Another WSJ article today describes small nuclear reactors as an unproven way to deliver electricity. "Unproven?" So the Journal never heard of nuclear submarines or aircraft carriers---which have had no injury accidents in over 60 years?
Opposition to small modular reactors is know-nothingism per se. They do not explode. They do not melt down and burn a hole to China. There is no ionizing radiation escaping. We now have nuclear medicine in dentists offices and hospitals all over America. Those who oppose it now stopped having an open mind after nutty 1950s movies about giant crabs, Homer Simpson's employer, and absurd anti-nuclear war propaganda from the Reefer Madness era.
