How much energy does uranium produce in a certain amount of time?
The energy produced by natural radioactive disintegration is small an important only at geological times scale.
How does electricity generated from nuclear energy?
By Nuclear fission,nucleus of a heavy,radioactive atom (eg-uranium,thorium,plutonium) is bombarded with low-energy neutrons to split into lighter nuclei.This generates tremendous amount of energy.This energy can be used to produce steam which turns the turbine and thus electricity is produced on a large scale. Nuclear energy produces 10 million times the energy produced by combustion of an atom of carbon from coal.
Which yields more energy - one kilogram or uranium or one kilogram of coal?
The uranium has nuclear energy and the coal has chemical energy. Nuclear is thousands of times more powerful.
Does India has more nuclear fuel than America?
Uranium deposits are much larger in the US compared to India, and all power operation in the US is currently based on enriched uranium with a straight-through cycle, the fuel is enriched, loaded, unloaded and stored with no further use. Large deposits of uranium are also found in Australia and Canada. In India the reserves of indigenous uranium are not great, but there are considerable reserves of thorium. This can be used for power production but the process is much more complicated and involves some chemical handling of the spent fuel which is not carried out in the US at present, because there is no need. India is not a signatory to the NPT and threfore wants to have its own indigenous supply of fuel, and this has prompted intereest in the thorium cycle. With the new US/India deal this emphasis could change. The following description of India's involvement with thorium is taken from 'www.world-nuclear.com'.In India, both Kakrapar-1 and -2 units are loaded with 500 kg of thorium fuel in order to improve their operation when newly-started. Kakrapar-1 was the first reactor in the world to use thorium, rather than depleted uranium, to achieve power flattening across the reactor core. In 1995, Kakrapar-1 achieved about 300 days of full power operation and Kakrapar-2 about 100 days utilising thorium fuel. The use of thorium-based fuel was planned in Kaiga-1 and -2 and Rajasthan-3 and -4 (Rawatbhata) reactors. With about six times more thorium than uranium, India has made utilisation of thorium for large-scale energy production a major goal in its nuclear power program, utilising a three-stage concept: * Pressurised Heavy Water Reactors (PHWRs, elsewhere known as CANDUs) fuelled by natural uranium, plus light water reactors, produce plutonium. * Fast Breeder Reactors (FBRs) use this plutonium-based fuel to breed U-233 from thorium. The blanket around the core will have uranium as well as thorium, so that further plutonium (ideally high-fissile Pu) is produced as well as the U-233. Then * Advanced Heavy Water Reactors burn the U-233 and this plutonium with thorium, getting about 75% of their power from the thorium. The used fuel will then be reprocessed to recover fissile materials for recycling. This Indian program has moved from aiming to be sustained simply with thorium to one "driven" with the addition of further fissile uranium and plutonium, to give greater efficiency.
Coal fired plants release 100 times more radioactivity than nuclear power plants due to the natural presence of thorium and uranium in the coal true or false?
FALSE
How many more times energy does uranium release compared to oil?
1 000 000
How many tons of uranium ore are needed to make one kilo of enriched uranium?
A Wikipedia article (see link below) gives the concentration of uranium in ore as 0.01 to 0.25 percent, which is a wide range. If we take 0.1 percent as typical, then 1 tonne (1000Kg) of ore would produce 1 Kg of uranium. This is natural uranium, which is normally enriched by about six times to produce suitable enriched uranium for fuel, so you can say that about 6 tonnes of ore would be needed to give 1 Kg of enriched uranium, but there is considerable variation of this from one source of ore to another
Is solar energy more efficient than nuclear energy?
Nuclear Energy is able to produce a constant ammount of energy at all times where as solar energy does not.
Does nuclear fusion produce much less energy per atom than nuclear fission?
Nuclear fusion produce energy 400 times more than nuclear fission for the same mass.
How nuclear technologies produce enermouse amount of energy?
Nuclear fission produces energy 2.5 million times that of carbon of same mass. Nuclear fusion produces energy 400 times that of nuclear fission of same mass.
Does a copper wire produce heat energy when it is pounded several times by a hammer?
Yes. Well, No. It actually converts some of the kinetic energy of the hammer blows into heat energy.
Why do nuclear reactions produce so much energy?
One of the laws of the universe is that matter and energy can't be created nor destroyed. But they can be changed in form. Albert Einstein's mathematical formula explains this as: E=mc2 or [E]nergy equals [m]ass times c2 (c is the speed of light). When the nucleus is split into two fragments the binding energy of the subatomic particles is released. The fission also releases two or three free neutrons, which can collide with other nuclei, causing a chain reaction. The energy released from one uranium nucleus is about 50 million times that of a carbon atom combining with an oxygen atom in burning coal.
