  The Integrated Waste Management program under the Office of Nuclear Energy is
planning for the future transportation, storage, and eventual disposal of spent
nuclear fuel and high-level radioactive waste from nuclear power plant and
waste custodian sites across the United States. To better enable informed
decision-making regarding the back end of the nuclear fuel cycle, the IWM
program has been sponsoring the development and application of system analysis
tools capable of analyzing various options for managing SNF and HLW. With these
tools, integrated waste management system architecture analyses are being
conducted to support the future deployment of a comprehensive nuclear waste
management system that considers all major back-end aspects of the nuclear fuel
cycle i.e., transportation, storage, and disposal. System analyses and
assessments typically use these modeling and simulation tools to investigate
implications of changes in various assumptions and parameters such as
acceptance rates, receipt logic, facility capacities and capabilities, use of
standardized canisters, start and stop dates of facilities, etc.
