Specific features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. It is to be noted that the detailed description of known functions and constructions related to the present invention is omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

The nuclear power plant risk assessment analysis system and risk assessment method of the present invention will be described with reference to FIGS. 1 to 2.

FIG. 1 is an overall configuration diagram conceptually illustrating a nuclear power risk assessment analysis system according to an embodiment of the present invention, and includes a receiver 100 and an analyzer 200 as a whole.

The receiving unit 100 receives and stores in real time operating state data of major power plant power plants stored in the power plant watchdog.

More specifically, the power plant watch tube of a nuclear power plant stores reliable signals that can check the operation status of major power plants in its database in real time, and the operation status of a specific device through individual signals or a combination of multiple signals. You can figure out exactly. Therefore, the receiver 100 receives a variable representing an operating state of a device operating in the nuclear power plant by using the power plant monitoring system of the nuclear power plant and stores it in its own database. In order to increase the reliability of the signal, various kinds of information can be received, that is, not only the logical result value (during operation and stop) of the operation of the device, but also various output values (motor rotation speed, discharge flow rate, pressure, temperature). Etc.) to receive and store.

The reception system is a communication system using wired and wireless, and in particular, in wireless communication, a wi-fi, which is a broadband wireless communication network, may be used, but the present invention is not limited thereto. A system capable of receiving data stored in a plant alarm box is sufficient and does not limit its method.

The analysis unit 200 analyzes and removes an error generated during transmission using the information received from the receiving unit 100 and stores only information valid for risk assessment. The analysis unit 200 includes a noise analysis module 210, a noise removal module 220, and an information storage module 230.

The noise analysis module 210 analyzes whether or not noise due to a malfunction of the power plant monitoring system and other signals generated while information is received from the plant monitoring system. This is because, if there is an error due to disturbance during data transmission, the reliability may be degraded in risk assessment.

The noise removal module 220 removes the data analyzed as noise, that is, an error, from the noise analysis module 210. The noise removal module 220 is made of the same algorithm as the noise analysis module 210, and the data analyzed as noise in the noise analysis module 210 is immediately removed.

The information storage module 230 stores information that is recognized as valid data, that is, final information about the device to be used for risk assessment, in addition to the data removed by the noise analysis module 210 and the noise removal module 220.

2 is an overall flowchart of a method for automatically assessing nuclear risk using a data reception / analysis system of nuclear risk assessment according to an embodiment of the present invention.

In the nuclear plant automatic risk assessment method using the nuclear reactor risk evaluation data reception / analysis system including the receiver 100 and the analyzer 200, the receiver 100 stores the nuclear power plant stored in the plant monitoring system. Receive real-time operation state data of the main power plant (S10). The plant alarm clock receives the information stored therein because it stores a reliable signal in real time to check the operation status of major plant equipment.

The receiving unit 100 stores the received information from the power plant watch box to analyze whether the information is valid (S20). The analyzer 200 temporarily stores the received information in the receiver 100 itself in order to analyze whether the received information is valid.

The noise analysis module 210 analyzes whether the information stored in the receiver 100 is a noise (error) due to a malfunction of a signal generated during the reception of information from the power plant monitoring system and other power plant monitoring system and removes the noise. ) To remove the data analyzed as noise (S30). Through the algorithm that analyzes the error due to the disturbance when transmitting the data, the transmitted data is analyzed for noise and removes the remaining noise data, leaving only the final data for the device used for risk assessment. The noise of the transmitted data is analyzed and the data determined to be noise is immediately removed. In practice, this step is necessary for reliable risk assessment because data transmission and reception and malfunction of the device may transmit data different from the actual power generation device situation.

The information storage module 230 stores only valid information recognized through the analysis / removal step (S40). In fact, the reason for storing the data through the above process is to be used in the risk assessment of nuclear power plants, and only the valid information of the information received from the nuclear power plant sense clock is stored again.

The nuclear power risk is evaluated using the information stored in the information storage module 230 (S50). The nuclear risk assessment method is a conventional risk assessment method. In other words, quantitatively or qualitatively assess the risk of nuclear power plants, identify the operating state of power generation equipment and automatically drive it using a separate computer code.
