The cooling mechanism of the reactor works without drawing external energy and can bring reactor to stable temperatures within few hours.

In a global first, researchers at Tsinghua University in China have successfully demonstrated a meltdown-proof nuclear fission reactor. The twin reactor design can generate 105 MW of power each and has been in the works since 2016. The technology is a welcome step for the nuclear energy industry after the meltdown at Fukushima in Japan more than a decade ago.

Typically, the cooling mechanisms use water or carbon as cooling agents and are backed by external power supplies to ensure that the reactor temperature stays within control. In 2011, the Fukushima nuclear reactor experienced a rare event in which the standard and emergency power supply to the cooling mechanism failed, leading to a meltdown. that is passively cooled and uses natural cooling methods. One such design is a high-temperature reactor with a pebble-bed module .

The approach has previously been demonstrated in prototype reactors built in Germany and China but a full-scale HTR-PM reactor had yet to be attempted. has previously reported China’s ambitious push for nuclear power to reduce its dependence on fossil fuels. The Asian country has been building nuclear reactors atSuccess did not come easily either.
