Investigation of New Inorganic Materials for Nuclear Industry under Severe Accident Conditions

Popis výsledku v původním jazyce

Geopolymers can show superior properties than concrete in nuclear reactor severe accident applications, helping to increase safety and mitigate consequences. Scientists study geopolymers primarily for usage in radioactive waste immobilization due to their polymeric structures and advantageous properties. With these properties, such as high gamma radiation resistance, low water content, and the ability to incorporate various elements to enhance physicochemical properties, geopolymers may be sacrificial materials in GEN IV reactors. In present study we conducted a geopolymer interaction experiments with molten corium and studied the physicochemical properties at extreme temperatures to contribute to their qualification and application. Based on our research, geopolymers with Gd O additive as a neutron absorber and Fe O additive as a liquidus lowering agent of the mixture indicated as functional sacrificial materials for GEN IV reactors, exhibiting advantageous physicochemical properties for use as sacrificial material and commonly used concrete. Published in Proceedings of the 11thEuropean Review Meeting on Severe Accidents Research (ERMSAR2024).
