Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] The embodiment of this application provides a method for evaluating the reliability of the nuclear power conventional island water supply system, such as figure 1 shown, including the following steps:

[0055] S101. Obtain the operating parameter set of the system in the current state;

[0056] In this step, a plurality of measuring points may be preset in the system, and each measuring point obtains an operating parameter of the system, and the operating parameters obtained by each measuring point may be different in different states of the system. In the current state of the system, the set of operating parameters obtained by all measuring points is taken as the operating parameter group of the system in the current state. I...

Abstract

The invention discloses a nuclear power conventional island water supply system reliability evaluation method and device, and relates to the technical field of reliability evaluation. The method comprises the following steps: obtaining an operation parameter group of a system in a current state; determining a faulty element corresponding to the operating parameter group according to the operatingparameter group; correcting the reliability parameter of the faulty element; and calculating the reliability of the system according to the reliability parameters of each element in the system. According to the nuclear power conventional island water supply system reliability evaluation method and device provided by the invention, accurate reliability evaluation can be carried out according to thecharacteristics of multiple elements and multiple fault states of the nuclear power conventional island water supply system.

Description

technical field [0001] The invention relates to the technical field of reliability evaluation, in particular to a method for evaluating the reliability of a nuclear power conventional island water supply system. Background technique [0002] As one of the important systems of the conventional island of the nuclear power plant, the water supply system undertakes the important task of delivering the secondary circuit water source to the steam generator of the nuclear island and maintaining the water level of the steam generator. Due to the high risk of nuclear island operation, the reliability of the nuclear power conventional island water supply system is extremely high, so it is of great significance to accurately evaluate the reliability of the nuclear power conventional island water supply system. [0003] In related technologies, methods such as fault tree method, Monte Carlo method, GO method, and Markov method can be used to evaluate system reliability. [0004] In the...
