| Abstract [eng] |
The results of computational analysis of hydraulic characteristics of the fast acting motor valves are presented in this paper. The significant difference is identified between calculated characteristics of the change of the valve’s pressure loss coefficient during the valve’s opening/closure process in respect to those used as default approach in codes for thermal-hydraulic calculations of nuclear reactors. The change of valve’s hydraulic resistance at the very beginning of an accident causes the reduction of coolant flow rate delivered from the emergency core cooling system, abatement of core cooling intensiveness and the increase of maximal temperature of fuel element surface. |
