Moreover, the influence of the collapse can be reflected in the calculation of the simulated plant data of the plant 1 . As a result, it is possible to perform simulated operation of the plant 1 in consideration of a collapse occurring in the plant 1 and a relatively large-scale equipment failure, so that the skill level of the operation trainee can be improved. Therefore, according to the embodiment, disaster drills can be conducted from a wide perspective including inside and outside the plant 1 while taking into consideration the impact of the collapse of the plant 1 and buildings or topography in the surrounding area of the plant 1 .

In addition, the collapse simulation unit 52C identifies those devices included in the plant 1 that cannot operate normally due to the collapse of the building or terrain in the plant 1, and the operation training simulator 40 identifies the collapse simulation unit 52C. Simulated plant data is calculated based on the information of the device that cannot operate normally simulated in . With this configuration, it is possible to conduct operation training for the plant 1 assuming a large-scale equipment failure in which a building in the plant 1 collapses and a plurality of equipment cannot operate normally at the same time.

In addition, the disaster prevention training system 30 simulates how diffusion substances (radioactive substances) contained in the plant 1 diffuse into the plant 1 and surrounding areas based on simulated plant data in the disaster prevention training scenario S and the operation training simulator 40. A diffusion simulator 52E is further provided. With this configuration, by diffusing the radioactive materials contained in the plant 1, it is possible to conduct disaster prevention drills in consideration of the impact on the movement of trainees in the plant 1, evacuation, and the evacuation of personnel from the surrounding area.

In addition, the disaster prevention training system 30 further includes a weather condition setting unit 52D that sets the weather conditions of the plant 1 and the surrounding area based on the disaster prevention training scenario S, and the diffusion simulation unit 52E is set by the weather condition setting unit 52D. Simulates the diffusion of diffusive substances (radioactive substances) based on the weather conditions. With this configuration, it is possible to more accurately simulate the diffusion of diffusing substances (radioactive substances) in consideration of weather conditions.

The disaster prevention training system 30 also includes an input display terminal 54 (input device) through which information is input by a response trainee who is different from the operation trainee who operates the simulated operation terminal 44 during the disaster drill based on the disaster drill scenario S. further provide. With this configuration, a response trainee who is different from the operation trainee of the plant 1, such as a trainee in the countermeasures headquarters set up at the power company head office and a trainee in charge of evacuation guidance, can also receive various information through the input display terminal 54. can be entered. Therefore, it is possible to execute or simulate actions that the response trainee should take, and to easily record the details of the actions taken. As a result, a response trainee who performs response training separate from operation training can perform more appropriate training inside and outside the plant 1 . In addition, the content of the training can be easily confirmed later.

In addition, during the implementation of disaster prevention training based on the disaster prevention training scenario S, the disaster prevention training system 30 includes information on the collapse of the building or terrain simulated by the collapse simulation unit 52C, and the simulated plant data calculated by the operation training simulator 40. , and a storage unit 52A for storing a history of information input by the input display terminal 54. FIG. With this configuration, it is possible to collectively manage information related to the collapse of buildings or landforms, simulated plant data, and information input by response trainees who are different from plant 1 operation trainees during disaster drills. Thereby, it becomes possible to appropriately evaluate whether or not the training was properly performed after the training was completed.

Further, the input display terminal 54 receives information for changing a part of the disaster prevention training scenario S by the administrator who manages the disaster prevention training during the execution of the disaster prevention training. With this configuration, the administrator can change some of the multiple malfunctions MF1 to MF4 during the disaster drill, thereby increasing the flexibility of the disaster drill. Therefore, it becomes possible to implement more advanced disaster prevention drills.

Also, the plant 1 is a nuclear power plant. With this configuration, it is possible to appropriately train related trainees inside and outside the nuclear power plant.

In this embodiment, the disaster prevention training system 30 has two simulators, the operation training simulator 40 and the disaster prevention training simulator 50, but one simulator functions as the operation training simulator 40 and the disaster prevention training simulator 50. may be realized. That is, the disaster prevention training system 30 may have one simulator having the functions of the operation training simulator 40 (driving simulator) and the functions of the disaster prevention training simulator 50 . Moreover, the disaster prevention training simulator 50 may realize each function in a plurality of simulators.
