The Ministry of Science and ICT said on Wednesday that its has signed an agreement with the European Commission on the "Technology Management Plan" (TMP) that involves the test, operation and research of the International Thermonuclear Experimental Reactor (ITER). Their research will focus on reducing the damage inflicted on ITER devices due to the instantaneous collapse of plasma.
Researchers will share test data from KSTAR, South Korea's magnetic fusion device intended to study aspects of magnetic fusion energy, and the Joint European Torus (JET), the world's largest operational magnetically confined plasma physics experiment device, the ministry said.
Seven countries including South Korea, the United States, China and EU members have been involved in the ITER project to build an experimental fusion reactor in Cadarache, France. If the experiment is successful, it could provide mankind with a limitless energy source. ITER facility is expected to be constructed by 2021.
Fusion power, generated by nuclear fusion, has long been spotlighted as a safe next-generation power source capable of reducing radioactivity. However, commercialization has a long way to go because it's extremely difficult to produce a state of controlled fusion. Plasma experiments will begin in 2025 and full deuterium-tritium fusion experiments in 2035.
In February this year, the National Fusion Research Institute (NFRI) said that KSTAR has successfully maintained a plasma center ion temperature of 100 million degrees Celsius for 1.5 seconds. The institute aims to maintain a plasma center ion temperature of 100 million degrees for more than ten seconds.
A high temperature is the most critical operating condition of fusion. The sun's center plasma ion density is so high that nuclear fusion occurs at 15 million degrees, but plasma ion temperatures should be over 100 million degrees on Earth with much less gravity to cause fusion reactions.
