Abstract
PURPOSE: To estimate changes in water level, by a method wherein an operational circuit, which finds a difference between an incoming cooling water amount to and an outgoing cooling water (steam) from a nuclear reactor, converts a ratio of the difference to a set constant into changes in water level per unit hour, and multiplies the changes by a set hour, is installed.
CONSTITUTION: For example, a steam release valve for pressureized steam in a nuclear reactor opens, and a water level changes resulting from flowing-in of cooling water from a separated cooling water pump. A signal SG1 from a cooling water meter sends an incoming amount signal to a substractor 5 through a signal processor 1, and an operational amplifier 4. In the meantime, a signal S7 from the release valve sends an outgoing (liquid) amount signal, corresponding to an exhaust steam amount, through a processor 2 and the operational amplifier 4. A difference signal between the incoming and the outgoing amount is outputted to a divider 6, and a change amount in a water level per unit hour is sent to a multiplier 8. The change amount is multiplied by a set time sent from an elapsing time setter 10, and then, an estimated value for changes in the water level is outputted to an indicator 9.
