Entry  Monday, March 14, 2022, 14:09, Adam Newsome, Maintenance, Target 2, Cooling, T2 cooling system: filled, tuned, leak-checked  
The T2 cooling system was refilled with water via the expansion tank until the tank level read approximately 38 cm. 
The system pump was restarted. All sensors displayed acceptable nominal values. Demin flow was tuned to 1.0 gpm.
No leaks or abnormalities observed - system running normally.
