Fourth A-CINCH webinar „Safety of future reactors (Gen IV) – A story from the past and present“

Safety of future reactors (Gen IV) – A story from the past and present 

Prof. Teodora Retegan Vollmer 

Department of Chemistry and Chemical Engineering  

Chalmers University 

Moderator: Prof. Mario Mariani, Politecnico di Milano   


 The purpose of the presentation is to give insight into the reactor safety from a chemical point of view for Gen II-III and Gen IV Reactors. The physical barriers set up for a safe functioning of a nuclear reactor are (generally): the fuel matrix, the cladding, and the coolant (light or heavy water, gas, molten metals like Lead-Bismuth eutectic or LBE, Pb, other for the more advanced systems) as well as the reactor vessel, primary containment and the secondary containment. Each barrier and the chemical processes accompanying the potential release of radionuclides (or retention) will be briefly explained and the overall aim is to give a general view over the processes governing the release path for radionuclides, as well as the mitigation measures.
