Dubbed “corium”, this molten mass is both extremely dangerous and has the potential to move. When a nuclear plant undergoes a catastrophic meltdown, a radioactive lava-like mixture of nuclear fuel, control rods, fission products and the reactor’s structural components can form. The developers are now working toward a commercial application of the system. The technique involves using granular carbonate materials rather than water and has been demonstrated in both small and large-scale testbeds using molten lead oxide. (Courtesy: Randy Montoya)Ī new way of cooling and containing the radioactive, lava-like mass that forms in the core of a nuclear reactor during a catastrophic meltdown has been developed by researchers in the US.
