Statistical analysis of the K West fuel element visual examination results

Phase Startup Initiative Phases 3 and 4 Test Plan and Test Specification ( OCRWM)

“…Twenty-nine canistcrs are selected .from the K West Basin population to provide 406 assemblies for cleaning during the validation test per Stegen and Sexton (2000). Welsh and Pitner (1998) describe an analysis of visual cxarninations of approximately 250 assemblies from 20 K West Basin canisters. The analysis indicates that, at the 0.05 level of signilicance.…”

“…This is demonstrated by evaluating cleaning of a 29 canister sample from the basin population ). Welsh and Pitner (1998) describe an analysis of visual examinations of approximately 250 assemblies from 20 K West basin canisters. The analysis indicates that, at the 0.05 level of significance, no relationship exists between outer element dama e and storage parameters (canister type, fuel type, key date, years encapsulated, and 24fPu content).…”
