Governments rapidly classify secret most matters categorised as Nuclear. Putting such stuff on an open global blockchain is an impossible dream.
I can see the logic in that in regards to nuclear, but nuclear waste is that defined as a big open secret?
Oftentimes, the spent nuclear fuel can be reprocessed as nuclear weapons grade material. Japan with it's huge stockpile of reactor-generated Plutonium is a good example. At least Japan is open about these matters, so we know the exact quantity of waste and Plutonium in their storage.
But several other nations are much less open, because it might be possible to estimate their total supply of weapons grade material based on the amount of nuclear waste. Some other governments use this as a useful cloak to hide their inefficiencies or deficiencies. Nuclear waste is, in the end, a non-productive expense that they seek to avoid.
Thanks for telling me that.. I just assumed that there would be some transparency in this regard. I was recently reading an article that they are now suspecting the copper barrels they will store the nuclear waste in Onkalo spent nuclear fuel repository, will decay at a quicker rate than they first assumed. So I can only imagine that will eventually leak into the water tables... which is a scary thought.. but like the powers at be today, thats not my problem for anybody in 1,000+ years!
QUOTE“Copper corrosion is much faster than they”—Posiva and SKB—“claim,” Peter Szakálos, a corrosion researcher at the Royal Institute of Technology in Sweden, told me over Skype this June. “SKB has stated in its document that less than one copper canister will fail in one million years. But if you look at the corrosion rate that happens in groundwater, we say the first canister will fail in 100 years and the majority will fail in 1,000 years.” The reports from Posiva and SKB’s laboratories are alarming, Szakálos added. “Their tests didn’t match their theoretical predictions.”
