Partnership", which also served as the source for a M-TSD section of a "GNEP Deployment Strategy" document. One of several versions of this report is attached as an appendix to this FY-07 Summary.• Cooperation with a new "Integrated Waste Management Strategy" effort that developed a more extensive strategy document and a waste management baseline report. At the close of FY-07, this IWMS and the Systems M-TSD are being more closely coupled.• Coordination of analyses began with a newly formed Waste Form Campaign, which will conduct R&D and analysis on disposal forms for GNEP waste streams. • Reviews were conducted of the AFCF 30% conceptual design, and of draft material for the Programmatic Environmental Impact Statement to assure consistency in material management planning across GNEP project elements.• International partnerships began under GNEP, including a US-Japan working group on waste management R&D.• Technical analyses (summarized below) were conducted and reported by:o ANL -SNF processing and recycle requirement for repository benefit o SNL -Transportation cooling times for burner fuels o LLNL -Survey of available packaging o UN-R -Thermal modeling and testing of SNF shipping casks As FY-08 approaches, the M-TSD team will continue to add expertise as needed, integrate with IWMS, and prepare technical bases to support mid-year decisions regarding the programmatic path forward. 2 Material Transportation Storage and Disposal Analysis SummariesSeveral technical analyses conducted during FY-07 are summarized below, with reference to more complete reports (where available). Summary of FY-07 Repository Benefit Analyses (ANL)An important long-term objective of GNEP is to provide improvement in the long-term management of radioactive waste. Through fast reactor recycle of actinides, it is possible to generate far less waste, and potentially easier waste to manage, than with the current once-thru fuel cycle. However, the precise extent and value of these benefits are complex and difficult to quantify. At the same time, advanced fuel cycles may create additional product and waste streams that require interim storage or extended storage.The primary analysis of repository benefits is conducted by ANL, with assessment of the impacts of reduced decay heat on potential repository capacity, and reduced long-lived radionuclides on potential repository isolation performance. The primary report for the year was completed in Fast Reactor Recycle and Impact on Geologic DisposalPrevious work has established the relationship between the processing efficiencies of spent LWR fuel, as represented by spent PWR fuel, and the potential increase in repository utilization for the resulting processing waste. A study 1 was completed to determine a similar relationship for the waste from processing spent fast reactor fuel. The wastes from the combination of LWRs and fast reactors as would be deployed with the GNEP approach were then examined.The conclusions of that study are:• The higher transuranic content of fast reactor fuel results in...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
