Uranium-235 and Uranium-238 are chemically identical. They undergo the same reactions with other elements. How are U-235 and U-238 different when it comes to nuclear reactions?

Question

anonymous · Answer

I know that U-235 is a fissile material that produces thermal neutrons used in classic nuclear reactions and U-238 is a fissile material used in breeder reactions, which produce more fuel. And also, they contain different amounts of neutrons, which controls the reactions. Is there any other differences I should include?
