Question

What is a nuclear accident? Mention two points that should be taken into account while designing a nuclear reactor.

Answer 1

Nuclear accident: The International Atomic Energy Agency defines a nuclear or radiation accident as "an occurrence that has resulted in substantial consequences for people, the environment, or the facility."

The following two points should be taken into account while designing a nuclear reactor:

1. The safety rod system quickly put the reactor into a subcritical state and prevents a supercritical accident.
2. The containment structure prevents radioactive materials from being released into the atmosphere.
