International Nuclear and Radiological Event Scale

Target entity: International Nuclear and Radiological Event Scale
Context triple: [INES level 7, partOf, International Nuclear and Radiological Event Scale]

• A. Hazard Ranking System
  The Hazard Ranking System is a scoring tool used by the U.S. Environmental Protection Agency to assess the relative risk of contaminated sites and determine which ones qualify for inclusion on the Superfund National Priorities List.
• B. NRX reactor accident of 1952
  The NRX reactor accident of 1952 was a major nuclear reactor incident in Canada involving a partial meltdown and significant radioactive release, making it one of the earliest serious accidents in nuclear power history.
• C. IAEA Safety Standards Series
  The IAEA Safety Standards Series is a collection of internationally agreed guidelines and requirements issued by the International Atomic Energy Agency to ensure the safe use of nuclear energy and radiation worldwide.
• D. 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.
• E. K-East Reactor
  K-East Reactor was one of the plutonium production reactors at the Hanford Site in Washington State, built during the Cold War to support the U.S. nuclear weapons program.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
