GATEVALVE OPEN OPERATION 4 AND ASSOCIATED OBSERVATIONS
A warm-and- and/or cool-and-vibration operation will be carried out to open the gate valve. A preparatory observation and actual vibrating trials are scheduled in September, 2025. In the event of a successful opening, commissioning and calibration observations will be conducted.
