Years after the earthquake and tsunami that triggered the unprecedented trio of meltdowns at the Fukushima Daiichi nuclear power plant, scientists and engineers are still struggling to control an ongoing crisis at the wrecked plant. What's next for Fukushima? What's next for Japan?
Nuclear power produces almost a fifth of the world's electricity. Supporters say it's safe, cheap and - best of all - the answer to global warming. Critics say it's not safe or cheap, and it won't really help with the global warming problem. So who's right? This program presents the arguments for and against, with relevant background information.
This program covers a number of advanced topics. Understand the use of water to vary reactor power, as well as different methods of mining uranium, and witness a specific example of a fission reaction.
