摘要

Hydraulic Control Rod Drive Technology (HCRDT) is a newly invented patent and Institute of Nuclear and New Energy Technology Tsinghua University owns HCRDT's independent intellectual property rights. The integrated valve which is made up of three direct action solenoid valves is the key part of this technology, so the performance of the solenoid valve directly affects the function of the integrated valve and the HCRDT. First, based on the conditions occurring in the operation of the Control Rod Hydraulic Drive System, the coil of the direct action solenoid valve in high temperature is studied by the experiment and the temperature of coil under different temperature can be obtained. Second, the temperature field of the coil is analyzed by ANSYS in order that the thermal conductivity of coil under different temperature can be obtained. Third, the temperature field of the integrated valve is analyzed by CFX based on the thermal conductivity. The result shows that the current is the key point which affects the temperature of the valve most and the valve cannot work regularly if the current is too high. Finally, the working condition of the solenoid valve is optimized, especially the current, so that not only the temperature of the coil is under its decomposition temperature and but also the valve can work efficiently.
