Lesson: A damaged nuclear reactor is a danger forever. Is there any such thing as a nuclear reactor that’s NOT damages?
TOKYO — The operator of the Fukushima Daiichi nuclear power plant stood ready Thursday to inject boric acid into one of its most heavily damaged reactors after it found steam emanating from the reactor building. The preventive measure would stave off criticality, or an uncontrolled nuclear chain reaction, in the reactor’s damaged core.
The incident has brought the Fukushima plant’s vulnerable state into sharp relief, more than two years after its reactors suffered multiple meltdowns when its cooling systems were overwhelmed by a powerful earthquake and tsunami.
