Located south of OSF, they maintain glycol water outlet at 46°F and trip at 32°F (manual reset).
What happens to GW-V-11A/B chiller valves with 1X ATS in Emergency?
GW-V-11A/B chiller valves will NOT open.
What is the function of TSC Fans (AH-E-146)?
They operate at fast speed when AH-F-16 is in service, maintain slight positive pressure in TSC, and are used only when radiation is present as directed by the Emergency Plan.
What happens when 13.2kV power is lost in the OSF?
ATS transfers in 15 seconds (break before make), all loads are lost except PPC supplied by battery, and it returns to normal seeking after 330 seconds.
