ISOCELL provides complete containment, isolation, and mobilization of mixed or high level radioactive waste, including exploded or unexploded ordances, rusting drums, or gas cylinders. The ISOCELL process was specifically designed to protect the health and safety of workers, the environment, and the public. The ISOCELL process involves the installation of freeze pipes around hazardous substances or an area of subsurface contamination with lifting brackets inserted before freeze down. Standard installations provide frustrum shaped soil parcels 8'x 8'x 10'in size, but can be sized up to 20' to 30' in length. Parcel size is determined by soil conditions, mitigation specifications, and transportation requirements where required. To lift the blocks, their vertical boundaries are loosened by selective thawing. Thermal influencing pipes installed before freezedown create a thinly thawed boundary between a frozen parcel and the surrounding soil, allowing separation. Once the initial lift has been accomplished, the boundary layer is refrozen, and parcels are mobilized according to one of RKK's site specific options. Once extracted, blocks can be transported offsite or processed onsite through vitrification, incineration, or another acceptable remediation process.
The primary benefit of the ISOCELL system is both exposure to airborne contaminants, and the mixing of wastes during the recovery process, is eliminated. Waste mixing is a factor of great concern when dealing with unknown hazardous substances or plutonium waste, the contact of two or more parts in sufficient quantities could attain a critical state.
Field Tested and verified, ready for immediate implementation.

ISOCELL provides a tremendous cost reduction to clients, especially in mixed waste sites. Present cleanup practices are unable to separate various waste types, resulting in a cleanup cost based on the most hazardous material present. A parcel of hazardous substances stabilized and mobilized by the ISOCELL process can be scanned and inventoried, providing waste classification. This equates to baseline volume waste reduction and a decreased site cleanup cost. ISOCELL is the only method permitting the proper technology and/or mitigation technique to be applied to the various hazardous substance classifications at any given site. ISOCELL engineering is specific to the hazardous substance being mobilized at a site, with designs incorporating ISO 14000 standards.
