It seems that the water is fixed, and the heater voltage is varied to find the equilibrium. This is assumed to be the "danger" associated with a feedback cicuit (loss of control). Running at a "self-sustaining" level (i.e., so reactive that no input is necessary) could result in thermal runaway above stasis, and no control mechanism (other than increasing the water flow) to bring the temperature back down. The reactor was producing more power in the previous experiments, so they increased the pump rate. It has a fixed displacement per stroke, but is variable in strokes/min. This is the theory, anyway. The jury is still deliberating.
