SUMMARY

OF A PUBLIC MEETING WITH SOUTHERN NUCLEAR OPERATING COMPANY ON OCTOBER 10, 2019 The U.S. Nuclear Regulatory Commission (NRC) staff held a Category 1 public meeting with Southern Nuclear Operating Company (SNC) on October 10, 2019. The purpose of the meeting was to discuss License Amendment Request (LAR)19-017, Removal of the Preoperational Passive Residual Heat Removal Heat Exchanger Natural Circulation Test and a proposed LAR and exemption associated with modification of the primary coolant system (PCS) wetted perimeter test.

The meeting notice can be found in the Agencywide Documents Access and Management System (ADAMS) Accession No. ML19248C473. The meeting notice was posted on the NRC public website. Enclosures 1 and 2 are the meeting agenda and attendance list for the meeting, respectively. The documents referenced during the discussion can be found at the ADAMS Accession Nos. given below:

• LAR 19-017: Removal of the Preoperational ML19249C738 Passive Residual Heat Removal Heat Exchanger Natural Circulation

V. Hall Summary of Meeting:

Technical Discussion on Removal of the Preoperational Passive Residual Heat Removal Heat Exchanger Natural Circulation (LAR 19-017)

On October 10, 2019, staff from the NRC conducted a public meeting with representatives from SNC to discuss LAR 19-017. The LAR requests a change to remove the natural circulation test of the passive residual heat removal (PRHR) heat exchanger, which is conducted during preoperational testing, from the scope of the initial test program. At a previous public meeting on September 26, 2019 (meeting summary can be found at ADAMS Accession No.

ML19270G587), the NRC explained the reasons that it did not find adequate justification for the proposed removal of an initial test and related modification to Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) requiring SNC to conduct a PRHR heat exchanger natural circulation test. During this meeting, the NRC reiterated its concern that the forced flow test would not be equivalent to the natural circulation test. SNC explained the methods they will use to validate flowrates, specifically highlighting driving head and line resistance calculations. SNC also discussed other options they have considered such as shortening the natural circulation test or performing the test at a lower temperature. The public meeting concluded with the NRC reiterating that it does not have sufficient information to complete its acceptance review. The NRC offered two potential paths forward for SNC to consider:

1. SNC submit supplemental information to describe how the forced flow scheme will meet the acceptance criteria for the natural circulation test.

2. SNC evaluate if the natural circulation test could be conducted at lower temperature or at a shorter duration.

Portions of the meeting were closed to the public due to proprietary discussion technical details.

At the conclusion of each presentation, there was an opportunity for the public to provide comments and to ask questions to the NRC staff. The NRC provided the public additional information regarding the kind of topics that were going to be discussed during the proprietary portion of the meeting and also if the tests were done with different heat removal capacities.

Pre-submittal Meeting on Proposed LAR and Exemption Associated with Modification of the PCS Wetted Perimeter Test On October 10, 2019, staff from the NRC conducted a public meeting with representatives from SNC to conduct a pre-submittal meeting for a proposed LAR and exemption associated with modification of the PCS wetted perimeter test. SNC discussed the reason for the proposed

V. Hall change and the proposed licensing bases changes. The NRC asked clarifying questions to understand the bases of the statements made in the LAR. SNC took an action to evaluate the following changes to the draft LAR:

1. Add language to describe how the test is performed to confirm the wetted perimeter coverage.

2. Clarify the percentage of coverage will be dependent on the different elevation and circumferences.
