    摘要: A method of automatically measuring the flexure value of a wire electrode 1 in a wire-cut electric discharge machine, such that at a measurement point in the course of electric discharge machining, the electric discharge is temporarily stopped, and whether or not a wire electrode 1 and a workpiece 2 come into contact is sensed by a contact sensing device 107a. The wire electrode 1 and the workpiece 2 are moved relatively to advance or retreat in accordance with a sensed touch signal TS, and a distance .epsilon..sub.1 of movement until the contact state changes is measured. The flexure value .epsilon. is calculated from the measured movement distance .epsilon..sub.1 and the size of the discharge gap.

    摘要: In a control apparatus for residual heat removal system for a nuclear reactor in which the steam generated in the reactor vessel is cooled and condensed into water through a heat exchanger and the condensed water is fed back by a feedwater pump driven by the reactor steam so as to cool the reactor core, the pressure of the condensed water at the exit of the heat exchanger is increased with the rise of the reactor water level so as to decrease the flow of the condensed water, that is, coolant water and the flow-in of the make-up water from the make-up water reservoir communicating with the outlet port of the condenser while the quantity of the reactor steam supplied to the turbine is decreased with the increase in the reactor temperature fall rate so as to decrease the flow of the coolant water fed back into the reactor vessel.

    摘要: This invention relates to an automation system for nuclear power plants. This system comprises operation plan making means, supervisory control means, and control means for controlling controlled objects. The operation plan making means makes a new operation plan to restore a normal operating condition which existed before the plant condition deviated from the normal operation range. The supervisory control means outputs control commands according to an operation plan under abnormal condition when the plant operating condition deviates from the normal operation range. Furthermore, the supervisory control means outputs control commands according a new operation plan prepared by the operation plan making means after an operation according to an operation plan under abnormal condition has been finished. The control means for controlling controlled objects controls the controlled objects according to control commands output from the supervisory control means.
