INSERVICE EXAMINATIONS Page 4 of 9 ABSTRACT ASME Section Xl Code Case N-532-4 requires submission of the Owner's Activity Report to the regulatory and enforcement authorities having jurisdiction at the plant site within 90 calendar days of the completion of each refueling outage.

This Owner's Activity Report summarizes the results of the Nine Mile Point Nuclear Station (NMPNS), Unit 2, American Society of Mechanical Engineers (ASME)Section XI In-service Inspection, Risk-Informed Inspection, Containment In-service Examinations, and Pressure Tests performed since the last report dated June 15, 2012 through Refueling Outage Fourteen (RFO14) ending April 29, 2014. RFO14 is the second of two outages scheduled during the Second In-service Inspection Period that started on April 5, 2011 and is scheduled to end on April 4, 2015.

The attached Table 1 and 2 include flaws and conditions (those meeting the requirements of Code Case N-532-

4) identified since the last Owner's Activity Report following Refueling Outage RFO-1 3.

As an alternate to the requirements of the ASME, Boiler and Pressure Vessel Code (B&PVC),Section XI, Article IWA-6000, NMPNS is implementing ASME Code Case N-532-4, Alternative Requirements to Repair and Replacement Documentation Requirements and In-service Summary Report Preparation and Submission as Required by IWA-4000 and IWA-6000,Section XI, Division 1". Regulatory Guide 1.147, Revision 15, approved ASME Code Case N-532-4 for use. This Report complies with the requirements of Code Case N-532-4 and the conditions identified in RG 1.147.

OWNER'S ACTIVITY REPORTS - FORM OAR-1 Owner Activity Report Form OAR-1 was prepared and certified upon completion of the Nine Mile Point Unit 2, 2014 refueling outage (RFO14) examination activity in accordance with the following NMPNS inspection plans and schedules:

CNG-NMP2-ISI-003, Third Ten-Year In-service Inspection Plan and Implementing Schedule, (includes the Alternate Risk-Informed Inspection Program)

CNG-NMP2-CISI-002, Second Containment In-service Inspection Plan and Implementing Schedule.

NMP2-PT-008, Inservice Pressure Testing Program Plan In addition to the Owner's Activity Report, Form OAR-i, the following Tables are also included:

a. Items with Flaws or Relevant Conditions that Require Evaluation for Continued Service, Table 1, 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, identifies those items containing flaws or relevant conditions that exceeded Division 1 acceptance criteria. This information is required even if the discovery of the flaw or relevant condition that necessitated the repair/replacement activity did not result from an examination or test required by Division 1. If the acceptance criterion for a particular item is not specified in Division 1, the provisions of IWA-3100(b) shall be used to determine which repair/replacement activities are required to be included in the abstract.

In accordance with ASME Section XI, IWB-2412(a), IWC-2412, IWD-2412 IWE-2412(a), and IWF-2410(b) and with the exception of the examinations that may be deferred until the end of the inspection interval as specified in Table IWB-2500-1, IWC-2500-1, IWD-2500-1, IWF-2500-1 and IWE-2500-1, including those examinations which NMPNS has requested and received approval in the form of proposed alternatives in accordance with 10CFR50.55a(a)(3), the required examinations in each examination category have been completed for the First In-service Inspection Period in accordance with Tables IWB-2412-1, IWC-2412-1, IWD-2412-1, IWE-2412-1, and IWF-2410-2.

Station procedures require Design Engineering Evaluation for any leakage originating from a bolted connection.

Condition Report CR-2014-003845 documents an undesirable condition associated with 80 drops per minute leakage from the ASME Class 1 valve 2RCS*HYV1 7B body-to-bonnet bolted flange connection. A Design Engineering Evaluation concludes that the identified leakage is acceptable as-is for continued service. Work Order C92657492 has been generated to address this condition.

Condition Report CR-2014-003847 documents an undesirable condition associated with 20 drops per minute leakage from the ASME Class 1 valve 2RCS*MOV1 0B body-to-bonnet bolted flange connection. A Design Engineering Evaluation concludes that the identified leakage is acceptable as-is for continued service. Work Order C92654714 has been generated to address this condition.

Condition Report CR-2014-003849 documents an undesirable condition associated with leakage from Control Rod Drive bolted flange connections. The as-found leakage ranged from 2 drops per minute to 80 drops per minute.

The as-left leakage was reduced significantly following scramming of control rod drives.

A Design Engineering Evaluation concludes that the identified leakage is acceptable as-is for continued service.
