Abstract

A nuclear-power-plant computer-based procedure display device is disposed in a main control room of a nuclear power plant, and includes a operating procedure storage unit that stores a computer-based procedure in which plant operation procedures of the nuclear power plant are divided into procedure steps and listed, a operating procedure display unit that displays the computer-based procedure, and a operating procedure display control unit that controls display of the computer-based procedure. In a case where the procedure step displayed on the operating procedure display unit is selected by an operator, the operating procedure display control unit displays an indication that the procedure step is selected, on the operating procedure display unit.

First claim

1 - 15 . (canceled)

16 . A nuclear-power-plant computer-based procedure display device which is disposed in a main control room of a nuclear power plant, comprising:
a operating procedure storage unit that stores a computer-based procedure in which operation procedures of the nuclear power plant are divided into procedure steps and listed; a operating procedure display unit that displays the computer-based procedure; and a operating procedure display control unit that controls display of the computer-based procedure, wherein in a case where the procedure step displayed on the operating procedure display unit is selected by an operator, the operating procedure display control unit displays an indication that the procedure step is selected, on the operating procedure display unit, and displays a first color indicating an unexecuted state in which the procedure step is not executed, a second color indicating an execution state in which the procedure step is being executed, a third color indicating an end state in which the procedure step is ended, or a fourth color indicating a non-applied state in which the procedure step is not applied, by performing switching between the colors, based on the selection by the operator, on the operating procedure display unit.

17 . The nuclear-power-plant computer-based procedure display device according to claim 16 ,
wherein in a case where selection of the procedure step is detected, the operating procedure display control unit displays an indication that the procedure described in the procedure step has been executed, as the indication that the procedure step is selected, on the operating procedure display unit.

18 . The nuclear-power-plant computer-based procedure display device according to claim 16 ,
wherein the operating procedure display control unit acquires a current value of a parameter of the nuclear power plant related to the procedure step, and displays the acquired current value of the parameter in association with the procedure step, on the operating procedure display unit.

19 . The nuclear-power-plant computer-based procedure display device according to claim 16 ,
wherein the operating procedure display control unit specifies the operator who selects the procedure step, and stores information on the operator who selects the procedure step in association with the selected procedure step, in the operating procedure storage unit.

20 . The nuclear-power-plant computer-based procedure display device according to claim 16 ,
wherein the operating procedure display unit is a touch panel having a procedure step display area in which the procedure step is displayed, and wherein in a case where the procedure step display area is touched by the operator, the operating procedure display control unit displays an indication that the procedure step displayed in the procedure step display area is selected, by changing the color of the procedure step display area which is touched.

21 . The nuclear-power-plant computer-based procedure display device according to claim 16 , further comprising:
a plurality of the operating procedure display units each of which displays the computer-based procedure of the same content, wherein the operating procedure display control unit specifies an operator based on the login information of the operator, and in a case where the procedure step displayed on any of the operating procedure display units is selected by the operator, the operating procedure display control unit also displays an indication that the procedure step is selected, on other operating procedure display units.

22 . A nuclear-power-plant safety control and monitoring system which is disposed in a main control room of a nuclear power plant including a plurality of safety devices which are used when abnormality occurs, and have the same function as each other, comprising:
a parallel parameter monitor control unit that displays safety parameters which are current values of the parameters of the safety device, for each type of the safety parameters and for each of the plurality of safety devices, side by side; and a task-based parameter monitor control unit that displays the safety parameters, for each step of an emergency operation procedure which is a procedure for leading to a safe state and for each of the plurality of safety devices, side by side, wherein the parallel parameter monitor control unit distinguishes and displays a safety parameter that does not have a normal value or is not in a normal state from a normal safety parameter, among the safety parameters.

23 . The nuclear-power-plant safety control and monitoring system according to claim 22 , further comprising:
a safety parameter monitor device including the task-based parameter monitor control unit, and a safety parameter display unit that displays the safety parameters under the control of the task-based parameter monitor control unit; and a safety control device including a task-based control unit that controls the operation of each unit of the safety device when executing the emergency operation procedure, wherein the task-based parameter monitor control unit displays parameters of a safety device related to a procedure step of an emergency operation procedure executed by the task-based control unit as the safety parameters, on the safety parameter display unit.

24 . A nuclear-power-plant operation monitoring system which is disposed in a main control room of a nuclear power plant, comprising:
a display panel which is disposed at a position visible to all workers in the main control room, and displays a main parameter image which is a display of main parameters of the nuclear power plant is associated with the positions in the nuclear power plant, and an abnormal parameter image which is a display of an abnormal parameter of which the value is abnormal, out of the main parameters; and a non-safety control device including a non-safety control unit that controls the operation of the nuclear power plant based on the operation of the worker, and a non-safety control display unit that displays an image under the control of the non-safety control unit, wherein the non-safety control unit displays an initial window including the main parameter image and the abnormal parameter image, on the non-safety control display unit, in conjunction with the display on the display panel, and activates a control program of the nuclear power plant related to the abnormal parameter, in a case where the display of the abnormal parameter in the initial window is selected by the worker.

25 . The nuclear-power-plant operation monitoring system according to claim 24 ,
wherein in a case where the abnormal parameter, to which a plurality of the control programs are related, is selected in the initial window, the non-safety control unit displays a program selection window that displays the plurality of control programs on the non-safety control display unit, and in a case where display of one control program is selected in the program selection window, the selected program is activated.

26 . The nuclear-power-plant operation monitoring system according to claim 24 , further comprising:
a supervisory control device that a supervisor who supervises the workers operates; and a supervisory auxiliary display device which is disposed adjacent to the supervisory control device, and performs the same display as the display on the non-safety control display unit.

27 . A nuclear-power-plant operation monitoring system which is disposed in a main control room of a nuclear power plant, comprising:
a display panel which is disposed at a position visible to all workers in
