Chapter 1 Overview of past accidents and AP1000 plant design objectives No doubt, nuclear reactors generate power all due to nuclear fission. A nuclear fission is a typical decay in which an atom splits into smaller parts and emits a considerably large amount of energy throughout the reaction. Typically, there are three types of nuclear reactor that are commonly used throughout the globe. They are the Pressurized Heavy Water Reactor (PHWR), Boiling Water Reactor (BWR) and Pressurized Water…

element, an unstable element has a certain number of protons and neutrons that make up the nucleus. If an element is stable, there will be a proportionate amount of neutrons to protons, however, when it comes to unstable elements there is a disproportionate amount of neutrons to protons. As Iodine-131 is radioactive, when it breaks down a new element is created, Xenon-131. This occurs because Iodine-131 is unstable which then causes the neutrons to change into either protons and electrons,…

Xram's societies views are quite powerful in shaping their views about life around them. Their societies views are far different when you compare it to our society. Furthermore, their society has a different outlook on their world. Overall, there are a lot of things we can say about Xram's society based on their view about us. An interesting thing that Xram's society noticed on earth, was that there was a slight trace of radioactivity in the earth's atmosphere. They did that by applying…

The atomic radius will slowly decrease as you move across a period on the periodic table; this is caused by the addition of protons found in the nuclei of the elements. For every new proton being added, several electrons will also be included into this process by joining the identical energy level (ultimately accounting for one electron per element in said period). The electrons then attract the protons, whilst failing to shield from or repulse this attraction. Given the above information, the…

Covalent bonding occurs when atoms share pairs of electrons. Atoms will covalently bond with other atoms in order to gain more stability, which are gained by forming a full electron shell. By sharing their outer most valence electrons, atoms can fill up their outer electron shell and gain stability (Chem wiki) Nonmetals will readily form covalent bonds with other nonmetals in order to obtain stability, and can form anywhere between one to three covalent bonds with other nonmetals depending on…

Chemistry As Carl Sagan once said, “Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together, they make a placid and non-poisonous substance, table salt. Why each of these substances has the properties it does is a subject called chemistry.” Chemistry involves many things, from atoms to elements and their functions. It is a wide field of science with an extensive early and modern history. It also…

One of the main experiments Rutherford is known for is his Gold foil experiment. He devised a way to prove that radioactivity in particles exists in at least two forms. In the experiment tiny alpha particles were shot at a sheet of foil coated in ZnS which resulted in a small percentage went through the sheet and the rest were blocked/deflected. The percentage of particles that were able to go through the foil are now named 'Alpha Particles' and the ones that were blocked are called 'Beta…

things that make each element have a distinguished quality, is that they have different types of atoms. Atoms are the basic building blocks of matter, and cannot be broken down to a further point. Each atom is made up of protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, while the electrons stay far apart from each other, and revolve around the center. This is called the Bohr model, made by Neil Bohr in 1913. Neil Bohr was born on October 7th 1885. His father…

element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons. The electron configuration of Strontium is 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10) 4s^(2) 4p^(6) 5s^(2) or [Kr] 5s^(2). Strontium has an mass number of 87. Strontium can be a naturally element that can be found in…

A gray cloud rolls off the edge of the stage, fizzling out as it spills into the crowded hall. The audience gasps in surprise and on-stage, Nobel Laureate Bill Phillips smiles as he continues to pour liquid nitrogen across the floor. Phillips, recipient of the Nobel prize in Physics in 1997 for his work cooling atoms with laser light and a member of the National Institute of Standards and Technology, stands in Bethel’s Benson Great Hall before a captivated audience. Phillips has worked as an…
