U.S. NUCLEAR REGULATORY COMMISSION CATEGORY 1 PUBLIC TELECONFERENCE TO DISCUSS NUSCALE POWER, LLCS DESIGN CERTIFICATION APPLICATION REQUEST FOR ADDITIONAL INFORMATION RESPONSE 9122, RELATED TO NUSCALE STANDARD DESIGN CERTIFICATION 048 - 10.04.07 - CONDENSATE AND FEEDWATER SYSTEM APPLICATION SECTION: 10.4.7 January 31, 2018 General Comments

1. Question 10.4.7-1 requested condensate and feedwater system piping and instrumentation diagram (P&ID) be provided and included in the NuScale final safety analysis report (FSAR). In its response the applicant did not include the requested P&ID instead revised power cycle block diagram FSAR Figure 10.1-1.

a. NuScale Power, LLC (NuScale) would provide a simplified system diagram of the condensate feed water system that will be available at the NuScale Rockville, Maryland, office for audit.

2. Question 10.4.7-1 requested information on condensate and feedwater system (CFWS) inspection and testing after the nuclear plant module (NPM) is reinstalled in its bay and connected back to the CFWS system after refueling is completed. In its response to the question the applicant states that the CFWS is outside the scope of general design criteria (GDC) 45 and 46, and propose removing what they consider erroneous language from the FSAR. The U.S. Nuclear Regulatory Commission staff disagrees with the applicant conclusion that GDC 45 and 46 is not applicable.

a. NuScales assertion that GDC 45 and 46 are not applicable, because the CFWS contains SSCs that are part of the DHRS boundary. There would be no change to their RAI response.

3. Question 10.4.7-3 requested the applicant propose a combined operating license (COL) item to provide operating and maintenance procedures to address water hammer issues for the CFWS. The applicant response did not include the addition of the requested COL item. The COL items should have applicant provide procedures in accordance with NUREG-0927 as was done in APR 1400 DCD COL Item 10.4(8), and USAPWR DCD COL item 10.4(6).

a. NuScale stated that FSAR Tier 2, Section 3.6.3.1.4 indicates that The feedwater system (FWS) and steam generator (SG) contain design features that minimize the potential for and effect of water hammer. There would be no change to their RAI response.
