- 15. Multiple ChoiceWhat might be a concern raised by community members if they were told that a nuclear power plant was going to be built in their neighborhood?the threat of a nuclear accident or spillthe air pollution generated by the plantcoal could be used to produce more energy per gram of fuelexcessive use of petroleum would leak into the water under the ground
- 16. Multiple ChoiceWhat is a chain reaction?When electrons are emitted causing electricityWhen a nuclear fission reaction occurs, the protons emitted can strike other nuclei in the sample, and cause them to splitWhen a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to splitWhen a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split
- 17. Multiple ChoiceWhat do control rods do in a nuclear reactor?Regulate the rate of reaction by absorbing and slowing neutronsProduce electricityProduce neutrons to increase the rate of reactionReduce heat produced by the uranium rods
