- Normal contents of these tanks is clean condensate. If there were a Reactor Coolant System leak inside containment,
, some evaporated reactor coolant could condense on the containment cooler coils and drain to the Containment Cooler i Condensate Tanks. However, containment isolation valves to the Containment Cooler Condensate Tanks would close on l high containment radioactivity.
