• Detailed understanding of the design and function of a thermonuclear weapon, including the primary fission stage, the secondary fusion stage, and the interstage radiation case (Hohlraum), and their impact on weapon yield.

Nuclear Weapon Effects

• Examination of the immediate and long-term effects of a nuclear detonation, including blast waves, thermal radiation, prompt nuclear radiation (neutrons and gamma rays), and electromagnetic pulse (EMP).
• Quantitative analysis of the scaling laws for blast effects (e.g., Sachs scaling), thermal radiation fluence, and radiation dose as a function of yield, height of burst, and atmospheric conditions.
• Analysis of the impact of a nuclear detonation on infrastructure, including buildings, transportation systems, communication networks, and electronic devices, with emphasis on the effects of EMP.

Nuclear Weapons Strategy and Doctrine

Deterrence Theory and Nuclear Strategy

• In-depth analysis of deterrence theory, including Minimum Deterrence, Assured Destruction, and Flexible Response strategies, and their implications for nuclear force posture and targeting policies.
• Examination of the concept of Mutually Assured Destruction (MAD) and its role in preventing nuclear war, including its critiques and alternative strategies, such as Damage Limitation and Counterforce.
• Analysis of escalation dynamics and crisis stability in nuclear confrontations, including the role of strategic communication, signaling, and arms control agreements in managing escalation risks.

Nuclear Proliferation and Counterproliferation

• Detailed examination of the history and drivers of nuclear proliferation, including the role of national security concerns, prestige, and technological diffusion.
• Analysis of the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA) safeguards system, including its strengths, weaknesses, and challenges in preventing nuclear proliferation.
• Study of counterproliferation strategies, including diplomacy, sanctions, export controls, and military options, and their effectiveness in preventing or reversing nuclear proliferation.

Arms Control and Disarmament

• Comprehensive overview of arms control treaties and agreements, including the Strategic Arms Limitation Talks (SALT), the Strategic Arms Reduction Treaty (START), the Intermediate-Range Nuclear Forces (INF) Treaty, and the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
• Analysis of the challenges and opportunities for nuclear disarmament, including the role of verification, transparency, and political will in achieving further reductions in nuclear arsenals.
• Examination of alternative approaches to arms control, such as Cooperative Threat Reduction (CTR) programs and fissile material cut-off treaties, and their potential for reducing nuclear dangers.

Nuclear Weapons Management and Security

Nuclear Command and Control Systems

• Detailed analysis of nuclear command and control (C2) systems, including their architecture, communication networks, decision-making processes, and safeguards against unauthorized use.
• Examination of the Permissive Action Link (PAL) system and other technical measures designed to prevent accidental or unauthorized detonation of nuclear weapons.
• Study of the challenges of maintaining secure and reliable nuclear C2 systems in the face of cyber threats, technological obsolescence, and political instability.

Nuclear Materials Management and Security

• Comprehensive overview of nuclear materials management, including the storage, transportation, and accounting of fissile materials, such as highly enriched uranium (HEU) and plutonium.
• Analysis of the threats to nuclear materials security, including theft, diversion, and sabotage, and the measures implemented to prevent such incidents.
• Examination of international standards and best practices for nuclear materials security, including the IAEA's Nuclear Security Recommendations and the Global Partnership Against the Spread of Weapons and Materials of Mass Destruction.

Nuclear Weapon Accident Response and Emergency Management

• Detailed understanding of the potential causes and consequences of nuclear weapon accidents, including fires, explosions, and dispersal of radioactive materials.
• Examination of emergency response procedures for nuclear weapon accidents, including containment, evacuation, medical treatment, and environmental remediation.
• Analysis of the role of international organizations, such as the IAEA and the World Health Organization (WHO), in providing assistance and expertise in the event of a nuclear weapon accident.
