A condition determination system includes: an operation condition data obtaining unit that obtains operation condition data indicating an operation condition of a facility; and a determination unit that determines, based on the operation condition data, a level of a phenomenon that occurs due to the operation condition of the facility.

Condition determination system, condition determination method, decision-making support system, computer program, and storage medium

A work planning system includes an event-data acquisition unit that acquires event data indicating an event of a facility, a storage unit that stores therein a plurality of pieces of work data indicating contents of works that can be performed with respect to the facility, and a decision unit that decides each importance degree of a plurality of pieces of work data based on the event data.

Work planning system, work planning method, decision-making support system, computer program, and storage medium

An apparatus includes an image capturing device, a display, a storage, and a controller. In the storage, for an alarm window having plural lit portions that indicate alarms for plural items by lighting, position information and procedure information are stored beforehand, the position information associating a layout of the lit portions, with the respective items, the procedure information being handling procedures for the respective items corresponding to the respective lit portions. The controller displays the alarm window image-captured by the image capturing device on the display, causes an on-display position of any of the lit portions that has been lit to be selectable, and if the on-display position of the lit portion that has been lit is selected, reads out procedure information of the item corresponding to the lit portion from the storage and displays the procedure information on the display.

Operation assistance apparatus and operation assistance method

To provide a route planning system including a route-status-data acquisition unit that acquires route status data indicating a status of a basic route for moving a support facility from a standby position to a predetermined position in case of emergency of an existing facility, and a generation unit that generates alternative route data indicating an alternative route for moving the support facility to the predetermined position based on the route status data.

Route planning system, route planning method, article-arrangement planning system, article-arrangement planning method, decision-making support system, computer program, and storage medium

A display generating device includes an acquiring unit configured to acquire multiple pieces of event data, each of which being provided with time information and identification information indicating which one of multiple categories related to a facility the event data belongs to, and a generating unit configured to generate display data by arraying the multiple pieces of the event data in time series based on the time information for each of the categories depending on the identification information.

Display generating device, display control device, and display generating method

An emergency decision-making assistance system includes an information management unit operable to generate display data on the basis of emergency information and to share the emergency information via a network; a display unit operable to display a plurality of pieces of the display data generated by the information management unit; a console unit operable to switch between the plurality of pieces of display data displayed on the display unit; and a database configured to store the plurality of pieces of display data generated by the information management unit. Decision-making is thereby effectively assisted by obtaining only necessary information in a plurality of sites.

Emergency decision-making assistance system

There is provided a device for monitoring an operation of a nuclear plant, including: a functional integration VDU having a regular-use-system VDU that monitors the operation of the plant under normal conditions, and a security-system VDU that leads to a safe state when the plant is in an abnormal state; and a security-system VDU that leads to a safe state when the plant is in an abnormal state. The functional integration VDU is mounted to a first operating console, the security-system VDU is mounted to a second operating console, and thereby an increase in the size of the operating consoles in the nuclear plant is suppressed, and increased ease of operation is enabled.

Device for monitoring operation of nuclear plant

In an operation monitoring apparatus of a nuclear power plant, a first operation console () that can be operated by an operator and includes displays (to), an operation command console () that can be operated by a shift supervisor and includes displays (to) , a transfer device () that can display an image displayed on the displays (to) of the first operation console () on the displays (to) of the operation command console (), and a switching device () that switches an image on the displays (to) of the operation command console () to the image on the displays (to) of the first operation console transferred by the transfer device () are provided. With this configuration, it is possible to improve communications between the supervisor and the operation in operation of the nuclear power plant.

Operation monitoring apparatus of nuclear power plant

An auxiliary feedwater valve control apparatus of a steam generator that operates an auxiliary feedwater valve in an auxiliary feed water system provided as a protective system of a main feed water system that feeds secondary cooling water to a steam generator, includes a water-level detection means that detects a water level of secondary cooling water in the steam generator, a water-level-deviation calculation means that calculates a deviation between a preset target water level and a water level detected by the water-level detection means, a valve-operation setting means that sets an aperture of the auxiliary feedwater valve corresponding to a deviation of the water level, and a valve drive means that outputs a signal for driving the auxiliary feedwater valve corresponding to setting by the valve-operation setting means.
