checking in on the “nuclear rennaissance”

This article focuses on one particular failed nuclear power project in the U.S. but it checks in on the idea of a stalled “nuclear rennaissance” overall.

The South Carolina legislature conducted hearings about the project’s collapse. But it has fallen to the United States Attorney for South Carolina to outline internal decisions that led to project abandonment—via court filings, plea agreements, and indictments. These filings are proving to be the best documentation so far of criminal behavior related to projects that were part of a much-hyped “nuclear renaissance” that began in the early-2000s but has since petered out in the United States…

The fault for the shocking AP1000 misadventure falls squarely on the shoulders of Westinghouse and the involved utilities. They all fell victim to their own reactor-promotion propaganda but lacked the technical and management competence to pull off the projects as envisaged. With pursuit of large light-water reactors in the United States all but dead, the nuclear industry is now endlessly touting an array of “small modular reactors” and a dizzying menu of so-called “advanced reactors,” all of which exist only on paper. It’s unclear if there’s a path forward for this nuclear renaissance redux, and if there is, whether taxpayers will be put on the hook for financing some of it.

Bulletin of the Atomic Scientists

I can imagine an alternate history without Three Mile Island and Chernobyl, and where climate change was understood and taken seriously by the public and governments much earlier. Nuclear energy was embraced on a vast scale, homes, buildings, and transportation were mostly electrified, and the world economy grew for 50 years without the devastating carbon emissions that are now starting to wreck our planet’s ecology and threaten our food supply. No doubt, there are some accidents and waste storage/disposal problems in this world, but with an honest accounting of the cost of carbon pollution would this world be worse off? Maybe nuclear weapons proliferation would be worse in this world, but then again, maybe a world where civilian nuclear technology was more shared but controlled by international safeguards would feel less pressure for proliferation.

The other issue with nuclear power plants is they have incredibly high up front costs and are incredibly long-lived. As technology progresses, a nuclear power plant is going to be obsolete (i.e., not based on the latest technology) by the time you design it and get it in the ground, and then you are stuck operating it for the next 50 years. So you have to take a really long range view, governments have to shoulder a good portion of the risk, and you have to keep the R&D going in parallel even though you know it takes decades to pay off. All this is doable, it just takes leadership and discipline, which our species and civilization mostly lacks.

a new option for nuclear waste?

Can nuclear waste be stored safely in horizontally drilled fracking tunnels? Well, maybe…

Nuclear waste experts have contemplated deep-drilling for half a century, mostly by proposing to bore straight down into granite and crystalline rock. But tests of these techniques haven’t gotten very far, being blocked, on occasion, by the public. These approaches have been deemed costly and possibly unsafe, because stacking containers on top of one another puts so much weight on the bottom drums. The Mullers say it’s much cheaper and safer to drill horizontal tunnels, and to do so in shale. They can fit the typical waste canisters (each 1 foot in diameter and 14 feet long) quickly and safely into shale tunnels, they say, given advances in fracking equipment. “Drilling the holes takes a couple weeks at most,” says Elizabeth…

The elder Muller first made his name dealing with radiation much farther away. As a professor at the University of California at Berkeley and senior scientist at the Lawrence Berkeley National Laboratory, Richard did that pioneering research on dark energy and cosmic radiation, including work on projects that eventually earned Nobel Prizes. After he and Elizabeth co-founded Berkeley Earth, a nonprofit that measures global temperature and climate change, he went from being one of the most prominent global warming doubters to one of the loudest voices confirming that climate change is real and caused by humans.

The idea for Deep Isolation grew out of the climate change work. Richard and Elizabeth are convinced that shifting China from coal to natural gas should be a priority, and when their effort to form a gas fracking venture in that country bogged down, they applied their newfound knowledge of drilling techniques to nuclear energy. The Mullers argue that the world must increase its use of nuclear energy to slow climate change and say solving the waste problem would encourage adoption.
