Off-Site source recovery project expansion

The mission of the Off-Site Source Recovery (OSR) Project at Los Alamos National Laboratory was expanded in 2004 by its program sponsor (Reference 1), the Office of Global Threat Reduction (NA-21), National Nuclear Security Administration (NNSA). The expansion increased the number of isotopes handled by the OSR Project to at least ten and removed the restriction that the project was only to handle Greater-Than-Class-C (GTCC) sealed sources. A further expansion also has occurred enabling the OSR Project to repatriate at-risk US-origin material from other countries on a case-by-case basis. This paper provides an update of the successes of the OSR Project in terms of its previously defined mission to recover predominantly actinide bearing sealed sources, and presents a summary of the additional nuclides, management plans for recovery, storage and disposal, and priorities and successes. Partnerships with other agencies to address associated problems are also discussed. (authors)
