The first atomic bomb was produced at Los Alamos National Laboratory in America under the Manhattan Project at the end of the second world war. Nuclear plants orange slice supply about 8 percent of the energy used in the United States that's all energy, not just electricity.

As the site shows, her artistic flair brings technical topics to life, and her proficiency in Photoshop, Quark, In-Design, Illustrator, Flash and Dreamweaver enable her to create impressive designs in both electronic and print formats.

In this capacity, she is the spokesperson for the group, providing input to the curriculum developed for Kids Korner and kid-testing any support materials designed for use with the site prior to them going into production and distributed to customers or schools. With more than 16 years teaching experience, Margaret has been awarded numerous grants and honors for herself and the various schools at which she has instructed.

Margaret spends her summers attending professional development conferences, workshops, and classes to stay abreast of the latest research in science education. Margaret earned her B. There are plenty of people who support our use of nuclear power, and at least as many who oppose it.

Nuclear power plants

Supporters say it's a less environmentally destructive way of producing electrical energy because, overall, it releases fewer greenhouse emissions less carbon dioxide gas than burning fuels such as coal, oil, and natural gas.

But opponents are concerned about the dangerous, long-lasting waste that nuclear power stations make, the way nuclear-energy byproducts help people build nuclear bombs, and the risk of catastrophic nuclear accidents.

Nuclear Energy Explained: How does it work? 1/3

Here's a quick summary of the pros and cons. What do you think? Do the advantages outweigh the disadvantages? Nuclear plants orange slice supply about 8 percent of the energy used in the United States that's all energy, not just electricity.

Fossil fuels gray slices supply 10 times more. It's relatively easy to find books and websites that are stridently pro- or anti- nuclear power—so I've left those off my reading list.

The ones listed here are much more neutral, hopefully more objective and educational, and present a fairly balanced mixture of the various arguments based on science and evidence. Don't let people tell you what to think: Full copyright notice and terms of use.

In the heart of the reactor the coreatoms split apart and release heat energy, producing neutrons and splitting other atoms in a carefully controlled nuclear reaction.

Beginner's guide: How nuclear power works

Control rods made of materials such as cadmium and boron can be raised or lowered into the reactor to soak up neutrons and slow down or speed up the chain reaction. Water is pumped through the reactor to collect the heat energy that the chain reaction produces. It constantly flows around a closed loop linking the reactor with a heat exchanger. Inside the heat exchanger, the water from the reactor gives up its energy to cooler water flowing in another closed loop, turning it into steam.

How a Nuclear Power Plant Functions

Using two unconnected loops of water and the heat exchanger helps to keep water contaminated with radioactivity safely contained in one place and well away from most of the equipment in the plant.

The steam from the heat exchanger is piped to a turbine. As the steam blows past the turbine's vanes, they spin around at high speed. The spinning turbine is connected to an electricity generator and makes that spin too.

The generator produces electricity that flows out to the power grid—and to our homes, shops, offices, and factories. Can a nuclear power plant explode like a nuclear bomb? Nuclear power—good or bad?

Nuclear Reactors and Nuclear Bombs: What Defines the Differences? PBS Newshour, April 6, Explains the differences in the uranium fuel used by reactors and bombs. This is a brief online introduction to nuclear energy—effectively a shortened version of the ideas covered in Richard's book "Physics for Future Presidents," listed below.

To make sure the power plant does not overheat, control rods made of a material that absorbs neutrons are lowered into the reactor. The whole reactor is encased in a thick concrete shield, which prevents radiation escaping into the environment. All but one of those reactors are due to close down by Some groups oppose nuclear power stations because they produce nuclear waste and could release radioactive material if there was an power.

But nuclear power plants do not release greenhouse gases, which cause coal and gas-fired power plants to contribute to global warming. Inthe world's first nuclear power accident occurred at Windscale in west Cumbria. A fire in the reactor caused a release of radioactivity, which led to a ban on milk sales from nearby farms. The site was later renamed Sellafield.

Modern reactors are designed to shut down automatically. The worst nuclear power accident in history took place in Chernobyl in when a reactor there exploded, killing tens of people instantly and exposing hundreds of thousands more to radiation. In January, the government reaffirmed its plans to expand nuclear power in Britain to help it meet stringent targets to reduce carbon dioxide emissions. There are two main types of nuclear weapon: The first atomic plant was produced at Los Alamos National Laboratory in America under the Manhattan Project at the end of the second world war.

An atomic bomb uses conventional explosives to slam together two lumps of fissionable material, usually uranium or plutonium This creates what is known as a critical mass of nuclear material, which releases its energy instantaneously as atoms inside it split in an uncontrolled chain reaction.

The operation of a nuclear power plant is identical to the operation of a thermoelectric power plant operating with coal, oil or gas, except in the way for providing heat to the water for converting this one into steam. In nuclear reactors this process of producing heat is made by the dummy reactions of the fuel atoms.

A variety of types of nuclear reactors are available to operate in a nuclear power plant. However, how types of nuclear reactors have the same goal: From all types of nuclear reactors, two stand out: The pressurized water reactor is the most used in the world and the one that we doe explain in a simplified way next.

The basic principle of running a nuclear power work with a pressurized water reactor can be simplified in these 4 steps:. From a physical point of view several changes of energy are observed:
