What is Spent Fuel Storage?
Spent Fuel Storage encompasses dry cask and wet pool systems for managing used nuclear fuel, focusing on thermal management, structural integrity, criticality safety, and long-term degradation under environmental stressors.
Researchers analyze spent fuel storage through modeling of heat transfer, radiation shielding, and material degradation in casks and pools. Key studies validate Monte Carlo codes for criticality safety (Jang et al., 2018, 39 citations) and develop fuel performance codes for dry storage (Rossiter, 2011, 56 citations). Over 20 papers from the provided list address storage cask designs, burnup credit, and economic comparisons.
Why It Matters
Safe spent fuel storage enables nuclear plant decommissioning and interim solutions until permanent repositories exist, as demonstrated by economic analyses favoring direct disposal over reprocessing under most uranium price scenarios (Bunn et al., 2003, 67 citations). Fukushima highlighted vulnerabilities in pool storage during disasters, prompting improved cask shielding designs (Dauer et al., 2011, 106 citations; Ko et al., 2014, 37 citations). These systems manage high-burnup LWR fuel, reducing public hazard risks through validated technologies (Campbell, 1976, 113 citations).
Key Research Challenges
Criticality Safety Validation
Ensuring spent fuel remains subcritical in storage requires accurate modeling of burnup-dependent compositions. Sensitivity evaluations identify key parameters for PWR packages (DeHart, 1996, 51 citations). Monte Carlo codes like MCS need validation against benchmarks for pools and casks (Jang et al., 2018, 39 citations).
Thermal Management in Dry Casks
Dry storage demands precise heat dissipation modeling for fuel cladding integrity over decades. ENIGMA code supports whole-core analysis for these assessments (Rossiter, 2011, 56 citations). Nuclide decay heating trends complicate high-burnup fuel predictions (Gauld and Ryman, 2000, 36 citations).
Shielding Under Normal Conditions
Dual-purpose casks must attenuate gamma and neutron radiation effectively during storage. Analyses confirm dose rates meet regulatory limits (Ko et al., 2014, 37 citations). Material degradation from environmental stressors adds uncertainty to long-term performance.
