Spent Fuel stored in World Regions
Through CY 2003
5 International Atomic Energy Agency
Trends
• About 10 000 t (HM)/a spent fuel are unloaded from nuclear power reactors worldwide;
• 7 500 t HM need to be stored (after accounting for reprocessed fuel);
• Most spent fuel in wet storage, with dry storage use increasing;
• Estimated annual discharge amount will increase to some 11 500 t HM/a by 2010;
• The global storage capacity currently available and under construction would accommodate spent fuel arisings through 2015;
6 International Atomic Energy Agency
Trends – cont’d
• Sufficient fuel storage capacity on a global basis;• National situations differ and may require urgent
attention;• Use of MOX and higher enrichment/burnup lead to
higher decay heat levels• Long term storage becoming a progressive reality…all
national programmes anticipate longer storage durations (up to 100 years and even beyond);
• Long term storage of spent fuel requires social stability to maintain institutional control.
7 International Atomic Energy Agency
Challenges
• Advanced technologies for assuring longer time spans;• License extensions for existing facilities;• Increasing awareness of the need to involve society in
decision processes;• Institutional frameworks and arrangements that are
sustainable over the long term;• Preservation of information, expertise and knowledge.
8 International Atomic Energy Agency

•180 participants in three sequential sessions on advanced concepts, waste management, and research reactors…12 detailed presentations plus panel comments and discussions.•Scientific Forum session summaries can be accessed at http://www.iaea.org/NewsCenter/News/2004/sf_session.html•Presentations and synopses can also be accessed on the Agency’s website
9 International Atomic Energy Agency
IAEA 2004 Scientific Forum-cont’d• Dr. Les Shephard, SNL, chair of session two (waste and spent fuel management issues) noted “a wealth of success and experience” with spent fuel management ,and suggested a systems approach based onstandardized designs and enhanced multinational cooperation;
•Dr. Bernard Bigot, CEA, chair of the Forum noted that safe, robust storage technologies provide system flexibility while addressinglonger term options/issues, and that international communication and sharing progress to date are important in addressing these issues.

REPROCESSING AS AN OPTION FOR SFMREPROCESSING AS AN OPTION FOR SFM
• EVOLUTION OF PURPOSE• PAST : The classical option for spent fuel management (to
recover fissile materials for recycle as MOX, especially in FBR)• PRESENT: A fraction of spent fuel inventory recycled to thermal
reactors (mainly in LWR)• FUTURE : Anticipation for innovative nuclear systems, P&T,etc
• INDUSTRIAL MATURITY• Currently, the only industrially available option (~1/3 of global
inventory of spent fuel being reprocessed)• Technical and/or infrastructural base for future applications to
other futuristic options (i.e., P&T)
33 International Atomic Energy Agency
DIVERSIFICATION OF CONCEPTDIVERSIFICATION OF CONCEPT• DIRECT REUSE (Without Pu Separation)
• Spent LWR fuel directly refabricated into HWR fuel (DUPIC)• Spent LWR fuel refabricated into LWR fuel by adding EU (AIROX)
• PARTITIONING AND TRANSMUTATION (P&T)• Reduce lifetime of MA or FP for waste management purpose• Applications of industrial reprocessing technology +R&D
• PROCESSING FOR STORAGE/DISPOSAL• Destructive packaging for disposal (cutting, melting.etc)

COMMON ISSUES TO ALL OPTIONSCOMMON ISSUES TO ALL OPTIONS
• SUSTAINABILITY• Cost-effective • Proliferation-resistant• Environmentally friendly
• INSTITUTIONAL ISSUES• Political/economical/social stability• Information management
• REGIONALIZATION / INTERNATIONALIZATION• Win-win strategy (especially beneficial for small scale partners)• Difficulty of finding host to the site(s) of facilities
35 International Atomic Energy Agency
REGIONALIZATION / REGIONALIZATION / INTERNATIONALIZATIONINTERNATIONALIZATION
• NATIONAL BASIS OF SPENT FUEL MANAGEMENT• Most spent fuel management based on national level initiative• Some regionalization succeeded (EURATOM, Reprocessing services in
Western and Eastern Europe )• Most other regional/international proposals failed in the past
• BENEFITS OF LARGER SCALE APPROACH• Economy of scale ( good for small nuclear programmes) • Win-win partnership for resources utilization, confidence, etc)
• OUTSTANDING ISSUES• Finding interested customers, as well as host for the centre• Breakthrough in commercial terms (‘cradle to grave service’?)

STORAGE TECHNOLOGYSTORAGE TECHNOLOGY• STORAGE EXPERIENCE WORLDWIDE
• Dry Storage : A Couple of Decades (Several Options)• Wet Storage : Over 4 Decades (All in Water pools)
• STATUS• Majority of spent fuel still stored in water pools (historical reason)• Dry storage options ( metal cask, concrete canister, vault) have
recently been becoming a very popular choice ( especially dual purpose casks )
• MERITS OF DRY STORAGE• Flexible Construction and Cost-effective O&M• Possibility for Long-term Storage
42 International Atomic Energy Agency
Trends in AFR Storage• AFR storage demand continues to grow ensuing with
long term dry storage provisions• Excess capacities for spent fuel storage will decrease in
the future with increasing preference of dry modular storage systems
• Supply side of the spent fuel storage has well matured and competitive services available on international market
• Selection of option involves various criteria, including economics, to be considered in the bid evaluation and selection.
• Public involvement is becoming an important issue
