Nuclear Technology Is The Reaction Of An Atomic Nuclei

Albert Einstein developed an equation for this process, E=mc^2. To summarize this equation, energy is lost or produced when a change in mass occurs. So the process of nuclear fission begins with a neutron. The neutron then strikes the Uranium nucleus, causing the Uranium nucleus to split into two Uranium nuclei. By splitting the nucleus, it also produces more neutrons, and with those neutron, it continues to split the Uranium nucleus. From this uncontrolled process of fission, nuclear weapons can be made. This process is known as a nuclear chain reaction. The energy released (exothermic reaction) from this chain reaction is what powered the atomic bombs.

Nuclear weapons provide a great and purposeful value clearly worth the time and money spent on them in the 1940’s. The research in nuclear weapons has lead to many discoveries and ideas that still influence the world today. These ideas have led to the

On August 6, 1945 a U.S plane dropped an atomic bomb on a city in Japan called Hiroshima. It killed 30,000 people in seconds. The Little Boy killed at least killed 80,000 and 140,000 were injured. This weapon made of plutonium was the first nuclear weapon

One of the most rememberable nuclear bombings done by the United States, these bombs were used on Hiroshima and Nagasaki in retaliation of Pearl Harbor (Kroenig). Even though nukes were used a little, fission bombs were the main type of bombs that the Ally bombers would use on their bombing raids. (Kroenig). These fission bombs had a big blast radius, which led to more destruction (Kroenig). Without these kind of bombs, bomber planes wouldn’t have been as effective as they were.

The atom bomb is a bomb that derives its destructive power from the rapid release of nuclear energy by fission of heavy atomic nuclei, causing damage through heat, blast, and radioactivity. To create this weapon of mass destruction the government started the Manhattan Project and the main mastermind behind this project was Robert Oppenheimer. The project lasted from 1942 to 1946 and its goal was to create the first nuclear weapons for World War II. On August 6, 1945, the American bomber Enola Gay dropped an atomic bomb over the Japanese city of Hiroshima and killed 80,000 people. On August 9, 1945, another bomb was dropped on the city of Nagasaki, killing 40,000 more people. Then a few days later, Japan announced its surrender from World War II. In the article “Thank God for the Atom Bomb” by Paul Fussell he explains how the atom bomb needed to be dropped to save soldiers lives and to end the war.

The first bomb dropped in World War II was the Little Boy. The Little Boy bomb was a gun-type device, whose critical mass was achieved when a uranium projectile was fired into a uranium target through a barrel. Both were in a subcritical state. The resulting uranium mass was composed of both the projectile and the target going from a subcritical state to a critical state which, in turn, caused the chain reaction to begin. The Little Boy bomb weighed nine thousand seven hundred pounds with a length of ten feet and a diameter of twenty-eight inches. The fuel used for the bomb was made up of highly enriched uranium. The fuel was approximately one hundred forty pounds. The target case, barrel, uranium projectile, and the other main parts of the Little Boy bomb were transported to Tinian Island via the USS Indianapolis. The efficiency of this bomb was destitute. Roughly 1.38% of the uranium fuel had actually fissioned in the bomb. The explosive force of the Little Boy was equal to that of fifteen thousand tons of TNT. The use of the Little Boy bomb was to be dropped on the Japanese city of Hiroshima on August 6, 1945. The delivery of the bomb was by the B-29 Enola Gay which was piloted by Colonel Paul Tibbets (“The Little Boy and Fat

Even though the Little Boy bomb kill tens of thousands of people and devastated the entire city of Hiroshima, it failed to get Japan to surrender. However the U.S was ready to drop their second, more efficient and complex, atom bomb on Kokura. The Fat Man nuclear bomb was an implosion-type weapon consisting of a sphere of U-235 to act as a tamper and had a subcritical plutonium-239 core that was was surrounded by high explosives. To activate the chain reaction to trigger the bomb, the explosives surrounding the fissile material are ignited, which then creates a shock wave which causes the core to rapidly compress. The core density then increases, the mass becomes critical, then supercritical. The initiator is shortly released producing many

What is an atomic bomb? Well, an atomic bomb is a bomb that derives its destructive power from a rapid release of nuclear energy by fission of heavy atomic nuclei, causing damage through heat, blast, and radioactivity. In 1938, German scientists Otto Hahn and his assistant Fritz Strassmann discovered nuclear fission. (iaea.org) Nuclear fission is when “the

