Вибір основних конструктивних параметрів парогенераторів для АЕС малої потужності

Abstract

Designs and methods for calculating a steam generator (SG) for low power NPPs are considered. As a prototype adopted SG nuclear power plant type KLT-40C (RF). The general list of work in the design of SG is given. A methodology for the structural calculation of SG with a coil heating surface, as well as a mathematical model of SG, have been developed, including structural, thermal, hydraulic, strength and economic calculations. The derivation of formulas for determining the wall thickness of heat transfer tubes (HTT) and the number of concentric layers of coils is described. The methodology for determining the main dimensions of the vessel, shaft and flat cover. Using the developed computer program, the optimal diameter of the HTT, the distances between the heat transfer tubes in the layer and between the layers, the feedwater speed at the inlet to the heat transfer tubes were determined. © 2019, National Science Center, Kharkov Institute of Physics and Technology.
