| titleOfInvention | Calcium phosphate based sacrificial material of core catcher against nuclear reactor core melting accident and sacrificial concrete composition containing same |
| abstract | The present invention relates to a calcium phosphate-based sacrificial material for a core catcher and a sacrificial concrete composition containing the same compared to a nuclear reactor core melting accident, and more particularly, phosphoric acid having excellent high-temperature reactivity for cooling an external core melt that may be ejected during a nuclear reactor core accident. It relates to a calcium-based sacrificial material and a sacrificial concrete composition comprising the same. As the present invention applies any one or more of phosphates, hydrogen phosphates, and phosphate hydroxides having a composition molar ratio of calcium (Ca) and phosphorus (P) of 1 to 2 Unlike the previously developed sacrificial material using exothermic reaction, the endothermic reaction in which various phosphates are synthesized together with the core melt is induced, so that the temperature of the core melt can be lowered, and the generation of flammable hydrogen gas can be reduced when cooling water is introduced. To do that is the technical point. |
