when i say vinegar destroys battery corrosion i mean like this

The rusting mechanism and losing non-chrome cogs (versus the need to rotate your wheel to gain engineers back in hand and/or activate machines) is so good. It’s what keeps #Corrosion coming back to the table. #BoardGames #Brettspiel @brettspiele

Random equipment repair tip of the day: PB Blaster and patience is all you need, usually (though, a hammer in the right place can help). #corrosion #bolts

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."

After getting the #Commodore #C64 and #C128 running again, the next device to repair is the #C1571.
It had #corrosion and #rust on the main board and the power supply is beyond repairworthiness. I'd replace the latter with a #meanwell RD-35 with 5 and 12 volt output.
One #diode was rusty, a few traces needed #cleaning and five #resistor looked bad. Hope the black hybrid chip is still okay.
Sadly, the lower read head seems to be broken, my work might've been in vain.
