nuclear fission power plantPopular Mechanics

Scientists in China have designed and tested a nuclear fission power plant that can keep itself cool even during a power outage.
The design involves a new paradigm called a pebble bed reactor.
The reactor reached a maximum temperature of just 870C after 3.5 hours without power.
This avoids the runaway heating and disaster known as nuclear meltdown.
Indeed, careful and rigorous design can turn a brittle, meltdown-vulnerable traditional fission reactor into something more flexible and safe. And all it takes is a step down in power density and a smarter approach to materials. These scientists believe our future is worth the tradeoff..
