Question
(A) Which of the following statements about the uranium used in nuclear reactors is or are true?
Check all that apply.
The neutron-induced fission of 235U releases more neutrons per nucleus than fission of 238U.
(B) Which of the following statements about the plutonium shown in the chapter-opening photograph explains why it cannot be used for nuclear power plants or nuclear weapons?
The neutron-induced fission of 235U releases more neutrons per nucleus than fission of 238U.
238U cannot be used as a fuel because it forms a supercritical mass too easily. To be used as fuel, uranium must be enriched so that it is more than 50% 235U in composition. Natural uranium has too little 235U to be used as a fuel.Explanation / Answer
