From PPPL: “PPPL teams with South Korea on the forerunner of a commercial fusion power station”

“The U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has joined forces with researchers in South Korea to develop a conceptual design for a pioneering fusion facility in that Asian nation. The proposed device, called K-DEMO, could be completed in the mid-to-late 2030s as the final step before construction of a commercial fusion power plant that would produce clean and abundant energy for generating electricity.

South Korea’s National Fusion Research Institute (NFRI) will fund PPPL’s initial collaboration, which will run for six months, beginning in January, and could be extended.

PPPL will explore cutting-edge designs and technologies that could benefit the U.S. fusion program, and South Korea will gain access to the Laboratory’s deep experience in designing and engineering fusion facilities. These include the National Spherical Torus Experiment (NSTX), PPPL’s leading fusion experiment, which is undergoing a major upgrade.


K-DEMO will be comparable in size to ITER, a seven-story tokamak that the European Union, the United States, South Korea and four other nations are building in Cadarache, France. ITER is to produce 500 million watts of fusion power for 500 seconds by the late 2020s to showcase the feasibility of fusion energy. K-DEMO, by contrast, is to produce some 1 billion watts of power for several weeks on end. “K-DEMO should be just a small step away from a commercial plant in technology and performance,” said Neilson.

Iter paints a bigger picture, but K-Demo has a much larger goal.
