Nuclear Chain Reaction Essay

558 words - 3 pages

The scientist Albert Einstein did not participate in the invention of the atomic bomb and nuclear energy. But he was the key to unlocking the development of nuclear energy and atomic bomb. In 1905, as part of his Special Theory of Relativity, he made a point that a large amount of energy could be released from a small amount of matter. This was development of the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly this equation worked. But Einstein wasn’t thinking of nuclear bombs when he thought up E=mc2. A nuclear chain reaction is basically a chain reaction of atoms and neutrons, when they bump they split into more, therefore it gets bigger and bigger with every split. Atoms consist of small dense positively charged ...view middle of the document...

The fission of Uranium splits off two neutrons, which in turn hits two Uranium atoms. Two neutrons are split from each of the two Uranium atoms. Each of these neutrons then go on to hit another Uranium atom. Each of those atoms is split releasing two neutrons, which go on and hit more Uranium atoms. The chain reaction continues on and on, getting bigger and bigger with each split. The things that slow down a chain reaction are the control rods. A control rod is made up of cadmium or boron, which absorb neutrons. If you insert the control rod between the uranium atoms, the amount of neutrons available to cause more splits is reduced. In my project I Arrange the dominoes in a certain pattern. As shown,( ). On another section of the table, I arranged two straight lines of dominos as shown,( ). Then I knocked over the single domino in front on the first pattern. And they fell down like a nuclear chain reaction; the first domino stands for 2 atoms, the 2nd row stands for 2 neutrons split from the 1st atoms or the first domino, so when you hit down the 1st domino it is like a fission of Uranium splitting off into off two neutrons goes on to hit another 2 atoms each of those atoms split releasing two neutrons, which go on and hit more Uranium atoms. It goes on and on if you have millions of dominoes. Then I knocked over the first domino in one of the two straight lines and they all fell. For the second part I took a ruler and held it anywhere between the dominos lined up in the second straight line, then I used my other hand to knock over the first domino. The results were that only some dominos fell because the ruler stopped them from hitting other dominoes. It worked kind of like a control rod used to absorb neutrons in a Nuclear power plant.

The uranium atom subsequently becomes unstable and splits. Heat is released by the nuclear fission reaction which releases more neutrons. The discharged neutrons set off fission reactions of more uranium atoms, which create a chain reaction. (See the fission process illustration below) Each uranium fission

1405 words - 6 pages amount of energy is released along with two or three neutrons. It is these neutrons that can begin a chain reaction, each neutron that is given off could collide with another Uranium atom splitting it apart. Each of these fissioning atoms releases a very large amount of energy, and some more neutrons.This process continues causing a chain reaction withut any outside assistance, and the Uranium has 'gone critical'(Martindale, 794-195). This chain

In conclusion, to not let Iran obtain nuclear weapons only continues to extend Israel’s monopoly in the Middle East as a tyrant; to give in and allow them to develop weapons will inevitably lead to a chain reaction of states wanting to obtain weapons as well. There is clearly no easy way out

A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for generating electricity and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), which runs through turbines Nuclear generated steam

If this process is repeated, a self-sustaining chain reaction will occur, and it is this chain reaction that causes the atomic bomb to have its destructive power (World Book, 1990). This chain reaction can be attained in two different ways. The first type of atomic bomb ever used was a gun-type. In this type two subcritical pieces of U-235 are placed in a device similar to the barrel of an artillery shell. One piece

A nuclear fission device made with Uranium, such as Little Boy, would release the equivalent of 20,000 tons of TNT or 40,000,000 sticks of dynamite. The two radioactive elements that were used in the bombs were Uranium and Plutonium.” (1) The uranium is a radioactive metallic

The team of scientists working on the Manhattan Project immediately realized that one of the largest problems they would have to solve was how to remove uranium-235 from natural uranium, which was composed of 99.3% uranium-238. Two methods were developed during the wartime project, both of which took advantage of the fact that uranium-238 has a slightly greater atomic mass than uranium-235: electromagnetic separation
