To solve the question, "In a nuclear reactor, the chain reaction stops if...", we need to understand the role of control rods in a nuclear reactor. ### Step-by-Step Solution: 1. **Understanding Chain Reactions**: In a nuclear reactor, a chain reaction occurs when a nuclear fission event causes additional fission events. This process needs to be controlled to prevent overheating and potential meltdowns. 2. **Role of Control Rods**: Control rods are made of materials that absorb neutrons (such as boron or cadmium). By absorbing neutrons, they reduce the number of neutrons available to continue the chain reaction. ...
