Friday marked the point of no return for the permanent shutdown of a major slice of Germany's nuclear energy, leaving a range of unresolved problems caused by the politically-driven reaction to the Fukushima crisis. Berlin is preparing a law change, aiming for July 8, to back the immediate closure of 8,800 MW, or 41 percent of Germany's total nuclear capacity, as of June 17/18, and to shut the remainder by 2022.
