In addition, the three CCNPP Unit 2 Reactor Vessel Supports were performed to satisfy the requirements of the Third Ten-Year Interval. These exams were identified as omitted from previous program plans and added after the 2009 outage. These exams were not credited towards the Fourth Ten-Year Interval.

As an alternate to the requirements of the ASME Boiler and Pressure Vessel Code (B&PVC), Section Xl, Article IWA-6000, CCNPP is implementing ASME Code Case N-532-4, "Alternative Requirements to Repair and Replacement Documentation Requirements and Inservice Summary Report Preparation and Submission as Required by IWA-4000 and IWA-6000,Section XI, Division 1." Regulatory Guide 1.147, Revision 16 (Oct. 2010), approved ASME Code Case N-532-4 for use. This report complies with the requirements of ASME Code Case N-532-4.

In accordance with ASME Section Xl, IWB-2412(a), IWC-2412, IWD-2412, and IWE-2412(a), and with the exception of those examinations that are limited to components selected for examination under Examination Categories B-L-2 and B-M-2 and required only when the pump or valve is disassembled as specified in Table IWB-2500-1, IWC-2500-1, IWD-2500-1, IWF-2S00-1, and IWE-2500-1, including those examinations which CCNPP has requested and received approval in the form of requests for relief or alternates, the required examinations in each examination category have been completed for the First outage of the First Inspection Period of the Fourth Inspection Interval in accordance with Tables IWB-2412-1, IWC-2412-1, IWD-2412-1, and IWE-2412-1.
