DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for selecting an instruction for inputting a reactor core performance calculation which is an interface of a man-machine for core performance calculation which is one of the functions of a process computer of a nuclear power plant.

2. Description of the Related Art Conventionally, for example, when obtaining detailed data of a fuel assembly from a core performance calculation result,
The menu screen of the detailed data collection function was displayed, and the coordinates of the target fuel assembly were input to the coordinate input position on the menu screen using the keyboard, and an output request was made. At that time, the coordinates of the target fuel assembly are usually selected at the most thermally severe point in the core, and to find that position, the function of displaying other thermal limit values or printing is used. In order to request a function, it was necessary to memorize the coordinates on the thermally most severe core. In addition, there are several types of values that serve as indices of the thermal limit value, and when collecting data for each of them, several types of coordinates must be similarly searched. FIG. 4 shows an example of a conventional procedure for determining input coordinates and a procedure for requesting data output. The detailed data of the fuel assembly includes a longitudinal power distribution of each fuel assembly, a critical power ratio (CPR), a linear power density (LHGR), a burnup distribution,
There are flow distribution, void distribution and the like.

A technique for displaying the LPRM and the control rods in different colors is described. However, in this method, since the numerical range for grouping is fixed, it is not possible to change and display the parts having the strictest conditions in accordance with various output stages of the plant.

The operation of the apparatus having the above configuration will be described below.
First, an initial menu screen as shown in FIG. 2 is displayed on the CRT 9. The display contents are classified into fuel assembly data, control rod data, and LPRM data. For example, when the operator selects the fuel assembly data, the coordinate color change data calculating device 6 updates the latest coordinate data calculated in advance by the core performance calculation program based on the plant data and stored in the core performance evaluation summary data file 10. From the core performance evaluation summary data, the fuel rod power density (LHGR), critical power ratio (CPR), and fuel average linear power density (APLHG)
The coordinates of the maximum value in the core such as R) are calculated. From the calculation result and the core map display fixed information data, the coordinate input screen editing device 7 positions a color change place on the core map and synthesizes a coordinate input screen. The synthesized information is displayed on the CRT via the CRT display / input control device 5, for example, in the format shown in FIG. Operators typically seek data for the most thermally demanding locations,
In FIG. 2, one of the three fuel assemblies having severe thermal conditions is selected for each condition, and the position of the selected fuel assembly is displayed in a different color from the other parts. I have.

The operator selects one of the positions displayed by changing the color by a touch operation, a mouse pick operation, a light pen operation, or the like, and the detailed data of the fuel assembly at the selected position is displayed on the typewriter. And the like. The flow of the processing is as follows. First, CR
In the T display / input control device 5, touch, mouse pick,
Alternatively, the position on the CRT operated by the light pen is taken in, and the coordinate calculation device 8 converts the position information on the CRT into fuel assembly coordinates. Further, the fuel assembly coordinates are sent to the core performance evaluation detailed data editing device 1A, and the core performance evaluation detailed data editing device 1A obtains the latest core performance evaluation detailed data and the sent fuel assembly coordinates from the latest core performance evaluation detailed data. Import and edit the relevant fuel assembly data,
Output to the core performance evaluation detailed data output device 1B.

The same applies to the case where the control rod data and LPRM data items are selected from the initial menu screen.
Coordinate input screen (core map screen) displayed on CRT
Is as shown in FIG.

Conventionally, three types (eg, LHGR, CPR, AP
(LHGR) is output, and the most severe coordinates in the core are stored or written down, and a menu screen for detailed data output is displayed and stored. Or input the coordinates that were memoted with the keyboard to collect detailed data. On the other hand, in this method, the fuel assembly in the severest condition for each of the three thermal limit values is displayed in a different color on the core map on the same screen.
By simply performing a mouse pick operation or a light pen operation three times to select and specify, detailed data of the selected fuel assembly is output.

Therefore, the target fuel assembly, control rod, LP

The position coordinates of the fuel assembly, control rod, LPRM, or the like having the maximum limit value (or the lowest value depending on the numerical value) can be displayed in different colors.

In the above embodiment, the coordinate color change data calculating device 6 calculates the in-core coordinates of the fuel assembly, the control rod, the LPRM, etc., in which the thermal limit indicates the maximum value in the core. Instead of a value, for example, the coordinate area of a coordinate area included in a certain percentage from the higher one may be displayed in a different color, or the coordinate area of a coordinate area exceeding a certain limit value may be displayed in a different color.

