1 of 1 Unit 2 ESF ACTUATION SETPOINTS AND TIME DELAYS TO ACTUATION ASSUMED IN NON-LOCA SAFETY ANALYSES ESF Actuation Function Nominal Setpoint Limiting Actuation Setpoint Assumed In Analyses Time Delay (Seconds)

Safety Injection (SI)

- Low pressurizer pressure 1815 psig 1700 psig 27 w/offsite power 1 37 w/o offsite power 2

- Low steamline pressure 600 psig 344 psig 27 w/offsite power (1) 37 w/o offsite power (2)

Auxiliary Feedwater (AFW)

- Low-low steam generator water level 21% of narrow range span 0.0% of narrow range span 603 High-high steam generator Level Turbine Trip 67% of narrow range span 82% of narrow range span 2.5 Steamline Isolation on low steam line pressure NA4 NA (4) 115 Feedwater Line Isolation on high-high steam generator water level 67% of narrow range span 82% of narrow range span 11 6 Feedwater Line Isolation on low steam line pressure NA (4)

NA (4) 8 (6) 1 Emergency diesel generator starting and sequence loading delays NOT included. Offsite power available.

Response time limit includes opening of valves to establish safety injection (SI) path and attainment of discharge pressure for centrifugal charging pumps. Sequential transfer of charging pump suction from the volume control tank (VCT) to the refueling water storage tank (RWST) (RWST valves open, then VCT valves close) is included.

2 Emergency diesel generator starting and sequence loading delays included. Response time limit includes opening of valves to establish SI path and attainment of discharge pressure for centrifugal charging pumps. Sequential transfer of charging pump suction from the VCT to the RWST (RWST valves open, then VCT valve close) is included.

3 For Loss of Normal Feedwater and Loss of Offsite Power to Station Auxiliaries occurrences, the delay time assumed is 60 seconds from the initiation of the signals. For Feedwater Line Break event, the delay time assumed is 600 seconds (10 minute operator action delay) from the initiation of the break.

4 Not Applicable 5 Steamline isolation total delay time includes valve closure time, and electronics and sensor delay. Technical Specifications require 8.0 second valve closure time.

6 Feedwater Line isolation total delay time includes valve closure time and electronics and sensor delay time.
