Miniature steam generator thermal hydraulic analysis testing system

Abstract

The invention discloses a miniature steam generator thermal hydraulic analysis testing system, and belongs to the technical field of nuclear power station steam generator equipment. The miniature steam generator thermal hydraulic analysis testing system comprises a first loop unit, a second loop unit, a steam generator and a data acquisition unit. The first loop unit and the second loop unit are connected with the steam generator through pipelines, and fluid in the first loop unit can be used for heating fluid in the second loop unit. The data acquisition unit is used for acquiring the temperature, pressure and flow of fluid of the first loop unit and the second loop unit and flowing into steam generator, the first loop unit heats cooling water by means of a heat regenerator and a heating water tank which replace a nuclear reactor being of a complex structure. With respect to the first loop unit and the second loop unit, heat regenerators are employed to lead in a regenerative cycle, energy is saved, and the energy utilization rate of the system is increased.

Description

technical field [0001] The invention belongs to the technical field of steam generator equipment in nuclear power plants, and in particular relates to a thermal hydraulic analysis test system for a small steam generator. Background technique [0002] The nuclear power steam generator is an important operating equipment of a double-circuit nuclear power plant, and is the hub connecting the primary and secondary circuits. Whether the nuclear power plant can be put into operation safely and efficiently depends to a large extent on the working status of the steam generator. In the nuclear island, the energy of nuclear fission is transferred to the heat carrier of the primary circuit, and enters the steam generator through the action of the main circulation pump, and generates steam after heat exchange with the feed water of the secondary circuit in the steam generator, and after steam-water separation, The qualified steam is sent to the steam turbine. Therefore, the steam gener...

AI Technical Summary

Problems solved by technology

However, the actual steam generator has a large internal pressure, a large number of heat transfer tubes, and a complex structure. At the same time, the heat of the primary coolant comes from the nuclear reactor, which has a complex structure and strong radioactivity.

These factors have brought difficulties to build a steam generator test bench
