1. Legal hurdles. "The previous law was changed to close the nuclear power plants after Fukushima."
2. Safety. "To keep the reactors open in 2023, Germany would need to accept accelerating the risk assessment and maybe living without some retrofittings."
3. Fuel. "The reactors would then need new fuel, which would take 12-15 months to arrive, and would require a doubling of manufacturing capacity."
4. Spare parts. "They also fear that some spare parts would be lacking because there is no further market in Germany for them."
5. Personnel. "People have been retiring and no new ones have been trained, so it would be hard to get the people."
6. Economics. "With lack of clarity on spare parts and personnel, how can we commit to a reliable delivery or energy? We can’t be 100% confident."
7. Energy replacement. "Until the new nuclear fuel is in place, we would make up for the shortage with more electricity coming from coal and gas."
