What is ITER and what is its primary scientific objective?

• A. A coal-fired power plant
• B. A space reactor
• C. International Thermonuclear Experimental Reactor designed to demonstrate net energy gain from fusion
• D. A fission research reactor

Answer: (C)

ITER is the International Thermonuclear Experimental Reactor, a large magnetic confinement fusion device built by an international collaboration. Its main objective is to demonstrate net energy gain from fusion—producing more energy from fusion reactions than is put into heating and sustaining the plasma (a result known as Q greater than 1). In practical terms, ITER aims for about 500 MW of fusion power from roughly 50 MW of external heating, achieving a plasma energy gain around tenfold, which would prove that sustained, controlled fusion is scientifically and technically feasible. This experiment also tests burning-plasma physics, materials, and technology needed for future fusion power plants. It is not a coal-fired plant, a space reactor, or a fission reactor; it is an experimental fusion facility designed to advance toward practical fusion energy.
