Experimental Study and Analysis of the Deformable Pipe of CRHDM

Abstract

Hydraulic Control Rod Drive Technology (HCRDT) is a newly invented patent owned by Institute of Nuclear and New Energy Technology Tsinghua University with independent intellectual property rights. The hydraulic cylinder which is connected by the deformable pipe is the key part of this technology, so the performance of the deformable pipe directly affects the function of the hydraulic cylinder and the HCRDT. Based on the conditions occurring in the operation of the Control Rod Hydraulic Drive System, a kind of new deformable pipe is designed and has been tested by the experiment and analyzed by ANSYS. The result shows that the longer deformable pipe is the longer its lifetime is firstly. Second, lifetime of the deformable pipe which has net is longer. Furthermore, the design of HCRDT can be optimized.
