The <entity_0> (Bokmål: Tungtvannsaksjonen; Nynorsk: Tungtvassaksjonen) was a series of Allied-led efforts to halt German heavy water production via hydroelectric plants in Nazi Germany-occupied <entity_4> during <entity_2>, involving both Norwegian commandos and Allied bombing raids. The <entity_0> was aimed at the 60 MW <entity_1> power station at the Rjukan waterfall in <entity_3>. Before the German invasion of <entity_4> on 9 April 1940, the French Deuxième Bureau removed 185 kilograms (408 lb) of heavy water from the <entity_1> plant in then-neutral <entity_4>. The Deuxième Bureau (French military intelligence) directed three French agents (Captain Muller and Lieutenants Mossé and Knall-Demars) to remove the world's extant supply, 185 kg (408 lb), of heavy water from the <entity_1> plant in then-neutral <entity_4> in 1940. The 2018 book, Heroes of <entity_3>; Sabotaging Hitler's atomic bomb, <entity_4> 1942–44 by David Greentree (ISBN 9781472827678), describes the operation's planning, execution and aftermath.
