A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), which runs through turbines. These either drive a ship's propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. Some are run only for research. Today there are about 450 nuclear power reactors that are used to generate electricity in about 30 countries around the world.
Just as conventional power-stations generate electricity by harnessing the thermal energy released from burning fossil fuels, nuclear reactors convert the energy released by controlled nuclear fission into thermal energy for further conversion to mechanical or electrical forms.

The Pennsylvania State University (PSU) Radiation Science & Engineering Center (RSEC) houses the Breazeale Nuclear Reactor (BNR). This reactor is the oldest operating in the nation and has undergone numerous power upgrades, renovations, and other changes. The reactor serves the research purposes of the Penn State Department of Mechanical and Nuclear Engineering as well as researchers from industry and other universities. Its total licensed thermal output is 1.1 MW, however the reactor is procedurally limited to 1.0 MW (for 100% operation).
The BNR first went critical on August 15, 1955 making it the oldest operating reactor in the U.S.. Other research reactors predate it but have since been decommissioned such as the first reactor at NC State.
A state university system in the United States is a group of public universities supported by an individual state, or a similar entity such as the District of Columbia. These systems constitute the majority of public-funded universities in the country. Each state supports at least one such system.
State university systems should not be confused with federally funded colleges and universities, at which attendance is limited to military personnel and government employees. Members of foreign militaries and governments also attend some schools. These schools include the United States military academies, Naval Postgraduate School, and military staff colleges.
A state university system normally means a single legal entity and administration, but may consist of several institutions, each with its own identity as a university. Some states—such as California and Texas—support more than one such system.
State universities get subsidies from their states. The amount of the subsidy varies from university to university and state to state, but the effect is to lower tuition costs below that of private universities for students from that state or district. As more and more Americans attend college, and private tuition rates increase well beyond the rate of inflation, admission to state universities is becoming more and more competitive.
The blue light is known as Cherenkov radiation. It is similar to a sonic boom, but instead of an object travelling faster than the speed of sound, a charged particle is travelling faster than the speed of light in a medium. In this case, the speed of light in water is roughly 75% the speed of light in a vacuum. It tests the time-dependent properties of the fuel. Engineers use that data to predict what would happen if there were an accident at a large reactor Cherenkov radiation, also known as Vavilov–Cherenkov radiation,[a] is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to Cherenkov ...

The STATE OF THE ART KESHE REACTOR Worldwide Presentation, Congress Center Fenaroli Palace, Brescia Italy 21 April 2013 - WORLD PEACE TREATY CONFERENCE
The Aerojet General Nucleonics Reactor, known as the AGN - 201, located at Idaho State University is now in its 50th year of operation. Adam Mallicoat, Reactor Supervisor, says that it was designed to be operated by young people, specifically for high school students. "You would go and you would train on the reactor and learn how to operate while you were still in high school. You would graduate and you would go out and start working at a power plant, or a national lab," Mallicoat said. The company that originally designed the reactor, Aerojet General Nucleonics, is out of business, and not producing any replacement parts. If a part breaks it can be upgraded, or rebuilt by a machinist. The AGN 201 Nuclear Reactor is one of only five similar models left in the world. Mallicoat says th...

Nuclear Reactor - Understanding how it works | Physics Elearnin video Nuclear reactors are the modern day devices extensively used for power generation as the traditional fossil fuels, like coal, are at the breach of extinction. A nuclear reactor is the source of intense heat which is in turn used for generation of power in nuclear power station. Its mechanism is similar to that of a furnace in a steam generator; the steam is used to drive the turbines of the electric generator system. A nuclear reactor consists of three crucial components: Fuel elements, moderator and control rods. Fuel elements come usually in the shape of thin rods of about 1cm in diameter and contain fissionable nuclei, like Uranium (235 92U or 238 92U). These rods vary in number according to the size of the react...
Highlights from the Penn State Breazeale Nuclear Reactor history, research, outreach, and teaching from 1955 - 2015.
Pulsing of Nuclear Reactor- The reactor is brought to criticality and then the transient control rod is forced out. This causes a power pulse of about 500-1000 MW. Here is a different pulse we did: http://www.youtube.com/watch?v=jFAH_un1iqg&feature;=g-upl
This is the research reactor on the Washington State University campus pulsing to 1.2GW at different levels of reactivity (in units of dollars). The blue glow is caused by high energy beta particles (or electrons) interacting with the water around the reactor. The reactor is a 1MW TRIGA type and is used for research only (no power is produced). Various isotopes produced and neutron beams are used to aid in research for the chemistry and biological science department, as well as many other research projects on campus. There are only 12 other university reactors of this size left in the US.
Taking the reactor in steady state mode from 0 to 80% and down some... kinda lengthy but good demonstation of cherenkov radiation intensity. Next time I will turn the lights in the room off in addition to the pool. Here is a link to the same reactor pulsing - ejecting rods to go prompt supercritical https://www.youtube.com/watch?v=vkPyGFjVKOA
The Kansas State University TRIGA Mk II Reactor provides services for education, research, and training, and outreach. The reactor is licensed to operate at up to 1250 kWth. For more information visit http://www.mne.ksu.edu/research/centers/reactor/
We apply the Molar Balance Equation to a Continuous Stirred Tank Reactor. This type of reactor has an inlet, outlet a generation but has no accumulation concept This is due to the steady state process (no changes in time) Typical operation of a CSTR is designed for long-time operations See Reactor Engineering Course Playlist: http://goo.gl/6e9iXj Visit the Web-Page for EXTRA content! www.ChemicalEngineeringGuy.com -º--º--º--º--º--º--º--º--º--º--º--º--º--º--º--º--º-- LIKE the video, it helps me to know what you like SHARE the video with your friends!

