The Future of Nuclear Energy: Have we entered a new era?

Are Climate Change, War in Ukraine, Inflation, and Fossil Fuel Supply Shortages Driving a Resurgence in Nuclear Energy?
With the Russian cutoff of natural gas to Europe and the trends toward de-globalization and supply chain security, the issue of energy security has risen to the top of national agendas throughout the world. California’s legislature and governor have approved a 5 year extension of the state’s last nuclear plant, Diablo Canyon, which generates 8% of the state’s energy. Japan’s prime minister has called for re-starting its nuclear plants and for a broader policy shift toward nuclear. Germany is postponing the closure of two of its remaining nuclear plants, suggesting perhaps a second Energiewende (completing a U-turn?). France is considering up to 14 new reactors. China has 21 nuclear plants under construction. In the US, the Inflation Reduction Act provides subsidies for existing and advanced nuclear reactors. Many other countries are planning new reactors, too. These moves indicate a growing consensus that the world economy needs every megawatt of nuclear energy available.
Nearly every model of global energy demand points to the important role nuclear power must play to reduce carbon emissions. By how much can nuclear power reduce the world’s carbon emissions? Or, can renewables do it all?
“It is not a choice between the two. #solar will grow as fast as it physically can and won’t be 100%. Same with #wind, #geothermal, #hydro, #BiomassCCS, #efficiency, etc. You still have a huge political/resiliency hole that #nuclear has to fill. Every model shows it. #cleanfirm” - Jigar Shah (@JigarShahDC) August 27, 2022
The International Energy Agency projects that a doubling of the world’s nuclear output is required by 2050 to reach net zero energy.
The nuclear industry has a history of missing schedule and budget. Advocates of small modular reactors say they will be easier to build than larger ones. In the US, TerraPower and X-Energy have been chosen by the DOE to build small reactors based on new technology. China and Russia are building smaller reactors. More than $1.2 B of venture funding has gone into new fission technology in the past year. Is smaller, cheaper, faster the answer?
MIT Professor Jacopo Buongiorno, a world-wide leader in the nuclear industry, will discuss the latest developments in new technology, the changes in the market, needed policy support, opportunities for public education, new workforce requirements, career opportunities and other key issues.

Problem with Advanced Modular Reactors or ANY pebble bed design is you can't break the fuel down to recycle and so you only get a very very small portion of the energy potential of the fuel and it becomes impossible to eliminate the million year storage problem, and the fission products remain within the fuel so meltdown is not only possible but probable. BAD BAD BAD Design, CHEAP is NOT BEST. A much better approach is molten salt breeders because we can burn up all the minor actinides, fission products are NOT left in the fuel, and they are safe by way of physics not active mechanisms which invariably fail. Another Fukushima and you can forget moving forward with nuclear and likewise
if we don't fully address the waste problem it isn't going to get support.

Thanks a lot. Very insightful.
