Question

First nuclear reactor was built in

• A. Russia
• B. U.S.A.
• C. U.K.
• D. France

Answer 1

The correct option is B U.S.A.

Chicago Pile 1 was the world's first nuclear reactor, built in 1942 by Nobel Prize winner Enrico Fermi. The reactor was built underneath the University of Chicago's Stagg Field football stadium. The experimental reactor was built during the height of World War II as part of the Manhattan Project, the army's nuclear weapons program. The primary purpose for the largest reactors (Washington), was the mass production of plutonium for nuclear weapons. Fermi and Szilard applied for a patent on reactors on 19 December 1944. Its issuance was delayed for 10 years because of wartime secrecy.

So the correct answer is 'U.S.A'.
