Subject: t2 m9 port blank off 

1. Blank off installed 11:40 with Dan McDonald, east spring ear looks 'deeper" than west.

- Reused all hardware from last install, most active hardware was around 10 mSv/h on contact

- Zero point was at the 1/2 turn marker pen mark

- Installed at 1.5 turns from "finger tight" zero.

 

2. Spring eye zero set on a spare flange with spare pins.

- backed off 1/2 turn then mounted to exit port.

- tightened .5 turn to get to zero, then 1.5 turns on east and west sides to seal, in increments of .5 turns alternating.

 

3. Called Edi to start pumping on T2 at 12:50
