Final answer:
Nuclear power plants pose risks such as generating highly toxic radioactive waste with long half-lives, potential failures of complex control systems, and environmental impacts from mining operations for uranium.
Step-by-step explanation:
The risks associated with using nuclear power plants to generate electricity include the production of highly toxic waste, reliance on complex control systems, and the requirement of mining to obtain fuel. Notably, nuclear power plants produce radioactive waste, including uranium mill tailings and spent reactor fuel, which have long half-lives and pose health hazards for thousands of years. These plants also rely on sophisticated control systems that could fail due to human error. Additionally, the process of obtaining uranium requires mining operations, which can have environmental impacts.
