Radioactive Wastes in Landfills

TA14.1 Containment for Landfills Jennifer Nelson, Tom Burford, Steve Dwyer, Brian Dwyer --- Sandia Ntl. Labs., PO Box 5800, MS 0719, Albuquerque, NM 87185-0719, (jenelso@sandia.gov)

Technologies that can be integrated into new or existing landfill¨ closures to contain contaminant migration in arid environments are¨ evaluated. They include cover demonstrations, design criteria for¨ covers, an in-situ membrane monitoring system, subsurface barrier¨ emplacements and monitoring to verify that barrier integrity is¨ highlighted.

TA14.2 Development of New Technologies for Remediation of DoE Radioactive Waste Landfills George Schneider --- US DoE Idaho Operations Office, 850 Energy Dr., MS 1219, Idaho Falls, ID 83402 , (schneigj@inel.gov)

The US has 3.1 million cubic meters of buried waste and even more in¨ contaminated soils that must be remediated. THe DoE has implemented¨ a system analysis-based methodology to identify specific needs and¨ performance requirements, such as cost and risk, for new¨ technologies to guide their selection and development.

TA14.3 Real-World Applications Bridging Developers & Users Paul J. Pettit, Sharon Fauver, Rod Warner --- FERMCO, MS81-2, PO Box 538704, Cincinnati, OH 45253 ,

Described are details of the processes used for cooperation between¨ stakeholders, regulators, developers of technology and users engaged¨ in the pursuit of accelerated remediation. The focus is on the¨ Fernald experience in overcoming barriers with successful examples¨ of particular innovative technologies supportive of the 10-year¨ cleanup of the site.
