In this research work, a possible technical solution for the growing Civilian Unmanned Aerial Vehicles (UAVs) threat to nuclear facilities is presented. A conceptual system architecture for countering the civilian UAVs threat with detection modalities as well as major types of effectors and mitigation systems has been illustrated. With the investigation over R&D activities and literature for a robust technical solution, a combination of Radio Frequency (RF) emission cum sound event detection and jamming based Physical Protection System (PPS) has been proposed to counteract the UAVs threat as well as to account for real time alert and response. The system architecture also outlines the criteria for a response system involving both the destructive and non-destructive techniques according to the available tested means and technologies. The solution can be applied to upgrade the PPS of existing nuclear facilities and to design the PPS of nuclear facilities of newcomer countries like Bangladesh where the UAVs threat may not have been considered with other threat attributes. The paper will enable policy makers, regulators, and operators for formulating and/or revisiting nuclear security policy, regulation, and governance if gap exists.

在这项研究工作中，提出了针对日益增长的对核设施的民用无人机威胁的可能技术解决方案。说明了用于以检测方式应对民用无人机威胁的概念性系统架构，以及主要类型的效应器和缓解系统。通过对研发活动和文献的调查，以找到一种可靠的技术解决方案，已经提出了结合射频（RF）发射和声音事件检测以及基于干扰的物理保护系统（PPS）来应对无人机威胁并解决实时警报和响应。系统架构还根据可用的测试手段和技术，概述了涉及破坏性和非破坏性技术的响应系统的标准。该解决方案可用于升级现有核设施的PPS并设计新进入国家（如孟加拉国）的核设施的PPS，在这些国家中可能没有考虑将无人机威胁与其他威胁属性结合使用。该文件将使政策制定者，监管者和运营商能够在存在差距的情况下制定和/或重新审查核安全政策，法规和治理。
