ANEUTRONIC FUSION Meaning and
Definition
-
Aneutronic fusion refers to a type of nuclear fusion reaction where the majority of the energy generated arises from the collision and subsequent fusion of atomic nuclei that contain little or no neutrons. In other words, aneutronic fusion reactions primarily involve the fusion of proton and boron-11 nuclei or proton and helium-3 nuclei.
Unlike conventional fusion reactions, such as the fusion of deuterium and tritium, aneutronic fusion does not require a large amount of high-energy neutrons to initiate and sustain the fusion process. Instead, aneutronic fusion reactions release energy in the form of charged particles, such as protons or alpha particles, which can be directly converted into electricity using suitable capture mechanisms.
The absence of significant neutron production is a major advantage of aneutronic fusion, as it reduces the associated radiation hazards. Furthermore, aneutronic fusion reactions tend to have higher energy conversion efficiencies compared to conventional fusion, making them potentially more attractive from an electricity generation perspective.
However, aneutronic fusion presents considerable technical challenges, as it necessitates the creation of conditions where the fusion of nuclei emitting little or no neutrons occurs at a sufficiently high rate and temperature. Despite these challenges, researchers continue to explore aneutronic fusion as a potentially viable future source of clean and abundant energy.
Etymology of ANEUTRONIC FUSION
The word "aneutronic fusion" can be broken down into two parts: "aneutronic" and "fusion".
The term "aneutronic" comes from the prefix "a-", meaning "not", and the word "eutronic". "Eutronic" is derived from the Greek word "eu" meaning "good" and the English word "tronic", referring to a system or device powered by electrons. Therefore, "aneutronic" suggests a system that is not powered by electrons or lacks the presence of electrons.
The word "fusion" comes from the Latin word "fusio", which means "a pouring out" or "a melting". In the context of nuclear physics, fusion refers to the process of combining two light atomic nuclei to form a heavier element, releasing a tremendous amount of energy in the process.
