Method and device for controlling reactor pressure
- 1. Hitachi Ltd., Tokyo (Japan)
Description
Purpose: To enable automatic pressure control even under the non-critical status. Constitution: A reactor pressure control device is provided in addition to a turbine pressure control device. The pressure control for a nuclear reactor is performed by the turbine pressure control device in which a reference pressure valve signal is set and the reactor pressure control device which compares the reference pressure signal and an actual pressure and outputs a pressure setting signal to the turbine pressure control device. Specifically, a main steam pressure signal from a pressure detector and a pressure signal set to the turbine pressure control device are inputted to the reactor pressure control device and compared with each other to calculate a proper pressure setting signal, which is outputted to the turbine pressure control device for the actual pressure control.
