Everyday Explorations

Dr. Leslie Dewan believes that nuclear energy is a powerful tool to combat climate change. She has updated the design of the molten-salt reactor to keep its safety features and lower the cost of generating electricity. She hopes that this design can be used to generate electricity that is both carbon-free and cheaper than electricity generated from coal.
