What do the '238' in uranium-238 and the '14' in carbon-14 mean?
* 238 is the atomic mass of a natural uranium isotope. * 14 is the atomic mass of a carbon isotope.
What does it mean if an isotope is fissionable?
It means the nucleus will fission or split into two halves (or near halves). Most frequent example is Uranium-235
How much neutrons have uranium?
Uranium has many isotopes and each isotope has a different number of neutrons (N). N = atomic weight of the isotope - atomic number of uranium (A=92) The number of neutrons of the isotope 92U238 is 238-92=146 and the number of neutrons of the isotope 92U235 is 235-92=143.
What does the uranium enrichment program mean?
The concentration of the isotope uranium 235 in natural uranium is approx. 0,7 %. Enrichment is the process which increase this concentration. The necessary concentration for military use - atomic bombs is more than 90 %. Also many nuclear reactors work with enriched uranium (but with only 3-5 % uranium 235).
What does it mean if a isotope is fissile?
Fissile means that an isotope is capable of supporting a sustained nuclear chain reaction.

What radioisotope is used in nuclear fuel rods?
You presumably mean Uranium-235 which is the fissile isotope of uranium. New fuel rods contain uranium enriched in U-235 to about 4 percent, in the form of uranium dioxide, and encased in a zircaloy sheath. There is nothing else.
How do you separate uranium from water?
What do you mean. Uranium is not soluble in water.

What does bombardeo mean?
bombing, shelling air raid, air attack bombardment
How many pounds of coal do you have to burn to equal the potential energy of one pellet of uranium?
# I'm not clear what size pellet you mean. However for Uranium235 (the fissile isotope), if it is fully used up, 1 kg will give as much energy as 1500 tonnes of coal, ie 1,500,000 kg of coal, so that is the ratio, 1,500,000 to 1. Of course uranium as loaded into the reactor is actually about 4 percent U235, the rest U238 which is not fissile, so the U235 is 1/25 of the total weight of uranium, and if you mean the total uranium weight you therefore have to reduce this ratio by 25, and get 60,000 to 1.
What does uranium mean?
Uranium is a chemical element, atomic number 92 in the periodic table. The name uranium is derived from the name of the planet Uranus.
What does it mean if a isotope is fissile?
Fissile means that an isotope is capable of supporting a sustained nuclear chain reaction.
Why can ordinary uranium not be used to fuel a reactor cooled by ordinary water?
Because "ordinary" uranium is mostly 238U, which won't fission and create a chain like its lighter cousin 235U will. When critical mass is achieved with the 235U isotope of uranium, fission will occur spontaneously. Or with a significantly enriched uranium fuel (one where the natural concentration of 235U has been increased a bunch so the fuel has a much higher percentage of this isotope), fission and a chain reaction is also possible. But with just natural uranium, a big pile of it will just sit there. It won't fission and create a chain reaction. Note that 238U is radioactive and decays over time because it is unstable, but it has a long half-life. Also, the fact that it's unstable (radioactive) doesn't mean it's fissile. It isn't.
What does Half-Life of Uranium 235 mean?
Uranium is a radioactive element and conteneously disintegrate into smaller element, that time in which 1g of uranium becomes half g is known as half life period of uranium.
