GO2-21-101 Enclosure Page 1 of 2 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION NRC REQUEST NLRP-RAI-1:

Issue The proposed license condition 2.C.(35) as provided in the LAR reads:

The licensee's FSAR supplement submitted pursuant to 10 CFR 54.21(d) and Appendix A of NUREG-2123, as revised pursuant to the criteria set forth in 10 CFR 50.59, during the license renewal application review process, and as supplemented by Commitment Nos. 1, 5, 13, 14, 17, 18, 23, 24, 26, 27, 28, 32, 36, 38, 40, 41, 42, 43, 48, 49, 50, 53, 55, 58, 59, 60, 61, 63, 64, 65, 66, 67, 68, 69, and 70 of Appendix A of NUREG-2123, describes certain future programs and activities to be completed before the period of extended operation. Energy Northwest shall complete these activities no later than JuneJuly 20, 2023, and shall notify the NRC in writing when implementation of these activities is complete.

With the proposed removal of condition 2.C.(34), it will no longer be clear that the FSAR supplement and table of commitments from Appendix A of NUREG-2123 (the SER) are now included in the FSAR itself, which may be revised pursuant to 10 CFR 50.59. The proposed wording in the license amendment request for revised license condition 2.C.(35) indicates that the FSAR supplement itself (as a standalone document) and the table of commitments in Appendix A of NUREG-2123 (the SER) may be revised pursuant to the criteria in 10 CFR 50.59. The regulations at 10 CFR 50.59 specifically govern changes to the facilitys FSAR, not to an FSAR supplement (except as it is incorporated into the FSAR) and not to a table in an SER. Revising these documents pursuant to the criteria in 10 CFR 50.59 does not place these documents within the regulatory framework. The proposed license condition makes no mention of the FSAR, which is the document to be managed by the 10 CFR 50.59 process.

Additionally, the proposed license condition would place all of the commitments as listed in NUREG-2123 into the FSAR, including commitment numbers 55, 56, 57, and 71, when it is the intent of the LAR to exclude these commitments. It is not clear to the staff whether the March 4, 2020 FSAR update added the entire table of commitments, including these four, to the FSAR and the licensee subsequently removed them following a 10 CFR 50.59 review, or whether the license condition should be revised to explicitly exclude these four commitments.

Requested Information (1) Please clarify whether the intent was for license condition 2.C.(35) to convey that the FSAR supplement and Appendix A of NUREG-2123, as standalone documents, would be revised according to 10 CFR 50.59 or whether the revisions would be made to

GO2-21-101 Enclosure Page 2 of 2 the FSAR, which has been updated with the FSAR supplement and table of commitments from NUREG-2123. Please revise the license condition accordingly if necessary.

(2) If the intent is to include all commitments from Appendix A of NUREG-2123 except for commitment numbers 55, 56, 57, and 71, please revise the wording of the proposed license condition to reflect this. Alternately, if these four commitments were originally included in the table and then removed after a 10 CFR 50.59 review (as allowed by the current wording of the license condition), confirm this was the case.

ENERGY NORTHWEST RESPONSE TO NLRP-RAI-1:

The intent of the change to license condition 2.C.(35) was to convey that the commitments identified in NUREG-2123 Appendix A Table A-1 have been incorporated into the Columbia Final Safety Analysis Report (FSAR). Energy Northwest was not clear in stating as part of the incorporation that the 50.59 change process was applied to certain commitments that were completed "one-time" activities or required by a specific license condition. These commitments were removed from the incorporated FSAR Appendix A, Table A-1.

Energy Northwest's intent was to include all commitments from Appendix A of NUREG-2123 except for commitment numbers 55, 56, 57, and 71. Therefore, Energy Northwest proposes the revised the wording for license condition 2.C.(35) as follows:

(35) The licensee's FSAR, as updated with the license renewal FSAR supplement submitted pursuant to 10 CFR 54.21(d) and supplemented with Appendix A of NUREG-2123 with the exception of Commitments Nos. 55, 56, 57, and 71, and as revised pursuant to the criteria set forth in 10 CFR 50.59, during the license renewal application review process, and as supplemented by Commitment Nos. 1, 5, 13, 14, 17, 18, 23, 24, 26, 27, 28, 32, 36, 38, 40, 41, 42, 43, 48, 49, 50, 53, 55, 58, 59, 60, 61, 63, 64, 65, 66, 67, 68, 69, and 70 of Appendix A of NUREG-2123, describes certain future programs and activities to be completed before the period of extended operation. Energy Northwest shall complete these activities no later than JuneJuly 20, 2023 and shall notify the NRC in writing when implementation of these activities is complete.

Energy Northwest has provided revised markup and retyped pages as attachments to this enclosure.

GO2-21-101 Attachment 1 Page 1 of 1 (34) The information in the FSAR supplement, submitted pursuant to 10 CFR 54.21(d), as supplemented by Commitment Nos. 1, 5, 13, 14, 17, 18, 23, 24, 26, 27, 28, 32, 36, 38, 40, 41, 42, 43, 48, 49, 50, 53, 55, 58, 59, 60, 61, 63, 64, 65, 66, 67, 68, 69, and 70 of Appendix A of NUREG-2123, "Safety Evaluation Report Related to the License Renewal of Columbia Generating DELETED Station" dated May 2012, is henceforth part of the FSAR which will be updated in accordance with 10 CFR 50.71(e). As such, the licensee may make changes to the programs and activities described in the UFSAR supplement and Commitment Nos. 1, 5, 13, 14, 17, 18, 23, 24, 26, 27, 28, 32, 36, 38, 40, 41, 42, 43, 48, 49, 50, 53, 55, 58, 59, 60, 61, 63, 64, 65, 66, 67, 68, 69, and 70 of Appendix A of NUREG-2123 provided the licensee evaluates such changes pursuant to the criteria set forth in 10 CFR 50.59 and otherwise complies with the requirements in that section.

(34) The licensee's FSAR, as updated with the license renewal FSAR supplement submitted pursuant to 10 CFR 54.21(d) and supplemented with Appendix A of NUREG-2123 with the exception of Commitments Nos. 55, 56, 57, and 71, and as revised pursuant to the criteria set forth in 10 CFR 50.59, during the license renewal application review process, and as supplemented by Commitment Nos. 1, 5, 13, 14, 17, 18, 23, 24, 26, 27, 28, 32, 36, 38, 40, 41, 42, 43, 48, 49, 50, 53, 55, 58, 59, 60, 61, 63, 64, 65, 66, 67, 68, 69, and 70 of Appendix A of NUREG-2123, describes certain future programs and activities to be completed before the period of extended operation. Energy Northwest shall complete these activities no later than JuneJuly 20, 2023 and shall notify the NRC in writing when implementation of these activities is complete.

(35) To prevent lateral motion of the core plate, the licensee shall install core plate wedges around the periphery of the core plate within the shroud on or before December 20, 2021. Upon completion of the core plate wedge installation, the licensee shall submit a written report to the NRC staff summarizing the results of the installation. The licensee shall also submit a written report regarding any corrective action taken related to core plate rim hold-down bolts or core plate wedges and the results of extent of condition reviews on or before December 20, 2021.
