| Processes involving changes in the nucleus of an atom, giving out energy. | Nuclear Reactions |
| How many types of nuclear reactions are there? | There are three types of nuclear reactions. |
| A type of nuclear reaction where an unstable nucleus decays into a more stable nucleus and emits radiation. | Radioactive Decay |
| What happens during radioactive decay? | An unstable nucleus decays into a more stable nucleus and emits radiation. |
| A nuclear reaction where a large unstable nucleus splits into two or more smaller nuclei and emits radiation. | Nuclear Fission |
| What occurs during nuclear fission? | A large unstable nucleus splits into two or more smaller nuclei and emits radiation. |
| A nuclear reaction where two small nuclei collide and form a larger nucleus, giving out thermal energy. | Nuclear Fusion |
| What happens during nuclear fusion? | Two small nuclei collide and form a larger nucleus, giving out thermal energy. |
| The release of energy, which occurs in all three types of nuclear reactions. | Energy Emission |
| Which type of nuclear reaction is currently used to generate electricity in nuclear power plants? | Only nuclear fission is currently used to generate electricity in nuclear power plants. |
| Nuclear fuel stores much more energy per kilogram than fossil fuels. | Energy Storage |
| Why is nuclear power more efficient and has a much lower running cost than fossil fuels? | Because nuclear fuel stores much more energy per kilogram than fossil fuels. |
| Nuclear power is very reliable. | Reliability |
| How long will it take for nuclear fuel to run out compared to fossil fuels? | It will take over 200 years for nuclear fuel to run out, while fossil fuels will run out faster than this. |
| Nuclear power doesn't release carbon dioxide, so it doesn't contribute to climate change. | Environmental Impact |
| Why doesn't nuclear power contribute to climate change? | Because it doesn't release carbon dioxide. |
| Nuclear power is very strictly regulated, which helps to make it safer. | Regulation |
| How does strict regulation affect the safety of nuclear power? | It helps to make nuclear power safer. |
| Harmful byproduct of nuclear power generation, remaining radioactive for millions of years, requiring costly long-term storage. | Nuclear Waste |
| What is nuclear waste and why is it a concern in nuclear power generation? | Nuclear waste is a harmful byproduct of nuclear power generation, remaining radioactive for millions of years, requiring costly long-term storage. |
| Process where nuclear power station parts become radioactive during operation, complicating decommissioning. | Radioactive Contamination |
| What is radioactive contamination, and how does it affect nuclear power station decommissioning? | Radioactive contamination is when parts of a nuclear power station become radioactive during operation, complicating decommissioning. |
| The costly process of shutting down and dismantling a nuclear power station due to radioactive contamination. | Decommissioning |
| What is decommissioning, and why is it costly for nuclear power stations? | Decommissioning is the costly process of shutting down and dismantling a nuclear power station due to radioactive contamination. |
| Significant expenses associated with building nuclear power stations, posing economic challenges. | High Construction Costs |
| What contributes to the high costs of building nuclear power stations? | High construction costs contribute to the economic challenges of building nuclear power stations. |
| While generally safe, nuclear power stations pose risks of causing widespread harm if accidents occur. | Safety Concerns |
| What safety concerns are associated with nuclear power stations? | While generally safe, nuclear power stations pose risks of causing widespread harm if accidents occur. |
