High-availability design monitoring method for nuclear power unit

Abstract

The invention provides a high-availability design monitoring method for a nuclear power unit. Another technical scheme of the invention is to provide a nuclear power unit availability design monitoring device. The high-availability design monitoring method for the nuclear power unit has the following advantages: quantitative prediction and design monitoring of the operation availability and the equivalent forced outage rate of the nuclear power unit in the design stage are achieved; if the operation availability or the equivalent forced outage rate of the nuclear power unit cannot reach an excellent value, the improvement design of materials, structures and subsystems is carried out on the first three parts with relatively long forced shutdown hours of the nuclear power unit host and the subsystems, and mature products are adopted, so that the improvement of the availability of the nuclear power unit is realized, and the technical effect of improving the availability of the nuclear power unit through design monitoring is achieved.

Description

technical field [0001] The invention relates to a high-availability design monitoring method for nuclear power units, which is applied to the quantitative prediction and improvement of the availability of nuclear power units at the design stage, and belongs to the technical field of nuclear power units. Background technique [0002] Nuclear power units are composed of reactors and cooling systems, nuclear power auxiliary systems and safety facilities, nuclear power control and protection systems, steam turbines and auxiliary systems, generators and electrical systems. The indicators for evaluating the availability of nuclear power units are operational availability AO and equivalent forced shutdown The luck rate EFOR. In the use stage of nuclear power units, the power industry standard "Evaluation Procedures for Power Generation Equipment Operational Reliability" (DL / T793) can be used to determine the operational availability AO and equivalent forced shutdown of nuclear powe...

AI Technical Summary

Problems solved by technology

[0004] Since the composition of nuclear power units is different from that of thermal power units, the existing EFOR design monitoring methods and prediction methods for thermal power units cannot be applied to the design monitoring of the availability 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 availability
