Reactor No. 4

Target entity: Reactor No. 4
Context triple: [Chernobyl disaster, reactorInvolved, Reactor No. 4]

• A. K-West Reactor
  K-West Reactor is one of the plutonium production reactors at the Hanford Site in Washington State, historically used to support the U.S. nuclear weapons program.
• B. K Reactor
  K Reactor is a decommissioned nuclear production reactor at the Savannah River Site in South Carolina that was used primarily for producing weapons-grade materials during the Cold War.
• C. D Reactor
  D Reactor was one of the early plutonium production reactors at the Hanford Site in Washington, built during the Manhattan Project to support the U.S. nuclear weapons program.
• D. X-10 graphite reactor
  The X-10 graphite reactor was an early nuclear reactor at Oak Ridge, Tennessee, built during the Manhattan Project as a pilot plant for plutonium production and a key step toward the development of nuclear weapons and nuclear energy.
• E. TRIGA research reactor
  The TRIGA research reactor is a small, inherently safe nuclear reactor design widely used in universities and research institutions for education, training, and scientific experiments.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Reactor No. 4
Target entity description: Reactor No. 4 was the RBMK nuclear reactor at the Chernobyl Nuclear Power Plant whose catastrophic explosion in 1986 caused one of the worst nuclear disasters in history.
