NRC License Disposal Area

 

Currently, work at the NDA involves the installation of a slurry wall to reduce ground water inflitration. To install the slurry wall a trench is being excavated along the west and south sides of the NDA. The trench trench is being backfilled with a mixed slurry of soil and bentonite clay, which has elastic properties that make it nearly impermeable to water. A membrane cover will be placed over the NDA later this year, to further reduce runoff infiltration. In the photo to the right, a bag of bentonite clay is being emptied into a portable mixer to make the slurry.

Bentonite Mixing Pit

This picture shows the soil bentonite mixing pit where a tracked excavator assists in the mixing process of bentonite slurry and excavated soil and then removes the soil bentonite slurry mix and puts it into the bed of a transport truck. Preparation for the slump test on the soil bentonite slurry mix is in progress at the near side of the mixing pit. Behind the pit you can see the bed of a truck loaded with soil bentonite slurry mix.
