2. Description of the Related Art Conventionally, for example, when collecting detailed data of a fuel assembly from core performance calculation results,
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 with the keyboard to request output. At that time, the coordinates of the target fuel assembly are usually selected at the most thermally strict part in the core, and in order to search for that position, other thermal limit values are displayed or printed. It was necessary to memorize the thermally severest coordinates on the core, demanding functionality. Further, there are several kinds of values that serve as an index of the thermal limit value, and when collecting data for each, it was necessary to search several kinds of coordinates as well.

Therefore, since the coordinate input information is not properly gathered in one place and the coordinate input screen is separated from the coordinate input information, the operability is poor and there is a case where the coordinate input information is erroneously input. Further, normally, the function required by inputting the coordinates is to output the detailed data of the fuel assembly, LPRM and control rod at the specified coordinates, or to output the data of all fuel assemblies around the designated LPRM and control rod.

The operation of the apparatus having the above structure will be described below.
First, the CRT 9 displays a menu screen in an initial state as shown in FIG. The displayed contents are divided 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 calculation device 6 calculates the latest data stored in the core performance evaluation summary data file 10 calculated in advance by the core performance calculation program based on the plant data. From the core performance evaluation summary data, the fuel rod power density (LHGR), the critical power ratio (CPR), and the fuel average power density (APLHG), which are thermal indicators for core operation management,
R) and other coordinates of the maximum value in the core are calculated. From the calculation result and the core map display fixed information data, the coordinate input screen editing device 7 positions the color-changing place on the core map and synthesizes the coordinate input screen. The combined information is displayed on the CRT via the CRT display / input control device 5, for example, in the format shown in FIG. Operators typically want data for the most thermally demanding locations,
In FIG. 2, of the fuel assemblies, one of the three thermal conditions that is severe is selected for each condition, and the position of the selected fuel assembly is displayed in a color different from the other parts. There is.

The operator selects any one of the displayed positions changed in color by touch operation, mouse pick operation, light pen operation, etc., and the detailed data of the fuel assembly at the selected position is displayed by the typewriter. Is output to an output device such as. The process flow is as follows. First, CR
On the T display / input control device 5, touch, mouse pick,
Alternatively, the position on the CRT operated by the light pen is captured, 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 apparatus 1A, and in the core performance evaluation detailed data editing apparatus 1A, from the latest core performance evaluation detailed data and the sent fuel assembly coordinates, Import and edit the data of the corresponding fuel assembly,
Output to the core performance evaluation detailed data output device 1B.

The same is true when the items of control rod data and LPRM data are selected from the initial menu screen.
Coordinate input screen (core map screen) displayed on CRT
Is as shown in Figure 2.

Conventionally, three types (for example, LHGR, CPR, AP
LHGR) thermal limit values are displayed on each screen to store the strictest coordinates in the core, or make a note of them, display the detailed data output menu screen, and store it. Or, the detailed data was collected by entering the coordinates that were noted in the keyboard. On the other hand, in this method, since the fuel assemblies in the most severe condition for each of the three thermal limit values are color-coded and displayed on the core map of the same screen, that portion is touched,
Detailed data of the selected fuel assembly is output only by performing the mouse pick operation or the light pen operation three times and selecting and designating.

Therefore, the target fuel assembly, control rod, LP
Fuel assembly, control rod, LP selected from RM selection
The operation until the output of the RM data is simplified, and erroneous input of the coordinates for specifying the fuel assembly, the control rod, and the LPRM is eliminated. Further, the coordinate color replacement data calculation device 6 is
As described above, fuel rod power density (LHGR), critical power ratio (CPR), fuel average power density (APLHGR)
Since the core coordinates of the fuel assemblies, control rods, LPRMs, etc. whose thermal limit values show the maximum in-core value are calculated, the above-mentioned thermal limit is always maintained regardless of the output state of the plant. The position coordinates of the fuel assemblies, control rods, LPRMs, etc. having the maximum limit value (the minimum value depending on the numerical value) can be displayed in different colors.

