During Operation of a Nuclear Reactor, the ²³⁸U Nuclei

question 15

Multiple Choice

During operation of a nuclear reactor, the ²³⁸U nuclei

• A) slow down the neutrons, thus improving the efficiency of the reactor.
• B) are fissioned by the neutrons, thus releasing nuclear energy.
• C) absorb neutrons, which causes them to turn into fissionable ²³⁵U.
• D) absorb neutrons, which causes them to turn into plutonium.
• E) absorb neutrons, which slows down the chain reaction and thus controls the reaction.
