A fission chain reaction in uranium can be developed

Question

RRB Paper · Accepted Answer

When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission. Each time a U-235 nucleus splits, it releases two or three neutrons.

A fission chain reaction in uranium can be developed by increasing the contents of U??? and by slowing down fast neutrons.

Neutrons produced by fission have high energies and move extremely quickly.
These so-called fast neutrons do not cause fission as efficiently as slower-moving ones so they are slowed down in most reactors by the process of moderation

A fission chain reaction in uranium can be developed

By increasing the contents of U???

By slowing down fast neutrons so that U??? fission continues by slow neutron

Both (1) and (2)

None of these

The correct answer is `No. 3: Both (1) and (2)`
