Public comment extended to September 1st!

Environmental groups criticize #Hanford #nuclear waste cleanup plan

"A new agreement on plans for cleaning up nuclear waste at the Hanford site in #WashingtonState is receiving pushback from #environmental groups.

"Public comment was originally scheduled to close at the beginning of August but has been extended to Sept. 1 for the Tri-Party Agreement between the U-S Energy Department, Environmental Protection Agency and Washington Department of Ecology.

"Simone Anter, staff attorney and Hanford program director for the nonprofit #ColumbiaRiverkeeper, said the new agreement means changes to the cleanup efforts including how and where the Hanford #NuclearWaste is stored.

"'If new proposals are coming out to ship either grouted or liquid nuclear waste across the region, communities deserve to know that and deserve to have a voice and deserve to be engaged,' Anter contended.

"The agreement for dealing with 177 underground storage tanks at Hanford took four years of closed door negotiations. Columbia #Riverkeeper and other environmental groups worry the new agreement opens the door for a storage method other than #vitrification, which is used to turn high-level waste into glass.

"Anter noted #TribalNations in the region were not consulted about the proposal. She stressed even if they could not be part of the agreement, the agencies should have been considered before it was presented to the public.

"'#Tribal nations are not members of the public. They are government entities and should have been treated as such,' Anter pointed out.

"Anter added members of the public can play a big role in how the 56 million gallons of nuclear waste at Hanford are handled.

"'It's really important that all these cleanup decisions put human health, the #ColumbiaRiver and the environment first,' Anter asserted. 'I think public comments play an enormous role in reminding the #TPA agencies about this."

As ocean temperatures rise, more and more coral reefs are put at risk of extinction.

A collaborative research team have developed a method of isochoric vitrification that allows coral to be cryopreserved without harm and then revived with a prepared solution, allowing them to be moved to increase biodiversity and genetic resistance to increasing temperatures.

.> What glass compositions will lead to the highest uptake of nuclear waste? How suited are those glasses to vitrification? And how well will they resist corrosion after being interned for eons in a repository environment?... the exact formulation of the glass, or glasses, is still under investigation...
.> The study uncovered a previously unknown corrosion mechanism involving dissimilar materials in close contact; some researchers say this process could decrease the durability of glassy nuclear waste... the results suggest that less than 1 in 10,000 of the waste packages proposed for storage at Yucca Mountain would fail in 150,000 years.

Condemned? 🙅 No, it's VITRIFIED! ✨👍

#Portal #Portal2 #CaveJohnson #Vitrification #Vitrified

Time for some Portal 2 lore.

Cave Johnson had to condemn a lot of his old Aperture Science test chambers due to safety regulations and how these labs were discovered to be in violation. You'll see signs like "KEEP OUT", "CONTAMINATION AREA", "DO NOT ENTER", "EXPERIMENT DISCONTINUED", "CONDEMNED", "DANGER", "COSMIC RAY SPALLATION ELEMENTS". Cave Johnson most likely didn't prefer these scary blocks of text. To mitigate, he came up with simple and elegant "VITRIFIED". It is unknown whether chambers were really vitrified or just closed off for the better times, but the word itself fits regulations perfectly, while giving off this mysterious vibe.

Not that: "KEEP OUT", "CONDEMNED", etc.
But this: "VITRIFIED". ✨✨✨
