Not to mention all the #WaterConsumption! There are plans to restart aging nuclear reactor as well as untested SMR reactors! Will #AI’s huge energy demands spur a #nuclear renaissance?
By Davide Castelvecchi
25 October 2024Do small modular reactors carry extra risks?
"In some cases, small modular reactors 'could actually push nuclear power in a more dangerous direction', says #EdwinLyman. 'Advanced isn’t always better.'
"In particular, Lyman points out that the pebble-bed designs drawn up by #XEnergy and #Kairos would rely on high-assay low-enriched #uranium (#HALEU), which comprises 10–20% uranium-235 — compared with the 5% enrichment level required by most existing reactors (and by #NuScale’s reactor). HALEU is still classified as low-enrichment fuel (as opposed to the highly enriched uranium used to make nuclear bombs), but that distinction is misleading, Lyman says. In June, he and his collaborators — including physicist Richard Garwin, who led the design of the first hydrogen bomb — warned in a Science article that a bomb could be built with a few hundred kilograms of HALEU, with no need for further enrichment.
"Smaller reactors are also likely to produce more nuclear waste and to use fuel less efficiently, according to work reported in 2022 by Macfarlane and her collaborators. In a full-size reactor, most of the neutrons produced by the splitting of uranium travel through a large volume of fuel, meaning that they have a high probability of hitting another nucleus, rather than colliding with the walls of the reactor vessel or escaping into the surrounding building. 'When you shrink the reactor, there’s less material in there, so you will have more neutron leakage,' Macfarlane says. These rogue neutrons can be absorbed by other atomic nuclei — which would then themselves become radioactive."

What?!! #NEI is actually publishing something NEGATIVE about #NuclearEnergy? That doesn't happen very often!
US #NRC proposes fining #Urenco USA
Staff writer, April 7, 2023
"The US Nuclear Regulatory Commission (NRC) has proposed a $70,000 civil penalty for Urenco USA for two violations of agency requirements related to improperly implementing safety controls at its #EuniceNewMexico, #UraniumEnrichment plant.
"The first violation occurred during a March 2022 event when plant staff found three construction vehicles parked near a building that handles #UraniumHexafluoride [#UF6] without physical barriers in place. The company notified NRC as required and the agency launched a special inspection in response and documented its findings.
"Specifically, the company did not take enough precautions to prevent a potential accident sequence involving construction vehicles damaging the facility or the uranium hexafluoride inside – increasing the risk to plant workers and the public. Urenco USA was notified of the apparent violations in December 2022 and in a written response admitted the violations, and discussed plans for corrective actions. NRC said it had reviewed Urenco USA’s response and determined that, while the incidents did not result in the release of radioactive material, the potential safety consequences warrant the proposed fine. The company has 30 days to pay the proposed penalty or contest it. The NRC will consider any response from the company before making a final determination on the matter."

So, #Terrapower and other #HALEU energy projects are being touted as "carbon-free". But alas, a lot of energy is spent digging, milling, transporting and enriching #Uranium -- and there's still no place to permanently store #NuclearWaste.
And #NewNuclear is far from CLEAN -- ask the residents of #PiketonOhio -- who are still dealing with #contamination from when the uranium enrichment plant was operating before!
Radioactive cylinders abound at former Portsmouth Gaseous Diffusion Plant site
by The Guardian
August 7, 2024
PIKETON, Ohio – "The site of the former Portsmouth Gaseous Diffusion Plant in Piketon is home to a significant number of radioactive cylinders, posing ongoing environmental and health risks. As of 2022, there are a total of 20,570 uranium hexafluoride (#UF6) cylinders at the site, including 1,879 low-enriched uranium (LEU) cylinders, 18,206 depleted uranium cylinders, and 385 empty cylinders.
"These cylinders, which have been stored in the open for decades, are known to be among the highest sources of #radioactive contamination at the entire plant site. The U.S. Department of Energy [#DOE] has repeatedly reported the #hazardous conditions associated with these cylinder yards.
Chemical Reaction and #Corrosion
"UF6 is highly reactive with moisture, forming uranyl fluoride (UO2F2) and hydrogen fluoride (HF). Both compounds are extremely corrosive and toxic. HF can lead to severe corrosion of the cylinder walls, potentially resulting in leaks and the release of hazardous materials. The environmental and health impacts of these compounds are severe; HF can cause respiratory issues, skin burns, and eye damage, while UO2F2 can lead to kidney damage and other serious health problems.
Historical Accidents
"The potential risks are not hypothetical. In 1978, a major incident occurred when a UF6 cylinder ruptured, releasing over 20,000 pounds of uranium hexafluoride into the atmosphere. Over the years, there have been dozens of such accidental releases, exacerbating the environmental and health risks associated with the site."
