The Origin  In Chicago in 1942 scientists gathered in front of a clicking clocklike dial the source of the humming was coming from a pile of metal bricks that is now referred to by scientists as “the pile.”  Uranium was discovered in 1789 by Martin Klaeroth, a German chemist.  The element was named after the planet Uranus.  Radiation was discovered by Wilhelm Rontgen in 1895 by passing electric current through a glass tube producing x-rays.  In 1896 Henry Becquerel found that pitchblende, an ore containing radium, and uranium which caused a photographic plate to darken.  In the same year (1896) Pierre and Marie Wrie gave the name radioactivity to this nature.  In 1898, Samuel Prescott showed that radiation destroys bacteria in food.  In 1902 Ernest Rutherford showed that radioactivity as an event for emitting alpha or particles from the nuclei created a different element.

The Finding of Nuclear of Energy  Nuclear power can come from the fission of uranium, platinum, or the fission of hydrogen into helium.  You can find nuclear energy in uranium  Its also found in Kazakhastan in Canada and Australia,  Those are the 3 producers of uranium.  Uranium can be found in uranium mines.

The use of Nuclear Power  Generating homes  Generating buildings  Starting heating systems  Generating stadiums  Be used as an energy source  Uranium is abundant  The amount of waste produced is the least of any major energy production process.  Provides benefits other than electricity generation.

Equipment  To protect themselves from radiators workers wear protective suites to shield themselves from radiation.  Scientists wear safe protective clothing to measure the level of radioactivity in surrounding areas.  Nuclear energy workers wear special suites and respirators that become contaminated with low levels of radiation.  Workers wear suites to protect themselves from radiation they wear gasmasks and long suites with gloves.  The carry around an electrometer, a film badge, dose meter they wear special coveralls.

Nuclear Power Plant

Pros and Cons Pros and Cons  Produces immense power from tiny amounts of fuel.  Nuclear fuels will last far longer than fossil fuels such as coal, oil, and natural gas burned in other power power plants.  Nuclear power plants produce “clean” energy that adds little to air and water pollution.  Fossil-fuel burning plants produce much pollution including acid rain.  Nuclear energy workers wear special suits and respirators that become contaminated with low levels of radiation.  For every kilogram of nuclear energy produced, it is the same as using 1,000 pounds of coal. Nuclear waste gives off dangerous radiation force much over 1,000 years. Safely storing the waste is a HUGE problem. All of the nuclear waste made in the United States over the last 40 years could cover a football field,15 feet deep. Nuclear energy has several huge drawbacks. “ High-level” waste that emits strong radioactivity remains dangerous for hundreds- even thousands-of years. No nuclear waste storage area is completely safe for workers. Also the waste sites must be securely guarded to prevent intruders. Finally, as current storage areas fill up, we will need to build new, safe sites for future nuclear wastes.

How Nuclear Power is Used to Make Steam

 No nuclear waste storage area is completely safe for workers.  Also, the waste sights must be securely guarded to prevent intruders.  Some nuclear wastes are stored in caves or tunnels deep under the ocean bed. Earthquakes could crack the rocks and leak radioactivity.  Also, the waste could be set in water for a few years then mixed in with liquid glass, poured into a steel container and then set in a cement building until the radio activity wears off, which can take tens of thousands of years.  There is at least 3,530 cubic feet of radioactive waste each year.

Atomic Bomb

Fun Facts!  Nuclear energy is released either by splitting atomic nuclei or by forcing the nuclei of atoms together.  Nuclear energy comes from mass-to-energy conversions that occur in the splitting of the atoms.  Nuclear energy is produced by a controlled nuclear chain reaction and creates heat-which is used to boil water, produce steam, and drive a steam turbine.  Nuclear power plants need less fuel than ones which burn fossil fuels.  In France, nuclear power is the most widespread, supplying 80 percent of the country’s electricity.

Fun Facts Part:2  The basic fuel and reactors and Uranium.  Only a couple prototypes of a fast reactor has been built so far, one in Scotland, two in the United States, and one in France.  A fast reactor is a reaction that makes more fuel than it consumes.  To turn a fast reactor on and off, control rods are used for a material that absorbs neutrons, when they soak up many neutrons the reactor stops. When they absorb fewer neutrons the reactor speeds up.
