Studying at aperture

At unit EC 20: This is part of the coolerset of the water and steam analyzing system.
The hot water and steam coming from the various systems have to be cooled first before it can enter the analyzing equipment.
This is done by a line, brached off from the main demineralised cooling watersystem.
As this system and it's equipment is hardly needed, cooling always has to be secured, so a special emergency cooling system is fitted.

We were walking around there, checking the state of preservation of the unit.
We saw some discrepancies....
