I'm giving a keynote talk on the future of nuclear energy at the Pacific Basin Nuclear Conference in Oct. There is a strong rational case for nuclear, but it's faced a lot of opposition since the 1980s. I'm curious: what is the single biggest concern you personally have about building more nuclear reactors around the world to meet the fast-growing demand for carbon-free energy as poor nations develop?

I'm giving a keynote talk on the future of nuclear energy at the Pacific Basin Nuclear Conference in October. I have my own opinions, but I'm curious what you and others think are the biggest obstacles nuclear faces today. What would you say is the single biggest concern you personally have about building more nuclear reactors around the world to meet the fast-growing demand for carbon-free electricity as previously poor countries develop?
