What make Uranium fission?
Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
When does Parent and daughter isotopes occur?
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.
What uranium nucleus is fissile?
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
How much time takes uranium decays into led?
It takes billions of years for uranium to decay into lead. Uranium-238, the most common isotope of uranium, has a half-life of about 4.5 billion years, meaning it takes that long for half of a sample of uranium-238 to decay into lead-206.
What is a cascade in terms of refining uranium?
A cascade is a long series of identical, successive specific equipments used in the process of uranium enriching in the isotope 235U.
Which equation represents the alpha decay of plutonium 244?
The equation for the alpha decay of plutonium-244 is: [ ^{244}{94}Pu \rightarrow ^{240}{92}U + ^4_2He ]
What is the Uranium bomb?
A bomb containing highly enriched uranium (in the isotope 235U) as explosive.
What does the 235 refer to in uranium 235?
235 is the approx. atomic mass of the isotope 235U.
Describe the difference between weapons grade and reactor grade nuclear fuel?
Uranium in nature is only about 0.7% 235U. In order to have a chain reaction, the percentage of 235U must be increased by enrichment. The percentages of 235U in nuclear reactors are generally low, about 3% to 5%. For bombs, the percentage is generally 85% or more.
What make Uranium fission?
Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
What is the nuclear decay equation for uranium 235?
The equation for the alpha decay of 235U is: 92235U --> 90231Th + 24He representing the alpha particle as a helium nucleus. 235U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
When does Parent and daughter isotopes occur?
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.
The uranium decay chain ends when the final disintergration product is the stable element?
Yes, that's correct. The uranium decay chain ends with the stable element lead-206. As uranium-238 undergoes alpha and beta decay, it transforms through various radioactive isotopes before reaching lead-206, which is stable and not subject to further radioactive decay.
How many years will it take for 10g of radioactive uranium to decay into 5g of radioactive uranium?
Depending on the isotope: - for 235U: 7,038.108 years - for 238U: 4,468.109 years etc.
What is completed uranium?
You think probably to depleted uranium.Depleted uranium is uranium containing less than 0,2 % the isotope 235U.
What uranium nucleus is fissile?
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
Why is 235 isotope of uranium is superior to 233 or 238?
233U and 235U are two fissile isotopes; but 233U is now more expensive. 238U is only a fertile isotope in nuclear reactors with thermal neutrons.
