These facilities can be set up with engineered barriers, or without the engineered barriers. When nuclear waste (LLW) is stored at surface level, there is a protective

covering placed over the materials that is a few meters thick. The wasted containers are put in vaults, and after the vaults are filled, and then they are backfilled.