<Embodiment 2> Next, a second embodiment of the present invention will be described with reference to FIG. First, an initial menu screen 31 is displayed on the CRT 9. The display contents are displayed by dividing the range up to 100% output into four items, such as an off-line plan data comparison output of 20% and an off-line plan data comparison output of 50%. In addition, the core performance evaluation summary data and the detailed core performance evaluation data in the first embodiment are only for the calculation results of the latest core performance program. In the present embodiment, in addition to the latest data, the core operation using an offline computer is performed. 20% and 50% when planning
Offline plan data at an output level serving as a starting point is input to a process computer (not shown). In this state, for example, when the output of the plant reaches 20% and the item of “offline planning data output 20%” on the initial menu screen 41 is selected, the coordinate color change data calculation device 6 performs the core performance evaluation. Three types (for example, LHG) of the 20% output of the offline plan data of the summary data and the latest core performance evaluation summary data
For each of the thermal limits R, CPR, APLHGR), calculate the coordinates at which it is the most severe in the core. Thereafter, similarly to the first embodiment, the coordinate input screen editing device 7,
The colors of the fuel assemblies on the core map are displayed on the CRT 9 via the CRT display / input control device 5 in three to six types. For example, if the off-line plan and the current core state are the same, the generation coordinates of the core maximum value of the three types of thermal limit values also match, and three colors are used. If different, there are also six types of color coding. The display screen 32 of FIG.
An example is shown in which individual positions are displayed in four different colors. The operator selects and designates any one of the three to six colored fuel assemblies by a touch operation, a mouse pick operation, or a light pen operation. The difference between the off-line plan detailed data and the current detailed data of the fuel assembly at the position where it was set is calculated and edited and output to an output device such as a typewriter.
In the present embodiment, the fuel assembly at the coordinates (a, b) is selected, and the detailed data of the off-line plan and the current detailed data are displayed in a graph (display screen 33), and the difference between them is displayed in an analog manner. At the same time, the offline plan detailed data, the current detailed data, and the difference between the two are printed out on a typewriter.

The flow of processing from designation of a position on the display screen to data output is as follows. First, the CRT display / input control device 5 takes in the position on the CRT selected and designated, and the coordinate calculation device 8 converts the position information on the CRT into fuel assembly coordinates. Further, the detailed data of the offline plan and the current detailed data at the time of 20% output of the corresponding fuel assembly are taken in based on the coordinates of the fuel assembly by the core performance evaluation detailed data editing device, and the difference calculation and the like are performed to perform the core performance. It is output to the evaluation detailed data output device.

Conventionally, the comparison between the off-line planning data created during the core operation planning and the current core operation state is obtained by searching for the coordinates of the currently thermally severest fuel assembly and inputting the coordinates. The difference between the result and the off-line plan data previously printed out was calculated manually. On the other hand, in the present embodiment, the trouble of coordinate search, manual calculation, and the like is greatly reduced, and the occurrence of input errors, calculation errors, and the like is reduced.

In the process of starting the plant, comparison between the off-line plan and the current state is always performed. If the two do not match, it is necessary to collect quick and accurate data to investigate the cause. In the present embodiment, the position coordinates of the fuel assemblies, control rods, LPRMs, etc., for which the thermal conditions to be compared are severe, are quickly found, and the fuel assemblies, control rods, It is possible to output detailed data such as LPRM, and it is possible to immediately start the investigation of the cause of the inconsistency.

[0026]

When collecting detailed data of fuel assemblies, control rods, LPRMs, etc. in order to grasp and analyze the state of the core, first, the fuel assemblies, control rods, and LPs from which data should be collected.
Coordinates such as RM must be searched. According to the present invention, it is possible to search for coordinates of a fuel assembly or the like to be data-collected, input coordinates, and request data collection at once on a single menu screen, thereby reducing human errors such as coordinate input errors. In addition, quick data collection has become possible. In particular, as shown in Example 2, if the core performance evaluation data planned offline and the current core performance evaluation data do not match, a problem related to plant operation may occur. Therefore, quick and accurate data collection and evaluation is required. The present invention is particularly effective under such circumstances.
