Question

In a nuclear reactor thermal energy is obtained from

Answer 1

Explanation:

a fission of radioactive materials

Answer 2

In a nuclear reactor, thermal energy is obtained from Nuclear fission.

• Nuclear fission is a process in which nuclei get excited and break down into a number of small other nuclei.
• In nuclear reaction generally the uranium atom breaks into smaller nuclei and generates energy.
• It is a chain reaction, initially it needs initiation energy later on the process proceeds in the form of a chain reaction and generates a lot of energy so it is an exothermic reaction too.
