INVESTIGATION OF THE POSSIBILITY OF REMOVING THE MELT OF MATERIALS IN THE ACTIVE ZONE OF A NUCLEAR REACTOR ALONG THE GUIDE TUBE OF A CONTROL ROD

Abstract

The article discusses the possibility of safely realizing a reactor experiment with an experimental device (EC) to study the possibility of removing the melt materials of the core in the lower plenum of a fast neutron reactor. The sequence of the planned events of the experiment was analyzed. In the ANSYS software package, a computational model has been developed and the thermal state of the EC has been analyzed both in the normal mode of the experiment and in the case of an emergency. The time of the beginning of the melting of the fuel assembly shell is shown, the heating temperatures of the EU power case, which do not exceed the permissible norms, are considered. It has been revealed that in the event of an emergency, the integrity of the design of the cover of the fuel assembly and the EC buildings are preserved.
