Embodiment Construction

[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] In a preferred embodiment, refer to figure 1 , this embodiment provides a set of algorithms that can quickly quantify the risk level. By setting the equipment unavailable, the core damage frequency (Core Damage Frequency, CDF) or early large release frequency (Large early release frequency, LERF) is requantified with the cut set database, and the important Combinations of initiating events, accident sequences, and equipment failures, so as to provide guidance for various production activities of nuclear power plants, such as the scheduling of work plans by planning engineers, and on-site work by operators, so as to achieve better risk management and control, and improve nuclear power plants. crew safety. Specif...

Abstract

The invention relates to a nuclear power plant fault level calculation method based on probabilistic safety analysis and a computer. The method comprises the following steps: S1, establishing a minimum cut set database, exporting data files of the minimum cut set database in batches according to an accident sequence, and storing the data files in a table and database division manner; s2, performing quantification processing on the minimum cut set in the minimum cut set database; and S3, calculating risk information by using the quantified minimum cut set database. According to the algorithm for rapidly quantifying the risk level, the risk information of the nuclear power plant can be rapidly calculated, so that guidance is provided for various production activities of the nuclear power plant, better risk management and control are achieved, and the safety of a nuclear power unit is improved.

Description

technical field [0001] The invention relates to the field of safety management of nuclear power plants, and more specifically relates to a method for calculating fault levels of nuclear power plants based on probabilistic safety analysis and a computer. Background technique [0002] At present, the management of multiple equipment failures in nuclear power plants is relatively simple mainly through technical specifications, and the risks introduced by multiple equipment failures cannot be controlled. Improving the level of nuclear safety management has an inherent demand driving force for configuration risk management. The National Nuclear Safety Administration has released the "Technical Policy for Risk Management of Nuclear Power Plant Configuration (Draft for Comment)", which requires the use of risk monitor tools to evaluate the risk level of power plant configuration, and a set of rapid quantitative calculation of nuclear power plant risk The horizontal algorithm can me...
