This preliminary SE chapter includes numerous items characterized for the purpose of this SE chapter as Open Items (OIs). However, many of these issues are unresolved without a clearly defined path toward resolution identified at this time and may involve potential legal issues.

Accordingly, this preliminary SE chapter, while useful for illuminating the issues unique to the review of transient and accident analysis for the NuScale design, may not reflect the NuScale revised approach and associated NRC review of that revised approach. The staff provided a version of this preliminary SE chapter to support a meeting with the ACRS held on June 19-20, 2019, to discuss key issues related to this chapter and its associated topical reports.

SUBJECT:
NUSCALE POWER, LLC, DESIGN CERTIFICATION APPLICATION - PRELIMINIARY SAFETY EVALUATION WITH OPEN ITEMS FOR CHAPTER 15, TRANSIENT AND ACCIDENT ANALYSES On January 6, 20171, NuScale Power, LLC (NuScale) submitted its Design Certification Application (DCA) to the U.S. Nuclear Regulatory Commission (NRC) for review, approval, and granting of standard design certification for the NuScale Standard Plant Design. NuScales letter is available in the Agencywide Documents Access and Management System (ADAMS) under Accession No. ML17013A229.
The NRC staffs preliminary safety evaluation (SE) with open items (OIs) for Chapter 15, Transient and Accident Analyses, is based on Chapter 15 of the NuScale DCA, Revision 2.
This preliminary SE chapter includes numerous items characterized for the purpose of this SE chapter as Open Items (OIs). However, many of these issues are unresolved without a clearly defined path toward resolution identified at this time and may involve potential legal issues. For this reason, the staff anticipates that NuScale will make revisions throughout this chapter of the application. Accordingly, this preliminary SE chapter, while useful for illuminating the issues unique to the review of transient and accident analysis for the NuScale design, may not reflect the NuScale revised approach and associated NRC review of that revised approach. The staff provided a version of this preliminary SE chapter to support a meeting with the ACRS held on June 19-20, 2019, to discuss key issues related to this chapter and its associated topical reports. It should be noted that this preliminary SE reflects the staff evaluation as of June 18, 2019.
