So läuft die Auszahlung. Mitglied werden, Vorteile sichern! At room temperature, pure plutonium is silvery in color but gains a tarnish when oxidized.
The color shown by plutonium solutions depends on both the oxidation state and the nature of the acid anion. Plutonium is a reactive metal. In moist air or moist argon , the metal oxidizes rapidly, producing a mixture of oxides and hydrides.
Plutonium shows enormous, and reversible, reaction rates with pure hydrogen, forming plutonium hydride.
The following oxyhalides are observed: Powders of plutonium, its hydrides and certain oxides like Pu 2 O 3 are pyrophoric , meaning they can ignite spontaneously at ambient temperature and are therefore handled in an inert, dry atmosphere of nitrogen or argon.
Pu 2 O 3 spontaneously heats up and transforms into PuO 2 , which is stable in dry air, but reacts with water vapor when heated. Crucibles used to contain plutonium need to be able to withstand its strongly reducing properties.
Refractory metals such as tantalum and tungsten along with the more stable oxides, borides , carbides , nitrides and silicides can tolerate this.
Melting in an electric arc furnace can be used to produce small ingots of the metal without the need for a crucible. Cerium is used as a chemical simulant of plutonium for development of containment, extraction, and other technologies.
Plutonium is an element in which the 5f electrons are the transition border between delocalized and localized; it is therefore considered one of the most complex elements.
The energy difference between the 6d and 5f subshells is very low. The size of the 5f shell is just enough to allow the electrons to form bonds within the lattice, on the very boundary between localized and bonding behavior.
The proximity of energy levels leads to multiple low-energy electron configurations with near equal energy levels.
The highly directional nature of 5f orbitals is responsible for directional covalent bonds in molecules and complexes of plutonium.
Plutonium can form alloys and intermediate compounds with most other metals. Exceptions include lithium, sodium , potassium , rubidium and caesium of the alkali metals ; and magnesium , calcium, strontium , and barium of the alkaline earth metals ; and europium and ytterbium of the rare earth metals.
Plutonium alloys can be produced by adding a metal to molten plutonium. If the alloying metal is sufficiently reductive, plutonium can be added in the form of oxides or halides.
Trace amounts of plutonium, plutonium, plutonium, and plutonium can be found in nature. Small traces of plutonium, a few parts per trillion , and its decay products are naturally found in some concentrated ores of uranium,  such as the natural nuclear fission reactor in Oklo , Gabon.
When one of these neutrons strikes the nucleus of another U atom, it is absorbed by the atom, which becomes U.
With a relatively short half-life, U decays to Np, which decays into Pu. The latter are generally more useful, because the chemistries of thorium and plutonium are rather similar both are predominantly tetravalent and hence an excess of thorium would not be strong evidence that some of it was formed as a plutonium daughter.
Because Pu also occurs in the decay chain of Pu, it must thus also be present in secular equilibrium , albeit in even tinier quantities. Minute traces of plutonium are usually found in the human body due to the atmospheric and underwater nuclear tests that have been carried out, and to a small number of major nuclear accidents.
Most atmospheric and underwater nuclear testing was stopped by the Limited Test Ban Treaty in , which was signed and ratified by the United States, the United Kingdom, the Soviet Union , and other nations.
Continued atmospheric nuclear weapons testing since by non-treaty nations included those by China atomic bomb test above the Gobi Desert in , hydrogen bomb test in , and follow-on tests , and France tests as recently as the s.
Because it is deliberately manufactured for nuclear weapons and nuclear reactors, plutonium is the most abundant isotope of plutonium by far.
Enrico Fermi and a team of scientists at the University of Rome reported that they had discovered element 94 in The mechanism of fission was then theoretically explained by Lise Meitner and Otto Frisch.
Plutonium specifically, plutonium was first produced and isolated on December 14, , and chemically identified on February 23, , by Glenn T.
A paper documenting the discovery was prepared by the team and sent to the journal Physical Review in March ,  but publication was delayed until a year after the end of World War II due to security concerns.
They calculated that element 94 would be fissile, and had the added advantage of being chemically different from uranium, and could easily be separated from it.
