New Nuclear Waste Recycling Technology Discovered by Notre Dame Researchers

nuclear waste New Nuclear Waste Recycling Technology Discovered by Notre Dame ResearchersMaybe the folks at Fukushima should hear about this, or more precisely those handling the recovery process, which is far from over: as the latest discovery in the field, the Notre Dame Thorium Borate-1 (NDTB-1) is apparently just what you need to clean up a radioactive mess.

Although the current trend is all for clean energy from renewable sources, there are still countries which rely on nuclear energy for their needs. Thus, there are more than 436 nuclear power plants in 30 countries and the radionuclide technetium (99Tc) is there at almost every site. Only last year there were 305 metric tons of 99Tc collected for a period of 67 years. So yes, radioactive ions are something to be dealt with.

In consequence, a team of researchers from the University of Notre Dame, coordinated by professor of civil engineering and geological sciences Thomas E. Albrecht-Schmitt, claim this crystalline compound, in a modified form, can be used to “eat out” the radioactive ions from nuclear waste streams. Their framework of channels and cages of very small pores makes possible an exchange between anions with a environmental contaminants like chromate and pertechnetate.

However, what does one do with the ions afterwards? The answer is they can be secured and recycled as a material. Apparently, the success rate of the NDTB-1 crystals is fairy high, “curing” 96$ of the amount of 99Tc. Check out the Advanced Functional Materials if you want to find out more, but it’s a pretty nice knowing that you have a solution in emergency cases.

All technology remove the Radioactive element from disaster sites and beneficial technique but i m worried about that what after Bioaccumulatin of Radionuclides with high half life such as Sr-90/Cs-134/137,and which place that radiactive contaminated Algae dispose off,Disposal again a problem ,But in my opinion Plasma,and Bose -Eienstine Condensate help ful in Management of Radioactive waste and Other Hazardous waste.

so, if i understand correctly, this new material sorts and thereby concentrates one particular radioactive compound in the waste stream, but does not actually break it down, right? if so, that would certainly make handling more efficient. still, seems like there would still be that pesky long term security and storage issue -- the 800 lb gorilla in any room where people are talking about nuclear energy.
