How do you find the specific energy of uranium?
Total energy released: =1.845×1022 atoms)x(200x106eV)x(1.60×1019 J/eV) = 5.9×1011 J Therefore specific energy of natural uranium = 5.9×1011 J/kg.
The fission of 1 g of uranium or plutonium per day liberates about 1 MW. This is the energy equivalent of 3 tons of coal or about 600 gallons of fuel oil per day, which when burned produces approximately 1/4 tonne of carbon dioxide.
With a complete combustion or fission , approx. 8 kWh of heat can be generated from 1 kg of coal, approx. 12 kWh from 1 kg of mineral oil and around 24,000,000 kWh from 1 kg of uranium-235. Related to one kilogram, uranium-235 contains two to three million times the energy.
About 10% of the world's electricity is generated from uranium in nuclear reactors. This amounts to over 2500 TWh each year, as much as from all sources of electricity worldwide in 1960. It comes from about 440 nuclear reactors with a total output capacity of about 390,000 megawatts (MWe) operating in 32 countries.
Energy released per fission is 200 MeV.
To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in ...
The amount of energy released in the case of nuclear reaction is generally very large compared to the burning of coal. So, the energy released in fission of 1 kg of U-235 is equivalent to burning of 2500 ton of coal.
1 kg of uranium can power most cities for weeks. Or the entire city of New York for 2 days : r/interestingasfuck.
About 27 tonnes of uranium – around 18 million fuel pellets housed in over 50,000 fuel rods – is required each year for a 1000 MWe pressurized water reactor. In contrast, a coal power station of equivalent size requires more than two and a half million tonnes of coal to produce as much electricity.
From the outset the basic attraction of nuclear energy has been its low fuel costs compared with coal, oil and gas-fired plants. Uranium, however, has to be processed, enriched and fabricated into fuel elements, and about half of the cost is due to enrichment and fabrication.
How long does uranium last in a reactor?
To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that uranium fuel up.
The world's present measured resources of uranium (6.1 Mt) in the cost category less than three times present spot prices and used only in conventional reactors, are enough to last for about 90 years. This represents a higher level of assured resources than is normal for most minerals.
The total binding energy released in fission of an atomic nucleus varies with the precise break up, but averages about 200 MeV* for U-235 or 3.2 x 10-11 joule. This is about 82 TJ/kg.
Uranium is an abundant metal and is full of energy: One uranium fuel pellet creates as much energy as one ton of coal, 149 gallons of oil or 17,000 cubic feet of natural gas.
According to the NEA, identified uranium resources total 5.5 million metric tons, and an additional 10.5 million metric tons remain undiscovered—a roughly 230-year supply at today's consumption rate in total.
The fission of 1 kg of uranium produces 8.0×1013 8.0 × 10 13 J of energy.
The uranium was valued at Rs 3 crore per kg.

- Energy given out = mass of water × 4.2 × temperature change.
- Energy measured in joules, J.
- 4.2 is the specific heat capacity of water, J/g°C.
- Temperature change = temperature of water after heating – temperature of water before heating.
How do you calculate energy in joules?
If you multiply the number of watts by the number of seconds, you'll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.
According to the Union of Concerned Scientists, a nuclear bomb needs about 33 pounds (15 kilograms) of enriched uranium to be operational.
Nuclear power plants are expensive to build but relatively cheap to run. In many places, nuclear energy is competitive with fossil fuels as a means of electricity generation. Waste disposal and decommissioning costs are usually fully included in the operating costs.
But though it was once true, that assumption has actually been obliterated by a recent decline in solar and wind costs over the past decade. When it comes to the cost of energy from new power plants, onshore wind and solar are now the cheapest sources—costing less than gas, geothermal, coal, or nuclear.

