Exelon Generation Company R. E. Ginna Nuclear Power Plant Sixth Interval

1.0 General

1.1 The examination, service life monitoring and testing of all safety related snubbers at R.

E. Ginna Nuclear Power Plant (Ginna) will be implemented and performed in accordance with ER-GI-330-1007, "Snubber Inservice Testing Program" to assess the required operational readiness of these snubbers during a seismic or other event, initiating dynamic loads.

1.2 The Snubber program, as defined within ER-GI-330-1007, establishes visual examination, operational readiness testing and service life monitoring requirements, pertaining to all program snubbers that are required for safe shutdown of the reactor, maintaining the safe shutdown condition, mitigating the consequences of an accident, or to ensure the integrity of the reactor coolant pressure boundary.

1.2.1 The examination boundaries are the snubber assembly from pin to pin inclusive. Integral and nonintegral attachments for snubbers will be evaluated within the Ginna ISi program, in accordance with the requirements of the ASME Code Section XI, 2013 Edition.

1.2.2 The snubbers included in this program are identified within the ER-GI-330-1007 Snubber IST Program Document.

1.3 The Snubber Program described in ER-GI-330-1007 adheres to the requirements of ASME OM Code, Section IST, 2012 Edition, as required by 10CFR50.55a(b)(3)(v)(B).

2.0 Examination, Testing and Monitoring Requirements:

2.1 Visual Examinations and Operational Readiness Testing will be performed to the extent specified within ER-GI-330-1007 and in accordance with Exelon fleet administrative procedures ER-AA-330-004 and ER-AA-330-010.

2.2 Snubbers are grouped into Defined Test Plan Groups, (DTPG's) by design type, and in accordance with ISTD-5252 and ISTD-5253 for testing purposes. The DTPG's at Ginna are specified in ER-GI-330-1007.

2.3 The Service Life of all snubbers in this program will be monitored and snubbers replaced or reconditioned as specified in ER-GI-330-1007 and required by Exelon fleet administrative procedure ER-AA-330-011 to ensure that the service life is not exceeded before the next scheduled system or plant outage, or during a period when the snubber is required to be operable. The replacement or reconditioning of snubbers will be documented, and records retained in accordance with Ginna Procedures.

3.0 Examination and Testing Methods:

3.1 Visual Examinations will be performed by individuals qualified in accordance with ISTA-1500(e). Visual Examinations and Operational Readiness Testing shall be performed to verify the requirements specified within ER-Gl-330-1007 in accordance with the requirements of Subsection ISTD.

Page 4 of6 ER-GI-330-1008 Revision 0

Exelon Generation Company R. E. Ginna Nuclear Power Plant Sixth Interval 4.0 Examination and Testing Frequency:

4.1 Inservice Visual Examinations and Pre-and In-service Operational Readiness Testing will be performed at the frequency specified within ER-GI-330-1007.

4.2 Preservice Visual Examinations will be performed whenever new snubber locations are installed, or after system replacements or modifications as specified in ER-GI-330-1007 in accordance with Subsection ISTD-4100.

5.0 ASME OM Code Case, OMN-13 5.1 Code Case OMN-13 Rev. 2, which allows the extension of the visual examination interval, is approved for use by the NRC in Regulatory Guide 1.192 Rev. 2 (March 2017) and will be used during the Sixth Interval upon approval of Ginna Relief Request SR-1, submitted June 26, 2019.

6.0 Examination, Testing and Monitoring Evaluation:

6.1 Snubbers that do not appear to conform to the Visual Examination requirements of ER-GI-330-1007 and procedure ER-AA-330-004, will be evaluated and appropriate corrective action taken.

6.2 Snubbers that do not appear to conform to visual examination acceptance requirements and are later confirmed as operable as a result of operational readiness testing, may be declared operable for the purpose of establishing the next visual examination interval, providing that the unacceptable condition did not affect operational readiness of the snubber.

6.3 Snubbers that do not meet the Operational Readiness Testing acceptance criteria in ER-GI-330-1007 and procedure ER-AA-330-010 will be evaluated to determine the cause of the failure and appropriate corrective action will be taken.

6.4 The service life of every snubber is evaluated at least once each fuel cycle using manufacturing input and engineering information gained through consideration of the snubber service conditions and inservice Operational Readiness test results in accordance with ER-GI-330-1007.

7.0 Repair, Replacement and Modification Requirements:

7.1 Repairs, Replacements and Modifications performed on snubbers under this program shall conform, as applicable, to the requirements specified within the Ginna Repair and Replacement Program.

8.0 Scheduling

8.1 The Visual Examinations and Operational Readiness Testing schedules will be established, tracked and maintained within the Programs Engineering Department.

8.2 The Snubber Testing Program will identify, and track expanded, or additional testing and/or examinations as specified and required by ER-GI-330-1007 in accordance with Subsection ISTD.
