Problems solved by technology
Because the curved wall, curved roof and factory building are consolidated together, the structure does not consider the vibration effect and fuel fire caused by the impact of the aircraft, which may easily cause damage or functional failure of the internal equipment of the factory building.

Embodiment Construction
[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described in the present invention are only for explaining the present invention, not for limiting the present invention.
[0028] According to the requirements for the integrity and cooling of reactors and spent fuel in the acceptance criteria in the regulations and guidelines, the reactor building, spent fuel storage building, electrical instrument control building (including the main control room where the operator handles the accident and the important instrument and control cabinets), special safety workshops for cooling functions and their functions (power supply, water intake) to support workshop structures for design protection.
[0029] Figure 1A , Figure 1B , Figure 1C It is a schematic diagram of several specific implementations of an overall protection scheme for a nuclear power pla...

The invention relates to a protection method and system for a nuclear power plant against the impact of a large commercial aircraft. The method sets up anti-collision structures for the reactor building, the spent fuel storage building, and the electrical instrument control building for protection. The safety plant and its function support plant structures are fully physically isolated from the impact-resistant structure, and protective structures are provided for possible openings or holes on the impact-resistant structure. The present invention realizes the comprehensive protection against the four effects (i.e. overall stability, partial penetration effect, vibration effect and fire effect) produced by the collision of large aircraft, and considers the balance of economy and the feasibility of engineering, and has great advantages. Good application prospects.
Description
technical field [0001] The invention belongs to the external event protection design technology of a nuclear power plant, in particular to a protection method and system for a nuclear power plant against the impact of a commercial large aircraft. Background technique [0002] After the September 11 incident in the United States, international attention was paid to the possibility of large commercial aircraft attacking key national facilities, including nuclear power plants. Various countries also have relevant requirements for applicants for new nuclear power plants, including the requirements of the US Federal Regulations 10CFR50 and the Western European Nuclear Regulatory Association WENRA. The domestic nuclear safety regulation HAF102 also clearly requires that the design of nuclear power plants consider the possibility of malicious attacks by large commercial aircraft, and through evaluation to prove that the design can maintain the cooling of the reactor core or the int...
