Q. |
In a nuclear reactor, one of the following is used as a fuel. |
A. | Coal |
B. | Uranium |
C. | Radium |
D. | Diesel |
Answer» B. Uranium | |
Explanation: Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 has the distinction of being the only naturally occurring fissile isotope. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. |
