SIMPLE

Scientists are studying thorium as a safer alternative to uranium.

CONTEXTUAL

Unlike traditional uranium reactors, molten salt reactors can utilize thorium to produce energy with less long-lived radioactive waste.

COMPLEX

The abundance of thorium in the Earth's crust makes it a potentially significant resource for future nuclear energy production, though its commercial deployment remains limited by current technological constraints.

Synonyms
