1 Vaporization 1 About This website was founded as a non-profit project, built entirely by a group of young engineers. Entire website is based on our own personal perspectives, and does not represent any views of any company in the energy industry. Main purpose of this project is to help the public to learn some interesting and important information about the energy and about the nuclear energy. We realize that the basics in the nuclear physics do not belong to fundamental human knowledge and the term nuclear often evokes a feeling of something negative or even dangerous. We do not claim this or that opinion is the only opinion that is right. But it is noteworthy, that the vast majority of nuclear engineers, people who know what nuclear means, do not connect the term nuclear with anything negative or dangerous. Anyone can be able to come here, learn the basics of nuclear and reactor physics and should be able to answer basic questions. The best way to promote nuclear power is to present the facts. Would you like to: learn something new? know how does the nuclear power plant works? know how does the nuclear reactor starts? Follow us, we can answer many of your questions! their Copyright Notice ( 1

4 Vaporization 4 0 REACTORS UNDER CONSTRUCTION PWR Pressurized Water Reactors Pressurized water reactors use a reactor pressure vessel (RPV) to contain the nuclear fuel, moderator, control rods and coolant. They are cooled and moderated by high-pressure liquid water (e.g. 16MPa). At this pressure water boils at approximately 350 C (662 F). PWR 62% BWR their Copyright Notice ( 4

5 Vaporization 5 Boiling Water Reactors A boiling water reactor is cooled and moderated by water like a PWR, but at a lower pressure (7MPa), which allows the water to boil inside the pressure vessel producing the steam that runs the turbines. The BWRs don t have any steam generator. BWR 19% Pros of Nuclear Power World-scale energy source Low pollution energy source Carbon free energy source Nuclear power can be sustainable their Copyright Notice ( 5
