What is supercritical reaction?
a. A reaction in a nuclear reactor that is about to fail because of fuel depletion. b. A chain reaction that would simply die out because not enough neutrons are being absorbed by uranium-235. c. A chain reaction that grows rapidly because an average of more than one neutron from each fission reaction causes another fission reaction. d. A chain reaction based on plutonium. e. One that can continue indefinitely.
