CONTAMINATION CONTROL DURING IN SITU JET GROUTING FOR APPLICATION IN A BURIED TRANSURANIC WASTE SITE

PDF Version Also Available for Download.

Description

Engineers at the Idaho National Engineering and Environmental Laboratory (INEEL) have developed means of contamination control associated with jet-grouting buried radioactive mixed waste sites. Finely divided plutonium/americium oxide particulate can escape as the drill stem of the jet-grouting apparatus exits a waste deposit in preparation for insertion in another injection hole. In studying various options for controlling this potential contamination, engineers found that an elaborate glovebox/drill string shroud system prevents contaminants from spreading. Researchers jet-grouted a pit with nonradioactive tracers to simulate the movement of plutonium fines during an actual application. Data from the testing indicate that the grout immobilizes ... continued below

Data from the testing indicate that the grout immobilizes the tracer material by locking it up in particles large enough to resist aerosolization.
