During the 1960s when the American Advisory Committee on Reactor Safeguards debated containment structures, some members argued for the need to make stronger containments. Regrettably, a majority of the members believed that the emergency core cooling systems were adequate, so more than 50 years ago the Advisory Committee ignored its minority members and pushed ahead without rigorous failure-proof containment structures and systems. The Nuclear Regulatory Committee made the decision not to require stronger containments. Japan followed the American lead.
