Abstract

The invention discloses a steam generator simulation body water supply system used in the heating and boosting process and a control method. The water supply system comprises a steam generator simulation body, a water supply voltage stabilizer and a condenser. The water supply voltage stabilizer communicates with the steam generator simulation body through a water inlet pipe. The steam generator simulation body communicates with the condenser through a steam pipe. A water feed pump is arranged on the water inlet pipe. The outlet end of the condenser communicates with the inlet end of the waterfeed pump through a cold water pipe. A frequency conversion multi-stage centrifugal pump is adopted as the water feed pump. A bypass branch pipe of the water feed pump is arranged on the water inletpipe in parallel. A heat regenerator is arranged on the water inlet pipe and located at the rear end of the water feed pump. The outlet end of the heat regenerator communicates with the inlet end of the condenser. The inlet end of the heat regenerator communicates with the outlet end of the condenser. Flow meters and regulating valves are arranged on the water inlet pipe, the steam pipe and the bypass branch pipe correspondingly.

Description

technical field [0001] The invention relates to the field of nuclear reactor safety-related test and research equipment, in particular to a water supply system and a control method for a steam generator simulation body in the process of temperature rise and pressure rise. Background technique [0002] In nuclear power reactors and secondary loop systems, two sets of steam generator water supply systems are generally used: the main water supply system and the start-up water supply system. During the start-up process of temperature rise and pressure increase, the start-up water supply system is used to provide feed water for the steam generator to maintain a positive water level on the secondary side of the steam generator; after the normal working conditions are established, the main water supply system is put into operation to provide feed water for the steam generator. The main water supply system and the start-up water supply system jointly ensure the water supply requirem...
