Abstract:
Cyberattacks against the digital instrumentation and control (DI&C) systems in nuclear power plants (NPPs) are of grave security concern. The US Nuclear Regulatory Commission (NRC) requires all NPPs to protect critical digital assets that support safety, security, and emergency preparedness functions against cyberattacks.1 Other standards bodies like the International Society of Automation (ISA) and the International Electrotechnical Commission (IEC) have also developed standards that address cybersecurity for industrial control systems (ICS) including DI&C.2 Due to concerns for security, relevant stakeholders such as regulators, plant operators, information technology (IT) and operation technology (OT) staff, and equipment suppliers are sometimes reluctant to reveal in technical detail about vulnerabilities posed by DI&C systems. Yet, because some types of cyberattacks against an NPP may cause core damage or significant release of radioactivity, harming the plant, the public and the industry, the safety implications of potential cyberattacks should be evaluated. This divide between security and safety is a challenge for stakeholders focused in cyber security for NPPs. To bridge this security and safety divide, this study proposes and demonstrates a methodology for assessing and addressing the safety consequences of cyber events that disrupt one or more parts of the DI&C systems at NPPs. The methodology builds on the “effect-centric” cyber risk assessment framework developed by the Center for International and Security Studies at Maryland (CISSM). It is used to analyze two historical cyberattacks and one hypothetical attack scenario. As the focus is on plant safety, these assessment, evaluation, and analysis can be candidly and openly discussed with the goal of finding the best defense to thwart the specific cyberattack.

2. Increasing Nuclear Threats through Strategic Missile Defense

Abstract:
Growing concerns about third-country nuclear threats led the United States to withdraw from the ABM Treaty’s constraints on the size and scope of ballistic missile defense arsenals in 2002. Inaccurate and alarmist projections of “rogue state” ICBM threats were critical in winning support for the decision to withdraw from the treaty and to sustain the multi-billion dollar annual price tag for developing, deploying, and expanding strategic missile defenses. But 18 years after Washington abandoned the treaty, North Korea is the only rogue state that could pose a near-term nuclear threat against the American homeland—and U.S. missile defense interceptors and radars have not even delivered high confidence of being able to protect against this threat. Meanwhile, the absence of limits on U.S. strategic missile defenses and prudent, worst-case concerns in Moscow and Beijing about their future expansion are fueling resistance to additional nuclear arms reductions and stability measures. The end result is that the exponential threats posed by Russia and China are getting worse and the chances of a disastrous nuclear arms race are increasing. This analysis argues that the nuclear threat confronting the United States is multilateral, three-dimensional, and interrelated. Unless the United States acknowledges the role of missile defenses in this complicated reality, it will not be able to realize the full benefits that arms control offers.

3. China’s evolving nuclear 
export control regime

Abstract:
The Chinese nuclear industry is actively pursuing international trade under China’s new “Go Global” policy. This development could strain Chinese nuclear export control systems in the coming decades. This paper investigates the evolution of the Chinese nuclear export control regime from the late 1970s to the present, describes the current state of the Chinese export control system, and investigates recent Chinese efforts to build a more robust system. It finds that although the Chinese strategic export control systems have grown tremendously since they first took shape and the capacity of the government to implement these controls has grown as well, significant improvements in both the legal basis for the controls and the capacity of institutions involved are still needed, including in how current laws define exports, in how government bodies are equipped to investigate violations, and in how violations are prosecuted. The Ministry of the Commerce is preparing a new “Export Control Law” that is expected to come into effect soon and to provide the basis for more robust controls that address many of the deficiencies identified above. The Chinese government’s growing commitment to undertaking its international obligations and safeguarding the peaceful use of nuclear energy provides reason for optimism, but in the near term, the effectiveness of these corrective efforts will depend on the completion, implementation, and enforcement of the new law.

4. Do as I Say, and as I Do: 
Chinese Leadership in Nuclear Security

Abstract:
This paper analyzes China’s words and actions regarding the Nuclear Security Summits to better understand what Chinese leadership on nuclear security could look like in the future. It finds that China accomplished the many things it said it would do during the summit process. The paper also explores how China’s policy and actions in other nuclear arenas could be paired with Chinese nuclear security policy to form a coherent agenda for nuclear risk reduction writ large. Consequently, the paper addresses how China doing as it says and does – per nuclear security – may be used as a way in which to inform its future nuclear security roles and responsibilities. In particular, it assesses China’s opportunities to assume a leadership role within this crucial international security issue area, especially at a time where U.S. leadership has waned.
