Nuclear Energy

Parent Category: Energy
Nuclear energy covers technology of reactors, different types of reactors, their history and development, exploitation in different countries, operating experiences, problems of nuclear waste.
OSHA, NFPA and EPA regulations specify what safety precautions must be taken at power plants. Also various state and local regulations must be considered as well.
If you mean energy produced by nuclear reactors, then "heat" and  "light" would be the answers (Just think of the sun)
uranium is put in a nuclear reactor and the atoms in it are split  apart creating enormous amounts of heat.the heat is then used to  boil water creating steam and turning turbines creating energy  [electricity]
Solar (Light), Wind and Hydro (Water)
No, nuclear power is a decent source of energy, depending upon the  reactor design and siting. Locating reactors over fault lines or  near ocean shore lines seems unwise.
Darlington power station refers to a series of two coal-fired powerstations situated in Darlington in County Durham , North East England .
There are no hazards from nuclear power stations. However, thesestations need careful design, good quality during installation,skillful operators, good maintenance, and application of goodsafety rules during operation and when dealing with nuclear waste.
because with nuclear energy there in no need for fossil fuels, and the only by product is steam. The waste however from nuclear energy plantsdo produce waste uranium, which is hard as hell to get rid off unless u truck it to Nevada to hide in the desert. This technology is amazing and should be used...
In the United states About 20 percent of the total electricity used. In Australia on the other hand none of the power comes from NE.
The challenge of making nuclear power safer doesn't endafter the power has been generated. Nuclear fuel remainsdangerously radioactive for thousands of years after it isno longer useful in a commercial reactor. The resulting waste disposal problem has become a major challengefor...
A nuclear reactor works by using the energy that is releasedwhen the nucleus of a heavy atom splits. That process is calledfission. . In reactors, fission occurs when uranium atoms are hit byslow-moving neutrons. Absorbing these excess neutrons sometimescauses the atoms to break apart. As the...
In nuclear physics, nuclear fusion is a reaction in whichtwo or more atomic nuclei come close ... For example, in the fusionof two hydrogen nuclei to form helium , 0.7% ofthe mass is carried away from the system ... with the release oftwo positrons, two neutrinos (which changes two of...
Rub it off Radioactive polonium brushes available in any photoshop will do this. The alpha particles emitted by the polonium ionize air and the ionized air carries off the static charge. These brushes should be bought new at least every year from a fresh batch at the photoshop due to the short...
Gravitationally confined thermonuclear fusion of hydrogen into helium inside a small volume at the core of the sun, where temperature is so high that the electrons and protons of the hydrogen atoms are completely separate gasses (plasma) and pressure is so high that the density of these gasses is...
Uranium can be reused as nuclear fuel or for other applications. For the most part, Uranium is most useful in it's U-235 form, and also for being converted into P-239 (Plutonium). As natural Uranium is over 99% U-238, various processing methods are used to increase the percentage of U-235 to a level...
the nucleus. it is almost too big to stay together and can get to a lower energy state if it fissions into smaller nuclei. the difference in energy is released as heat.
persons moving energy from sunlight cars moving when you put gasoline in your car helo
More specifically, if their nuclei get "welded together". Otherwise, it is just a chemical reaction. Fusion is the combining of atoms of one element to produce another, with electromagnetic and ionising-particle radiation as by-products depending on what atoms are involved. It's the only way in...
It gets split into elements of lesser atomic number with production  of neutrons
Nuclear fission is nuclear reaction in which nucleus of an atom ,  usually a heavy element, splits into smaller parts i.e. lighter  nuclei . Free neutrons and photons are produced along with release  of large amount of energy.
No. Heavy water refers to water formed with a majority of the heavier isotopes of hydrogen, which are very radioactive; this water can be used to transport such isotopes more easily.Cells use many different chemicals to get their energy, but water is a product of the process, not an "ingredient".
cuz if u heat it particles start to melt.
I found the website K1 Project very helpful. They had several  articles underneath their Learn/Energy tab which should answer any  questions about nuclear fusion.
The first nuclear powered merchant vessel is the NS Savannah. She was built as a feasibility project for the potential use of nuclear energy. Only 4 civilian merchant vessels have ever been built with nuclear plants, and of those, only 1 is still operational, the Russian ship NS Sevmorput. The...
Mainly by the biochemical processes that take place Mainly in the Mitochondria.
It is an approach to reduce size. It must be burned in an isolated furnaces to keep the radioactivity confined. Then the product of incineration is contained in closed barrels (either as such or mixed with cement or asphalt).
At present, the US government is actively promoting nuclear energy. The states, on the other hand, seem to disagree about it.
Involving fission & fusion at the same time? These reactionsare completely different from each other and have no physical ormathematical relationships. I suppose you could claim that ahydrogen bomb that uses a fission trigger is an example of such anequation, however, the fission occurs before the...
Yes, a nuclear reactor produces nuclear radiation. Nuclear reactions in the core produce energy, and they also produce different types of radiation.
