Problems solved by technology

[0003] However, the existing PSA model is relatively professional and not suitable for non-professionals. Moreover, the model cannot reflect the real-time status of the power plant and cannot directly evaluate the risks of nuclear power plants in real time. Therefore, the existing PSA model must be modified to meet the requirements of nuclear power plants. The risk assessment model of the actual situation of the equipment can accurately obtain real-time assessment results

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] In the process of implementing the embodiments of the present invention, it is mainly to set a risk real-time evaluation model. The existing PSA model is only a benchmark model, which cannot reflect the real-time status of the power plant, so the real-time risk evaluation of the nuclear power plant cannot be given, so reasonable risk The real-time evaluation model stores the relationship between power plant equipment and its failure modes and failure paramete...

Abstract

The invention discloses a method for evaluating risk of nuclear power station, comprising the following steps: receiving the maintenance device state value transmitted by the user device, wherein the maintenance device is a power plant device to be regularly maintained by the user or regularly tested or a power plant device for evaluating risk value when something is wrong with the device, computing the risk evaluation value of the nuclear power station based on the risk real-time evaluation model according to the maintenance device state value, and transmitting the computed risk evaluation value to the user device where the user is. The invention further discloses a device for evaluating risk in real time. The embodiment of the invention is convenient for the operator to realize the riskcondition of the nuclear power station in real time.

Description

technical field [0001] The invention relates to a method and a device for nuclear safety management of a nuclear power plant, in particular to a method and a device for risk assessment of a nuclear power plant. Background technique [0002] For nuclear power plants, equipment failures and personnel errors are the main reasons that affect the safety and stable power generation of nuclear power plants. Therefore, a method or process for effectively managing these equipment and personnel operations is very important. The risk-guided safety management concept is the method and process that meet this requirement, and the probabilistic safety assessment (PSA) is an important part of it. information to effectively manage plant equipment and personnel operations. [0003] However, the existing PSA model is relatively professional and not suitable for non-professionals. Moreover, the model cannot reflect the real-time status of the power plant and cannot directly evaluate the risks...
