Non-Linear Equation of Motion of an LPM Type CRDM and Phase Plane Solutions
- 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)
Description
An LPM (Linear Pulse Motor) type drive mechanism is the one of the candidates for CRDM (Control Rod Drive Mechanism) of an integral reactor SMART (System-integrated Modular Advanced ReacTor). The LPM type CRDM has four sets of electric magnets in it, which are operated in sequences to move the reactivity control elements upward or downward. The absence of any mechanical parts reduces the mechanical losses and makes the responses faster. However, since the total weight of the moving part is held by electric magnet forces only, careful consideration regarding the stability of the driving system is required in design stages to prevent undesirable disturbances in driving procedures and by external dynamic loads. A non-linear equation of motion of the LPM type CRDM is derived and the solutions on phase plane are studied
