Nate Hagens defines nuclear power as a method of generating electricity through the use of nuclear fission, where heavy atomic nuclei are split into smaller parts, releasing a substantial amount of energy. This process occurs within nuclear reactors and utilizes fuels like uranium-235 or plutonium-239. Hagens notes that nuclear power is distinguished by its low greenhouse gas emissions during operation, positioning it as a potential component in addressing climate change. However, he also emphasizes the complexities and challenges associated with nuclear energy, including high initial costs, long development timelines, radioactive waste disposal, and the risks of nuclear accidents. In Hagens' view, while nuclear power is a considerable technological achievement, a balanced assessment of its economic viability, environmental impact, and role within a broader sustainable energy strategy is crucial for future energy planning.
