Nuclear Power Is the Best Climate-Change Solution by Far

Its total greenhouse-gas emissions are 1/700th those of coal—and one-fourth those of solar

By Andrew I. Fillat and Henry I. Miller. Mr. Fillat, an electrical engineer, has worked for technology venture-capital and information-technology companies. Dr. Miller is a physician and molecular biologist, and a senior fellow at the Pacific Research Institute. Excerpts:

"the single greatest sin is the demonization of nuclear power, including the shutdown of existing nuclear plants that remain serviceable. Moreover, significant advances in nuclear power plant design that have improved efficiency and safety have been ignored."

"Jacopo Buongiorno, a nuclear-engineering professor at the Massachusetts Institute of Technology, has calculated that over the life cycle of power plants, which includes construction, mining, transport, operation, decommissioning and disposal of waste, the greenhouse-gas emissions for nuclear power are 1/700th those of coal, 1/400th of gas, and one-fourth of solar. Nuclear also requires 1/2,000th as much land as wind and around 1/400th as much as solar. For any given power output, the amount of raw material used to build a nuclear plant is a small fraction of an equivalent solar or wind farm. Although nuclear waste is obviously more difficult to dispose of, its volume is 1/10,000th that of solar and 1/500th of wind. This includes abandoned infrastructure and all the toxic substances that end up in landfills. One person’s lifetime use of nuclear power would produce about a half-ounce of waste. Even including the Chernobyl disaster, human mortality from coal is 2,000 to 3,000 times that of nuclear, while oil claims 400 times as many lives."

"One appealing approach is to replace large-scale facilities with many smaller but safer, cheaper and more-manageable ones. The $10 billion 10-year planning and implementation cycle for a large nuclear plant can be cut in half with a small modular reactor and another half with a microreactor."

"We could deploy SMRs today if we could surmount the negative propaganda about the nuclear industry. Microreactors could generate between 1 and 20 megawatts of power (enough to provide electricity to 500 to 20,000 homes) while needing to refuel only once every five to 10 years. They are air-cooled, capable of being shut down rapidly with no risk of radioactive release and occupy small spaces."
