Name two possible fuel sources for a nuclear reactor?
Uranium-235 and Plutonium-239 are two possible fuel sources for a nuclear reactor. These isotopes are fissile materials that undergo nuclear fission reactions to generate heat in a controlled manner for producing electricity.
Is plutonium rare where is it most abundant?
Plutonium is an artificial chemical element, obtained by nuclear reactions and separated by reprocessing of burned nuclear fuel - as a byproduct plutonium is not so rare. Plutonium is found in the nature with some uranium ores, but only in ultratraces.
How much plutonium was USED in little boy?
The Little Boy atomic bomb used about 64 kilograms (141 pounds) of highly-enriched uranium-235, not plutonium. Plutonium was used in the Fat Man bomb, which used about 6.2 kilograms (13.6 pounds) of plutonium.
What letter would a chemist use in front of 235 or 238?
U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.
Fissionable fraction of fuel in a nuclear reactor?
In light water reactors the new fuel has about 4 to 5 percent U-235, which is the fissionable part, the rest being U-238. In some countries mixed oxide fuel is used (MOX) which contains some Plutonium as well as U-235, but the fissionable content is much the same. Heavy water or graphite reactors can use natural uranium, which contains 0.7 percent U-235.
How rare is plutonium U-235?
unfathomably
What does U-235 plus U-238 plus plutonium make when combined?
An alloy or a mixed oxide
What is the alpha decay of plutonium 239?
The daughter isotope of Pu-239 is U-235.
What is the halflife of plutonium 235?
The half life of plutonium-235 is 25,3(5) minutes.
Similarties between uranium-235 and plutonium-239 in nuclear reactors?
Uranium 235 and Plutonium 239 are fissile elements, fissionable with thermal neutrons.
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
What 2 radioactive elements were chosen for the atomic bomb?
Uranium-235 and plutonium-239 were the two radioactive elements chosen for the atomic bomb dropped on Hiroshima and Nagasaki.
Which metal isotopes are generally used in atom bombs and nuclear reactors?
Nuclear reactors usually use uranium. U-235 is the isotope that undergoes fission, but it is usually only about 5% of the initial uranium in the fuel, the rest is U-238 which is not fissile itself but during reactor operation some turns into plutonium which is fissile and starts to contribute to the fuel output as the U-235 gets depleted. Atom bombs usually use plutonium-239 but can also be made from pure U-235.

Is there plutonium in a nuclear power plant?
Yes, plutonium can be a nuclear fuel. It is formed in a reactor by U-238 (most of the fuel in fact) absorbing a neutron and becoming Pu-239. This is also fissile, so it compensates to some extent for the depletion of the U-235 as the reactor operates.
What is the element uranium used for in warfare?
Depleted Uranium, 0.2% U-235 99.8% U-238: Armor piercing antitank Gatling gun bullets and tank armor plateHighly Enriched Uranium, 93.5% U-235 6.5% U-238: Fission bomb coresReactor Produced Uranium,
Is Uranium 238 a good nuclear fuel?
No, because it does not fission like U-235 does. However it does transmute under neutron irradiation to plutonium, which if separated out can then be used in fuel, this is called MOX or mixed oxide fuel, and is part U-235, part Pu-239 in oxide form.
