Discussion on the Application Prospect of Airborne Geophysical Prospecting in Site Selection and Construction of Nuclear Waste Disposal Sites

Abstract

In recent years, the international climate problem has become increasingly prominent, mankind is facing an unprecedented environmental crisis, and the demand for clean energy such as nuclear energy has become increasingly prominent, especially China's serious dependence on energy. The utilization of nuclear energy is a complex systematic project, in which the disposal of nuclear waste is related to the development and utilization of nuclear energy, and the site selection and construction of disposal sites is the key to restricting the development of nuclear energy. In order to realize the rapid site selection and construction of nuclear waste disposal sites, this paper relying on the application of airborne geophysical exploration in key projects in china, analyzes the methods of airborne gamma spectroscopy, airborne magnetism, airborne electromagnetism and other methods to solve the geological problems of nuclear waste disposal sites ability: Aerial gamma spectroscopy can provide potassium, uranium and thorium content, which can quickly determine the distribution range of granite bodies; aeromagnetic measurement can provide magnetic field and three-dimensional magnetic spatial distribution, and can analyze regional fractures and deep rock development characteristics; aerial electromagnetic measurement can provide plane time constant and three-dimensional resistivity parameters, which can be used to analyze the deep development characteristics of rock mass and faults. Comprehensive aerial geophysical exploration can analyze the characteristics of deep geological bodies from the aspects of radioactivity, magnetism and electrical properties, and can provide a three-dimensional geophysical basis for the rapid site selection and construction of nuclear waste disposal sites, application prospects.
