How much activity is in 25 kilograms of 5 percent enriched uranium?
To calculate the activity of the uranium, you would need to know the specific activity of the enriched uranium sample. Activity is measured in becquerels (Bq) or curies (Ci) and it indicates the rate at which a sample undergoes radioactive decay. The specific activity takes into account both the enrichment level and the total mass of the sample.
What material does a nuclear power station use for energy?
Most nuclear power stations use uranium enriched to 3% uranium-235 isotope. The nuclear power stations in France include some reprocessed plutonium mixed with the enriched uranium. A small number of nuclear power stations were designed with fast neutron breeder reactors and used uranium enriched to as much as 93.7% uranium-235 isotope. As more of the uranium-238 (or thorium-232) in the breeding blanket was transmuted to fissionable plutonium (or uranium) isotopes, the breeding blanket material would be reprocessed and these fissionable isotopes would be used to replace the original spent uranium. But only a small number of such nuclear power stations were built and the system for reprocessing of the breeding blanket material was not set up.
How much of Uranium is used in nuclear fuel?
A typical PWR has fuel assemblies of 200-300 rods each, and a large reactor would have about 150-250 such assemblies with 80-100 tonnes of uranium in all. It produces electric power in the order of 900 to 1500 MW.
Can you store uranium safely?
Natural uranium can only be made critical by graphite or heavy water, so it can be stored almost anywhere, but obviously as it is valuable it would be stored in secure premises and in good dry conditions. Enriched uranium as used in power reactors can be made critical by normal water so storage should be somewhere that has been made secure against flooding. Highly enriched uranium needs special arrangements as it can become critical simply by having too much too close together, and storing this type of uranium must be supervised by those who know the risks and how to avoid them.
Why is nuclear energy not considered renewable?
Because there is only a limited amount of "fissle nuclides" sitting in the ground waiting to be dug up, these are Uranium, Plutonium and Thorium (less common). However we won't be running out soon, 3kg of natural (un-enriched) uranium would power the entire USA for a year. One problem is that quite a lot of uranium is being "shipped" to Iraq in the form of munitions.
How much does a baseball full of enriched uranium weigh?
Uranium has a density of 19 grams/cubic centimeter. The difference between natural U and slightly enriched U is hardly worth considering. Work out the volume of the baseball from V = 4/3 x Pi x R3, R being half the diameter.
What is enriched uranium?
Enriched uranium is uranium that has had its U-235 isotope content elevated above what it would be when we refine natural uranium after recovering the metal from ore.We know that U-235 is the desired fissionable isotope of uranium, but it is the isotope U-238 that is present in over 99% of all the naturally occurring uranium we mine and recover. We have to put the uranium through a process to separate the U-235 from the U-238. As these two isotopes are chemically identical, it takes a mechanical process to separate them. After running the uranium through a process designed to take advantage of the difference in the mass of the two atoms, the industry will recover uranium with a very high percentage of the U-235 isotope, and this is called enriched uranium.If uranium is enriched to a point where there is up to about 20% U-235, it is low-enriched uranium. Above that 20% mark we see highly enriched uranium. Above about 85%, we call the product weapons-grade uranium. A link can be found below for more information.
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
What would happen if a nuclear warhead was fired into 500kg of enriched uranium?
A pile that large of enriched uranium would already be supercritical. It would have killed everyone involved in piling it up with radiation doses in the 10,000 REM range (almost instant neurological death) and have completely melted down and caught itself on fire, dispersing as uranium oxide smoke. There would be no pile for the warhead to "hit".
How do you spell inialate?
That would be 'Annihilate'.

Why would it be bad if you lost uranium?
1. Possible contamination of soils, waters, vegetation. 2. Malicious use by a madman or foe. 3. Intoxication with uranium or irradiation (in the case of highly enriched uranium or irradiated uranium). 4. Other types of accidents depending on the quantity, chemical form, physical form or enrichment in 235U.
How much of the US would blow up from 1 kilogram of uranium?
It is not possible for 1 kilogram of uranium to "blow up" on its own like a bomb. However, if properly enriched and designed, 1 kilogram of uranium could potentially create a nuclear explosion, which would have devastating consequences within a significant radius.
What would be a good sentence with the word annihilate?
"Hitler set out on a systematic campaign to annihilate the entire Jewish race."

Is the inside of a baseball identical to the inside of an atom bomb?
The inside of an atom bomb is not the same as the inside of a baseball, but the fissile material (enriched uranium/plutonium) contained in an atom bomb could be about the same size as a baseball. The material is surrounded by shaped explosives, detonators, control circuits and a suitable casing. If a baseball was the same as an atomic bomb, nobody would play the game due to an unacceptable risk of vapourisation or radiation poisoning.
