I'm talking about diluting the radioactive material to the point where it no longer poses the danger of generating hydrogen gas explosions. It seems to me that a large mass of metal would accomplish this before a breach in the outer containment vessel occurred. A similar process happened in the meltdown of the Chernobyl reactor, though it melted through the concrete and rock until it was diluted enough to solidify. | |

| Aug 14, 2013 at 23:59 | comment | added | cassius | 1) I'm not talking specifically about fukushima. If the process worked, it could be designed into future reactors or retrofitted in current ones. 2) It seems to me this would work much better for mitigating residual heat than simply pumping in more water. | |
| Aug 14, 2013 at 23:43 | comment | added | RedGrittyBrick | The obvious difficulties are 1) Fukushima style reactors don't have any obvious mechanism for introducing iron into the reactor. 2) The problem at Fukushima was not stopping the nuclear fission of the fuel but in removing residual heat in the absence of power for the cooling systems. | |
