The US is the only country with permanent storage for low & intermediate-level nuclear waste. But we're one of the few countries with nuclear power plants that don't have a plan for high-level waste. Dr. Kathryn Huff, Assistant Secretary, Office of Nuclear Energy at DOE, and Dr. Allison Macfarlane, Former Chairman of the Nuclear Regulatory Commission, discuss potential solutions.

One solution to reducing carbon emissions is to capture and store them underground. But there are challenges in capturing, transporting and storing the CO2, and determining who will pay for it. Dr. Sallie Greenberg, formerly with the Illinois State Geological Survey, and Dr. Julio Friedmann, Chief Scientist at Carbon Direct, discuss current projects and how CCS could contribute in the future.
