The operation of a thermal nuclear reactor depends on several key components and the management of its products.
Explain the physical mechanism by which the moderator changes the speed of neutrons incident upon it.
Boron and cadmium are common materials used in control rods. Describe what happens to a neutron when it interacts with a control rod.
Describe the sequence of events that occurs when a thermal neutron induces fission in a nucleus of 92235U^{235}_{92}\text{U}92235U.
A significant challenge in nuclear power generation is the management of high-level waste (HLW).
Identify the primary source of HLW in a reactor and discuss the stages of its treatment and the physical problems associated with its long-term disposal.
Your answer should include:
128 exam-style questions on AQA A Level Physics Radioactivity (A-level only), covering Rutherford scattering (A-level only), $\alpha$ , $\beta$ and $\gamma$ radiation (A-level only), Radioactive decay (A-level only), Nuclear instability (A-level only), Nuclear radius (A-level only), Mass and energy (A-level only), Induced fission (A-level only), and Safety aspects (A-level only). Each one has a worked solution and a mark scheme showing where the marks go.
