Radioactive Waste Storage in Boreholes

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. Read on for more info. (Diagram by IAEA)

Geotechnical engineers who encounter MSE retaining walls or Mechanically Stabilzed Earth Walls are undoubtedly familiar with the FHWA NHI manual on “Mechanically Stabilized Earth Walls and Reinforced Soil Slopes”. This manual, along with the NCMA manual that is used for non-transportation projects, is virtually the bible for MSE wall design. In late summer/early fall of 2009, a revised version of this manual will hit the streets. Read on for more details.

Landslide Closes SR 14 in Utah

Landslide blocks SR 14 east of Cedar City, UtahA large landslide has closed SR 14 east of Cedar City, Utah. UDOT expects that the road will be closed for up to 2 weeks for cleanup and to ensure that the slope is safe. Boulders up to an estimated 20 tons are now blocking the road and will likely need to be blasted down to a smaller size. A UDOT spokesman interviewed on the video shown after the break estimate the size of the slide at 700 to 800-ft long and 10 to 12-ft thick.

Oregon Landslide News and Map

Oregon man laments losing his house to fire after a landslide knocked it off its foundationThis is definitely the season for landslides, mudslides, debris flows and other mayhem in Oregon and elsewhere in the pacific northwest.

Having a hard time keeping up with it all, I decided to try something new. Click through to see a map of automatically updated landslide news in Oregon. Lets call it a Beta…so we’ll see if it works out. If it does, maybe I’ll try something similar for other areas or other items that tend to make it into the news.