McMillan had recently named the first transuranic element neptunium after the planet Neptune , and suggested that element 94, being the next element in the series, be named for what was then considered the next planet, Pluto.
The chemistry of plutonium was found to resemble uranium after a few months of initial study. On August 20, , a trace quantity of this element was isolated and measured for the first time.
Using theoretical information garnered from the operation of CP-1, DuPont constructed an air-cooled experimental production reactor, known as X, and a pilot chemical separation facility at Oak Ridge.
The separation facility, using methods developed by Glenn T. Seaborg and a team of researchers at the Met Lab, removed plutonium from uranium irradiated in the X reactor.
Information from CP-1 was also useful to Met Lab scientists designing the water-cooled plutonium production reactors for Hanford. Construction at the site began in mid In November some plutonium trifluoride was reduced to create the first sample of plutonium metal: The nuclear properties of plutonium were also studied; researchers found that when it is hit by a neutron it breaks apart fissions by releasing more neutrons and energy.
These neutrons can hit other atoms of plutonium and so on in an exponentially fast chain reaction. This can result in an explosion large enough to destroy a city if enough of the isotope is concentrated to form a critical mass.
During the early stages of research, animals were used to study the effects of radioactive substances on health. Hamilton was looking to answer questions about how plutonium would vary in the body depending on exposure mode oral ingestion, inhalation, absorption through skin , retention rates, and how plutonium would be fixed in tissues and distributed among the various organs.
Hamilton started administering soluble microgram portions of plutonium compounds to rats using different valence states and different methods of introducing the plutonium oral, intravenous, etc.
Eventually, the lab at Chicago also conducted its own plutonium injection experiments using different animals such as mice, rabbits, fish, and even dogs.
The results of the studies at Berkeley and Chicago showed that plutonium's physiological behavior differed significantly from that of radium. The most alarming result was that there was significant deposition of plutonium in the liver and in the "actively metabolizing" portion of bone.
Furthermore, the rate of plutonium elimination in the excreta differed between species of animals by as much as a factor of five.
Such variation made it extremely difficult to estimate what the rate would be for human beings. The three primary research and production sites of the project were the plutonium production facility at what is now the Hanford Site , the uranium enrichment facilities at Oak Ridge, Tennessee , and the weapons research and design laboratory, now known as Los Alamos National Laboratory.
The first production reactor that made plutonium was the X Graphite Reactor. In January , workers laid the foundations for the first chemical separation building, T Plant located in West.
U Plant was used only for training during the Manhattan Project. The separation building in East, B Plant, was completed in February The second facility planned for East was canceled.
Nicknamed Queen Marys by the workers who built them, the separation buildings were awesome canyon-like structures feet long, 65 feet wide, and 80 feet high containing forty process pools.
The interior had an eerie quality as operators behind seven feet of concrete shielding manipulated remote control equipment by looking through television monitors and periscopes from an upper gallery.
Even with massive concrete lids on the process pools, precautions against radiation exposure were necessary and influenced all aspects of plant design.
Plutonium has a high spontaneous fission rate, raising the overall background neutron level of the plutonium sample. The entire plutonium weapon design effort at Los Alamos was soon changed to the more complicated implosion device, code-named " Fat Man ".
With an implosion weapon, plutonium is compressed to a high density with explosive lenses —a technically more daunting task than the simple gun-type design, but necessary to use plutonium for weapons purposes.
Enriched uranium , by contrast, can be used with either method. Construction of the Hanford B Reactor , the first industrial-sized nuclear reactor for the purposes of material production, was completed in March By the end of January , the highly purified plutonium underwent further concentration in the completed chemical isolation building, where remaining impurities were removed successfully.
Los Alamos received its first plutonium from Hanford on February 2. While it was still by no means clear that enough plutonium could be produced for use in bombs by the war's end, Hanford was by early in operation.
Only two years had passed since Col. Franklin Matthias first set up his temporary headquarters on the banks of the Columbia River. According to Kate Brown , the plutonium production plants at Hanford and Mayak in Russia, over a period of four decades, "both released more than million curies of radioactive isotopes into the surrounding environment — twice the amount expelled in the Chernobyl disaster in each instance".