The pulse is an occasional event, and is usually part of the reactor's annual checkup. Fortunately, thanks to YouTube, you can watch it over and over and over.
Plasma is one of the weirder states of matter but learning to harness it has provided our species with almost all of our best technology. This video first explores what plasma is and how to make it, and then explores how we can use it to make functional devices. Everything from building a high voltage system from scratch, to learning how vacuum systems work is covered and is used to build simple fusion reactors, magnetrons and more. Parts of this video were in the process of being made for over 6 years, so I'm very excited to finally share it with the world. Many of the newer parts were filmed at Scihouse and this video wouldn't have been possible without Scihouse.

Recorded at SpringOne Platform 2016. Speaker: Stéphane Maldini Slides: http://www.slideshare.net/SpringCentral/reactor-30-a-jvm-foundation-for-java-8-and-reactive-streams The apparent simplicity of the publisher/subscriber model as exposed in Reactive-Streams can be deceiving. The relatively fast release cycle for libraries in that space is not a myth, concurrency is hard. To keep out undesired side-effects, most Reactive projects have adopted a vertical approach potentially excluding developers from decision-making around execution model or sometimes language. What if we were able to leave the developer in control, positioning as a robust foundation and making the most of the now industrial standard Java 8 ? What if we hardened this foundation through open-source and research collabora...

Speaker: Stephane Maldini Slides: https://speakerdeck.com/smaldini/introduction-to-reactor-and-reactive-streams What is the role of asynchronous, non-blocking style-communication in microservices? Join Stephane Maldini for a revealing look at why reactive components are so important in an eventually-consistent approach like microservice architecture. When services own their data and are completely independent, having a (reactive) abstraction layer can perform a variety of roles. Being able to parallelize resources a microservice owns is an important technique. Another might be as an event bus, pulling state data from various micro services dynamically, checking against the cached, fairly up-to-date local copy. While a microservice has “all” the data it needs from other services to respond...

http://ThoriumRemix.com/ Thorium is an abundant material which can be transformed into massive quantities of energy. To do so efficiently requires a very different nuclear reactor than the kind we use today- Not one that uses solid fuel rods, but a reactor in which the fuel is kept in a liquid state. Not one that uses pressurized water as a coolant, but a reactor that uses chemically stable molten salts. Such a reactor is called a "Molten Salt Reactor". Many different configurations are possible. Some of these configurations can harness Thorium very efficiently. This video explores the attributes of Molten Salt Reactors. Why are they compelling? And why do many people (including myself) see them as the only economical way of fully harnessing ALL our nuclear fuels... including Thorium. T...
Fusion energy and MIT's pathway for accelerated demonstration with high-magnetic field tokamaks An introduction to the key concepts of producing clean, safe, and carbon-free electricity from magnetic fusion energy. This talk reviews the present state of fusion energy research and then introduce MIT's proposed pathway to use high-field superconducting magnets to achieve fusion energy at smaller unit size, at lower cost, and on a timescale relevant to climate change.
Thorium is an abundant material currently disposed of as waste. It is found in coal ash piles and mine tailings. A single Rare Earths mine could produce enough Thorium byproduct to power the entire planet. To do so requires a very different nuclear reactor than the kinds we use today. Not one that uses solid fuel rods, but a reactor in which the fuel is kept in a liquid state. Not one that uses pressurized water as a coolant, but a reactor that uses extremely stable molten salts. The full description of one such reactor is: 2-Fluid, Thermal-Spectrum, Molten-Salt Breeder Reactor equipped with a chemical fuel salt treatment module. Such a reactor was conceived of decades ago, as documented in the book "Fluid Fuel Reactors" [1958]. Or, simply "LFTR" (Liquid Fluoride Thorium Reactor) as pro...
