Experiment research on electromagnetic pulse effects of typical nuclear security system

Abstract

High-altitude electromagnetic pulse(HEMP) is a kind of transient electromagnetic wave which can be coupled into various electronic and electrical equipments through field lines or holes. To ensure that the security system of key departments can work normally under the electromagnetic pulse environment, it is necessary to carry out the electromagnetic pulse effect test against the security system, and analyze the weak link and survival ability of this kind of system under the electromagnetic pulse environment. According to the topology of nuclear security system, the electromagnetic pulse radiation test and pulse current injection test platform are set up, and the threshold and effect phenomena of the key components of the nuclear security system are obtained through the test. Furthermore, the failure mechanism of key components is analyzed based on the circuit principle of each component, and the weak link of typical nuclear security system is summarized, which provide data support for the protection and reinforcement design of the follow-up security system.
