The Hydraulic Control Rod Drive Technology (HCRDT) is a newly invented patent of the Institute of Nuclear and New Energy Technology, Tsinghua University with 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. Based on the abnormal conditions occurring in the operation of the Control Rod Hydraulic Drive System, the electromagnetic field of the direct action solenoid valve is analyzed using the ANSYS software. The result shows that the incorrect use of the magnetic material causes the change of magnetic circuit and the reverse of the magnetic force direction in some conditions, which leads to the malfunction of the solenoid valve and the Control Rod Hydraulic Drive System. Further more, the design of the direct action solenoid valve can be optimized by the analysis of electromagnetic field.
