Theoretical Model on Stepping Process of the Hydraulic Control Rod Driving System

The purpose of this paper is to theoretically expound the working mechanism of the new technology of the hydraulic control rod driving system(HCRDS), and also establish the theoretical model for further analysis and research. The working principle of the HCRDS has been introduced in this paper, also given are the theoretical model and its mathematical description of the HCRDS’s stepping process. The compare between the result of this model and that of the experiment proves the rationality and feasibility of it.
