Fusion Energy In South Korea

What is Fusion Energy?

Fusion energy is the process of generating power by fusing atomic nuclei, a reaction that powers the sun and stars. Unlike nuclear fission, which splits atoms and produces long-lived radioactive waste, fusion combines lighter elements like hydrogen isotopes to form heavier elements, releasing immense amounts of energy in the process. This makes fusion energy a cleaner and safer alternative to traditional nuclear power.

In South Korea, fusion energy research is primarily focused on harnessing this reaction in a controlled environment to produce electricity. The country has invested heavily in tokamak reactors, which use magnetic fields to confine plasma at extremely high temperatures and pressures, mimicking the conditions found in the sun.

Key Principles Behind Fusion Energy

The principles of fusion energy revolve around three key elements: temperature, pressure, and confinement. For fusion to occur, the plasma must reach temperatures exceeding 100 million degrees Celsius, a feat that requires advanced materials and technologies. High pressure is also essential to bring the atomic nuclei close enough to overcome their natural repulsion. Finally, confinement ensures that the plasma remains stable long enough for the fusion reaction to occur.

South Korea's approach to these principles is exemplified by its flagship project, the Korea Superconducting Tokamak Advanced Research (KSTAR) reactor. Known as the "Korean artificial sun," KSTAR has achieved record-breaking plasma confinement times, showcasing the country's expertise in fusion technology.
