Description
The main cooling water line (1 meter diameter) for technical equipment at the Spallation Neutron Source (SNS) had a fitting begin to fail, resulting in a several tens of gallons per minute leak. Mechanics prepared an ingenious temporary repair while management discussed the option of turning off the system, which would have resulted in several days of downtime. When the fitting finally failed completely a short time later, the mechanics were able to implement their scheme and stop the leak while the accelerator continued to run. The repair held without issue until repairs could be made during the next extended outage. This poster/talk will discuss the temporary repair.