In , a safe was discovered during excavations of a burial trench at the Hanford nuclear site. Inside the safe were various items, including a large glass bottle containing a whitish slurry which was subsequently identified as the oldest sample of weapons-grade plutonium known to exist.
Isotope analysis by Pacific Northwest National Laboratory indicated that the plutonium in the bottle was manufactured in the X Graphite Reactor at Oak Ridge during The first atomic bomb test, codenamed "Trinity" and detonated on July 16, , near Alamogordo, New Mexico , used plutonium as its fissile material.
The overall weapon weighed over 4 tonnes , although it used just 6. Large stockpiles of weapons-grade plutonium were built up by both the Soviet Union and the United States during the Cold War.
Radioactive contamination at the Rocky Flats Plant primarily resulted from two major plutonium fires in and Much lower concentrations of radioactive isotopes were released throughout the operational life of the plant from to Prevailing winds from the plant carried airborne contamination south and east, into populated areas northwest of Denver.
The contamination of the Denver area by plutonium from the fires and other sources was not publicly reported until the s.
According to a study coauthored by Edward Martell , "In the more densely populated areas of Denver, the Pu contamination level in surface soils is several times fallout", and the plutonium contamination "just east of the Rocky Flats plant ranges up to hundreds of times that from nuclear tests".
The plant has since been shut down, with its buildings demolished and completely removed from the site. On March 5, , Energy Secretary Steven Chu told a Senate hearing "the Yucca Mountain site no longer was viewed as an option for storing reactor waste".
During and after the end of World War II, scientists working on the Manhattan Project and other nuclear weapons research projects conducted studies of the effects of plutonium on laboratory animals and human subjects.
In the case of human subjects, this involved injecting solutions containing typically five micrograms of plutonium into hospital patients thought to be either terminally ill, or to have a life expectancy of less than ten years either due to age or chronic disease condition.
From to , eighteen human test subjects were injected with plutonium without informed consent. The tests were used to create diagnostic tools to determine the uptake of plutonium in the body in order to develop safety standards for working with plutonium.
The Plutonium Files chronicles the lives of the subjects of the secret program by naming each person involved and discussing the ethical and medical research conducted in secret by the scientists and doctors.
The episode is now considered to be a serious breach of medical ethics and of the Hippocratic Oath. The government covered up most of these radiation mishaps until , when President Bill Clinton ordered a change of policy and federal agencies then made available relevant records.
The committee issued a controversial report which said that "wrongs were committed" but it did not condemn those who perpetrated them.
The isotope plutonium is a key fissile component in nuclear weapons, due to its ease of fission and availability.
Encasing the bomb's plutonium pit in a tamper an optional layer of dense material decreases the amount of plutonium needed to reach critical mass by reflecting escaping neutrons back into the plutonium core.
The Fat Man plutonium bombs used explosive compression of plutonium to obtain significantly higher densities than normal, combined with a central neutron source to begin the reaction and increase efficiency.
Spent nuclear fuel from normal light water reactors contains plutonium, but it is a mixture of plutonium , , and The mixture is not sufficiently enriched for efficient nuclear weapons, but can be used once as MOX fuel.
If fast neutron reactors are not available the normal case , excess plutonium is usually discarded, and forms the longest-lived component of nuclear waste.
The desire to consume this plutonium and other transuranic fuels and reduce the radiotoxicity of the waste is the usual reason nuclear engineers give to make fast neutron reactors.
Weapons-grade plutonium can be added to the fuel mix. MOX fuel has been in use since the s, and is widely used in Europe. MOX fuel improves total burnup.
Plutonium recovered from spent reactor fuel poses little proliferation hazard, because of excessive contamination with non-fissile plutonium and plutonium Separation of the isotopes is not feasible.
A dedicated reactor operating on very low burnup hence minimal exposure of newly formed plutonium to additional neutrons which causes it to be transformed to heavier isotopes of plutonium is generally required to produce material suitable for use in efficient nuclear weapons.
