9 ITP Overview

• Current focus is procedure development

• Staffing in progress

• Project first power block testing in last half of 2018 10

Crediting China for First Plant Only and First Three Plant Only Tests (ITP-1)

• The VEGP 3&4 Combined Licenses (COLs) currently require First Plant Only Tests (FPOTs) be performed on both Unit 3 and Unit 4.

• If Licensee would like to credit a test performed at a previous plant (unit), a LAR is required.

• SNC would like the option to credit testing completed on the China AP1000 units.

• The SNC intent is to submit LARs covering China FPOT/F3POT applicability.

• The LAR scope will be split:

• Pre-operational tests

• Start-up tests Technical Exchange between SNC and NRC was held on 03-08-2018 Planned ITP-1 LAR Submittal for Pre-Operational Test Scope 07-31-2018 11

Revision to Natural Circulation and PRHR Startup FPOT LAR 84 (LAR 17-041)

• This LAR splits Natural Circulation test into two phases: one portion remains in low power testing, the other will be moved into power ascension testing.

• The proposed change in test phase creates more suitable plant conditions to run the test while ensuring safe plant operations.

Submitted 11-17-2017; Requested Approval 11-18-2018 12

PRHR Heat Transfer and IRWST Heat Up Test Acceptance Criteria Change LAR 155 (LAR 17-033)

• The proposed changes revise the methodology and acceptance criteria for the IRWST heatup preoperational test. The 3 specific changes are below:

• Proposed change to allow for the observation of the IRWST thermal profile during both natural circulation and forced flow PRHR heat exchanger tests.

• The current acceptance criterion requires the data from the IRWST heatup test to verify the RCS safe shutdown temperature criterion. The newly proposed acceptance criterion requires the test to demonstrate that the average IRWST heatup is consistent with the PRHR heat exchanger heat transfer.

• Update to reference in COL.

• This change allows for a one-to-one comparison between the as-built plant and the safety analysis Submitted 10-06-2017; Requested Approval 08-21-2018 13

Tier 1/Tier 2* Editorial LAR LAR 148 (LAR 17-042)

• Supplement to this LAR(submittal, RAD) will propose changing the DCD, Rev. 19, references in COL to UFSAR references

• Enable use of existing 50.59 /

departure evaluation process when making changes to Chapter 14 sections referenced in COL

• Discussed during 03/01/18 Public Call 14
