CP4 LN2 vaporizer work

John, Chandra

21:10-21:45 UTC

We cut the locks on CP3, CP4 bottom LN2 draw valve cover and broke the fitting downstream of LN2 vaporizer on CP4. Pressure in GN2 line blew down, and we capped off the downstream line. Pressure/leak testing of vaporizer will continue tomorrow when the right size ASA flange arrives.
