SUMMARY

OF THE FEBRUARY 14, 2018, PUBLIC MEETING WITH NUSCALE POWER, LLC, TO DISCUSS THE U.S.

NUCLEAR REGULATORY COMMISSION STAFF QUESTIONS RELATED TO THE INITIAL TEST PROGRAM AND TECHNICAL SPECIFICATIONS FOR INSTRUMENTATION AND CONTROLS On February 14, 2018, representatives of the U.S. Nuclear Regulatory Commission (NRC) and NuScale Power, LLC (NuScale) held a public teleconference meeting to discuss the NRC staffs questions related to the Initial Test Program and technical specification surveillance requirements for the Module Protection System, which are described in Chapter 7, Instrumentation and Controls, Section 14.2, Initial Test Program, and Section 16.3.3, Technical Specifications - Instrumentation, of Part 2 of the NuScale Design Certification Application (DCA); the technical specifications and associated bases are provided in Part 4 of the DCA. A complete copy of NuScales DCA is available on the NRC public Webpage at https://www.nrc.gov/reactors/new-reactors/design-cert/nuscale/documents.html. captures the summary of the topics discussed during the teleconference. The agenda and list of meeting attendees are included in Enclosures 2 and 3, respectively. The meeting notice for this meeting is available in Agencywide Documents Access and Management System under Accession No. ML18039A100.

SUMMARY

OF THE FEBRUARY 14, 2018, TELECONFERENCE WITH NUSCALE POWER, LLC NRC Staffs Questions Related to NuScale Power, LLC Initial Test Program The U.S. Nuclear Regulatory Commission (NRC) staff asked the following questions related to NuScales Initial Test Program (ITP).

1. Provide an overview of the NuScale ITP approach to testing and the graded approach to preoperational testing (see Section 14.2.3.2, Graded Approach to Testing).

2. What is the NuScale approach for the individual test methods? For example, which ITP tests are required to be performed only from the main control room (e.g., visual observation), remote shutdown station, and/or local control panels?

3. Last bullet under objectives of Section 14.2.2, Summary of Initial Test Program and Objectives, states:

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

4. Does Table 14.2-109, List of Test Abstracts, list all of systems in the NuScale design or just systems for the ITP?

Based on time constraints of the meeting, NuScale was not able to give full responses to all of the NRCs questions. Therefore, the NuScale and NRC staff agreed to hold a face-to-face public meeting to discuss NuScales approach to ITP in more detail.

Technical Specification Surveillance Requirements for the Module Protection System The NRC staff asked NuScale the following questions. NuScale advised the staff that detailed discussion and response to the staffs questions would require discussion of NuScale proprietary information. The NRC and NuScale staff agreed to hold a closed meeting on February 21, 2018 to discuss the NRC staffs questions.

NRC Staff Questions:

1. What combination of Fatal, Vital, or Non-Vital faults would render a given module protection system (MPS) channel (or more) inoperable?

2. What action(s) would NuScale take, from a Chapter 16 perspective, if an MPS channel is inoperable?
