It is estimated that 1 kilogram of U235 can produce approximately 24,000 MWh of electricity in a nuclear reactor. This amount can vary depending on the efficiency of the reactor and the specific conditions of operation.

What is energy stored for use at a later time?

Energy stored for use at a later time is often referred to as potential energy. This type of energy can be stored in various forms such as chemical energy in batteries, gravitational potential energy in objects lifted off the ground, or elastic potential energy in stretched rubber bands.


In a reactor what is nuclear energy produced in?

It is produced in the fuel rods by fission of the U235 nuclei. Each fission produces a certain amount of heat, and this is transferred to the water or gas which is pumped past the fuel, by contact heat transfer.


How does uranium boil water to produce electricity?

Uranium, especially the isotope U235, has a large, unstable nucleus. It's unstable because all the positively charged protons in the nucleus are trying to repel each other. They are being held together by the strong nuclear force. Since strong force can only act over very short distances and the U235 nucleus is so large the nucleus is unstable. It tends to want to split into two smaller and thus more stable elements. When this happens it is called nuclear fission. In nuclear power plants we can split the U235 atom on purpose by hitting it with something. This something is a neutron. The neutron has no charge so it can smash into the nucleus and not just bounce off like proton would. Strangely it all works best if we use a slow moving neutron instead of a fast one. A fast neutron, because of quantum smearing, isn't in one place long enough to have any effect. A slow one, though, can be captured briefly by the U235 nucleus. Once the neutron is captured the nucleus is too large to hold together any longer splits apart. The really neat part is that the mass of the nucleus before it split and the mass of all the pieces afterward are different. Something has gone missing. A very small bit of mass has disappeared. Only Albert Einstein can tell us where it went. His famous equation e=mc^2 tells us that a small amount of mass can become a large amount of energy, and that is just what happens in nuclear fission. The missing mass becomes energy, in this case heat energy. The heat boils water. The steam turns a turbine which spins a generator, making electricity.


What fuels are used in nuclear power production?

The primary fuels we generally see used in nuclear power plants are the fissile materials uranium and plutonium. In the case of uranium, the metal is recovered from the ground, and is then processed and refined for use as fuel. In reactors using enriched uranium, the uranium will have to undergo considerable processing to increase the concentration of the U-235 isotope that is fissionable. (Natural uranium is mostly U-238.) In the case of plutonium, we can make it by exposing U-238 to neutron flux in an operating nuclear reactor.


Is u235 stable?

No, uranium-235 (U-235) is not stable. It is a radioactive isotope that undergoes radioactive decay, emitting particles and energy in the process.

Is the uranium-235 isotope the most commonly used fuel in fission power plants?

Yes U235 is the fissionable isotope of Uranium. Natural Uranium contains only about 0.7 percent U235, which is enough to produce fission only with a good moderator such as graphite or heavy water. In light water reactors the Uranium has to be enriched to about 4 percent U 235.


How much coal gives same energy as 1kg of uranium fuel pellets?

I have a figure but this is for 1 kg of Uranium 235, normally reactor fuel is about 4 percent of this isotope, so the amount of coal would be divided by 25 if we are talking about uranium as used in PWR or BWR reactors. Also this figure is for complete use of the U235, whereas for practical reasons of maintaining reactor performance, fuel is unloaded and replaced before it is all used up. So bearing in mind the above, 1 kg of U235 will produce as much energy as 1500 tons of coal. Let's try: 1kg of U235 (3,75%) has 83,14 TJ/kg. 1J=1Ws (3600Ws=1Wh). 1TJ=1000GJ=1 mio MJ 1kg of coal has 6000Wh/kg. I get 3850tons.


What is the process of manufacture of nuclear energy?

Nuclear energy to produce electricity is obtained from nuclear reactors, which are assemblies of uranium rods surrounded by a moderator and which can be made to produce a chain reaction of fissioning of the active part of the uranium (U235), which produces heat. The heat output raises steam either in separate boiler units (PWR) or within the reactor pressure vessel (BWR), which is then used to drive a steam turbine/generator which operates similarly to one in a coal or gas fired plant.


How many neutrons are in Element 92?

Element number 92 is Uranium and there are two main isotopes - U235 and U238. In U235 there are 92 protons so there are 235 - 92 = 143 neutrons. In U238 there are thus 146 neutrons


Fuel consumption Nimitz aircraft carrier?

A Nimitz class CVN uses approximately the weight of a paper clip worth of U235 per day at an average underway power. I cannot disclose the weight of U235 upon initial fuel load due to it being classified, but It is not near as much as one would expect for the ship to run for 20-25 yrs.


What is the difference between using uranium for power or bombs?

In power reactors the fuel is uranium enriched slightly to about 4 percent U235 (the fissile isotope), whereas for a bomb you need the U235 as high as possible, in the high 90's I believe.

The concentration of U235 in the atomic bomb?

The references I have state Oralloy is 93.5% U235. Oralloy (Oak Ridge Alloy) was used in US Uranium atomic bombs as the fissile material. However they also say that any enrichment 20% U235 or higher is fissile and could be used to make a bomb, it would require a higher critical mass to work though. One source I have states that early Soviet Uranium atomic bombs used ~97% U235, but the US felt this level of enrichment to be unnecessary and excessively expensive.


How is electicity manufactured?

As everybody know that electricity is a form of energy.The basic principle is that energy can be converted from one form to another,but it cannot be manufactured. There are many ways to generateelectricity. The various sources are 1.solar 2.wind 3.nuclear power, 4.fossil fuels and coal. The first two are renewable sources and the later are non-renewable sources. Solar energy: Here the heat energy from sun is used.this heat is used in genarating steam which in turn drives turbine to produce electricity. Wind energy:Here the heavy wind turns the huge wings of the wind mill which inturn turns the armature placed between magnetic field.Thus change in magnetic flux generates electricity. Nuclear power, fossil fuels and coal: In both the cases the fuel used to generate heat varies.But the principle to produce electricity is same. In nuclear power plant,due to fission reaction of U235,heat is generated. In later case ,fossil or coal is burnt to generate heat. The heat generated is used in steam generator to produce steam which in turn runs turbines to generate electricity.
