The T2 cooling package was uncovered this morning and a leak was found coming from the Swagelok ball valve on the 3/4" target water outlet line. The water was coming from the stem of the valve, indicating that water was leaking through the valve packing, rather than at the fittings for the valve. The leak rate was approximately 1 drop every 5 seconds and a small puddle was visible on the top of the water reservoir. The water package was drained (samples were taken and given to RPG). After draining, the valve was replaced with a spare unit. The cooling package was refilled and restarted. The package was inspected while running and no visible water leaks were found. The flow rate through the resin can was adjusted from approximately 1.7 to 1.5 gallons per minute. |
