Description

Apparatus of analyzing multiple spurious operation}

The present invention relates to a multiple malfunction analysis device.

If a fire occurs at a nuclear power plant, damage to equipment and cables related to the safe shutdown of the nuclear power plant may occur. This damage can have a negative impact on the nuclear power plant's safe shutdown function. Therefore, taking this into consideration, it is necessary to analyze and identify in advance the potential for malfunction of a nuclear power plant due to a fire. To this end, in fire safety stop analysis, it is necessary to derive a list of safety stop devices that may have a negative impact on safety stop in the event of a fire, identify essential cables through circuit analysis, and identify the locations of safety stop devices and essential cables. Through this, the satisfaction level of fire protection requirements must be evaluated for each fire prevention area. In particular, fire safety shutdown analysts must perform detailed circuit analysis by applying cable failure modes (disconnection, high-temperature short circuit, ground fault, etc.) specified in NEI00-01 to derive cables that are essential for performing the functions of the safety shutdown device. However, since detailed circuit analysis is performed manually, the analysis time becomes very long, and the detailed circuit analysis results are also manually entered into the database system, which may reduce the efficiency, accuracy, and reliability of the analysis work.