Power turbines are driven by steam. Steam can be raised by thermal, nuclear or geothermal processes. Wind and water can also drive a generator.The auxiliaries for a power station (which I think is what this question is asking) are typically powered by step down transformers within the power station....
Mass that is "lost" durning nuclear fusion is converted into binding energy to hold the newly formed atomic nucleus together. The lost mass, which is termed mass deficit, means the nucleus of the newly formed atom has less mass than the sum of the masses of the protons and neutrons that make up that...
No, it is scary, my cousin was harmed by it, thankfully not fatally.
AnswerProbably the nuclear fusion    AnswerThere are a number of reactor designs based on using thorium, and fuel assemblies using thorium as a primary fuel can be designed and built to be used in existing reactors.
The energy comes from the constant fissioning (splitting) of atoms within the nuclear fuel, which is normally uranium or plutonium. The energy is released as heat within the reactor, and boils water for the steam turbines that convert it to electricity.
It takes tremendous heat and pressure to get nuclear fusion to  occur. This heat and pressure is typically available in the cores  of sufficiently massive stars. We have produced fusion reactions on  earth by surrounding hydrogen isotopes with fission bombs. The heat  and pressure cause the gas...
The dangerous condition we know as a meltdown is one wherein the reactor core becomes too hot and fuel rods or plates melt.
The USS George Washington Carver (SSBN-656), (SSN-656), was a Benjamin Franklin-class Ballistic Missile Submarine named after the famed black researcher and inventor. Originally an FBM submarine, it was converted to an Attack Submarine after the START Treaty was ratified. She became a casualty of...
The Sun's fusion takes place in the core. The Convective zone brings heat to the surface by thermal convection, which is basically hot plasma coming up to the surface, then cooling and sinking.
It should isolated from underground water and isolated from  rivers and drinking water. It should be away from expected  earthquake  
because their is to much pollution there
  Nuclear fission does not give off carbon, carbon monoxide or carbon dioxide. The only carbon footprint would come from the vehicles and machinery use to pull the uranium out of the earth.
It is the 3rd isotope of Hydrogen: 1H3 meaning the mass number is 3, and that's why it is called : tri-tium (1 proton and 2 neutrons = 3 mass units) The second isotope is called Deuterium 1H2
The PWR (Pressurised Water Reactor) and the BWR (Boiling Water Reactor) are the only two types use for commercial power operation in the US
Neutrons are the important particles of nuclear chain reactions

The Shippingport reactor was the first full-scale PWR nuclear power plant in the United States.
  splitting a nucleus into two nuclei
Nuclear fission has advanced science in that it has led to the  development of the most powerful weapon ever created, the atomic  bomb. Also, nuclear fission is used in nuclear power plants to  evaporate water to move turbines.
Certain isotopes of some elements can undergo fission. In nature, the only substance that does this is uranium-235, which is less than 1% of all uranium. When U-235 undergoes fission, it makes two much lighter new atoms, and three neutrons. When one of these neutrons hits an atom of U-235, it...

nuclear reactors are not very safe at all. the nuclear energy buisness basically went to crap after the three mile island accident, because people decided the risks outweigh the benefits
The first nuclear reactor was in former Soviet Union that operated  in year 1954 at obninisk.
If we use fossil fuels we can't conserve them, but we should try to use them efficiently, as they can't be replaced and will eventually be used up. Thus drive a 2 litre car instead of a 4 litre or more, 2 litres will take you fast enough. A 6 litre car is just grotesque and totally unnecessary. In...
This question presupposes the existence of an antimatter reactor. As far as I know, no such reactor exists, or has even been designed.Antimatter reacts with matter to produce energy with virtually no matter remaining. Such a reaction is thousands of times more powerful as nuclear reactions we have...
A quarter! After 12.32 years the remainder is one half After another 12.32 years (so 24.64 in total) the remainder is one half of the former half, thus 1/2 * 1/2 = 1/4 Formula:   mto = mt * 2 {t / t(1/2)}   mt = mass on time t (in this calcul 24.6 year) mto=mass on time 0 (begin) t(1/2)=...
fission rate is slowed in nuclear reaction by using neutron control materials that having high neutron absorption capacities (like Cadmium and Boron).
Stellar nucleosynthesis (nuclear fusion) began in our sun about 5  billion years ago. For about a million years prior to nuclear  ignition our sun shined by Helmholtz Contraction, essentially light  and heat emitted from gradual gravitational condensation of gas  collapsing onto the nascent...
Both helium-3 and helium-4 are stable, and neither will spontaneously undergo nuclear change.
Nuclear fission is NOT considered a fossil fuel. Fossils are  artifacts (impressions, trackways, coprolites, or biologic material  replaced through diagenesis) of once living organisms. Coal seams  are the carbon residues of long dead organisms (primarily plants)  compacted typically millions of...
The risks associated with fission reactors have been greatly exaggerated, with funding from other interests in the energy industry.Even if the risks were to be as great as suggested by the coal industry, they are only risks. The damage to forests, and people's lungs, from acid rain is an established...
