The examinations summarized in this report were performed in accordance with the 1989 Edition with no Addenda of the ASME Code,Section XI, which is applicable to the South Texas Project, Unit 2, second ten-year interval (10/19/2000-10/18/2010), third period (10/19/2007-10/18/2010). This report covers selected ASME Code Class 1, 2, and 3 systems and components, and component supports. The results are documented in accordance with the requirements of ASME Section XI Code Case N-532-4. Table 1 lists the relevant indications found and their disposition. Table 2 lists those systems and components for which repair or replacement was done.
Examinations and tests required by the Code are scheduled in accordance with "Inspection Program B" as defined in IWB-2412 for ASME Code Class 1 systems and components. IWC-2412 is applied to ASME Code Class 2 systems and components, IWD-2412 to ASME Code Class 3 systems and components, and IWF-2412 to component supports.
ASME Code Class 1 components are examined as prescribed by Table IWB-2500-1 and the applicable Examination Categories, which established the examination frequency at each refueling outage. ASME Code Class 2 systems and components are examined in accordance with Table IWC-2500-1, Examination Categories. ASME Code Class 3 systems and
