Functional Arrangement (FA)

ITAAC FA System Package Examples Closed Meeting (Non - Proprietary)

February 14, 2019 ND-19-0152 Page 2 of 26 ONE TEAM. ONE VISION. ONE GOAL.

2 Agenda

  • Examples of FA ITAAC and Documentation

.. ~ Southern Nuclear A Georgia Power Building the future of nuclear power in America

3 FA Example #1 -WSS

  • The Design Description in COL Appendix C section 2.3.12 provides a description of what the system does:

The solid radwaste system (WSS) receives, collects, and stores the solid radioactive wastes received prior to their processing and packaging by mobile equipment for shipment off-site.

4 Example #1 -WSS

  • The major system components to accomplish this are included in Table 2.3.12-2 (there is no Tier 1 Figure for WSS):

7 FA Example #2 -PXS

  • The Design Description in COL Appendix C section 2.2.3 provides a description of what service the system is intended to provide:

The passive core cooling system (PXS) provides emergency core cooling during design basis events. The PXS is as shown in Figure 2.2.3-1 and the component locations of the PXS are as shown in Table 2.2.3-5.

Table 2.2.3-4 Inspections, Tests, Analyses, and Acceptance Criteria No.

ITAAC No.

Design Commitment Inspections, Tests, Analyses Acceptance Criteria 158 2.2.03.01

1. The functional arrangement of the PXS is as described in the Design Description of this Section 2.2.3.

Inspection of the as-built system will be performed.

The as-built PXS conforms with the functional arrangement as described in the Design Description of this Section 2.2.3.

13 FA Example #3 -DWS

  • The Design Description in COL Appendix C section 2.3.14 provides a description of what the system does:

The demineralized water transfer and storage system (DWS) receives water from the demineralized water treatment system (DTS), and provides a reservoir of demineralized water to supply the condensate storage tank and for distribution throughout the plant.

ND-19-0152 Page 14 of 26

14 Example #3 -DWS

  • ITAAC 2.3.14.01 (Continued):
  • The Design Description in COL Appendix C section 2.3.14 goes on to provide additional description of what the DWS does:

Demineralized water is processed in the DWS to remove dissolved oxygen. In addition to supplying water for makeup of systems which require pure water, the demineralized water is used to sluice spent radioactive resins from the ion exchange vessels in the chemical and volume control system (CVS), the spent fuel pool cooling system (SFS), and the liquid radwaste system (WLS) to the solid radwaste system (WSS)

ND-19-0152 Page 15 of 26

15 Example #3 -DWS

  • The major system components to accomplish this are included in Table 2.3.14-3 (there is no Tier 1 figure for DWS):
  • Because there is no Tier 1 figure for DWS and limited components listed on Table 2.3.14-3, four additional components were added per procedure ND-RA-001-012 to address the design description.
