TABLE 3.3 5 (Continued)
TABLE NOTATIONS (1) Diesel generator starting delay not included because offsite power available.
(2) Notation deleted.
l (3) Diesel generator starting and loading delays included.
(4) Diesel generator starting delay not included because offsite power is available.
Response time limit includes opening of valves to establish SI th and attainment of discharge pressure for centrifugal charging pues (where 1 cable). Sequen-tial transfer of charging pump suction from the VCT to the (RWST valves open.
then VCT valves close) is included.
(5) Diesel generator starting and sequence loading delays included. Offsite power is not available. Response time limit includes opening of valves to establish $1 path and attainment of discharge pressure for centrifugal charging pumps. Sequential transfer of charging pug suction from the VCT to the RWST (RW5T valves open, then VCT valves close) is included.
(6) The maximum response time of 48.5 seconds is the time from when the containment pressure exceeds the High High Setpoint until the spray pump is started and the discharge valve travels to the fully open position assuming off site power is not available. The time of 48.5 seconds includes the 28 second maximum delay related to ESF loading sequence. Spray riser piping fill time is not included. The 80-second maximum spray delay time does not include the time from LOCA start to "P' signal.
(7) Diesel generator starting and sequence loading delays included. Sequential trans-fer of chargin valves close) g pump suction from the VCT to the RWST (RWST valves open, then VCT is not included. Response time limit includes opening of valves to establish 51 flow path and attainment of discharge pressure for centrifugal charging pumps. 51 and RHR pugs (where applicable).
(8) Does not include Trip Time Delays. Response times include the transmitters. Eagle-21 Process Protection cabinets. Solid State Protection System cabinets and actua-tion devices only. This reflects the response times necessary for T)ERNAL POWER in excess of 50% RTP.
