Lockheed compact fusion reactor design about 100 times larger than first plans

Posted by in categories: engineering, nuclear energy

There is updated technical information on the Lockheed compact fusion reactor project. It was originally believed that the compact reactor would fit on a large truck. It looked like it might weigh 20 tons. After more engineering and scientific research, the new design requires about 2000 ton reactor that is 7 meters in diameter and 18 meters long. This would be about one third the length of a Dolphin diesel submarine and it would be slightly wider and taller. It would be similar in size to a A5W submarine nuclear fission reactor. We would not know for sure because the A5W size is classified but based on the size and likely configuration of a nuclear submarine this size estimate is likely.

They have performed simulations. In simulations, plasma confinement is achieved in magnetic wells with self – produced sharp magnetic field boundaries. • Design closes for 200 MW th reactor, 18 meters long by 7 meters diameter device assuming hybrid gyro – radii sheath and cusp widths and good coil support magnetic shielding. • Neutral beam heats plasma to ignited state. • The dominant losses are ion losses through the ring cusps into stalks and axially through the mirror confined sheath. • Good global curvature gives interchange stability.

Lockheed believes they can get better confinement at the cusps than the EMC2 polywell reactor.