The IAEA conservatively classifies plutonium of all isotopic vectors as "direct-use" material, that is, "nuclear material that can be used for the manufacture of nuclear explosives components without transmutation or further enrichment".
The isotope plutonium has a half-life of A sheet of paper can be used to shield against the alpha particles emitted by plutonium One kilogram of the isotope can generate about watts of heat.
These characteristics make it well-suited for electrical power generation for devices that must function without direct maintenance for timescales approximating a human lifetime.
It is therefore used in radioisotope thermoelectric generators and radioisotope heater units such as those in the Cassini ,  Voyager , Galileo and New Horizons  space probes, and the Curiosity Mars rover.
The twin Voyager spacecraft were launched in , each containing a watt plutonium power source. Over 30 years later, each source is still producing about watts which allows limited operation of each spacecraft.
Plutonium has also been used successfully to power artificial heart pacemakers , to reduce the risk of repeated surgery.
There are two aspects to the harmful effects of plutonium: Isotopes and compounds of plutonium are radioactive and accumulate in bone marrow.
Contamination by plutonium oxide has resulted from nuclear disasters and radioactive incidents , including military nuclear accidents where nuclear weapons have burned.
During the decay of plutonium, three types of radiation are released—alpha, beta, and gamma. Alpha, beta, and gamma radiation are all forms of ionizing radiation.
Either acute or longer-term exposure carries a danger of serious health outcomes including radiation sickness , genetic damage , cancer , and death.
Veel spelers verlieten de club omdat ze niet in de tweede klasse wilden spelen. De eerste seizoenen kon de club nog met de subtop aan in de tweede klasse, maar zakte langaam weg richting degradatiezone.
In werden de activiteiten gestaakt door het uitbreken van de Tweede Wereldoorlog , vele spelers gingen het leger in.
Het seizoen erna werd de club vijfde en dit volstond niet om opgenomen te worden in de nieuwe Oberliga West , die ging fungeren als een van de vijf hoogste klassen.
Na twee jaar Landesliga, werd de II. Liga West de nieuwe tweede klasse waar de club ging spelen en in werd de club kampioen en promoveerde zo naar de Oberliga.
Het seizoen begon veelbelovend en na de heenronde stond de club op een vierde plaats, met slechts twee punten achterstand op herfstkampioen Schalke 04, maar de terugronde verliep minder gunstig en de club werd uiteindelijk achtste.
Het volgende seizoen werd de club wel vierde en kon winnen tegen grote clubs als 1. De toeschouwersaantallen waren goed, daar het de enige club was die in het Duisburgse grote Wedaustadion mocht spelen.
Er werden geen nieuwe aankopen gedaan en de club vertrouwde op de jeugd, die het echter niet waarmaakte. Pas op de negende speeldag won de club voor de eerste keer en stond lange tijd laatste.
In de terugronde speelde de club vaak gelijk wat tot puntenverlies leidde en uiteindelijk een zevende plaats. Na een vierde plaats het volgende seizoen ging het langzaam bergaf en kwam degradatie nabij.
De club stond aan de winterstop zevende maar werkte zich in de terugronde naar de derde plaats en kwalificeerde zich voor de Bundesliga. Op 24 augustus ging de Bundesliga eindelijk van start en begon met een 4: De club had een uitzonderlijk goed seizoen en werd vicekampioen achter 1.
Het volgende seizoen volgde de ontnuchtering en de club flirtte een tijdlang met de degradatie en redde zich door een sterkere terugronde.
Het was de hoogste uitzege uit de geschiedenis van de Bundesliga en dit record werd tot op heden nog niet verbeterd.
Met zeventig doelpunten dat seizoen was dit ook het seizoen met de meeste doelpunten voor de club, echter eindigde Meiderich pas achtste.
Na 19 jaar in de Bundesliga degradeerden ze in en in zelfs naar de regionale competities. In promoveerden ze weer en in kwamen ze weer in de Bundesliga.
Ze degradeerden meteen weer, maar promoveerden ook meteen weer. In degradeerden ze weer naar de 2. MSV Duisburg blijft zodoende onafgebroken heen en weer pendelen.
