Description
Summary:The results of complex calculation of the solution pulsed nuclear reactor (PNR) VIR-2M are presented. The simulation of the fuel solution dynamics is described, and different pulse modes implemented at VIR-2M are analyzed. The effect of cross-connecting baffles for fixing the rod channel positions with respect to the central channel of PNR VIR-2M was taken into account in calculations for the first time. The numerical model of PNR VIR-2M core vessel was constructed, and the analysis of its strain condition under the action of pulsed load determined by the fuel solution dynamics in fission pulse generation was performed. The studies prove the mechanical and strength parameters of the PNR VIR-2M vessel and substantiate its service properties.
