[6], To the existing $10million plant consisting of 3,215 cells consuming 75MW of hydroelectric power, secondary electrolysis cells were added to increase the deuterium concentration in the water from 2.3% to 99.8%. The American plants operated from 1943 until 1945. But the only resistance, if you can call it that, was a Norwegian plant worker sitting at a desk in the basement.

The cover party took up their positions and the sabotage group made their way swiftly to the target. The property was then conveyed to the newly created Morgantown Ordnance Works, Inc., owned by local industrialist J.W. Heavy water, also known as deuterium oxide, is a crucial element in nuclear energy production as it acts as a moderator in nuclear reactors. This website uses cookies to improve your experience while you navigate through the website. Heavy water is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium, also known as heavy hydrogen, rather than the common hydrogen-1 isotope that makes up most of the hydrogen in ordinary water. At Columbia University in the United States, Enrico Fermi and Le Szilrd attempted to use graphite as a moderator instead. Tronstad had more than just technical expertise.
