Many years ago we visited Hanford while on vacation in the Northwest, as a souvenir they gave us a brown glass marble, to show what they were doing with the waste, it wasn’t radioactive, but just a sign of where they were going… And it’s all those marbles that were going deep, somewhere, maybe NV or at least further from the Columbia River… Old friend live in Bridgeport, WA, near the Chief Joseph Dam, after WeCo, he took over his Dad’s tavern and also worked for the Corps at the Dam… The Columbia provides a lot of power to the NW…
I have a friend working in the Hanford plant. She is an artist when she is not working. It is endless bureaucratic work. She works scientifically with chemicals. Whatever that should mean. She is my age, 60, and just got an office. She wants to avoid the younger folks, the gossip etc…but cant. Office work in the middle of a complete disaster.
Hey, we have to keep up with the Russkies, and they are way ahead on this one, thank you Chernobyl. Better exterminate all with professional knowledge of sequestering nuclear waste so we can surge into the lead.
In the US nimby is still a problem. We know how to store nuclear waste safely; we can’t agree where. Some countries in Europe are better at it. And reprocessing used fuel for longer utility makes sense to me.
I worked on the high level and low/med level radioactive waste vitrification facilities at Hanford from 1997-2005 and before that at the vitrification facility at Savannah River Site between 1985-1990. The brown glass marbles are just a non-radioactive sample of vitrification of nuclear waste form of encapsulation. Actually the radioactive waste and glass are melted and poured into stainless steel canisters for storage and eventual placement in a geological high level waste repository.
People discussing nuclear waste often get confused in the levels of radioactivity, the storage methods used for each level of waste, and the sources of the waste:
Radioactive waste streams:
nuclear power plants
nuclear weapons facilities
uranium mining and processing facilities
Medical and industrial wastes
Levels of waste:
Low level waste
Medium level
Transuranic waste
High level waste (commercial nuclear reactor fuel rods, nuclear weapons processing fluids and solids)
Waste storage methods:
Low level waste in 55 gallon barrels in landfills and shallow caverns at designated sites. Includes contaminated clothing, tools, equipment, processing fluids and solids.
Medium level waste: Ion exchange resins and other processing wastes that need more protection than low level wastes.
Transuranic waste (Plutonium and other such wastes)
High level waste from nuclear power plants is first cooled down in large fuel pools, then transferred to dry casks, and eventually stored in deep geological repositories for thousands of years.
High level waste from nuclear weapons programs have been stored in huge double shell tanks at Hanford, Savannah River, and other DOE sites. Some of these wastes have been virified and placed into stainless steel canisters for temporary storage at the DOE sites until eventually stored in deep geological repositories for thousands of years.
So Germany’s storage of low and medium level waste in potash mine is no worse than landfill burials in the US. What all countries are searching for is where to bury their high level radioactive waste from commercial reactors and from weapons
Finland has decided to store their high level nuclear waste (spent fuel) in deep under ground as explained in the link below. This is a cost, safety and nimby problem.
For those that don’t know. It isn’t quite that simple. The spent fuel rods continue to produce decay heat so they have to be ~continuously cooled for 5 - 10 years, sometimes even longer, as the level of heat production decays away to a low enough level that it can be safely stored in the dry casks.
US problem is that Yucca Mountain was a political choice the did not work out because of water intrusion problem after years of research costing $ billions. New funds need to be allocated. US is studying new locations for high level nuclear power and nuclear weapons waste.
Not Nimby, you all just were just pikers and didn’t want to pay Nevada to take it. Oh yeah 50 jobs, woohoo. Just what we needed. You want us to take your trash (Nevada does not have any nuclear plants and we already let you test your nuclear bombs) you really need to up the compensation.
This the project I worked on for many years as an Bechtel National, Inc. project engineering manager until I retired in 2005. We worked with several companies such as BNFL, Duratek, and many other nuclear engineering and construction companies. The project started in 1996 when BNFL and Bechtel National won the bid for this DOE project. Bechtel National was selected by DOE to be the lead contractor for the project in 2000 Bechtel National has been awarded a contract to work on the Waste Treatment and Immobilization Plant (WTP) at the Hanford Site in Washington state. This project involves treating and immobilizing radioactive waste using a process called vitrification. Bechtel has been involved in the project for many years, working on its design, construction, and commissioning.
The WTP uses vitrification, a process where radioactive waste is mixed with glass-forming materials, heated to high temperatures, and then poured into stainless steel containers for safe storage.
That is a good question. Texas has four nuclear reactors, they were one of the sites that came down to the last selection and they stuffed it down Nevada’s throat. Oh and George Bush the second was the President at the time. Awful convenient wasn’t it.
