Nuclear motor performance verification device

Abstract

The invention discloses a nuclear motor performance verification device, which comprises a closed pressure container, namely LOCA furnace, a nuclear motor, a load, and an intermediate transmission assembly, wherein the LOCA furnace is used for simulating thermodynamics and chemical environment in the safety shell of a nuclear power plant and comprises a closed space formed by an upper plug, a lower plug and a barrel; the nuclear motor is fixedly arranged in the LOCA furnace; the load is arranged outside the LOCA furnace; and the intermediate transmission assembly is inserted into the barrel body of the LOCA furnace for connecting the nuclear motor and the load, and the nuclear motor drives the load to work. The device can verify the performance of the nuclear motor under specific thermotechnical and chemical conditions, and at the same time, reduce equipment damage and improve the utilization rate of equipment.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a performance verification device for a nuclear motor. Background technique [0002] According to the requirements of nuclear safety regulations, in order to ensure the safe operation of nuclear power plants under normal operating conditions, nuclear accident conditions and post-accident conditions, and to protect public health and safety, a series of identification tests must be carried out on nuclear safety systems and equipment , verifying that it can perform its intended function. For nuclear motors, it is necessary to simulate the performance test under thermal dynamic and chemical conditions during the accident in the containment. Capability to operate loads in specific thermal dynamic and chemical environments. [0003] The existing nuclear motor load test mainly adopts two methods, one is: in the natural environment of normal temperature and pressure, the motor (nuclear mot...

AI Technical Summary

Problems solved by technology

In the process of implementing the present invention, the inventor found that in the above two solutions, there are the following disadvantages: the motors are all in a natural environment at normal temperature and pressure, and only the operating data at normal temperature and pressure can be obtained, but cannot be obtained. The performance data of its operation under specific thermodynamic and chemical conditions; in addition, since the motor is directly connected to the load, during the transmission process between the motor and the load, the transmission bearing of the motor needs to bear bending moment and axial force torque, and the rolling bearing of the motor is It needs to withstand axial force and radial force, so it will definitely cause damage to the equipment (nuclear motor)
