Nuclear Fusion & Superconductivity Technology Lab

Thank you for visiting Nuclear Fusion & Superconductivity Technology Lab.

Based on more than 25 years of experiences in the organizations developing nuclear fusion energy both domestically (for KSTAR) and internationally (for ITER), we expect to continue the research on advanced fusion technologies for energy industry. Our technical experience and human networks will help to establish future research collaborations domestically and internationally.
Our goal is to fabricate(and test) the superconducting magnets for the next generation fusion demonstration reactor in Korea, called K-DEMO. The recent status of K-DEMO is a preliminary conceptual design phase and there are many research activities to be carried out.

Fusion in the Stars

The Sun and all stars generate tremendous amounts of fusion power burning plasmas of hydrogen

Fusion is the natural energy choice!

The Sun uses its massive size and gravity to confine the plasma with a confinement time of ~170,000 years!

Fusion Research

The temperature of the ions in a plasma has to be so high that there is no possibility of containing the hot plasma in any conventional vessel on Earth.

Magnetic confinement :: A magnetic field forms a barrier between the hot fuel and the wall.; The electrical charges on ions and electrons prevent them from moving directly across a magnetic field.; We will use magnetic confinement by using magnetic fields called Tokamak option.; Charged particles are trapped along the B-field line; In this way a magnetic field can be used to guide the charged particles

Magnetic Confinement (TOKAMAK)

The function of the magnets is to form, control and drive the tokamak plasma.

Poloidal Field(Bp) could be generated by plasma current(Ip)

Bp and BT generate Helical field

This helical field can make stable plasma

TF, PF, CS coils are needed

Superconducting K-DEMO Tokamak

In a superconductor, the resistance drops to zero when the material is cooled below its critical temperature (~4 K ).

Superconducting magnets, once cooled and energized can run continuously and electricity is only required to run the cryogenic coolant.

Compared with copper magnets, superconducting magnets can produce greater magnetic fields, enable much longer plasma pulses and require less energy to operate because no energy is dissipated as heat in the windings.

Our Goal is to fabricate(and test) the superconducting magnets for future nuclear fusion reactor, called K-DEMO. The recent status of K-DEMO is a preliminary conceptual design phase and there are many research activities to be carried out.

Nuclear fusion & Superconducting high field magnet Lab

Thank you for visiting Nuclear fusion and High field magnet lab.

Our Goal is to fabricate(and test) the superconducting magnets for the next generation fusion demonstration reactor in Korea, called K-DEMO. The recent status of K-demo is a preliminary conceptual design phase and there are many research activities to be solved.

The K-DEMO is being actively discussed worldwide to further accelerate the commercialization of fusion energy. Based on the so-called fast track approach, EU, Japan and USA have revised their roadmaps so that an economically viable demonstration fusion power plant can be operated during the 2040. A similar strategy is adopted in Korea as was announced in a National Fusion Roadmap released in 2005. Furthermore, Fusion Energy Development Promotion Law (FEDPL), the first legal act in the world for fusion energy development, was enacted in 2007 to promote long-term cooperative fusion research and development among participating industries, universities and research institutes. As a following step, a preliminary design study for K-DEMO is underway targeting the construction by 2037. The recent status of K-demo is a preliminary conceptual design phase and there are many research activities to be solved.