Maybe Chernobyl, but only for a short time.Ever heard of SL1?Both are sad events.There are some very large coal powered plants in the USA and the rival the nuclear plants.
Humans landed on the moon for the first time on July 20, 1969, during the US NASA Apollo 11 mission commanded by Neil Armstrong. Edwin "Buzz" Aldrin was the pilot of the Lunar Module, and Michael Collins was the pilot of the Command Module, which stayed in lunar orbit.
Physics theory recognises four physical forces, the strong nuclear force, the weak nuclear force, electromagnetic force, and gravity. Clearly in a nucleus with a number of protons, each with a positive charge which would repel each other under electromagnetic forces, there must be something which...
The short answer is, "Not a lot, providing that nothing goes wrong for a time much longer than human history."Nuclear power is a source of carbon dioxide, a global warming gas, as a result of the mining, refining, enriching and transportation of fuel, the construction of the plant, the...
No one knows for sure who invented nuclear energy. The process that led to the production of nuclear energy started in the year 1895 when radiation was ionized. Wilhelm Rontgen passed electric current through an evacuated tube and produced X-rays. In 1896, Pierre and Marie Curie, further tested on...
The main disadvantage is that, as of 2012, it is not technically feasible.
The factors affecting the location of the (nuclear) thermal power stations are partially location in relationship to the grid, and mostly location in relationhip to the heatsink. An enormous amout of energy is generated by the nuclear reaction - in fact the typical efficiency of the nuclear to...
Neutron absorption is the key to the operation of a nuclear reactor as this is what perpetuates the chain reaction. Neutrons can be absorbed by a number of things within the core of an operating reactor, but when a fuel atom absorbs a neutron, it becomes unstable and fissions. The fission event...
Nuclear Power Stations produce electricity by using nuclear energy, without burning coal, gas or oil. Therefore there is minimum effect on the environment, it is a clean supply of energy. One byproduct is hydrogen which can also be used to produce fuel cells to be used in cars. All this will greatly...
Nuclear fission is now commercially available in nuclear fission  reactors since the fifties of last century. Nuclear Fusion is still  under R&D. Nuclear fission reactors are clean energy source.
No.Define "blow up".Power plants have malfunctions that can kill people, unrelated to nuclear fuel.Nuclear elements can be arranged to blow up but you have to get everything exactly right. More danger exists from exposure to the fuel, if it has been activated.
The difficulties involved in producing a sustainable nuclear fusion reaction focus on the enormous temperatures and pressures, energy in other words, required to initiate and maintain the reaction. It is the same as the inverse of Einstein's equation E = MC2 - if the yield of conversion of mass to...
Difficult to know what the questioner is getting at here. South Africa has demonstrated a capability of running a successful nuclear plant with the Koeberg PWR, which was a french design. I believe some operational difficulties occurred due to faults in the HV transmission lines, but this is no...
Much of the heat in the core of the Earth is residual from heat created billions of years back, and some of this was created in fusion reactions in stars.There are other nuclear actions at work in the core of the Earth, however. The more important of these is nuclear decay, which is what most...
I am not precisely sure of what this question means. Nevertheless, we can talk of Ba-138 as an isotope, and hope this covers the subject.Ba-138 is a stable isotope of barium. It has 56 protons and 82 neutrons.There is another isotope of barium which also has 56 protons and 82 neutrons called Ba-138m...
the objects will attract with each other
  The rate of fission in a nuclear reactor is moderated by the insertion of control rods, which absorb some of the neutrons, preventing the reaction from going supercritical and possibly leading to a meltdown. The amount of power being produced, or in other words the intensity of the reaction,...
The most common fusion in the sun is two hydrogen atoms fusing to produce helium. There are different ways this can happen. Two deuterium atoms may fuse, or a deuterium atom may fuse with a tritium atom, or two tritium atoms may fuse. Since the half life of tritium is rather short, the overwhelming...
Hydrogen, and only Hydrogen. Other gasses may be present, but theywould work against the fusion reaction by being in the way andabsorbing energy. In nuclear physics, things that impede thenuclear reactions are called "poisons" and have to be calculated infor their overall effects. As a star ages and...
The answer depends on what you call pollutants. Natural gas, which is rather clean and contributes mostly carbon dioxide to the global warming problem, can be made 65% efficient when a gas turbine is used to generate electricity and waste heat is used to heat buildings. This is about as well as...

On a small scale, electricity is produced by electric batteries. On a larger scale it is produced by electric generators, which can be run by coal power, oil power, natural gas power, wind power, nuclear power, or hydro-electric power; in addition, electricity can be generated on either a small or...
The reaction in a nuclear reactor happens because neutrons hit the nuclei of atoms, which can divide, producing energy, new atoms, and more neutrons.When a neutron hits the nucleus of an atom, four different things can happen. In the case of most collisions with the nuclei of non-radioactive atoms...
