Problems solved by technology

[0002] Most of the pellets involved in the prior art are nuclear fuel pellets, which are processed into cylindrical shapes, and their density needs to be measured. Now, the volume and mass are generally measured, and finally the density is calculated. In volume measurement, the pellets are put into the liquid , using the height difference of the liquid to calculate the volume, but this situation will damage the surface of the pellet that is in contact with the measurement liquid, and affect the use of the pellet to be measured. This method is also very cumbersome and complicated to operate

Description

technical field [0001] The invention relates to the field of fuel pellet measurement, in particular to a cylindrical pellet density measurement device and a measurement method thereof. Background technique [0002] Most of the pellets involved in the prior art are nuclear fuel pellets, which are processed into cylindrical shapes, and their density needs to be measured. Now, the volume and mass are generally measured, and finally the density is calculated. In volume measurement, the pellets are put into the liquid , using the height difference of the liquid to calculate the volume, but this situation will damage the surface of the pellet that is in contact with the measurement liquid and affect the use of the pellet to be measured. This method is also very cumbersome and complicated to operate. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a cylindrical pellet density mea...
