A widely heralded view holds that nuclear power is experiencing a dramatic worldwide revival and vibrant growth, because it's competitive, necessary, reliable, secure, and vital for fuel security and climate protection. That's all false. In fact, nuclear power is continuing its decades-long collapse in the global marketplace because it's grossly uncompetitive, unneeded, and obsolete-so hopelessly uneconomic that one needn't debate whether it's clean and safe; it weakens electric reliability and national security; and it worsens climate change compared with devoting the same money and time to more effective options.
