Question # 1

Differentiate between controlled and uncontrolled reaction.

Ans 1: To maintain a sustained controlled nuclear reaction,for every 2 or 3 neutrons released ,only one must be allowed to strike another uranium nucleus.it is called controlled chain reaction.
Ans 2: If more than one neutron produces further fission then it will grow uncontrolled and called uncontrolled chain reaction.
