Spent Fuel Management:
Current Situation
• At the end of 2018, 400+ kt (HM) had been
discharged from NPPs
• Of which about 270+ kt (HM) stored in facilities, either
at reactor (AR) sites or away from reactor (AFR) sites,
the remainder reprocessed
− The majority of SF is stored wet (~80%) in AR site storage facilities
− AR storage in some Member States is becoming saturated
• There are 151 AFR storage facilities in 27 countries of which ~80% are dry
• Some MSs (Canada, USA) have >30% of their spent fuel inventory in dry storage
On the Management of Spent Fuel…
Storage duration: a challenge
• Planned storage durations are increasing:
– In 1980s 20-50 years,
– In 1990s up to 100 years
– In 2000s 100+ years
• License renewal
• Confirming on-going spent fuel behaviour &
integrity
• Maintenance and inspection of Systems
Structures and Components (SSCs)
• Ageing management of deployed storage
systems (beyond design basis for most)
• TransportabilityYankee Rowe NPP (USA)
On the Management of Spent Fuel…
• Advanced reactors implementation
• Environment-friendly innovative fuel cycles:
– Fully closed (recycling valuable materials)
– Natural resources preservation
– Waste burden minimization
– Proliferation resistant
– Flexible to adapt to any policy evolution

CURRENT IAEA’S ACTIVITIES ON SPENT
FUEL MANAGEMENT
Scope of work SFM Team
• Storage (until ultimate
disposition)
• Reprocessing and recycling
current fleet
• Advanced Fuel Cycles for
Gen-IV
• Transportation of spent fuel
Towards sustainable, safe, secure and economic
long term storage of Spent Fuel
Coordinated Research Project on “Demonstrating Performance of Spent Fuel and Related
Storage System Components During Very Long Term Storage” (DEMO)
CRP No T13014 (2012-2016) Closed
• Overall Objective
– To support the technical basis for water reactor
SF dry storage as durations extend
– Specific research activities:• Stress Corrosion Cracking Mechanisms
• Concrete Systems Degradation
• Cladding Behaviour
• Bolted Closure Systems
• Gamma and Neutron Shielding
• System Demonstration (JPN and USA)
– 11 RAs and 7 RCs from 11 Member States
• Linked to Extended Storage Collaboration Programme (ESCP) International Sub-committee of
EPRI
On the Management of Spent Fuel…
Coordinated Research Project on “Spent Fuel Performance Assessment and Research” (SPAR IV)
CRP No T13016 (2016-2020) Active
• Series of coordinated research projects:
– BEhaviour of spent Fuel Assemblies in STorage (BEFAST I, II and III) and later
– Spent fuel Performance Assessment and Research (SPAR I, II, III and IV)
• Covering all power reactor fuels and
− MAGNOX, RBMK, WWER, AGR, BWR, PWR, HWR, PHWR
• Wet and Dry storage systems
• Spent fuel management strategies
• Cladding performance (hydride reorientation)
• Storage facility component degradation studies
• Drying and Dry to wet transfer
• Thermal modelling
• Spent fuel condition on transfer to the next step in the BEFC
• 7 RAs and 4 RCs from 10 MSs

Coordinated Research Project on “Ageing Management Programmes for Dry Storage Systems”
CRP No T21028 (2016-2020) Active
– 5 RAs and 1 RC from 4 MSs, observers from 6 MSs
• Background
Challenge: concern with respect to the transportation of storage packages after extended storage
Ageing Management Programmes (AMP) aim at timely detection and control of age-related degradation and other conditions that
may jeopardize future handling and transport, contributing to ensuring safety along time
AMP is a requirement in the new SSR-6
• CRP Overall Objective
– To develop the technical basis and methodology to enable guidance to be provided to Member States on how to generate an ageing
management programme for spent fuel dry storage systems
• Scope
– All dry storage systems for power reactor spent fuel
• Specific activities on
– National regulations (License renewal for extended storage)
– Process for generating am AMP (generic flowchart)
– Identification of SSC (Categorization)
– Technical underpinning (SF, Materials, Systems)
– Operating experience (DPCS, MVDS, Silos)

economic long term storage of Spent Fuel

Activities on SF storage
Spent Fuel Storage Guide
• Guidebook on Spent Fuel Storage (IAEA TRS 240, 1991)
− Covers all aspects of storage
− Will highlight the evolution of SF storage and the fact that
storage lifetimes are much longer than anticipated in 1991
Management of SF at Shutdown Reactors
• Covers planned and unplanned reactor shut downs
– E.g. for phase out of nuclear energy or economical reasons
• Technical Meeting on premature shutdown of nuclear power
plants held June 2018
• Site visit to Oyster Creek NPP with DOE May 2019
• TECDOC currently in production
Activities on Integrated Approaches
Integrated approaches to the back end of the fuel cycle
• There is a need to look at the back end of the fuel cycle in a fully integrated manner including items such as retrievability, transportation, storage, recycling and disposal;
• Publication IAEA-TECDOC-1774,based on material gathered prior to 2011;
• TM held July 2018 and updated TECDOC now in preparation.
