Can thorium replace coal and uranium? City Press

WebAug 3, 2024 · Uranium, thorium, Carbon-14, and their daughter elements (or decay products) produce most of the radioactivity found while rockhounding. You find trace amounts of them in granite and other igneous rocks. These rocks come from deep into the Earth’s mantle and core where they are responsible for most of the internet heat. WebOct 5, 2024 · A thorium fuel cycle could reduce the production of nuclear waste from nuclear power. However, contrary to what some proponents of the thorium fuel cycle might state, a thorium fuel cycle does not remove the need for a long-term disposition pathway for high-level nuclear waste. The waste produced in the thorium fuel cycle is more stable than ... download new themes and desktop backgrounds
