Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] see figure 1 , the present invention provides a technical solution: a calculation method for evaluating the frequency of aircraft crashes to nuclear power plant sites. According to the relevant requirements in HAD101 / 04-1989, when selecting a site for a new nuclear power plant, airports within 10 kilometers from the nuclear power plant need to be considered And the risk caused by the route within 4 km to the nuclear power plant, and gives 10-7 per react...

The invention relates to the technical field of safety evaluation, and particularly discloses a calculation method for evaluating the frequency of aircraft crash to a nuclear power plant site, which comprises the following steps of: 1, enabling a nuclear power plant site range to be equivalent to a rectangular facility capable of minimizing the envelope of the nuclear power plant site range, and calculating the effective area of the rectangular facility; 2, determining related information of all airports near the nuclear power plant by combining specific information of the nuclear power plant, and calculating the frequency of aircraft crash to the site of the nuclear power plant; the calculation method can evaluate the frequency of crashing airplanes in the airport take-off and landing process and airplanes flying on the airline to the nuclear power plant site range, solves the technical difficulty of nuclear power plant aircraft impact probability safety evaluation PSA, lays a foundation for establishing nuclear power plant aircraft impact PSA, and has a great significance in promoting the safety technology and economic technology of the nuclear power plant PSA to be mature. And the method is of great significance in providing commercial competitiveness.
Description
technical field [0001] The invention relates to the technical field of safety evaluation, in particular to a calculation method for evaluating the frequency of aircraft crashing to a nuclear power plant site. Background technique [0002] At present, domestic and foreign assessments of the risk of aircraft crashing into nuclear power plants remain at the level of screening according to regulations and guidelines and deterministic aircraft crash design. There is no PSA (Probabilistic Safety Assessment of Nuclear Power Plant) method that can be used for external events of aircraft impact at home and abroad. Similar to the PSA method for external events such as earthquakes, flooding, and strong winds, the aircraft impact PSA method should also be divided into three parts: aircraft impact Hazard analysis, aircraft impact vulnerability analysis and aircraft impact power plant response analysis. [0003] One of the keys to establish a PSA for aircraft impact in a nuclear power pl...
