amount of material is needed. This amount is known as the critical mass. If the amount is too small it is called a subcritical mass. The critical mass of a material depends on its purity. The materials used in making fission weapons are uranium and plutonium. They are the only elements able to be used in making a fission weapon. The destructive power in fusion weapons comes from the combining of very light atoms‚ such as hydrogen. The atoms of the element are fused‚ and they release a great amount

Kerr-McGee‚ was the inspiration for hundreds of articles‚ several books‚ televisions shows‚ and a movie. In the early 1970s‚ Silkwood worked as a lab analyst in an Oklahoma Kerr-McGee plant which manufactured plutonium pins used as fuel for nuclear reactors (The Karen Silkwood Story‚ 2004).. Plutonium‚ a radioactive chemical element‚ is known to be highly toxic and carcinogenic. Silkwood‚ an elected union official and outspoken critic of Kerr-McGee’s health and safety practices‚ began collecting and recording

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

Man‚" the bomb dropped on Nagasaki‚ was a plutonium bomb. Nuclear fission is when two atoms split. The splitting of certain atoms like uranium and plutonium can cause build up of energy. When enough energy is built up with a chain reaction of nuclear fission‚ you can get enough energy to build an atomic bomb. This is how fission bombs‚ like "Little Boy‚" are made. Implosion is when something collapses inward. "Fat Man" was an implosion bomb made with plutonium. Implosion bombs are made differently from

The vehicle’s time displacement is powered by plutonium‚ which supplies 1.21 gigawatts of power to a device Doc calls the “flux capacitor” Doc explains that the car travels to a pre-set date upon reaching 88 miles per hour; as an example to Marty‚ Doc enters the date November 5‚ 1955 the date he came up with the concept of the flux capacitor. Before Doc can make his first trip‚ Libyan terrorists‚ from whom he stole the plutonium‚ arrive and shoot him. Marty attempts to escape using the

hollow sphere of a fissile isotope‚ usually Plutonium-238‚ that is compressed by conventional explosives. The instant compression of the fissile isotope makes it extremely dense for a split-second‚ which causes critical mass. The only two fissile isotopes that are able to be fissioned with the fissioned element rereleasing two or more neutrons are Uranium-235 and Plutonium-238. Uranium has the atomic number 92 and‚ therefore‚ has 92 protons. Plutonium has the atomic number 94‚ having 94 protons

to try to build one before they did. It would change history. Although he did warn them‚ he was denied “because the left-leaning political activist was deemed a potential security risk” (“The Manhattan Project”). It took 6 years‚ and a LOT of plutonium‚ but they finally built a working atomic bomb. There were two types at the time. The gun-like bomb worked where‚ when

The soviet espionage stole information that helped soviet scientists speed up the development of their atomic program. In this paper you will learn about the Soviet espionage and the Manhattan project. With that said‚ the Manhattan Project was started from the threat of the Axis Powers having an atomic bomb. Their scientists would be able to make their first bomb after a breakthrough of a Nuclear Chain Reaction. Countries trying to get information for America and the Manhattan project failed and
