Testing was completed today on the NHC air and gas supply lines.  For each line a Staubli plug was installed on the fitting inside the hot cell, the line was charged with compressed air (50psi for gas lines #1, #2, and #3;  100psi for the air lines #4 and #5).  All connections inside and outside the cell were checked for leaks using Snoop including connections for the solenoid valves.  No leaks were found.  Correct operation of the solenoids was confirmed as well as correct plumbing (no lines crossed).
