Some of our finest Citable Articles (145) Developed Articles (1,128) (16,526 total articles) Good prose is like a windowpane. — George Orwell (1903–1950) Why I Write        —add a quotation about knowledge or writing Featured Article: Nuclear power reconsidered After decades of failure to slow the rising global consumption of coal, oil and gas, many countries have proceeded as of 2024 to reconsider nuclear power in order to lower the demand for fossil fuels. Wind and solar power alone, without large-scale storage for these intermittent sources, are unlikely to meet the world's needs for reliable energy. See Figures 1 and 2 on the magnitude of the world energy challenge. Nuclear power plants that use nuclear reactors to create electricity could provide the abundant, zero-carbon, dispatchable energy needed for a low-carbon future, but not by simply building more of what we already have. New innovative designs for nuclear reactors are needed to avoid the problems of the past. (CC) Image: Geoff Russell Fig.1 Electricity consumption may soon double, mostly from coal-fired power plants in the developing world. Issues Confronting the Nuclear Industry New reactor designers have sought to address issues that have prevented the acceptance of nuclear power, including safety, waste management, weapons proliferation, and cost. This article will summarize the questions that have been raised and the criteria that have been established for evaluating these designs. Answers to these questions will be provided by the designers of these reactors in the articles on their designs. Further debate will be provided in the Discussion and the Debate Guide pages of those articles. Footnotes Continued...
