Question

The fuel in atomic pile is
A) Carbon
B) Sodium
C) Petroleum
D) Uranium

Answer 1

Hint- we must have understood that an atomic pile is an early type of nuclear reactor whose core consisted of alternating layers of uranium pellets and graphite bricks, designed to create a sustained fission reaction.

Complete Step by step answer:
We must remember that the fuel used in an atomic pile is uranium. We have to know about the atomic pile device. Therefore, it is a device that’s used to control the nuclear fission to generate energy in nuclear reactors. The most common reactor consists of a large assembly of graphite blocks having rods of uranium metal.
Also we remember that the uranium is more radioactive and easily fission. So we can use it as a fuel in nuclear power plants. Although uranium is about 100 times more common than silver, \[{{\text{U}}^{{\text{235}}}}\]is relatively rare.
Additional information:
We must know that we found only 1% of easily fissionable U-235 isotope uranium in nature. And enrichment involves increasing the percentage of U-235 and is usually done by means of gas centrifuge. The enriched result is converted to uranium powder, which is pressed and fired into pellet form. These pellets are stacked into tubes which are then sealed and are called fuel rods. We can use these fuel rods in all types of nuclear reactors as fuel.

Notes: We must know that the nucleus of U-235 isotope comprises 92 protons and 143 neutrons. When the nucleus of a U-235 atom is fissioned by a neutron, it gets fission. That will release some energy in the form of heat.
