Fatigue life of LOFT Class I pipe welds

Technical Report ·
OSTI ID:6803260
This report provides updated calculated LOCE lifetimes of welds in designated LOFT Class 1 piping systems. For each weld, lifetime is defined as the greatest number of cycles of the governing transient such that cumulative usage factor does not exceed 1.0. Results are presented in tabular form. For parts of the pressurizer relief system, the number of relief cycles rather than LOCE cycles govern and are so shown.
