North Linac u-tubes
We have removed all u-tubes from NL06, 07, & 08.
NL06 & 08 are still connected to guard vacuum for venting the remaining liquid (< 5% each). NL07 is disconnected from guard vac but is empty of liquid.
L-tubes were installed into the transfer line primary return bayonets for NL06 & 07. The RT valves are closed and cabled to facilitate next week's u-tube operations at CHL. NL08 RT is closed and decabled.
