Problems solved by technology

Nuclear power plants have high safety fortification requirements. Affected by typhoons, nuclear power plants usually take measures in advance to reduce the risk of safe operation caused by typhoons, but damage and losses still occur to varying degrees
The typhoon mainly affects the nuclear power plant through three aspects: 1) strong wind and wind pressure cause damage or damage to the site items of the nuclear power plant; Heavy rainfall and strong winds and waves caused flooding of the nuclear power plant site, affecting the normal operation of items at the site of the nuclear power plant
[0003] At present, in the domestic existing technology, there is no clear evaluation method for the evaluation of the anti-typhoon capability of nuclear power plants

Abstract

The invention discloses a nuclear power plant anti-typhoon influence assessment method and system, and the method comprises the steps: determining a typhoon level corresponding to a nuclear power plant site item wind resistance assessment reference according to a typhoon level corresponding to a nuclear power plant site item original wind load design reference wind speed and a nuclear power plant site item anti-typhoon target level; determining a wind pressure influence scene of the nuclear power plant influenced by a typhoon according to the typhoon level corresponding to the wind resistance evaluation benchmark of the site item of the nuclear power plant; according to the plant site item type of the nuclear power plant, determining a flying object influence scene; determining a flooding influence scene according to storm surge, rainfall and storm wave data of the nuclear power plant site; and respectively carrying out prevention and resistance capability analysis on the nuclear power plant site item in the three scenes, and judging the influence condition of the typhoon on the nuclear power plant site item in each scene. The method has universality and can provide reference for wind resistance improvement of the nuclear power plant so as to reduce the influence of typhoon on the nuclear power plant and improve the safety and usability of the nuclear power plant.

Description

technical field [0001] The invention relates to the technical field, in particular to a method and system for evaluating the impact of a nuclear power plant against typhoons. Background technique [0002] Most of my country's nuclear power plants are built on the southeast coast. In recent years, strong typhoons have landed near nuclear power plants. Nuclear power plants have high requirements for safety and fortification. Affected by typhoons, nuclear power plants usually take measures in advance to reduce the risk of safe operation caused by typhoons, but there are still various degrees of damage and loss. Typhoons mainly affect NPPs in three ways: 1) Strong wind pressure causes damage or damage to items on the site of the NPP; 2) The projectiles caused by the wind impact the items on the NPP site and cause damage or damage; 3) Accompanied by typhoons Heavy rainfall and strong wind and waves caused flooding in the plant area of ​​the nuclear power plant, affecting the nor...
