An atomic pile, or more correctly a nuclear pile, uses Uranium235 as the fuel. This isotope of uranium has the property that the nucleus can be split (fissioned) when a slow neutron enters it, and in the fission process more neutrons are emitted together with heat energy, and the formation of fission products which are other elements. Therefore a self perpetuating chain reaction can be started. The neutrons emitted by the fissions are fast and have to be slowed down by the moderator which can be graphite, heavy water, or light water. The rate of fissions is adjusted with control rods which absorb neutrons, or by other neutron absorbing means, so that a steady power level is achieved.
This was built as part of the Manhattan Project in WW2, to demonstrate the principle of the chain reaction. The results were used to design the Hanford piles to produce plutonium. The chief scientist for the Chicago pile was Enrico Fermi, first criticality in 1942

The main principle is that electricity could be sent wireless and he proved it.

The working principle of wind power is exceptionally simple. Wind turns the blades on a windmill and the power that is generated is stored for later use.
An atomic pile is an early form of nuclear reactor fuelled by uranium and moderated with graphite.
It means, "pile." It could mean a pile of wool, a pile driven into the ground, a Voltaic pile (battery), or an atomic pile (nuclear reactor).

What is the working principle of venturimeter?
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
Enrico Fermi
A principle is a way of working or ethical standards.
