Problems solved by technology

However, the experimental device can only measure the pressure value, and cannot directly measure the pressure difference between the sub-channels, and the direction of the pressure introduction holes is exactly the same, so the pressure value of one sub-channel can only be measured at a time

Abstract

The invention discloses a subchannel sliding type lateral pressure drop measurement system, which relates to the technical field of sliding type subchannel lateral pressure drop measurement, including a subchannel lateral pressure drop measurement device, a three-dimensional displacement platform and a clamping device, and a micro pressure difference meter and data acquisition systems. The sub-channel transverse pressure drop measuring device includes a rod bundle, an outlet water tank, a flow channel and an inlet section; the rod bundle and the outlet water tank are sealed with a threaded connection and a sealing ring, and the outlet water tank and the flow channel are sealed. A flange connection and a sealing ring are used for sealing between the passages, and a flange connection and a sealing ring are used for sealing between the flow passage and the inlet section. The invention can directly measure the pressure difference value between the sub-channels, can simultaneously measure the pressure difference value between two adjacent groups of sub-channels, and can measure at different cross-sections in the vertical direction 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 ...
