Fission af uran 235

WebIn nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, 235 U). A nuclear chain reaction … WebNuclear fission occurs when one atom splits into two, creating energy. Spontaneous fission occurs all the time. Uranium undergoes spontaneous fission at a very slow rate, and emits radiation. Uranium-235 (U-235) is only found in about 0.7 percent of uranium found naturally, but it is well-suited for producing nuclear power.
