Study of nuclear power plants building subjected to aircraft impacts

Abstract

According to the requirements of nuclear safety regulations, human-induced events such as aircraft impacts must be considered in the design of nuclear power plants (NPPs). The aircraft include three types, military aircraft crashes, ordinary aircraft crashes, and large commercial aircraft impacts. According to the regulations and standards of the International Atomic Energy Agency (IAEA) and China, for the classification of human-induced events, the first two belong to human-induced design basis events, and the latter belongs to human-induced beyond design basis events. As military aircraft belong to military facilities, this paper will not discuss it. Instead, it focuses on the impacts of ordinary aircraft and large commercial aircraft. In this paper, the numerical simulation of the large commercial aircraft impacts is carried out based on the force time-history analysis method. This paper also conducted a design basis aircraft crashes investigation. Resultantly, this study provides a reference and guidance for the design of NPPs buildings subjected to ordinary aircraft and large commercial aircraft. By investigating the laws and standards at home and abroad, this paper puts forward suggestions on the design of NPPs against aircraft crashes and suggestions for the formulation of regulatory policies for large commercial aircraft impacts.
