Question:

Which of the following statements about the uranium used in nuclear reactors is or are true?

(i) Natural uranium has too little ²³⁵U to be used as a fuel.

(iii) To be used as fuel, uranium must be enriched so that it is more than 50% ²³⁵U in composition.

(iv) The neutron-induced fission of ²³⁵U releases more neutrons per nucleus than fission of ²³⁸U.