The nuclear weapons were first introduced and used during World War II. They were totally ahead of their time. No one would have ever thought of such destructive weapons. The atomic bomb or the nuclear bomb was invented and is credited to the scientist Albert Einstein. Einstein was a German Jew that escaped Germany and came to the United States. He was a crazy and very intellectual scientist. He was the key for the existence of nuclear weapons. Before the atomic bombs were actually tested against the Japanese, the United States tested a bomb right in the New Mexico desert area. The Manhattan Project was a project to come up with a new weapon and test it to end the war. Then later on after being proved effective and approved, it was used against the Japanese to end the war. Two atomic bombs were created “Little Boy” and Fatman”. Little Boy was the codename for the type of atomic bomb dropped on the Japanese city of Hiroshima on 6 August 1945. Little Boy was filled with Uranium, weighed 9,700 pounds and 10 feet in length. It was the first time nuclear bomb used and the first one of the war. While Fatman was dropped on the Japanese city of Nagasaki on August 9, 1945. It was the second nuclear weapon used in war and was filled with highly enriched Plutonium, weighed 10,800 pounds, and was 11 feet

Eager to end WWII the atomic bomb was created to end the fight between Japan and the United States. The U.S. dropped it on the cities Hiroshima and Nagasaki. The atomic bomb was created with uranium (U-235) and by using fission it would form a large nuclear chain reaction that would be devastating. The creation of this mass destruction weapon was called the Manhattan Project. The project cost around two billion dollars. In mid-July, 1945, these bombs were tested to see if they would be successful at halting Japan. On August 6, 1945 a day in history and a day that will never be forgotten the U.S. dropped the atomic bomb “Little Boy” on Hiroshima in Japan. Three days later the second bomb dropped called “Fat Man” on the city of Nagasaki. The

The research for a weapon which could end the world’s most devastating war World War II started almost immediately after the attack on Pearl Harbor. Pearl Harbor got sneak attacked by Japan which entered the United States to the allied side of World War II. In 1938 some german scientists discovered that if you bombard Uranium with neutrons you could split the Nucleus of an atom. When the war started scientists thought about military uses of this new discovery. When the atoms split it releases energy and if you put billions of these atoms together it could start a chain reaction and make a massive explosion. Three physicists leo Szilard, Eugene Wigner, and Edward Teller, believed that a

[1]The Manhattan Project was a research and development project that produced the first nuclear weapon of mass destruction during World War II. It was conducted by the United States, the United Kingdom, and Canada. [4][2]During this time, two types of bombs were developed. A gun-type fission weapon was made of uranium-235 which is an isotope that only makes up 0.7% of natural uranium. Although it is chemically identical to uranium-238 it was difficult to separate it. Three methods were used for uranium enrichment: electromagnetic, gaseous, and thermal most of which was done at Oak Ridge, TN and Hanford, WA. [6]The uranium was irradiated. Then it was transmuted into plutonium. [3]Chemically, it was separated and made into uranium. [5]Since the

The first Atomic Bomb the U.S. Americans dropped was in war 11 they name for the atomic bomb was called little boy the little boy atomic bomb was a gun-type weapon with a uranium core in the back of the bomb then close to the uranium core was a Hollow uranium bullet with is a bullet in the back on the bomb and then in the middle of the bomb is a Gun barrel which is a tube where the bullet travels when the gun bullet fires and then at the very top of the atomic bomb inside is a cylinder target witch is a target that enables you to detect and track images rolled into the cylinder it also can identify the side length and diameters of the cylinder target and adding the images that you want to detect. And then once the atomic bomb hits any object the bomb explodes witch means that the Gun barrel traveled through the bomb and that the uranium bullet has already exploded so that

One nuclear weapon, nuclear reaction is the use of light and heat radiation, blast and radiation induced effects on killing and destruction, as well as causing widespread radioactive contamination, to prevent the other

Atomic bombs are made up of uranium, that has an isotope that creates a nuclear chain reaction. The immediate energy release per atom is about 180 million electron volts. It is caused by a sudden release of energy produced by splitting the nuclei of the fissile elements making up the bombs' core.
