~ExelonGeneration. FOURTH INSERVICE INSPECTION Rev. 00 INTERVAL Date: December 17, 2020 2020 OWNER'S ACTIVITY REPORT FOR Page 4 of 8 INSERVICE EXAMINATIONS ABSTRACT ASME Section XI Code Case N-532-5 requires submission of the Owner's Activity Report to the regulatory and enforcement authorrties having jurisdiction at the plant srte within 90 calendar days of the completion of each refueling outage. An alternative to this requirement was authorized by the NRC, as documented in a letter dated April 30, 2020 (Reference ADAMS Accession No. ML20113F041 ), and submittal of this report is compliant with the authonzed alternative.

This Owner's Activity Report summanzes the results of the Nine Mile Point N'uclear Station (NMPNS), Unit 2, American Society of Mechanical Engineers (ASME) Section XJ In-service Inspection, Risk-lnfonned Inspection, Containment In-service Examinations, and Pressure Tests performed since the last report dated June 28, 2018 through Refueling Outage Sixteen (RFO17) ending Apnl 3rd 2020. RFO17 Is the only refueling outage scheduled during the First In-service Inspection Period that started on October 6, 2018 and is scheduled to end on August 22, 2021.

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

These items have been entered into the site corrective action program, as noted herein.

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-532-5, 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 XJ, Division 1. ASME Code Cpse N-532-5 is currently approved for use in Regulatory Guide 1.147, Revision 19, Table 1.

OWNER'S ACTMTY REPORT - FORM OAR-1 The Owner's Activity Report Form OAR-1 was prepared and certified upon completion of the Nine Mile Point Unrt 2, 2020 refueling outage (RFO17) examination activity in accordance with the following NMPNS inspection plans and schedules:

  • NMP8743R02U2-04, ISi Program Plan, Fourth Ten-Year Inspection Interval (includes the Alternate Risk-Informed Inspection Program, Containment lnserv1ce Inspection Program, and lnservice Pressure Testing Program)
  • ER-NM-330-2003, ISi Selection Document, Fourth Ten-Year Inspection Interval (includes schedules for items selected for examination)

In addition to the Owner's Activity Report, Form OAR-1, 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 ltem(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 critena This information Is required even 1f 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 cnterion for a particular rtem 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.
