The Benefits of Risk-Informed Decision Making for Dry Cask Spent Nuclear Fuel Storage Systems Ongoing Efforts Related to Implementation of Risk Insights

Probabilistic Risk Assessments Related to Spent Fuel

  • Level 3 PRA of Bolted Storage Casks (EPRI 2004)
  • Preclosure Consequence Analysis (BSC 2008)
  • Level 3 PRA (ongoing NRC Office of Nuclear Regulatory Research)

Implementing Risk Insight Initiatives

  • NRCs Pilot Programs

- Risk tool for assisting dry cask storage amendment reviews

- Graded Approach for Safety Evaluation Report development (e.g., use risk information to revise Tech Specs )

  • Other Initiatives

- NEI White Paper

- Topical Report on Shielding Method of Evaluation

Session Panel

1) Brian Wagner (NRC) - development of risk information and implementation activities at NRC
2) Rod McCullum (NEI) - NEI White Paper and perspectives on NRC initiatives
3) Zita Martin (TVA) - risks associated with handling and operations involving spent fuel storage
4) Kim Manzione (Holtec) - risks benefits and flexibility associated with topical reports
