The T1 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.

NOTE: the needle valve for demin flow control adjustment was behaving strangely - it needed to be tapped when loosening to increase flow in order for results to be observed. Suggest replacement next shutdown (2023) - a calendar reminder was set to do this.
