SUMMARY

OF THE MARCH 7, 2018, TELECONFERENCE WITH NUSCALE POWER, LLC TO DISCUSS STAFFS QUESTIONS RELATED TO NUSCALES APPROACH TO INITIAL PLANT TEST PROGRAM The following table captures the summary of discussions, specifically, staffs questions and NuScales response.

Item Staffs Comment Status No.

1 Provide an overview of the This item has been identified as out of scope per the new NuScale initial test program review approach regarding the NuScale Power, LLC (ITP) approach to testing and (NuScale), initial test program (ITP). For more details see the graded approach to memoranda, Proposed Pilot Approach for the NuScale preoperational testing (see Power, LLC, Initial Test Program Review, dated March 7, Section 14.2.3.2, Graded 2018 (ADAMS Accession No. ML18060A298). Therefore, Approach to Testing.) this item will not be required for review at the design certification stage. No further actions are needed.

Status: Unresolved/Closed 2 What is the NuScale approach The applicant agreed to remove references of the Remote for the individual test methods? Shutdown station and/or local control panels in the individual For example, which ITP tests test methods.

are required to be tested only from the main control room Status: Resolved / Confirmatory Item (MCR) (e.g., visual observation), remote shutdown station (RSS), and/or local control panels?

3 Last bullet under objectives of The applicant agreed to include a new subsection in FSAR Section 14.2.2, Summary of Section 14.2 to describe the relationship between the Initial Test Program and preoperational tests and ITAAC.

Objectives, states, Status: Resolved / Confirmatory Item complete and document the ITP testing required to satisfy preoperational and startup testing requirements and Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) testing requirements.

Does this imply that the ITP testing satisfies Inspections, Enclosure 1

Tests, Analyses, and Acceptance Criteria (ITAAC) testing requirements? Several ITP testing imply that ITAAC satisfies portions of ITP.

4 What I&C platforms/networks This item has been identified as out of scope per the new are needed to be operational to review approach regarding the NuScale ITP. For more perform the ITP? For example, details see memoranda, Proposed Pilot Approach for the starting with Table 14.2-1: NuScale Power, LLC, Initial Test Program Review, dated Spent Fuel Pool Cooling March 7, 2018 (ADAMS Accession No. ML18060A298).

System Test # 1, discuss the Therefore, this item will not be required for review at the following: design certification stage. No further actions are needed.

• Is the MCR required to be fully operational prior to Status: Unresolved/Closed performing any ITP tests?

• Is making the MCR operational part of an ITP test? If so, which ITP test?

If not, which ITAAC.

5 As it pertains to question # 1 This item has been identified as out of scope per the new (shown above), discuss how review approach regarding the NuScale ITP. For more the interfaces between different details see memoranda, Proposed Pilot Approach for the workstations in the MCR and NuScale Power, LLC, Initial Test Program Review, dated RSS will be tested. March 7, 2018 (ADAMS Accession No. ML18060A298).

Therefore, this item will not be required for review at the design certification stage. No further actions are needed.

Status: Unresolved/Closed 6 On the premise that the factory The applicant agreed to include a new subsection in FSAR acceptance testing (FAT) would Section 14.2 to describe the overlap of testing concepts for satisfy the logic for the I&C the nonsafety-related platforms platforms, does this include FAT for the nonsafety-related Status: Resolved / Confirmatory Item platforms? If not, will there be a FAT for nonsafety-related platforms?

7 FSAR Table 1.9-2, The applicant agreed to include a statement in FSAR Conformance with Regulatory Section 14.2.7 to describe the deviations from Regulatory Guides, includes an Guide 1.68 and the new review approach for the NuScale identification and description of ITP.

deviations from the guidance in the NRC Regulatory Guides, Status: Resolved / Confirmatory Item as well as suitable justifications for any alternative approaches proposed. This table identifies deviations for Regulatory Guide 1.68, Initial Test Programs for Water-Cooled Nuclear Power Plants, Revision 4. Describe the deviations in FSAR Section 14.2, Initial Test Program.

8 Are all plant controllers and This item has been identified as out of scope per the new indications available in the review approach regarding the NuScale ITP. For more Module Control System (see details see memoranda, Proposed Pilot Approach for the Table 14.2-61, Module NuScale Power, LLC, Initial Test Program Review, dated Control System Test # 61)?

Are the indications monitored Therefore, this item will not be required for review at the in the main control room design certification stage. No further actions are needed.

identical to the remote shutdown station (RSS) (e.g., Status: Unresolved/Closed Test 1, component level test vi)? If not, what signals are designed to be displayed in the RSS?
