Question 2
During operation of a nuclear reactor, the 238U nuclei
A) absorb neutrons, which causes them to turn into plutonium.
B) slow down the neutrons, thus improving the efficiency of the reactor.
C) absorb neutrons, which causes them to turn into fissionable 235U.
D) absorb neutrons, which slows down the chain reaction and thus controls the reaction.
E) are fissioned by the neutrons, thus releasing nuclear energy.
