Nuclear reactor - Energy Education

A nuclear reactor is a system used to initiate and contain a nuclear chain reaction, and they have many useful applications. These nuclear reactions produce thermal energy through either nuclear fission (in practice) or nuclear fusion (in development).

Nuclear reactor - Simple English Wikipedia, the free ...

A nuclear reactor is a machine that uses fission to generate heat. There are different designs which use different fuels. Most often, uranium-235 or plutonium-239 are the main components of these fuels. Most nuclear reactors are used to make electricity. In nuclear power plants heat from the fission reactions in the reactor changes water into steam. The steam is then used to power electric ...

Belgium faces winter blackouts amid nuclear reactor ...

A forced shutdown of one nuclear reactor in the lead up to winter may be regarded as unfortunate. But the closure of six of the seven reactors responsible for supplying 40% of Belgium's ...

Thorium Power Canada Inc.

Thorium Power Canada Inc. offers a clean, green, safe and cost effective solution to the growing global energy requirements. Nuclear Alternative Through a partnership with DBI, the company's thorium reactor design provides a nuclear alternative to fossil fuel consumption, taking advantage of abundant and widely available thorium deposits.

What is Nuclear Energy?

Nuclear power plants are larger and more complicated than other power plants. Many redundant safety systems are built to keep the plant operating safely. This complexity causes the up-front cost of a nuclear power plant to be much higher than for a comparable coal plant. Once the plant is built, the fuel costs are much less than fossil fuel costs. In general, the older a nuclear plant gets ...

How reactors work - Canadian Nuclear Association

Because nuclear fission is a very efficient source of energy, nuclear reactors require very little fuel. A single 20-gram uranium fuel pellet can produce the same amount of energy as 400 kilograms of coal, 410 litres of oil, or 350 cubic metres of natural gas.

Nuclear reactor - Liquid-metal reactors | Britannica.com

Liquid-metal reactors. Sodium-cooled fast-neutron-spectrum liquid-metal reactors (LMRs) received much attention during the 1960s and '70s when it appeared that their breeding capabilities would soon be needed to supply fissile material to a rapidly expanding nuclear industry.

Is Nuclear Energy Renewable Energy? - Robert B. Laughlin

Another major argument proposed by the opponents of including nuclear energy as renewable energy is the harmful nuclear waste from nuclear power reactors. The nuclear waste is considered as a radioactive pollutant that goes against the notion of a renewable energy source. [1] Yucca Mountain is one of the examples used quite often to prove this point. Most of the opponents in the US also point ...

Image Credit: Transatomic Science. Conventional Nuclear Reactors are most commonly industrialized as light-water Reactors, which are the most common type of Thermal Reactors.

What is the neutron source in a nuclear reactor? - Quora

I can give you two answers to the question because nuclear reactors use neutron sources as well as produce their own neutrons. Before a nuclear reactor starts up the neutron flux from the fuel is low and the detectors that monitor the flux level may not produce enough signal to be distinguished from noise.

How a Nuclear Reactor Works - Nuclear Energy Institute

The nuclear reactors currently operating in the United States are either boiling water reactors or pressurized water reactors. The names can be a bit misleading: Both use steam to power a generator, but the difference is how they create it.

The Nuclear Energy Division is the unit within the Energy Sector that develops and implements Canadian government policy on nuclear energy. It provides advice on energy policy, as well as institutional, legislative and financial frameworks for the nuclear industry in Canada. It also works closely with the Uranium and Radioactive Waste Division

Our Energy Sources, Nuclear — The National Academies

Another nuclear energy source, fusion, is the process that powers the Sun and the stars. In theory, it could offer a virtually unlimited supply of energy with significantly reduced quantities of long-lived radioactive waste compared to fission, if successfully harnessed in a reactor. To date, several large new research facilities have been built to investigate alternative technologies for ...
