As Masurium, it was the first element discovered that occurs in nature only from spontaneous fission, and as Technetium, it was the first element discovered in a laboratory.
The majority radioactive fission products of the spent fuel elements in high temperature gas-cooled reactor(HTGR) is contained in the fuel element.
高温气冷堆乏燃料元件的放射性裂变产物绝大部分滞留在燃料元件中。
