In engineering, the simplest design is usually the most elegant, prudent, safest, and cost effective design.
The Light Water reactor design is a Rube Goldberg Machine design which leads to high cost and over complication. *The accident was caused by the destruction of the backup power supplies.* In a reactor design that does not have a need for a power supply then there is no chance for a problem with power supplies. *As far as I know, none of the commercial reactors now sold have passive cooling after shutdown.* China is building a completely passive waste free commercial reactor to be available in 10 years. His will blow the current Light water reactor builders out of the business. . The Chinese are not wedded to the past mistakes of the Americans. *The Three Mile Island accident was caused by a defective reactor design, with a stuck valve and a badly designed instrument panel.* If there is no valve needed in the design then the valve cannot get stuck. If there is no instrument panel needed then this panel cannot be misread.