In 2020, Kazakhstan had uranium reserves amounting to approximately 344 thousand metric tons, making it the country with the largest uranium reserves in the world.
The denser the projectile, the harder the impact for a given size. DU is almost twice as dense as lead, making it highly suitable. The other metal used for anti-tank rounds is tungsten, which is also very hard and dense. When a tungsten rod strikes armour, it deforms and mushrooms, making it progressively blunter.
Reactors run smoothly and reliably for up to two years at a time, but they need maintenance and inspection. Some of this can only be done when the reactor isn't running. So, the refueling periods—three weeks or so—are periods of intense activity.
The biggest nuclear power plant in the world is Hanul Nuclear Generating Station in South Korea. It has an annual output of 48.16 billion kWhs (2016). The second biggest nuclear plant is Kori Station, South Korea. It has a capacity of 7489 MW and generated 43.148 billion kWh in 2016.
Breeder reactors can power all of humanity for more than 4 billion years. By any reasonable definition, nuclear breeder reactors are indeed renewable. However, benefiting from this billion-year sustainability requires improvements in reactor construction performance and public acceptance.
What is the cheapest form of energy?
And there is some very good news for the planet: Solar and wind power, at the scale that a major utility would deploy them, are now the cheapest form of power. They're a bit less expensive than natural gas-fired power plants and considerably cheaper than coal and nuclear.
Nuclear Has The Highest Capacity Factor
As you can see, nuclear energy has by far the highest capacity facto r of any other energy source. This basically means nuclear power plants are producing maximum power more than 92% of the time during the year.
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.
The United States has eschewed reprocessing because of concerns about proliferation — that is, the risk that the material could be diverted for weapons — but other countries, such as France, do reprocess used fuel in civilian nuclear reactors. Recently, fresh interest in this option has emerged in the States.
That's right! Spent nuclear fuel can be recycled to make new fuel and byproducts. More than 90% of its potential energy still remains in the fuel, even after five years of operation in a reactor. The United States does not currently recycle spent nuclear fuel but foreign countries, such as France, do.
Depleted uranium can be disposed of as low-level radioactive waste if it is converted to chemically stable uranium oxide compounds, such as triuranium octoxide (U3O8) or uranium dioxide (UO2), which are similar to the chemical form of natural uranium.
Kazakhstan. Kazakhstan is the world's largest uranium producer, with some 19,477 tonnes of U3O8 (43 million pounds) in 2020, 41% of world supply.
In 2020, the United States was the largest uranium consumer worldwide, using a total of 18,300 metric tons of uranium.

The energy released by fission of one `U^(235)` atom is 200 MeV.
Can you hold uranium?
With a half-life of 4 billion years, uranium is only very weakly radioactive. In fact, since uranium is a heavy metal, its chemical toxicity is actually more of a danger than its radioactivity. If you touch it directly with your hands, you should wash your hands afterwards.
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity.
The fission of 1 g of uranium or plutonium per day liberates about 1 MW. This is the energy equivalent of 3 tons of coal or about 600 gallons of fuel oil per day, which when burned produces approximately 1/4 tonne of carbon dioxide.
8 kWh of heat can be generated from 1 kg of coal, approx. 12 kWh from 1 kg of mineral oil and around 24,000,000 kWh from 1 kg of uranium-235.
Plutonium, both that routinely made in power reactors and that from dismantled nuclear weapons, is a valuable energy source when integrated into the nuclear fuel cycle. In a conventional nuclear reactor, one kilogram of Pu-239 can produce sufficient heat to generate nearly 8 million kilowatt-hours of electricity.
During 2017, owners and operators of U.S. nuclear power plants purchased 40 million pounds of uranium from foreign suppliers. Canada, Australia, Russia, Kazakhstan, and Uzbekistan represented the top five countries of origin and together accounted for 84% of total U.S. uranium purchases in 2017.
The simple answer is: the earth's crust contains 2,8 parts per million (ppm). That's enough uranium to serve us until the time the sun turns into a red giant, more than a billion years from now.
During 2017-2021, US nuclear utilities bought an annual average of 17,500 tonnes of natural uranium and 16,600 tSWUs, including 2,400 tonnes of uranium and 3,300 tSWUs per year from Russia.

Hence, Total Energy released = 8. 19×1013J.
How much energy does a gram of uranium-235 produce?
➢ 1 gram of U-235 gives 1011 joules.
The energy released by fission of one `U^(235)` atom is 200 MeV.
New Page 1. During nuclear changes, either some mass is converted into energy or some energy is converted into mass. Which occurs is dependent upon the specifics of the individual reaction. From this change in mass we can calculate its energy equivalent using Einstein's equation, E = mc2.
- Energy given out = mass of water × 4.2 × temperature change.
- Energy measured in joules, J.
- 4.2 is the specific heat capacity of water, J/g°C.
- Temperature change = temperature of water after heating – temperature of water before heating.
These fragments, or fission products, are about equal to half the original mass. Two or three neutrons are also emitted. The sum of the masses of these fragments is less than the original mass. This 'missing' mass (about 0.1 percent of the original mass) has been converted into energy according to Einstein's equation.
Hence 9 x 10¹⁰ J of energy is liberated when 1 mg of uranium-235 is completely destroyed in an atomic bomb.

The fission of one uranium-235 atom releases about 200 MeV. Multiply that by 1.244*10^24 for 2 moles and you get about 2.5*10^26 MeV or about 4.0*10^13 Joules.
The energy released by the fission of one uranium atom is 200 MeV.
Basically you divide Avogadro constant by the atomic mass of the element to find the number of atoms of that element in one gram. So Uranium-235 contains 6.02214179×1023 / 235 = about 2.5626135×1021 atoms per gram.
