When attempting to install the 1L07 Primary Return U-Tube, the cryomodule pressurized much faster than expected and to the point where the module pressure was above the allowable pressure for U-Tube operations. We attempted to blow the module down with no success and decided to remove the Primary Supply U-Tube to ensure the unplanned pressurization does not continue (in the event the JT valve leaks through). The shield supply valve is shut, and the module is expected to warm up to 300K for SRF to evaluate before we attempt another cooldown.
