Pseudocritical Rapid Energy Dissipation Analysis of Base-Load Electrical Demand Reduction on Nuclear Steam Supply System

Effect of pseudocritical rapid energy dissipation (PRED) from Pressurizer in nuclear steam supply system Pressurized Water Reactor, where a single event as common cause failure, considerable reduction base-load electricity demand causes the temperature reactor coolant (RCS) to increase, and corresponding pressure increases pressurizer generators above set-points. The study employed uses MATLAB/Simulink library tools, experimentally modelled control PRED, momentum transport kinematic viscosity fraction point dissipated excess energy, maintain safety RCS keep water boiling. result demonstrated significance vector Prandlt number heat transfer coefficients that provided detailed activities 2-D contour 3-D graphics specific internal other parameterization fluid pressurizer.
