slide-22
SLIDE 22

Observations

  • In situ inspections of 8 canisters

– Canisters identified for inspection included 8/3 and 7/22 canisters – Most observed wear was very shallow at 0.000 to 0.005 inches – Deepest wear was .026 inches (< thickness of credit card) – ASME code conservatively .0625 inches

UNDERSTANDING SCRATCHES

slide-23
SLIDE 23

23

Conclusions

  • Wear marks far below depth that would be a safety

concern

  • Incidental wear during downloading poses no safety

significance

  • Passive oxide layer re-forms to protect from corrosion
  • Canister containment integrity remains robust
  • Inspection & Maintenance program will monitor over time

Canister Storage System

  • SONGS Canisters are steel canisters stored in a

concrete monolith/module

  • SONGS Canisters will be placed in a

TRANSPORTATION overpack when an offsite facility is available

  • 92% of all the dry storage systems loaded in the

U.S., use canisters, approximately 225 (less than 8%) are thick-wall casks

  • All 15 shutdown sites use canister-based

technology

  • Of the recent shutdown sites, over 546 canisters

have been loaded or are planned (e.g., SONGS, Fort Calhoun)
