Problems solved by technology

However, there is currently no special equipment for operators to practice or develop and test special tools. As a result, what the maintenance personnel have learned is still at the theoretical stage, which is seriously separated from actual operation, so it is difficult to meet the above requirements

Abstract

The invention discloses a steam generator test system, which comprises a shell, a lower assembly, an upper assembly, a supporting assembly and an operation platform, wherein the top part and the middle part of the shell are respectively provided with a steam outlet nozzle and a water supply inlet, and the bottom part is provided with a coolant inlet and a coolant outlet; the lower assembly comprises a heat transfer tube arranged in the shell and a tube bundle sleeve arranged outside the heat transfer tube, two ends of the heat transfer tube are respectively communicated with the coolant inlet and the coolant outlet, and the tube bundle sleeve separates the shell into a falling channel and a rising channel communicated; the upper assembly comprises a water supply loop tube, a steam-water separator and a drier sequentially arranged above the tube bundle sleeve, and the water supply loop tube is communicated with the water supply inlet; the supporting assembly is fixedly connected onto the bottom part of the shell for supporting the shell; and the operation platform is arranged outside the shell for training and operation. The test system can meet demands on special tool development and test and personnel training, skill proficiency of a maintenance person can be ensured, and damage to the steam generator or person radiation pollution in the case of actual operation can be avoided.

Description

technical field [0001] The invention relates to the technical field of pressurized water reactor nuclear power plants, in particular to a steam generator test system suitable for developing, testing and training special tools. Background technique [0002] In the pressurized water reactor nuclear power plant, the steam generator is one of the three major equipments in the nuclear island, and it is the hub connecting the primary circuit system and the secondary circuit system. [0003] The primary loop system includes at least the reactor pressure vessel, the steam generator and the hot section and the cold section of the main pipeline connected between them, and the cold section of the main pipeline is also equipped with a main pump. The reactor core heats the feed water due to the huge heat energy generated by nuclear fuel fission. The high temperature and high pressure feed water takes the heat energy generated by the reactor core out of the reactor pressure vessel and ent...
