Boulder, Colorado, USA — The scientific community can now take a long-awaited look at the research behind the selection of Yucca Mountain, Nevada, as the nation’s high-level radioactive waste repository.
On the Radwaste blog by Geoff, I read about Borehole Disposal of Sealed Radioactive Sources or BOSS. This technology, which is explained by the International Atomic Energy Agency (IAEA) consists of disposal of smaller quantities of radioactive waste in specially engineered boreholes 30 to 100-m (approx. 100 to 330-ft) deep in suitable geologic media.

A pilot study is about to be undertaken by the Pacific Northwest National Laboratory to study the possibility of CO2 sequestration in deep basalt formations throughout the West and Northwest. The study will involve injecting 3,000 to 5,000 tons of liquid CO2 at a depth of between 3,000 and 4,000-ft. The team hopes that mineralization will gradually transform the CO2 and basalt into limestone. The total cost of the pilot study is approximately $10 million and is funded primarily by the U.S. Department of Energy.
