Finally, the nuclear electromagnetic pulse is made of extremely strong magnetic fields. This pulse disturbs the radio contacts and destroys and electronic devices (“The Atom Bomb – the development of the atomic bomb, the uses of the atomic bomb”). So what all happened to Japan when the first two atomic bombs
INTRODUCTION TO NUCLEAR REACTION: The main features of nuclear reactions include radioactive decay, nuclear fission and nuclear fusion. Radioactive decay: Energy is released in a radioactive decay in the form of the kinetic energy of the particle emitted (α and β), the kinetic energy of the daughter nucleus and the energy of the gamma-ray photon that may accompany the decay. The energy involved may be calculated by finding the mass defect of the reaction. The energy released is the energy equivalent of the mass defect of the reaction. Nuclear fission: Nuclear fission is the process in which a large nucleus breaks into two smaller nuclei that are almost equal in mass.
The process of changing one element into another is called transmutation. The two main ways that a transuranic nucleus can be produced is by bombarding its nucleus with ions or neutrons. These ions or neutrons can be captured by the target nucleus and produce heavier nucleus. Transuranic element 1: U-238 is bombarded with neutrons it can be converted to U-239 which then undergoes beta decay to produce neptunium and plutonium. Pu-239 is changed to americium-241 by neutron
The arrangement of particles in an atom Protons and neutrons make up the main, dense, central nucleus in the centre of the atom. This is surrounded by electrons “orbiting” the main nucleus. The electron are in shells depending on their energy levels, as the most energetic are on the outer shells, because they need more energy to travel around a bigger “orbit” of the nucleus. These shells are full when a certain amount of atoms are in the shell; 2 in the first shell, 8 in the next shell, 8 in the third shell and so on. When the shells are full, the atom is unreactive.
Nuclear Power is produced by controlled (non-explosive) reactors. They convert the thermal energy released from nuclear fission. When uranium and plutonium are enriched, it undergoes nuclear fission. It releases kinetic energy and gamma radiation. This whole process is called a nuclear chain reaction.
The atomic bomb killed millions of people in just one bomb , the napalm on the other hand , was nothing like it . An atomic bomb is a nuclear device able to deliver a much larger blast and broader blast effects than conventional weapons. The blast can be thousands or millions of times more devastating than any conventional bomb blast. And in addition to killing in the way chemical explosives do, it can also severely burn and can irradiate victims, and they can die weeks, months or even years after surviving the initial blast. There is also the element of nuclear "residue" from the nuclear blast.
Castle bravo resulted in nuclear fallout which rained down on the islands and service members who were working on the operation. The mushroom cloud grew to 4 ½ miles wide and reached 130,000 feet six minutes after detonation.
By doing this it was creating huge amounts of Energy. Scientists soon realized that they could use this energy to create very powerful bombs. Scientists started working vastly to create an atomic bomb. In this process they found that a rare form of Uranium was needed to create explosive chain reactions. This uranium was Uranium 235.
“Nuclear fission is the process of breaking up atoms; the process will generate an enormous amount of energy in form of heat” (Nuclear Power and the Environment). The first man-made reactor was built in the USA in December 2, 1942 called-
Both these places took the real brunt of the accident and were massively affected. The nuclear plant at Chernobyl was utilizing the RBMK-1000 reactors built in the Soviet Union and it had major design flaws. On the early morning of April 26, 1986 the personals at the plant hastily lowered the super heated nuclear fuel rods into the water that is used for cooling the reactors. This created lots of steam that in turn increased the nuclear reaction particularly in the reactor number 4. This produced an immense amount of energy casing a massive explosion in the reactor.
