  1. Issues Involving Storage and Transportation of High Burnup Nuclear Fuel Marvin Resnikoff, Ph.D. Before SCE Community Engagement Panel San Juan Capistrano Community Center May 6, 2014

  2. PWR Fuel Assembly

  3. San Onofre NUHOMS

  4. HI-STORM Cask

  5. CT Yankee Dry Storage

  6. Cladding Outer Surface Thickness

  7. Storage Issues • Little technical support for NRC approval of high burnup fuel (HBF). Experiment in the field • Total amount of HBF unknown. NRC survey. • Storage postponed up to 20 years; 32 PWR canister extends cooldown period. • Cladding defects major problem for HBF; HBF may not be retrievable. HBF should be canned. • Long-term storage may not be possible in a salt environment.

  8. HI-STAR Transportation System

  9. Hypothetical Accident Drop Test

  10. Impact Locomotive Sill

  11. Hump RR Crossing Cask

  12. Side Impact

  13. HI-STAR Transportation Overpack Cross-Section

  14. Neutron Shield

  15. Fire Lac Megantic, Quebec

  16. Transportation Issues • Realistic low probability, high consequence accidents should be examined. • Side Impact rail accidents may shatter HBF cladding. • Long duration, high temperature fires may involve oil tankers. Same tracks. NRC has not quantified the statistical likelihood.
