摘要： PURPOSE:To enable saving of time elapsing before a rated power is achieved by raising an output through control rod withdrawal and control of recirculation flow rate, by lessening raising step width of the output through the control of recirculation flow after a control rods pattern for a rated output is achieved, thereby quickening accumulation of xenon. CONSTITUTION:After an output is raised by control rod withdrawal, upto a level where recirculation flow rate can be allowed, both the control rod withdrawal and increment of recirculation flow rate are parallelly conducted within a range which does not exceed thermal limiting values of a fuel. When the recirculation flow rate reaches an upper limit or a predetermined value, the output is raised by the control rod withdrawal, and when there remains no mirgin to the thermal limit value, control rod operation is interrupted. After waiting the mirgin to be expanded by means of decreasing of the output or by accumulation of xenon, the control rods are again withdrawn, and thereafter when a pattern with which a rated output can be obtained, by repeating those procedure, the rated output is achieved by increment of the recirculation flow rate. After that, the control rods are gradually withdrawn according to the accumulation level of xenon, in order to achieve a target pattern.

摘要： PURPOSE:To realize a protective safety operation of plant upon occurrence of abnormality by providing a section for deciding an abnormality based on various signals from a nuclear power plant, and a section for predicting the operating state of the plant, producing a protective operation command for avoiding stoppage of plant, and then delivering an operation command. CONSTITUTION:The plant protective system 13 takes in various signals from a plant through an abnormality deciding section 14 and a predicting section 15. When such a decision is made that the state of plant is abnormal at the section 14, a countermeasure deciding section 16 predicts and decides a necessary countermeasure operation based on abnormality decision information and predictive information from the section 15. Upon receiving an abnormality decision signal of pump trip at a turbine driven water supply section from the section 14 and predictive information of reduction of water supply to half from the section 15, the section 16 lowers the output of a nuclear reactor depending on the water supply through a countermeasure operation command section 17. Alternatively, protective operation can be effected by deciding whether the countermeasure operation should be effected at a control period or it can be started with some lag.

摘要： PURPOSE:To achieve higher operating rate by correcting an inserting position of a control rod during the calculation of a limit output ratio and at the present and a operation restriction value calculated as function of a flow rate of a core to be compared with an LPRM signal inputted from a plant and the operation restriction value respectively. CONSTITUTION:Process data (control rod pattern, core flow rate, LPRM signal and the like) are inputted into a core performance calculator 2 from a nuclear reactor 1 when calculation cycle is reached to calculate a limit output ratio as restraint conditions imposed on a fuel and then, the limit output ratio and the process data are transferred to an operation restriction value calculator 3, with which 3 a restriction value for monitoring the minimum limit output ratio is determined from the data to be transferred to an operation restriction value corrector 8. Then, with the device 8, the operation restriction value calculated with the device 3 is corrected to be applicable for the state of a core at a monitoring to be transferred to the minimum limit output ratio monitor 9. With the device 9, the LPRM signal is inputted from the nuclear reactor 1 through a control rod drive system 10 and a recirculation flow rate system 11 to be compared with the operation restriction value calculated with the device 8 to block the operation of the control rod.

摘要： PURPOSE:To allow the presentation of adequate control procedures to an operator by making prediction by using an online reactor core simulator concerning an output change control and previously preparing an alternate control for the control having no allowance in restriction conditions. CONSTITUTION:The output change procedures are read in from a memory device 5 and the control to be executed next is determined by comparing the procedures and the state quantity of the plant in a control selector 6 when the output change control is started. This control is sent to a control predicting device 7 which predicts the core state at the time when this control is executed by using the result of the prediction made by a preliminary predicting device 1'. This control is sent to an input/output device 1 and is guided to the operator when the results of the prediction satisfy the limitation conditions. An alternate control selector 9 is started to select the alternate control satisfying the limitation conditions from the predicted 4 alternate control when the results of the prediction are evaluated 7 as not to satisfy the prediction conditions. The selected control is sent to the device 1 and is guided to the operator. The core state after the control is kept monitored by using the results of the prediction of the device 1' by a control monitoring device 8 when the operator executes the guided control.
