Which is the only nuclear fuel that occurs in nature in abundantly?(a)

1.	Which is the only nuclear fuel that occurs in nature in abundantly?(a) Plutonium(b) Radium(c) Thorium(d) UraniumI had been asked this question in final exam.I would like to ask this question from Gaseous Fuels & Nuclear Fuels topic in portion Steam Power Plant of Energy Engineering
Answer» RIGHT option is (d) Uranium For explanation: Uranium is the only fissionable nuclear fuel occurring in NATURE. It consists of 99.3% of 92U^238, 0.7% 92U^235 and small traces of 92U^234. Out of these isotopes only 92U^235 is used in fission REACTION. Uranium is a very heavy metal which has been used as an ABUNDANT source of concentrated energy for 60 years.
