The atomic masses are all different because the number of neutrons in the atoms nuclei vary. Take uranium for example, it has 92 protons, but some atoms of uranium have 146 neutrons, while others have 143 neutrons. The atoms with the same element that have different atomic masses are called isotopes. Most of the atoms of uranium contain 146 neutrons and have a mass of 238 amu. This form of uranium is commonly called U-238. Another form called U-235 has an atomic mass of 235. Both U-238 and U-235 are isotopes of uranium.
Just as there are different approaches to designing cars, and clothes, engineers develop new ways to make different types of nuclear power plants. There are two different types of nuclear power plants in the United States and they are boiling-water reactors (BWR's), and pressurized-water reactors (PWR's). For BWR's, the water heated by the reactor is core turns directly into steam in the reactor vessel and is then used to power the turbine-generator. In a PWR, the water passing through the reactor core is kept under pressure so that it does not turn to steam at all, but remains liquid. The steam that drives the turbine is generated in a separate piece of equipment called a steam generator. A steam generator is a giant cylinder with thousands of tubes in it through which the hot radioactive water can flow. In the steam generator, the outside tubes boil non-radioactive water and it eventually turns into steam. The clean water may come from one of many sources such as oceans, lakes or rivers. The radioactive water flows back to the reactor core, where its reheated, only to flow back to the steam generator. Roughly seventy percent of the reactors operating in the U.S. are PWR.
Nuclear reactors are basically machines that contain and control chain reactions, while releasing heat at a controlled rate. The reactors supply the heat to turn water into steam in electric power plants, which drive the turbine-generators.
A possible solution to this problem is through nuclear energy. ... Through nuclear energy breads many positives as well as negatives. ... Nuclear energy is the energy released by a nuclear reaction, either through fission or fusion. ... Nuclear power is one the safest methods of producing energy. ... The last negative affect of nuclear energy is waste disposal. ...
The image of nuclear energy as an unsafe technology still persists. ... In conclution, Nuclear energy should be used in Saint Lucie County over any other source of energy availible to you. A nuclear power plant produces far more amounts of energy than any other source of energy by far. ... Contrary to popular belief, nuclear plants are safe and enviromentally safe, unlike many other energy sources. ... Nuclear energy is safe, reliable, strong, efficient, and profitable!...
Today, we Americans get more electricity from nuclear energy than from any other source, except coal. In many states, nuclear energy is the leading source of electricity. ... Over 95 percent of our new electric supply since 1973 came from nuclear energy and coal. ... The good news is nuclear energy. ... Other nations have also discovered the environmental benefits of nuclear energy. ...
What is nuclear Power? Nuclear energy was first used in 1956. ... Nuclear fission is the process in which atoms are split and energy is released. ... This nuclear energy can be used to boil water, and give off steam. ... Some advantages of nuclear energy are; that it provides adequate heat, it efficiently produces large amounts of electricity (about 1000MW of electricity per day.) ...
Nuclear Energy During the early stages of nuclear power there were many accidents that resulted in several people's deaths and the destruction of millions of dollars of property. ... Also, the waste that comes from the production of nuclear energy is not suitable for making weapons. ... However, the total cost of nuclear energy is actually less than other sources of power. ... The energy invested in building a plant is paid back in five months (McCarthy).The basic fact about nuclear energy is that the input energy is 4.8 percent of the output energy? ... Nuclear fusion could supply coun...

One problem with nuclear energy is the radioactive waste. ... Nuclear energy is a quick and easy way to get electricity. ... I support the use of nuclear energy for the production of electricity because it is safe and anti-supporters have falsely shown the use of nuclear energy. ... Using nuclear energy properly can be safer than riding in a car. ... I persuade you to support the idea of nuclear energy. ...
Nuclear power, though, is a way that we can produce energy in our own country and we would have control. ... We've only gone upwards in the ways of using nuclear energy and will continue to progress everyday. Another argument in the question of whether we should still resort to nuclear energy is "Where will we put the nuclear waste?" ... By harnessing nuclear energy, we can power our entire world. ... By using nuclear energy, we would also not have to rely on foreign countries deciding how much we pay for this great necessity. ...
