This Owner's Activity Report (OAR) summarizes the results of the Calvert Cliffs Nuclear Power Plant (CCNPP),

Unit 1, American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (B&PVC), Section Xl, Inservice Inspection (ISI) examinations performed in Refueling Outage twenty one (RFO-21) during the period from April 9, 2012 through March 20, 2014 of the Second Inservice Inspection Period which began on October 10, 2012 and is scheduled to end on October 9, 2016, and the Third outage of the Fourth Ten-Year Inservice Inspection Interval which began on October 10, 2009 and is scheduled to end on June 30, 2019.

This report complies with the requirements set forth by ASME B&PVC,Section XI 2004 Edition, Article IWA-6000 as modified by ASME Code Case N-532-4, "Repair/Replacement Activity Documentation Requirements and Inservice Summary Report Preparation and Submission."

In accordance with ASME Section Xl, IWB-2400, IWC-2400, IWD-2400, IWE-2400, and IWF-2400, 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, and IWD-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 Second Inspection Period of the Fourth Inspection Interval in accordance with Tables IWB-241 2-1, IWC-241 2-1, IWD-241 2-1, IWE-241 2-1 and IWF-241 0-2.

Owner's Activity Reports - Form OAR-i Owner's Activity Reports, Form OAR-i, were prepared and certified upon completion of the Calvert Cliffs Nuclear Power Plant Unit 1, 2014 Refueling Outage (RFO-21) examination activity in accordance with the following inspection plans:

Fourth Inservice Inspection Program Plan Second Interval Containment Inservice Inspection Program Plan Fourth Interval Inservice Inspection Pressure Testing Program Plan In addition to the Owner's Activity Reports, Form OAR-i, the following Tables are also included:

a.

Items with Flaws or Relevant Conditions that Require Evaluation for Continued Service, Table 1, which provides a listing of item(s) with flaws or relevant conditions that required evaluation to determine acceptability for continued service, whether or not the flaw or relevant condition was discovered during a scheduled examination or test, and provides such information as Examination Category, Examination Item Number, Item Description, Flaw Characterization (as required by IWA-3300).

b.

Abstract of Repairs, Replacements or Corrective Measures Required for Continued Service, Table 2, which identifies those items containing flaws or relevant conditions that exceeded the ASME XI acceptance criteria (IWB-3000, IWC-3000, and IWD-3000) or in the case of supports, IWF-3000 acceptance criteria; even though the discovery of the flaw or relevant condition that necessitated the repair, replacement, or corrective measure, may not have resulted from an examination or test required by ASME Section Xl, and provides such information as Code Class, item description, description of work, date completed, and the repair replacement plan number.

This Owner's Activity Report (OAR) summarizes the results of the Calvert Cliffs Nuclear Power Plant (CCNPP),

Unit 1, American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (B&PVC), Section Xl, Inservice Inspection (ISI) examinations performed in Refueling Outage twenty one (RFO-21) during the period from April 9, 2012 through March 20, 2014 of the Second Inservice Inspection Period which began on October 10, 2012 and is scheduled to end on October 9, 2016, and the Third outage of the Fourth Ten-Year Inservice Inspection Interval which began on October 10, 2009 and is scheduled to end on June 30, 2019.

This report complies with the requirements set forth by ASME B&PVC,Section XI 2004 Edition, Article IWA-6000 as modified by ASME Code Case N-532-4, "Repair/Replacement Activity Documentation Requirements and Inservice Summary Report Preparation and Submission."

In accordance with ASME Section Xl, IWB-2400, IWC-2400, IWD-2400, IWE-2400, and IWF-2400, 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, and IWD-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 Second Inspection Period of the Fourth Inspection Interval in accordance with Tables IWB-241 2-1, IWC-241 2-1, IWD-241 2-1, IWE-241 2-1 and IWF-241 0-2.

Owner's Activity Reports - Form OAR-i Owner's Activity Reports, Form OAR-i, were prepared and certified upon completion of the Calvert Cliffs Nuclear Power Plant Unit 1, 2014 Refueling Outage (RFO-21) examination activity in accordance with the following inspection plans:

Fourth Inservice Inspection Program Plan Second Interval Containment Inservice Inspection Program Plan Fourth Interval Inservice Inspection Pressure Testing Program Plan In addition to the Owner's Activity Reports, Form OAR-i, the following Tables are also included:

a.

Items with Flaws or Relevant Conditions that Require Evaluation for Continued Service, Table 1, which provides a listing of item(s) with flaws or relevant conditions that required evaluation to determine acceptability for continued service, whether or not the flaw or relevant condition was discovered during a scheduled examination or test, and provides such information as Examination Category, Examination Item Number, Item Description, Flaw Characterization (as required by IWA-3300).

b.

Abstract of Repairs, Replacements or Corrective Measures Required for Continued Service, Table 2, which identifies those items containing flaws or relevant conditions that exceeded the ASME XI acceptance criteria (IWB-3000, IWC-3000, and IWD-3000) or in the case of supports, IWF-3000 acceptance criteria; even though the discovery of the flaw or relevant condition that necessitated the repair, replacement, or corrective measure, may not have resulted from an examination or test required by ASME Section Xl, and provides such information as Code Class, item description, description of work, date completed, and the repair replacement plan number.
