P&L 3.2 states: "When a Service Water Bay is removed from service in Modes 1-4, and the Service Water Pump fed from 'B' bus in the OPERABLE Service Water Bay is unavailable (23 or 24 SWP), then L.C.O 3.0.3 is applicable." An OPERABLE SW loop consists of two service water pumps powered from separate buses. With #2 SW Bay isolated (leak) and 24 SWP C/Ted, both SW loops are inoperable — TS 3.0.3 applies.
