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.

∙ 12y agoThe uranium used in nuclear weapons is very enriched in the isotope 235U (more than 90 %.
The uranium used in nuclear power reactors is generally enriched in the range
2-5 %, in the isotope 235U.
The uranium used in nuclear reactors for research is generally enriched up to
20 %, in the isotope 235U.

How serious have nuclear reactor accidents been?
Between 1945 and 1987, there were 285 nuclear reactor accidents, injuring over 1,550 people and killing 64.
What is the difference between inductor and inductance?
Inductors can be used for a great many purposes. Terms, such as 'choke', 'reactor', etc., describe applications of inductors.
What is the function of a nuclear reactor of a nuclear plant?
simply, the nuclear reactor is the source of heat (or steam) for the nuclear power plant.
Block diagram of a nuclear power station?
The heart of a nuclear power plant is the nuclear reactor.
What is the name of the first Indian nuclear reactor?
The first Indian nuclear reactor's name is APSARA.
What is the difference between nuclear reactor and nuclearpower plant?
a nuclear reactor converts binding energy into heat. a nuclear power plant uses a nuclear reactor to generate electricity.
What is the difference between the nuclear reactions in a nuclear reactor and those in an atomic bomb?
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
What is the difference between a bioreactor and nuclear reactor?
A nuclear reactor uses either nuclear fission or nuclear fusion to generate electricity, while bio-reactors use the excretions of many animals to generate electricity.
What is the difference between the nuclear reactions taking place in the sun and in a nuclear reactor?
the suns nuclear reactions happen at extreme temperatures we do it at lower temps
What is the difference between the nuclear reactions taking place in the sun and the nuclear reactions taking place in a nuclear reactor?
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
How can you Describe the energy transfer in a nuclear reactor?
By going to a nuclear an. Asking somebody this question :D
What is the Japanese Nuclear Reactor?
A Nuclear Reactor.
Can you make a real ark reactor?
An Ark reactor as currently describe in comic is very much like a Nuclear Fuel Cell. Possibly convert energy from Nuclear reaction to power. Possibly a plasma nuclear fusion reactor. I believe in the future it could be made. See the link and compare the similarity of fusion reactor and Ark reactor.
What is artificial nuclear reactor?
An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
What is the difference between fuel of nuclear power plants and the fuel needed to construct a nuclear weapon?
Reactor grade material is usable in most nuclear power plants. Weapons grade material is required for nuclear weapons. For uranium the difference between reactor grade and weapons grade is the level of enrichment: less than 20% uranium-235 is reactor grade, greater than 20% uranium-235 (greater than 90% is prefered) is weapons grade. For plutonium the difference between reactor grade and weapons grade is the level of contamination with plutonium-241: any amount of plutonium-241 is OK for reactor grade, only low levels of plutonium-241 are acceptable in weapons grade as its spontaneous fission rate can cause the bomb to fizzle.
What is nuclear reactor kinetics?
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
Difference between breeder reactors and nuclear reactors?
The nuclear reactor is different from the breeder reactor because it generates energy through fission. Historically, in order to be called a breeder, a reactor must be specifically designed to create more fissile material than it consumes. this is what I've looked up and been able to find
