Abstract

Abstract

Fuel assembly loading and unloading is an important operation of nuclear power plant reactor refueling maintenance. Because of its special operating environment, the loading and unloading positioning accuracy of floating nuclear power plant is higher. Based on the tolerance modeling method of small displacement torsor (SDT), this paper analyzes the guidance and positioning error of reactor loading and unloading in floating nuclear power plant. Using the method of rigid body dynamic coordinate system transformation, the expression of loading and unloading positioning error is obtained; the simulation calculation is carried out using MATLAB program. The limit inclination of reactor loading and unloading under marine conditions is analyzed, and the relationship between the maximum inclination and wave parameters is given. The key parameters such as the guide clearance of the fuel assembly are optimized, and the results are compared with the experimental data, which are in good agreement.
