FA Example #3 -DWS
• ITAAC 2.3.14.01:
• 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.”

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)”

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.
