Norwegian heavy water sabotage - Wikipedia. The Norwegian heavy water sabotage (Bokmål: Tungtvannsaksjonen, Nynorsk: Tungtvassaksjonen) was a series of operations undertaken by Norwegian saboteurs during World War II to prevent the German nuclear weapon project from acquiring heavy water (deuterium oxide), which could have been used by the Germans to produce nuclear weapons. In 1. 93. 4, at Vemork, Norway, Norsk Hydro built the first commercial plant capable of producing heavy water as a byproduct of fertilizer production. It had a capacity of 1. During World War II, the Allies decided to remove the heavy water supply and destroy the heavy water plant in order to inhibit the German development of nuclear weapons. Raids were aimed at the 6.

MW Vemork power station at the Rjukan waterfall in Telemark, Norway. Prior to the German invasion of Norway on 9 April 1.

Deuxième Bureau (French military intelligence) removed 1. Vemork in then- neutral Norway.

The plant's managing director, Aubert, agreed to lend the heavy water to France for the duration of the war. The French transported it secretly to Oslo, to Perth, Scotland, and then to France. The plant remained capable of producing heavy water.[1]The Allies remained concerned that the occupation forces would use the facility to produce more heavy water for their weapons programme.

Between 1. 94. 0 and 1. Norwegian resistance movement—as well as Allied bombing—ensured the destruction of the plant and the loss of the heavy water produced. These operations—codenamed Grouse, Freshman, and Gunnerside—finally managed to knock the plant out of production in early 1. In Operation Grouse, the British Special Operations Executive (SOE) successfully placed four Norwegian nationals as an advance team in the region of the Hardanger Plateau above the plant in October 1.

The unsuccessful Operation Freshman was mounted the following month by British paratroopers; they were to rendezvous with the Norwegians of Operation Grouse and proceed to Vemork. This attempt failed when the military gliders crashed short of their destination, as did one of the tugs, a Handley Page Halifax bomber. The other Halifax returned to base, but all the other participants were killed in the crashes or captured, interrogated, and executed by the Gestapo. In February 1. 94.

SOE- trained Norwegian commandos succeeded in destroying the production facility with a second attempt, Operation Gunnerside. Operation Gunnerside was later evaluated by SOE as the most successful act of sabotage in all of World War II.[2]These actions were followed by Allied bombing raids. The Germans elected to cease operation and remove the remaining heavy water to Germany. Norwegian resistance forces sank the ferry, SF Hydro, on Lake Tinn, preventing the heavy water from being removed.

Technical background[edit]. The experimental apparatus with which the chemists Otto Hahn and Fritz Strassmann discovered nuclear fission of uranium in 1.

Enrico Fermi and his colleagues studied the results of bombarding uranium with neutrons in 1. The first person who mentioned the idea of nuclear fission in 1. Ida Noddack.[4] Four years after the Fermi publication, in December 1. Lise Meitner and Otto Frisch correctly interpreted the radiochemical experimental results of Otto Hahn and Fritz Strassmann as evidence of nuclear fission.

News of this discovery spread quickly among physicists and it was realised that if chain reactions could be controlled, fission might lead to a new source of great power. What was needed was a substance that could "moderate" the energy of neutrons emitted in radioactive decay, so that they could be captured by other fissile nuclei. Heavy water and graphite were the prime candidates for moderating the energy of neutrons.[5]When Nazi Germany investigated the production of an atomic bomb (see German nuclear energy project), a range of options was identified.

Although historical records provide limited detail on the German decision to pursue the heavy water approach, it became clear after the war that they had explored the option.[6][7] Although ultimately unsuccessful, the approach chosen has been demonstrated to be technically viable: Plutonium- 2. Pu) makes an effective weapons material (although requiring an implosion- type mechanism as a simpler Thin Mangun- type bomb is not feasible). Heavy water has been demonstrated as an effective moderator for 2. Pu production. Heavy water may be separated from ordinary water by electrolysis. Approaches to developing a weapon[edit]In nuclear weapon development, the main problem is securing sufficient "weapons grade" material.

In particular, it is difficult to acquire either fissileisotopes of uranium- 2. U) or of 2. 39. Pu. Weapons grade uranium requires mining, extracting and enriching natural ore.

Alternatively, plutonium can be "bred" in reactors fueled by unenriched uranium, which requires chemical separation of the 2. Pu produced. Unlike the Allies, who pursued both the enrichment of uranium and the production of plutonium, German scientists only focused on plutonium production[citation needed], as this method was less expensive. Plutonium production[edit]Although the most common isotope of uranium, uranium- 2. U), can be used as secondary fissionable material in hydrogen bombs, it cannot be used as the primary fissile material for an atomic bomb.

U can be used to produce 2. Pu, through the fission of 2. U which produces neutrons, some of which will be absorbed by 2.

U creating 2. 39. U. After a few days the 2. U will decay, turning into weapons- usable 2. Pu. The Germans did not examine ultra- pure graphite because they did not know that the graphite they had tried was too impure to sustain a chain reaction, and abandoned it as a possible moderator. They instead settled on the heavy- water- based reactor design.[8] A heavy water moderated nuclear reactor could be used to do nuclear fission research, and, ultimately, to breed plutonium from which a bomb could be constructed.

Heavy water production[edit]In normal water, there is only one deuterium atom for every 6. An analysis of the residues from the Vemork hydroelectric plant, a large- scale hydrogen production plant using electrolysis of water for ammonia production, showed a hydrogen/deuterium ratio of 4. HDO molecules.[9]Leif Tronstad, then a lecturer at the Norwegian Institute of Technology and Jomar Brun, head of the hydrogen plant put forward a proposal in 1. Norsk Hydro and production started in 1. The technology is straightforward. Heavy water (D2. O) is separated from normal water by electrolysis because the difference in mass between the two hydrogen isotopes translates into a slight difference in the speed at which the reaction proceeds. To produce pure heavy water by electrolysis requires a large cascade of electrolysis chambers, and consumes large amounts of power.

Since there was excess power available, heavy water could be purified from the existing electrolyte. As a result, Norsk Hydro became the heavy water supplier for the world's scientific community, as a by- product of fertilizer production, for which the ammonia was used.[1. Hans Suess was a German adviser to the production of heavy water. Suess had assessed the Vemork plant as being incapable of producing militarily useful quantities of heavy water in less than five years at its then capacity.[1]Operations to limit German access to heavy water[edit]Pre- invasion efforts[edit]French research considered production of 2.
