Possibility of Insider Threat to Nuclear Power Plants

Abstract

Nuclear power plants represent critical infrastructure assets essential for global energy production, embodying both immense potential for state and significant risks. This paper examines the possibility of insider threats within nuclear power plants, clarifying the complex interplay among human factors, security measures, and technical vulnerabilities. By synthesizing existing literature, this study explains the multifaceted nature of insider threats, encompassing malicious actions by employees, contractors, or other trusted entities operating within the facility. The analysis delves into various dimensions of insider threats, primarily focusing on the motivation, capabilities, and intentions of insiders to attempt unauthorized removal or sabotage of nuclear or other radioactive material. This study also examines the main attributes of insider threats, i.e., access, authority, and knowledge. Drawing upon insights from security and radiation protection disciplines, this paper explores the behavioral and organizational factors that contribute to insider risk, emphasizing the importance of understanding human dynamics in safeguarding nuclear facilities. Furthermore, this study assesses the efficacy of existing security measures in mitigating insider threats and identifies areas for improvement. In this paper, we examine strategies ranging from access controls and background checks to personnel screening and psychological profiling, evaluating their strengths, limitations, and ethical considerations. This also includes analyses of pathways through which insiders may exploit vulnerabilities to compromise plant security. Through a comprehensive examination of insider threat scenarios and countermeasures, this paper underscores the imperative for a multidisciplinary approach to nuclear plant security, integrating technical, procedural, and human-centered elements. It advocates for enhanced training and awareness programs to cultivate a culture of vigilance among plant personnel and stakeholders, emphasizing the shared responsibility of safeguarding nuclear facilities against insider threats. Central to this approach is the promotion of a robust nuclear security culture, fostering a mindset of continuous improvement and adherence to best practices in security protocols and risk mitigation strategies.
