Inverse-balance element analysis for the secondary circuit of a pressurized water reactor-based nuclear power plant

On the basis of analyzing the effect of additional components on the incoming water factor of a heating unit derived is a general expression for the incoming water factor of the high-pressure heating unit of a secondary circuit. Through a detailed theoretical analysis and mathematical deduction an inverse-balance mathematical model was set up for the secondary circuit of a pressurized water reactor-based nuclear power plant. The foregoing has laid a theoretical basis for the inverse-balance element analytical method of the above-mentioned secondary circuit. Such an analytical method features a simplified calculation and an accuracy of the calculated results. Being convenient for manual calculations and programming-based electronic calculations, it represents one of the effective tools for the secondary circuit system design and energy-saving diagnosis.
