Plutonium Or Greenhouse Gases? Weighing The Energy Options

…In an effort to capture that complete picture, Ewing compared carbon-based fossil fuels with nuclear power, considering not only the technologies involved but also the environmental impacts. Similar comparisons have been made between different energy-producing systems, “but in the case of nuclear power, such an analysis is difficult because there are different types of nuclear reactors and there is not a single nuclear fuel cycle, but rather many variants, with different strategies for reprocessing and disposing of nuclear wastes,” Ewing said.

His presentation, which considers various fuel cycles, shows that nuclear power generation would need to increase by a factor of three to ten over current levels to have a significant impact on greenhouse gas emissions. “We currently have 400-plus nuclear reactors operating worldwide, and we would need something like 3,500 nuclear power plants,” Ewing said.
