ABSTRACT
The demand of energy is growing, causing the energy crisis to worsen. A new source of
energy must be found before fossil fuels run out. Nuclear fusion is a possible way of producing
electricity. The D-T and D-3He reactions can produce enough energy to last thousands of years
because there is a virtually limitless amount of deuterium on Earth, and tritium and helium-3 can
be made from deuterium. Therefore, nuclear fusion is a promising environment-friendly source
of energy.

INTRODUCTION
Our growing need of energy has always been a problem. As the population grew and
cities expanded, the demand for energy increased. Primarily, wind and running water were used
as a source of energy to run factories during the Industrial Revolution. Before long, we started
producing and using electricity to do work by burning fossil fuels and using solar, water, wind,
and other forms of energy. When Albert Einstein found the relationship between mass and
energy, nuclear fission was studied and developed. Now, we use various types of energy,
including chemical energy, nuclear energy, kinetic energy, and solar energy. From these
sources, we make huge amounts of electricity, totaling almost four billion megawatt-hours in the
United States.
Although we have many ways of producing energy, some sources of energy are now
declining. Fossil fuels will soon be used up, and nuclear fission will not last, as the isotopes of
uranium and plutonium that are used in fission are very scarce. Fossil fuels and nuclear energy
yield well over half of the electricity produced in the nation, but these two sources cause
pollution and create radioactive materials. When fossil fuels are gone, a new way to produce
electricity must be developed. ...

...actors. Some fusion reactions result in radioactive neutrons that bombard the walls of
the reactors so they must be frequently replaced. If certain materials can withstand the shower of
so many flying neutrons as well as the high heat of the plasma, then those materials could be
used as permanent walls of reactors, lowering the maintenance costs of a fusion reactor.

Essay Nuclear Power And Nuclear Energy

- Nuclear Energy in Japan Did you know only 70 miles away from Japan’s capital city Tokyo lived a “Nuclear Valley”, encompassing more than 15 nuclear power plants. This valley was bound for success and energy delivery, until in 1999 everything went south. The Tokaimura incident is one of many nuclear catastrophes in Japan making citizens unhappy [Cont. Japan]. What is Japan’s current situation in relation to nuclear energy today. The late 1990’s was a boom in Japan’s electrical output with the help of the very first Nuclear Power plant built in the Tokai area the power plant generated up to 27.7 Billion Kilowatt hours of energy in its 2 years of up-time [ inis.iaea.org]....   [tags: Nuclear power, Nuclear fission, Nuclear fusion]

The Problem Of Nuclear Power Essay

- In terms of the world 's emission problem I believe Peter Thiel said it best,”We can keep on merely talking about a carbon-free world, or we can go ahead and create one”. We have had the solution for over 50 years, so why are we sitting around speaking of solutions that have failed to come to fruition. Where are the people getting their misinformation on nuclear power. Solar panels and huge windmills can’t produce enough power to be considered a serious alternative. It seems that people who believe solar and wind power to be the answer are seriously misinformed about how ineffective those methods are and just how effective nuclear power is....   [tags: Nuclear power, Coal, Fusion power, Carbon dioxide]

Essay about The Problem Of Nuclear Power

- In terms of the world 's emission problem, Peter Thiel (2015) said it best in his article with, ”We can keep on merely talking about a carbon-free world, or we can go ahead and create one” (Thiel 6). We have had the solution for over 50 years, so why are we sitting around speaking of solutions that have failed to come to fruition. Where are the people getting their misinformation on nuclear power. Solar panels and huge windmills can’t produce enough power to be considered a serious alternative.

The Obstacles Of Nuclear Power Essay

- The Obstacles to Nuclear Power The United States relies on nuclear power to generate a significant portion of the electricity needed in our homes and businesses. As nuclear power plants, as well as the nuclear work force, ages, companies will be faced with difficult decisions regarding weather or not to construct new nuclear power plants. My research question focuses on the obstacles to nuclear power growth as an industry. What are the economic, political, and social problems that have driven the United States away from nuclear power, and what can be done to eliminate them....   [tags: Nuclear power, Nuclear fission, Fusion power]

Advantages of Nuclear Fusion for Energy Essay

- Nuclear energy is an alternative to using fossil fuels. Although nuclear energy is also nonrenewable, it has a much lower amount of air pollution, as well as a lower risk of affecting the climate through global warming. There are three main kinds of nuclear energy, nuclear fusion, nuclear fission, and radioactive decay. This report will explain how nuclear fusion works, as well as explaining the advantages and disadvantages of nuclear fusion. Nuclear fusion occurs when two or more elements are fused together....   [tags: Nuclear energy, ]

Nuclear Fusion Essay

- The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1)....   [tags: physics nuclear fusion]

Nuclear Power And Nuclear Energy Essay

- In 1789, Uranium was discovered by a German chemist. 149 years later in 1939, a German scientist by the name of Otto Hahn along, with his assistant Fritz Strassmann, discovered nuclear fission. Nuclear fission releases massive amounts of energy. But not only does it release massive amounts of energy, Nuclear fission will also release additional neutrons which can then produce fission in other uranium nuclei. Which could then turn into a self sufficient chain reaction which can produce massive amounts of energy....   [tags: Nuclear power, Nuclear fission]

Fusion: Harnessing the Power of the Sun Essay

- History It has been a well-accepted fact that the sun is a source of great power since the early part of this century. In 1929, scientists first theorized that the energy production in stars was created by fusion: nuclear reactions involving light elements reacting to form heavier elements. By the late thirties, H. Bethe had analyzed most of our sun's nuclear fusion cycle. Fusion in our sun is caused when deuterium and tritium, both Hydrogen isotopes, react (in the presence of large amounts of heat) to form Helium, energy, and an extra neutron....   [tags: physics fusion]

Essay on Fusion: The Energy of the Future?

- Fusion: The Energy of the Future.      Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth's sun. But are there any problems with this hopeful energy source. What is Nuclear Fusion.      To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more smaller nuclei by bombarding them with neutrons of low energy....   [tags: Nuclear Fusion]
