Tritium

Definition

Tritium is a radioactive isotope of hydrogen with one proton and two neutrons, commonly used in nuclear fusion reactions as a fuel. Its unique properties make it a critical component in the fusion process, particularly in the deuterium-tritium fuel cycle, where it contributes to efficient energy generation and power extraction.
