 As equipment ages, and inservice inspections are performed, indications of structural damage or cracking are often observed. Sometimes these are truly life-limiting and warrant immediate repair or corrective action. However, such indications are often artifacts remaining from initial component fabrication, or are due to service degradation mechanisms that do not significantly alter design basis safety margins or remaining life.
SI pioneered the use of fracture mechanics for such evaluations in the nuclear inservice inspection code (ASME Section XI), and has used these techniques to perform numerous evaluations of equipment in nuclear, fossil, hydroelectric and petrochemical facilities. Evaluations have included pressure vessels and piping, pumps and valves, turbo-machinery, and all forms of boiler components (tubing, headers, etc.). SI is an unbiased resource for such evaluations, or for expert third party review of evaluations performed by others.