In the above embodiment, the coordinate color change data calculation device 6 calculates the in-core coordinates of the fuel assemblies, control rods, LPRMs, etc. where the thermal limit value shows the maximum in-core value. Instead of the value, for example, the coordinate area of the one included in a range from the highest to the% may be color-changed and displayed, or the coordinate area of the one that exceeds a certain limit value may be color-displayed.

<Second Embodiment> 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 items displayed by dividing the range up to 100% output into four, such as offline plan data comparison output 20% and offline plan data comparison output 50%. Further, the core performance evaluation summary data and the core performance evaluation detailed data in Example 1 were intended only for the calculation results of the latest core performance program, but in this example, in addition to the latest data, the core operation was performed by the offline computer. 20% and 50% when planning
The off-line planning data at the output level that is the starting point of the above is input to the process computer (not shown). In this state, for example, when the output of the plant reaches 20% and the item “offline plan data output 20%” on the initial menu screen 41 is selected, the coordinate color replacement data calculation device 6 causes the core performance evaluation. Of the summary data, the output of the offline plan data of 20% and the latest summary data of the core performance evaluation are three types (for example, LHG
For each thermal limit of R, CPR, APLHGR, calculate the coordinates where it is in the most severe state in the core. Thereafter, as in 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 through the CRT display / input control device 5 while being classified into three types to six types. For example, if the offline plan and the current core state are the same, the generation coordinates of the maximum core value of the three types of thermal limit values also match, and there are three types of color coding, but the offline plan and the current core state are completely different. If they are different, there are also 6 types of color classification. 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 by selecting and designating the position of any of the three to six colored fuel assemblies by touch operation, mouse pick operation, or light pen operation. The difference between the offline plan detailed data and the current detailed data of the fuel assembly at the different position is calculated and edited and output to an output device such as a typewriter.
In this embodiment, the fuel assembly having the coordinates (a, b) is selected, and the offline plan detailed data and the current detailed data are graphically displayed (display screen 33), and the difference between the two is analogized. While being displayed, the offline plan detailed data, the current detailed data, and the difference between the two are printed out by the typewriter.

The flow of processing from the designation of the position on the display screen to the data output is as follows. First, the CRT display / input control device 5 captures the selected and designated position on the CRT, and the coordinate calculation device 8 converts the position information on the CRT into fuel assembly coordinates. Furthermore, the offline performance detailed data and the current detailed data at the time when the output of the corresponding fuel assembly is 20% are fetched by the core performance evaluation detailed data editing device, and the difference calculation etc. is carried out to perform the core performance. It is output to the evaluation detailed data output device.

Conventionally, the comparison between the offline plan data created at the time of core operation planning and the current core operating state was obtained by searching the coordinates of the current thermally severest fuel assembly and inputting the coordinates. For example, the result and the offline plan data printed out in advance were manually calculated to find the difference. On the other hand, in the present embodiment, the labor of coordinate search, manual calculation, etc. is greatly reduced, and the occurrence of input errors, calculation errors, etc. is reduced.

In the process of starting the plant, the offline plan and the current state are always compared, and if they do not match, it is necessary to collect prompt and accurate data in order to investigate the cause. In the present embodiment, the position coordinates of the fuel assembly, control rod, LPRM, etc., which are to be compared and have severe thermal conditions, are quickly found, and at the same time the coordinates are found, the fuel assembly, control rod at the coordinate position, It is possible to output detailed data such as LPRM, and it is possible to immediately start investigating the cause of the disagreement between the two.

[0026]

When collecting detailed data of fuel assemblies, control rods, LPRMs, etc. in order to grasp and analyze the core condition, first, the fuel assemblies, control rods, LPs from which data should be collected are collected.
It is necessary to search for coordinates such as RM. According to the present invention, it is possible to search for coordinates of a fuel assembly or the like for which data is to be collected, input coordinates, and request to collect data at one time on a single menu screen, thus reducing human error such as coordinate input error. And, it became possible to collect data quickly. 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 relating to plant operation will occur, and the cause will be investigated. Therefore, it is necessary to collect and evaluate data quickly and accurately. The present invention is particularly effective under such a situation.
