Today, 39 years ago, on October 7, 1986 (Calendar, September 4, 1986), the United States invented a nuclear reactor explosion prevention device. On October 7, 1986, Xinhua News: Recently, American researchers invented a nuclear power plant that can prevent the reactor from exploding when it fails. It is that the reactor explosion is caused by the concentration of hydrogen. The more hydrogen in the reactor's fuel bar is made with uranium, the greater the danger of the reactor's explosion, and when it is overheated with water or steam, it inevitably produces hydrogen. In high-temperature conditions, the atoms of uranium and oxygen in the water molecule are oxidized, becoming uranium oxidized, and the atoms in the water molecule are
