Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from September through December 2022.
But first:
Taking waste into outer space would require quite large vehicles, like the Saturn 5 rocket shown here carrying the Apollo 14 crew to the moon. A huge fireball forms underneath the rocket . . . hmm, would that be wise? (Source: NASA)
Nuclear waste disposal presents a frustrating problem far beyond its actual danger. No one has ever been harmed by commercial nuclear waste, and no one is likely to ever be harmed.
But we do have to find a final resting place for nuclear waste as it decays away back to the levels of the ore from which it came.
There are several types of nuclear waste: low-level waste (LLW), intermediate-level waste (ILW), transuranic waste (TRU; referring only to bomb waste without a lot of cesium-137 or strontium-90), high-level waste (HLW; also only bomb waste), and spent nuclear fuel (SNF; from commercial power plants only). In the United States, TRU waste, HLW, and SNF require deep geologic disposal by law.
Nuclear energy offers a pairing of high capacity factors and low carbon emissions unrivaled by other power sources, and advanced reactors and small modular reactors (SMRs) hold promise to deliver that power with even more efficiency and versatility. Researchers in the public and private sectors, backed by government funding through programs like the Department of Energy’s Advanced Reactor Demonstration Program and Advanced Research Projects Agency–Energy (ARPA-E), are bringing that promise closer to fulfillment by engineering solutions to open questions about advanced reactor materials and fuel cycles.
On June 2, Nuclear Newswire published a letter from Jose Reyes, chief technology officer at small modular reactor developer NuScale Power, to May R. Berenbaum, editor-in-chief of Proceedings of the National Academy of Sciences, regarding a research article published by PNAS two days previous. The article, “Nuclear waste from small modular reactors,” has grabbed more than a few headlines for its claim that SMRs will actually generate more nuclear waste than a standard large pressurized water reactor.
A Stanford University–led research article on small modular reactors published Tuesday in Proceedings of the National Academy of Sciences (PNAS) is not sitting well with SMR developers or, for that matter, with much of the largely pro-SMR nuclear community.
