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 … WebIn this video, we will explore What is Chain Reaction.

WebA chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats (Fig. 5.3 ). The process may be controlled (nuclear power) or uncontrolled (nuclear weapons). Figure 5.3. WebChain Reaction controlled by. Materials that absorb or capture neutrons are used in the reactor. Control Rods. Are inserted or withdrawn from the reactor to control the power level or shut down the reaction. Control Rods made of. Silver, cadmium, or hafnium. Withdrawing the Control Rods. Reduces the amount of negative reactivity in the core.

Web19 de mar. de 2024 · When a U235 atom disintegrates, it releases some neutrons. Some of those neutrons can be made to interact with other U235 atoms, causing them to disintegrate as well. Those "target" atoms release more neutrons when they disintegrate, and then those neutrons interact with still other U235 atoms, and so on. This is called a "chain reaction." WebThe fission process may produce 2, 3, or more free neutrons that are capable of inducing further fissions and so on. This sequence of fission events is known as the fission chain reaction, and it is important in nuclear reactor physics.. The chain reaction can take place only in the proper multiplication environment and only under proper conditions.Suppose …
