Fast initial response nuclear reactor control system
Abstract
Abstract A control system for boiling moderator-coolant nuclear reactors giving fast response to load changes is disclosed. In this system, the broad operating level of the reactor is set by adjusting the control rods. Then, the reactor operating level is adjusted to follow load requirements by changing the coolant recirculation flow rate. In order to provide fast initial response to rapid load changes an arrangement is provided cooperating with the recirculation flow control to lower the pressure regulator set point when steam demand increases so that reactor internal pressure is temporarily decreased causing increased steam generation due to flashing and sending more steam to the load. A cooperating bypass system is provided to accommodate large sudden decreases in the load steam requirements.
