The T1 and T2 cooling packages were drained starting at 14:36, by 14:48 both expansion tanks had dried, meaning the draining rate for both tanks were ~80L/hr, generally it will only take 2 hours to fully drain the system.

Tritium samples were collected after allowing the system to drain for ~5 minutes to clear out water in the drain lines and actually collect samples from the reservoirs. The samples were passed onto RPG for analysis.

The drain valves on the cooling packages and in the BL1A tunnel is left open.
