Nuclear Power Assignment -Containment structure: This is usually a big concrete dome or structure that protects workers and the area around it from potentially dangerous radiation. The walls of the structure are metres thick of concrete to absorb the radiation. -Reactor: The reactor is the most important part of the process as it produces heat which forms steam to power the turbines therefore creating electricity. It uses uranium-235 or in some cases plutonium-239. -Control rods: Control

- Energy is lost to friction - Energy is transformed into electrical energy 8.4.5: Role of moderator: The moderator (or neutron moderator) is a material or medium usually made out of light water (H2O)‚ heavy water (D2O)‚ beryllium‚ or solid graphite‚ which lowers the kinetic energy of fast neutrons by reducing its speed converting it into thermal neutrons. Fast neutrons with energy of about 1 MeV (or speed of about 107 ms-1) are highly unlikely to cause further fissions‚ due to their low cross

6.1.1 If the reaction produces heat (increases the temperature of the surroundings) then it’s exothermic. If it decreases the temp (i.e. absorbs heat) then it’s endothermic. Also‚ the yield of an equilibrium reaction which is exothermic will be increased if it occurs at low temps‚ and so for endothermic reactions at high temperatures. 6.1.2 Exothermic : A reaction which produces heat. Endothermic : A reaction which absorbs heat. Enthalpy of reaction : The change in internal energy (H) through

Paul Klee Paul Klee was born on the 18th of December 1879‚ and died on the 29th of June 1940. He was considered as a talented Swiss and German painter.The artwork created by Klee had dramatically changed over his years of developing his paintings. The timeline below demonstrates the changes over his working years of creating abstract art. In the Style of Kairouan: ‘In the Style of Kairouan’ shows Klee’s first pure abstract painting‚ created in 1914. Klee used a simple combination of coloured shapes

they give the illusion that they could be to be the ones casting the shadows that are in the work. The work is larger than most of those around it. This painting is hung in a thin silver frame. The frame seems to have two parts‚ the inner part is a graphite color and looks as if it could be slate. The next part is the silver part that was mentioned before‚ this part lays over part of the first part creating a layered affect (Evansville

Alex Montalbano Vincent van Gogh 1 In the painting Starry Night by Vincent van Gogh‚ you see two prominent swirls in the background in the sky. One swirl flows into the second‚ smaller swirl. Both light blue swirls are flowing to the right through a dark blue night sky. In the upper right hand corner is a yellow-orange crescent moon surrounded by a yellow glow. Also in the background are eleven variously sized yellow-orange stars scattered amongst the blue sky. At the bottom of the background‚ right

Applied Corporate Finance Case: American Chemical Corporation The primary issue we are exploring here is the planned sale of the Collinsville Plant by American Chemical Corporation to Dixon at a negotiated price of $ 12 Million (as of end of year ‘79) Q1: Estimate the appropriate cost of capital for the investment To calculate the appropriate cost of capital we assessed Dixon’s purchase investment structure. The steps were as follows: 1. We first calculated the cost of debt of the investment using

Plutonium Essay I would like to work on the metal plutonium because the discovery of plutonium has a great impact on the world. Plutonium’s symbol is Pu and its atomic number is 94. This element has 150 neutrons and 94 protons and its standard atomic weigh is 244. Plutonium is located in the 7th period and it is a silvery white metal. One of its main uses is to act as the fuel of nuclear fission Plutonium does not exist naturally‚ although some say that small
