Question

What are the ways in which most of radio activeness is removed?

(a) Infusing them with other metal

(b) Neutralizing them by diluting in chemical solutions

(c) Storing them

(d) Segregating them into small packs

This question was addressed to me during an online interview.

I want to ask this question from Disposal of Nuclear Waste in chapter Nuclear Power Plant of Energy Engineering

Answer 1

The correct choice is (c) Storing them

For explanation I would say: Most of the radio activeness of waste is removed just by storage. The storage problem is simplified by separating cersium and strontium which are extremely radioactive. These are generally stored in tanks which are buried in ground and then disposed in to the sea after 13 years of storage.
