In general, if we lower the control rods, the rate of nuclear reactions decreases. The control rods are neutron absorbers, and lowering them will push them into the upper area of the core where fissions are occurring. The neutrons released during these fission events may be absorbed by the control rods that have just been lowered into the vicinity. This will cause the rate of fission to go down.
