Nuclear Power Applications

Plutonium is indispensable in the nuclear power sector.

• Nuclear Reactors: It’s primarily used as fuel in nuclear power plants due to its capability to sustain nuclear chain reactions.
• Mixed Oxide Fuel (MOX): A blend of plutonium and natural or depleted uranium used in some reactors. MOX helps reduce nuclear waste by reusing plutonium.
• Nuclear Weapons: Plutonium-239 is a critical isotope in the production of nuclear weapons due to its quick chain reactions.
