FMEA of Control Rod Drive Mechanism Control System
Each control rod bank is divided into two or more groups to obtain smaller incremental reactivity changes per step. The control rod groups within the same bank are moved such that the relative position of the groups does not differ by more than one-step. Each control rod in a group is paralleled so that rods of the same group move simultaneously.
