Title: Control rod operation system
Inventor: KINOSHITA MITSUO
IPC: G21C7/08
Filed: 1987-12-16
Abstract: PURPOSE:To exactly automatically judge that a nuclear reactor is either in a subcritical state, or just before a critical state, or in a critical state by using both quantities of a state of a reactor cycle measured in the nuclear reactor and the estimation of a control rod drawing position at which the nuclear reactor becomes the critical state. CONSTITUTION:A first means estimates a control rod drawing position at which a nuclear reactor becomes a critical state. The estimated value of a control rod drawing position at which the nuclear reactor becomes the critical state on the estimation of the first means nearly agrees with the real value of the control rod drawing position and further for the first time a second means finds that the nuclear reactor reaches the critical state when the reactor cycle measured in the nuclear reactor satisfies the condition of a critical judgement. Since the result in which a reactor state is judged by the second means is shown on a display by a third means, the work load of operations can be reduced. Since in the second means the judgment is which the nuclear reactor is either in the subcritical state or in a critical near-by state just before the critical state is performed in accordance with both the quantities of the state of the estimated value of the control rod drawing position at which the nuclear reactor becomes the critical state and the reactor cycle, an error of the judgement of the nuclear reactor state is not made.

Filed: 1987-12-15
Abstract: PURPOSE:To save a circuit for the countermeasures against spurious radiation to be outputted to the output and to reduce the spurious radiation component included in the output signal by applying negative feedback to the output signal automatically. CONSTITUTION:A gate 3G of a P-channel transistor(TR) 3 and a gate 34 of an N-channel TR 4 are connected to an input terminal 1 and sources 3S, 4S are connected to an output terminal 2. With a low power supply level given to the input terminal 1, for example, if the output voltage is dropped and the gate-source voltage of the P-channel TR 3 is smaller than a threshold voltage Vthp of the TR 3, the P-channel TR 3 is turned off. That is, negative feedback is applied to the output at this point of time and the output reaches a voltage at a balanced point a little higher than the Vthp. Thus, the spurious radiation component included in the output signal is reduced and a circuit such as disturbance countermeasure circuit to other devices can be saved.
