermittently at about 20 kW thermal, the reaction ceasing whenever the water turned to steam so that it ceased to function as moderator. Several generations of reactors are commonly distinguished. After a day, the decay heat falls to 0.4%, and after a week it will be only 0.2%. A similar statement was voiced by SPD MP Udo Bullmann who explained that Germany has to stick with fossil fuels as it's trying to replace both coal and nuclear "at the same time", while countries that rely on nuclear power have "easier task replacing fossil fuels". Ambassador to Israel Tom Nides congratulated Benjamin Netanyahu for his election win and return to power as Israel's Prime Minister Thursday.
