Lessons learned from nuclear accident can improve creches
The Three Mile Island nuclear power plant accident in 1979 had the greatest impact on nuclear regulation of any single event in history. The main pumps feeding cooling water into the reactor stopped running, preventing the steam generators from removing heat. This led to half the reactor core melting down. Three Mile Island could have been a Chernobyl-level nuclear disaster. It led to huge changes in how nuclear plants are regulated internationally.
