What are the fertile isotopes of Uranium?
There are many isotopes for uranium, the most abundant of them in nature are:Uranium- 234, having 142 neutron and 92 protonUranium- 235, having 143 neutron and 92 protonUranium- 238, having 146 neutron and 92 protonThe abundance of these three isotopes in natural uranium is:Uranium-234: 0.006 %Uranium-235: 0.720 %Uranium-238: 99.274 %
What else other than uranium 239 is the atomic bomb made of?
Not uranium 239, but uranium 235 and plutonium 239.
What are the three isotopes that will undergo neutron induced fission?
They are many but the most famous three are: uranium-233, Uranium-235, and Plutonium-239.Another answerUranium-235, uranium-238, and plutonium-239 are all capable of undergoing neutron induced fission. Actually there are other isotopes that also do this, but they are not commonly used as fuel.
Similarties between uranium-235 and plutonium-239 in nuclear reactors?
Uranium 235 and Plutonium 239 are fissile elements, fissionable with thermal neutrons.
Radiation is one of the long-term effects of a nuclear detonation wich of the fallowing type of radiation is emitted only during detonation?
Mostly Uranium 235, Uranium 238, and Plutonium 239 Also fission fragments. If your talking about any kind of radiation then it would be thermal radiation from the heat blast. When you split the Uranium atom you get 2 Neutrons, 2 protons + 2 fission fragments. 1 of the 2 neutrons will be uranium 235 and the other plutonium 239. the radiation from a nuclear blast will at first be heat. This will be continious until the energy that created it is depleated. Note Uranium 238 is weaker than Uranium 235 and it absorbs neutrons. Uranium 235 has a far greater Neutron density (99.3%) Uranium 238 = (0.7%)
Uranium 235 and uranium 238 are isotope they are chemically different why?
I LIKE PIGS IN A BLANKET I think ,because when hit Uranium-238 by a neutron, it becomes uranium-239, an unstable isotope which returns into neptunium-239, which then itself decays, with a half-life of 2.355 days, into plutonium-239. ------------------------ Differences in nucleus stability and nuclear cross sections for fission with thermal neutrons. Some details at: http://nuclearweaponarchive.org/Library/Fission.html
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
What is produced from uranium-238 in a breeder reactor?
Pu-239
Is uranium 238 a slow or fast neutron absorber?
uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
Why is uranium 238 not used as fuel?
Uranium-238 is a fertile nuclear material that is useful in producing fissile material (Plutonium 239)
What particles cant a fission reactor split?
The only nuclei which are split are Uranium-235 in new fuel, and plutonium-239 which is formed during operation from U-238.
What is the main fuel for a fission reaction?
Uranium 235....but Uranium 238 is also present and will absorb a neutron and become Plutonium 239 and adds approximately 10% of the net power in most commercial fuels used in the USA. Most people are not aware that a reactor produces many transuranic elements, not just Plutonium, and that all of these elements have isotopes suitable for reactor fuel.
