Integrated Operational Nuclear Detection System

Target entity: Integrated Operational Nuclear Detection System
Context triple: [Vela nuclear test detection satellites, successor, Integrated Operational Nuclear Detection System]

• A. International Atomic Energy Agency safeguards system
  The International Atomic Energy Agency safeguards system is a global verification regime that uses inspections, monitoring, and accounting measures to ensure that states’ nuclear materials and activities are not diverted to nuclear weapons or other military purposes.
• B. Nonproliferation Test and Evaluation Complex
  The Nonproliferation Test and Evaluation Complex is a specialized U.S. facility used to test, evaluate, and improve technologies and procedures for detecting and countering nuclear and radiological threats.
• C. United States nuclear safety research program
  The United States nuclear safety research program is a government-led initiative focused on experimentally and analytically improving the safety, reliability, and accident response of civilian nuclear reactors and related technologies.
• D. Radiation Assessment Detector
  The Radiation Assessment Detector is a scientific instrument aboard NASA's Curiosity rover designed to measure and characterize the radiation environment on Mars and during the journey through space.
• E. Missile Defense Alarm System
  The Missile Defense Alarm System was an early U.S. military warning network designed to detect and provide alerts of incoming missile attacks before being superseded by more advanced satellite-based systems.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Integrated Operational Nuclear Detection System
Target entity description: The Integrated Operational Nuclear Detection System is a U.S. space-based network designed to detect and characterize nuclear explosions worldwide, succeeding the earlier Vela satellite program.
