Multiple choice

What is the most common type of deep geological repository for nuclear waste?

  1. Hard rock repository

  2. Clay repository

  3. Salt repository

  4. Granite repository
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The most common type of deep geological repository for nuclear waste is a hard rock repository. Hard rock repositories are located in stable geological formations, such as granite or gneiss. Hard rock repositories are designed to isolate nuclear waste from the environment for thousands of years.
