Re Procedure E1000603.

Yesterday we pulled the Dome from BSC6 at MidY.  We were unable to pull the Dome through the Cleanroom Ceiling Sock.  So after struggling for some time we decided to just pull the softroof off the cleanroom and reinstall after the dome was down.  Other than the delay of trying for a while and then reinstalling the sock, it wasn't too big a deal.

The inner O-ring was stuck for just maybe 6" and presented no problem.

Today we installed the work platforms and generally felt very comfortable working on the ends.  It was relatively easy to step around on the side and had plenty of room to make the connections there.  

The PISI came free of the Support tubes at 6300lbs and fully suspended load was 6410.  It slipped out from between the Support Tubes with no encouragement.  We did find we had too little headroom and re-landed the assembly to remove the Load Cell.  We then connected the lifting rig Master Links directly to the Crane Hook.  If we lowered the Cleanroom by maybe 12", we'd have enough clearance to leave the Load Cell in place.

Laydown of the stack needs more shimming than we planned.  We had ~14" of stacking and will have 16" ready next time.  This required we lower the Support Table further and the chains did mar up the top of the Down-Tube Al.

We replaced the Dome and this time we prepositioned the regular BSC Sock on the Dome.  Once the Dome was over the cleanroom, the SEI softroof was removed, the dome lowered and the Softroof connected to the Cleanroom.  No real issues connecting the Dome.

Thanks to the great crew!  Hugh
