The invention discloses a slipping type sub-channel lateral pressure drop measurement system, and relates to the technical field of slipping type sub-channel lateral pressure drop measurement. The system includes a sub-channel lateral pressure drop measurement device, a three-dimensional displacement platform and clamping device, a micro-pressure difference meter and a data acquisition systems. The sub-channel lateral pressure drop measurement device includes a rod cluster, an outlet water tank, a flow channel and an inlet section; the rod cluster is in threaded connection with the outlet water tank, the connecting position is sealed with a seal ring, the outlet water tank is connected with the flow channel by a flange, the connecting position is sealed with a sea ring, the flow channel isconnected with the inlet section by a flange, and the connecting position is sealed with a seal ring. The slipping type sub-channel lateral pressure drop measurement system can directly measure the pressure difference among sub-channels, can simultaneously measure the pressure difference values between the adjacent two groups of sub-channels, and can measure at different sections in the verticaldirection through height adjustment.
Description
technical field [0001] The invention relates to the technical field of pressure drop measurement, in particular to a subchannel sliding type lateral pressure drop measurement system. Background technique [0002] While nuclear power is booming, researchers are paying more and more attention to the safety issues of nuclear power plant design. We know that in a typical pressurized water reactor nuclear power plant, the core is where heat is generated. Therefore, with the upgrade of the nuclear power plant and the increase in power, can it be more effective to take away the heat of the reactor core and ensure that the temperature of the nuclear fuel assembly is not too high? It has become an important factor to be considered in the design of nuclear fuel assemblies. [0003] In conventional pressurized water nuclear reactors, the most commonly used structure in nuclear fuel assemblies is the rod bundle structure. The fuel rods are arranged according to 17×17 and fixed into a ...
