High-reliability design monitoring system and method for nuclear power unit

Abstract

The invention provides a high-reliability design monitoring system and method for a nuclear power unit. The high-reliability design monitoring system comprises a nuclear power unit reliability computing server, wherein the computing server is used for operating reliability design monitoring and improvement software of the nuclear power unit, the computing server is in communication connection witha database server used for storing basic data of the operation reliability of the nuclear power unit and a webpage server; and the webpage server is in communication connection with a user side browser. The high-reliability design monitoring system improves the reliability of the nuclear power unit by improving and designing materials, structures and subsystems of the first three parts with relatively long non-planned outage hours of the nuclear power unit host and the subsystems, adopting mature products, optimizing refueling overhaul days of the nuclear power unit and the like, achieves thetechnical effect of improving the reliability of the nuclear power unit through reliability design monitoring, and achieves quantitative prediction and design monitoring of the reliability of the nuclear power unit in the design stage.

Description

technical field [0001] The invention relates to a high-reliability design monitoring system and method for nuclear power units, which are applied to the quantitative prediction and improvement of the reliability of nuclear power units in the design stage, and belong to the technical field of nuclear power unit design. Background technique [0002] Such as figure 2 As shown, the nuclear power unit system is mainly composed of reactor and cooling system, nuclear power auxiliary system and safety facilities, nuclear power control and protection system, steam turbine and auxiliary system, generator and electrical system. figure 2 The arrows in represent the interaction relationship and the input and output of the nuclear power unit. The index to evaluate the reliability of the nuclear power unit is the equivalent availability factor EAF. In the use stage of nuclear power units, the power industry standard "Reliability Evaluation Procedures for Power Generation Equipment" (DL / T7...

AI Technical Summary

Problems solved by technology

[0004] Since the composition of nuclear power units is different from that of thermal power units, the planned maintenance of nuclear power units is mainly refueling and overhaul. The existing monitoring methods for availability design and reliability prediction of thermal power units cannot be applied to the reliability design monitoring of nuclear power units.

In the design stage of nuclear power units, there are no suitable design monitoring methods and software systems available for quantitative prediction, improvement and design monitoring of nuclear power unit reliability
