What else can I help you with?
What is the alpha decay of plutonium 239?
The daughter isotope of Pu-239 is U-235.
What is the nuclear decay equation for plutonium 239?
The first step is an alpha decay to (guess what!) uranium 235. You can probably take it from there.
When was Illadelph Halflife created?
Illadelph Halflife was created on 1996-09-24.
What percentage of nuclear waste can be recycled?
High level nuclear waste consists of fuel that has been used and discharged. It probably contains about 1 percent U-235, some highly active fission products, some plutonium, and the rest (the majority) U-238. The fission products are of no use, except possibly for medical or industrial purposes. The plutonium if separated out could be used to make mixed oxide fuel (MOX). The uranium with a small amount of U-235 could be put through an enrichment plant to increase the U-235 content. Low enriched uranium could also be used in heavy water reactors (CANDU). None of these things can be done however without a spent fuel processing plant which does not exist in the US (not for commercial fuel anyway)
Does all nuclear wastes completely disappear after 50 years?
Not by a long shot. The most radioactive isotopes will decay very rapidly and be safe in much less than 50 years (e.g. iodine-131 with a halflife of about 8 days will be gone in less than 2 months), but less radioactive isotopes will decay so slowly they can be around for hundreds of thousand of years (e.g. plutonium-239 with a halflife of 24400 years will be gone in under 200000 years) to longer than the age of the universe (e.g. uranium-238). Slightly oversimplified, the most dangerous isotopes in nuclear waste tend on average to disappear first with less dangerous isotopes persisting for longer periods.
How rare is plutonium U 235?
Plutonium-235 is relatively rare compared to plutonium-239, which is the more common isotope of plutonium. Plutonium-235 makes up less than 1% of naturally occurring plutonium. It is typically produced in nuclear reactors through the neutron capture process.
How rare is plutonium U-235?
unfathomably
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.
Why was plutonium used in Fat Man?
There are two materials that can be used to make an atomic bomb: Plutonium-239 and uranium-235. Of the two plutonium-239 is easier to acquire. By the end of the Manhattan Project the U.S. only had enough uranium-235 to make one bomb, and that was Little Boy.
What element was used to make the atom bomb?
Plutonium-239 for Nagasaki's Fat Man Uranium-235 for Hiroshima's Little Boyhydrogen
Which material type is more dangerous plutonium 239 or uranium 235?
Plutonium-239 is generally considered more dangerous than uranium-235 because it is highly toxic and poses a greater risk of radiation exposure. Plutonium-239 is a significant nuclear proliferation concern due to its use in nuclear weapons.
A radoiactive element often used in nuclear power stations?
Uranium 235 Plutonium
What elements and isotopes generate nuclear power?
Mostly uranium-235, also plutonium
What is the alpha decay of plutonium 239?
The daughter isotope of Pu-239 is U-235.
Which uranium isotope is the first step in the chain of events making plutonium-239?
Uranium 235
