A Cooling Test of Improved CEDM Coil Stack Assembly
- 1. KEPCO Engineering and Construction, Daejeon (Korea, Republic of)
Description
The main function of the CEDM(Control Element Drive Mechanism) coil stack assembly is to generate proper electro-magnetic field in order to draw, insert, or hold the control rod assembly at any position. During the plant normal operation, the CEDM coils are primarily heated by the motor housing that constitutes a reactor coolant pressure boundary, and additionally heated by the operating coil current. Under these conditions, therefore, it is very important to prevent thermal damages of the coils which can cause the control rod drop. In fact, there had been some cases of the control rod drop related to the thermal deterioration of the CEDM coils in the existing nuclear power plants. As a part of APR plus(Advanced Power Reactor plus) development project, the CEDM coil as well as the CEDM has been studied to have less heat generation than present coil
