Abstract: To provide a maintenance computer and a maintenance program of a plant monitoring and control system in which engineers other than the program designer can check and change program source code part relevant to each of the input point information and the output point information. The maintenance computer performs code extracting processing that extracts source code part of program of an integration computer relevant to each of input point information inputted into controller from integration computer and output point information outputted to integration computer from controller.

Abstract: A remote integrated monitoring operation system includes: a unit integrated database for sequentially recording a name of each plant unit, a parameter indicating an event that has occurred in the plant unit, a state of the parameter, and warning classification indicated by the parameter and the state; an inter-unit influence degree evaluation database for recording influence of the event on the other plant unit; a restoration response guidance database for defining a response to the event; a per-unit urgency degree determination section for determining a degree of urgency of each plant unit; an inter-unit influence degree determination section for evaluating a degree of influence of the event on the other plant unit; and a priority determination section for determining priorities between the respective plant units from the degree of urgency and the degree of influence.

Abstract: An operating manual list file in the document format prepared by a general-purpose document preparation software is entered in an apparatus for preparing an operating manual list and the operating manual list file is converted from the document format into the XML format. Subsequently, the operating manual list file converted into the XML format is substituted with the CBP XML format suitable for the CBP. Finally, the suitability of the substitution of the operating manual list file substituted with the CBP XML format is determined, and, if needed, the modification is made. As a result, the preparation of the operating manual list file in the format suitable for the plant display is completed. Thus, the operating manual list file prepared in a universal document format is used to prepare an operating manual list file suitable for the display format of a display of a plant.

Abstract: A system for supporting nuclear power plant operation includes an event data base that stores events corresponding to behaviors of the plant data. A countermeasure operation database stores operations corresponding to the events. An operation procedure database stores operation procedures that are required for the corresponding operations. An event discriminating section retrieves an event that occurs in a nuclear power plant from an event database so as to discriminate based on a behavior of plant data that is captured from the plant interface. A countermeasure retrieval section retrieves a countermeasure operation from the countermeasure operation database based on an event that is discriminated by the event discriminating section. A display control section displays an operation procedure that is required for performing the countermeasure operation on a display device.
