36 18-044 2019-01 Figure 10.4-17 ECR 72207 NC/CR-11-03747 Accept-As-Is/ Current Penstocks Operation Acceptable This change revised FSAR Figure 10.4-17 to permanently accept the current condition/operation of the Liquid Waste System at the Penstocks, with section of piping removed & valve XVG06904A-LW out of service.

37 18-045 2019-01 Figure 9.2-2, SH1 Figure 9.2-2, SH3 ECR 50933 - Repair Service Water (SW) Pipe Leaks Using PM Caps This change revised FSAR Figure 9.2-2 to move the design flags from the outlet of the XVB03121A(B)-SW to the outlet of the orifice XPS0245A(B). These changes were a result of cavitation damage at the outlet of XVB03121A(B)SW, EDG Cooler A and B Service Water Return Valves, the material downstream is changed to stainless and an orifice is installed to lessen the throttling duty of the valves.

38 18-046 2019-05 Figure 10.4-7A ECR 71630 - Correction to FSAR Section 10 Figure 10.4-7A, Drawing D-302-165, Revision 30 This change revised FSAR Figure 10.4-7A to include Pressure indicator (IPI16631) and the associated HR valve (IPI16631-HR-WI). These changes were made to reflect the as-built configuration of the plant.

39 18-047 2019-03 Figure 5.2-8A ECR 50931, Incore Detector System Ten Path Vent Removal This change revised FSAR Section 5.2, Figure 5.2-8A to incorporate the incore detector system ten path vent removal. This revision consisted of removing portion of the CO2 Purge System tubing and installing an overflow drain line to ILS50402.

40 18-048 2019-01 Figure 9.2-7 ECR 72474 - Piping and Valve Corrections to FSAR Figure 9.27 This change revised FSAR Section 9., Figure 9.27 to reconnect ITI07003B to the Charging/SI Pump cooling water return line and redraw valve symbols for XVT09530A/B/CCC and XVT09686A/B/CCC.

41 18-050 2019-05 Figures 9.5-1 SH 1, 3, 4 & 5 ECR 50628 - Fire Protection Program Transition to NFPA 805 This change revised FSAR Section 9.5.1 Figure 9.5-1, S1, S3, S4, and S5 to correct errors identified during ECR 50628 implementation. Figure 9.5-1 S1 was revised to add a reducer downstream of XVT06017-FS and to Shift border for AFSPH back to proper location. Figure 9.5-1 S3 & S4 was revised to remove safety classification flags to show fire hose stations that are listed in SAP-131A and Figure 9.5-1 S3 & S4. Since these Hose stations are Quality Related (QR) Note 3 was which states Valve is QR, Hose Station is Non-Safety Related. Figure 9.5-1 S5 was revised to remove the safety classification flag upstream of XVM041 05-FS.
