U-235 is better than U-238. U-235 is fissile, while U-238 is only fertile. Fertile means that splitting the atom with a neutron can release binding energy. Fissile means that and also that the event can release enough stray neutrons to continue the reaction, i.e. to cause a chain reaction.
What else can I help you with?
Which isotope used for the production of atomic energy?
The most common substances used as nuclear fuel are Uranium 235 and Plutonium 239. These isotopes are fissile, which means that they will fission (split) in a controlled manner when bombarded with high energy neutrons, and release energy in the form of heat. This heat is used to boil water in huge boilers. The resulting steam is used to drive steam turbines which generate electrical energy.
Which part of an atom participates in the reaction shown below U235 plus n and acirc and 134 and 146 Xe134 plus Sr100 plus 2n?
The nucleus of the Uranium-235 (U235) atom participates in the nuclear reaction by absorbing a neutron (n) to form an unstable compound nucleus, which then undergoes fission into Xe134, Sr100, and two neutrons (2n).
The energy released when atoms are split apart or fused together in atomic reactions?
The question is not specific. Is this question about the amount of energy released or how the energy released? I'll answer for both of them, the amount of energy to be released depends on the fuel like U235 and Pu239 etc, and mass of them. The energy is released by the conversion of mass into energy. when the U235 breaks into two other nuclei, there will be the mass defect. this will be converted into energy. i hope your problem is solved. other wise, please specify your question.
The concentration of U235 in the atomic bomb?
The references I have state Oralloy is 93.5% U235. Oralloy (Oak Ridge Alloy) was used in US Uranium atomic bombs as the fissile material. However they also say that any enrichment 20% U235 or higher is fissile and could be used to make a bomb, it would require a higher critical mass to work though. One source I have states that early Soviet Uranium atomic bombs used ~97% U235, but the US felt this level of enrichment to be unnecessary and excessively expensive.
What is the energy level of plutonium?
Weight for weight, Pu239 produces similar energy to U235. However reactor fuel as normally produced from enriched uranium, does not contain Pu. During operation, Pu239 is produced by irradiation of U238 with neutrons (U238 is of course the major part of the U in the fuel, only about 4 percent is U235). The build up of Pu239 compensates to some extent for the burnup of the U235. However as reactor operation continues, the Pu239 is also burnt up, and higher isotopes of Pu are produced, so eventually the fuel must be replaced. Pu with a high concentration of 239 was produced in quantity for weapons in the cold war period, by irradiating fuel for a deliberately short period. Some fuel has been produced with a mixture of U and Pu, this is called MOX fuel (mixed oxide). This has been used in Europe but I believe not in the US though proposals have been made. This would have the advantage of using up some of the surplus Pu239 which exists in the world after the cold war excess production.
What is the best way at producing electricity?
in order,- Fission, (u235) Fusion, (d-t) Fusion (sun) Antimatter, Zero point energy.
Is uranium nuclear fuel?
Yes, U233, U235, and U238 are all used as nuclear fuels.
What is energy stored for use at a later time?
Energy stored for use at a later time is often referred to as potential energy. This type of energy can be stored in various forms such as chemical energy in batteries, gravitational potential energy in objects lifted off the ground, or elastic potential energy in stretched rubber bands.
How could nuclear energy be used?
Nuclear energy is simply electricity produced by a nuclear reactor, which is just a different way to heat steam to turn a turbine. It is the same as normal electricity, actually it IS normal electricity.
Where does the nuclear enengy come from?
It comes from the fission of certain nuclei, mostly U235 and Pu239. Every fission of a nucleus of an atom of these materials releases a certain amount of energy as heat.
Can nuclear power plants produce material that could be converted?
Nuclear energy is released from the nucleus when U235 fissions, it appears initially as kinetic energy of the fission fragments, these are then stopped in the fuel material and turned to thermal energy. We can't use the nuclear energy directly.
What isotopes are in this process?
which process & which isotope u mention 1. nuclear reaction U235 & Pu239
What is being done to reverse nuclear power?
Some countries are transitioning away from nuclear power by phasing out existing nuclear plants and increasing reliance on renewable energy sources. Some governments are also investing in advanced nuclear technologies like Small Modular Reactors (SMRs) as a cleaner alternative to traditional nuclear power plants. Additionally, efforts are being made to improve safety protocols and address concerns about nuclear waste disposal.
What is fuel enrichment - nuclear?
Natural uranium contains approx 0.7 percent U235, the rest U238. The 235 is the useful fissile isotope. Some reactors using graphite or heavy water can use natural uranium, but light water reactors need to have the U235 proportion increased to about 4 percent. this is called enrichment.
What are in nuclear bombs?
Enough of either U235 or PU239 to form a critical mass and hence a large explosion
What are the isotopes in use in nuclear power plants and what reaction takes place?
Uranium is used as the feed fuel in nuclear power plants. Natural uranium contains 0.7 percent U235 but this is increased to about 4 percent for light water moderated reactors. The bulk of uranium is U238 and this is not productive, though some of it turns to plutonium during operation and this gives further energy output. The reaction with U235 and Pu239 is called fission, whereby the nucleus splits into two parts and releases energy
How much 1kg of u235 can produce electricity in areactor?
It is estimated that 1 kilogram of U235 can produce approximately 24,000 MWh of electricity in a nuclear reactor. This amount can vary depending on the efficiency of the reactor and the specific conditions of operation.
