Here are the solutions to your questions: --- QUESTION 3 3.1 Indicate whether the following statements are TRUE or FALSE: 3.1.1 In a nuclear reactor core, inserting control rods deeper accelerates fission. False. Control rods absorb neutrons. Inserting them deeper reduces the number of neutrons available for fission, thus decelerating the reaction. 3.1.2 In a pressurised water reactor, graphite or xenon is used as a moderator. False. In a Pressurised Water Reactor (PWR), water* (specifically light water) is used as the moderator. Graphite is used in other reactor types, and xenon-135 is a fission product that acts as a neutron absorber (poison), not
