NuScale Final Safety Analysis Report Fuel Handling Equipment NuScale US460 SDAA 9.1-42 Draft Revision 2 Table 9.1.4-2: Classification of Structures, Systems, and Components SSC (Note 1)

Location SSC Classification (A1, A2, B1, B2)

Augmented Design Requirements (Note 2)

Quality Group/Safety Classification (Ref RG 1.26 or RG 1.143)

(Note 3)

Seismic Classification (Ref.

RG 1.29 or RG 1.143)

(Note 4)

FHE, Fuel Handling Equipment

  • Fuel handling machine
  • New fuel elevator RXB B2
  • ANSI-ANS-57.1-1992

N/A I

New fuel jib crane RXB B2

N/A II Note 1: Acronyms used in this table are listed in Table 1.1-1 Note 2: Additional augmented design requirements, such as the application of a Quality Group, Radwaste safety, or seismic classification, to nonsafety-related SSC are reflected in the columns Quality Group / Safety Classification and Seismic Classification, where applicable. Environmental Qualifications of SSC are identified in Table 3.11-1.

Note 3: Section 3.2.2.1 through Section 3.2.2.4 provides the applicable codes and standards for each RG 1.26 Quality Group designation (A, B, C, and D). A Quality Group classification per RG 1.26 is not applicable to supports or instrumentation that do not serve a pressure boundary function. Section 3.2.1.4 provides a description of RG 1.143 classification for RW-IIa, RW-IIb, and RW-IIc.

Note 4: Where SSC (or portions thereof) as determined in the as-built plant that are identified as Seismic Category III in this table could, as the result of a seismic event, adversely affect Seismic Category I SSC or result in incapacitating injury to occupants of the control room, they are categorized as Seismic Category II consistent with Section 3.2.1.2 and analyzed as described in Section 3.7.3.8.
