Robert Oppenheimer forever changed the world with his work on the Manhattan project during WWII‚ contributing to the Cold War‚ creating a nuclear warfare‚ and showed the potential for nuclear energy. He was the lead scientist of this world-shattering project. The Manhattan Project developed the atomic bombs that were nicknamed “Fat Man” and “Little Boy” that put an end to WWII and forever changed the way the world fights wars. The atomic bombs dropped on Hiroshima and Nagasaki killed 250‚000 people

The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism‚ however he didn’t write about his theories in detail. However‚ Democritus‚ his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that

fusion with heavier nuclei. This is the process that gives rise to nucleosynthesis‚ the creation of the heavy elements during events like supernovas. 4. Nuclear power plant A) Working :- Nuclear power plants are powered by Uranium. In a process known as nuclear fission‚ uranium atoms are split to produce large amount of energy which is eventually converted to heat. The enormous amount of heat created‚ boils the water to produce steam‚ which is used to rotate turbines. These turbines in-turn spin the

Nuclear reaction is controlled by regulating the number of neutrons that are created. Control rods absorb neutrons are inserted between the uranium fuel rods. They are increased or reduced in order to keep a constant release of energy. Strong nuclear forces are involved together with the weak interaction. Nuclear energy starts off from the splitting of uranium atoms in a process called fission. At the power plant‚ the fission process is used to produce heat for creating steam‚ which is used by a turbine

Due to an expiring contract with a power supplier‚ the production of Uranium fuel became very expensive at the current Paducah plant. USEC created a new plant called APC in an attempt to advance technology and become the low cost producers in the Uranium industry. Mackovjak is a financial analyst tasked with the evaluation of USEC.

Marie Curie How were the elements of the periodic table discovered? Who discovered them? These are questions that some people may ask. Marie Curie and her husband‚ Pierre Curie‚ were two scientists that discovered two elements of the periodic table‚ polonium and radium. She and her husband worked all of their lives to understand radium and radioactivity. When something is radioactive‚ it produces radiation‚ which is moving subatomic particles.The interesting thing is‚ that radium‚ what Marie Curie

The scope of the essay was focused on four main points: how long reserves of Thorium would last‚ the benefits of reduced pollution using Thorium reactors‚ Thorium’s inability to be used in weapons‚ and its advantage over the current nuclear fuel Uranium. Most sources were found in a database called EBSCOhost‚ in which there was a concept for a reactor known as the Radkowsky design‚ two articles‚ one focusing on the benefits of Thorium by V.B.

reaction? In nuclear fission‚ atoms of uranium-235(any unstable nucleus with a sufficiently high number of nuclear mass) are bombarded with neutrons. Ordinarily neutrons move too quickly to split nuclei when they collide with them‚ but if neutrons are slowed down they can break apart nuclei. Each collision splits uranium atoms into smaller atoms and releases two or three neutrons‚ along with energy and radiation. Because the uranium nuclei is surrounded by innumerous number of other similar
