The nation needs to establish a formal, "risk-informed" approach to decide what types and amounts of radioactive waste at U.S. Department of Energy sites should be buried or left in place rather than shipped to a geological repository, such as the one proposed for Yucca Mountain, Nev., says a new report from the National Academies’ National Research Council.
"Given the controversy surrounding this issue and the reality that not all of the waste will or can be recovered and disposed of off-site, the country needs a structured, well-thought-out way to determine which wastes can stay," said David E. Daniel, chair of the committee that wrote the report and dean, College of Engineering, University of Illinois, Urbana-Champaign. "Information about the relative risks posed by various disposal options is vital to the decision-making process, and that information must be developed in a manner the public can trust."
The committee did not identify specific wastes that should be approved for alternative disposal. It did find, however, that it is "technically impractical and unnecessary" to remove every last gram of high-level radioactive waste now stored in steel tanks at DOE sites in South Carolina, Washington, and Idaho. Some transuranic waste currently buried at these sites -- which consists of contaminated tools, clothing, and other debris -- may not need to be removed either. The committee did not comment on how waste remaining on-site should be disposed of.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
