Sensitivity analysis for power plant pumping systems in breakdown

The small number of available complete modern pump characteristics makes the safety analysis of nuclear and conventional power plants based on the characteristics made over half a century ago of specific speeds nq = 24.6,147.1 and 261.4. The aim of the paper is to check sensitivity of the power plant system response for different complete pump characteristics–modern and available from older tests for nq = 24.6, 147.1 and 261.4. It has been shown that Suter’s characteristics for modern pumps give a different response to the pumping system of a power plant in break down than those used so far.
