Engineering Operations
New hazards in the NTC associated with upgrade activities:• Ladders, scaffolds, man-lifts.• Cranes, rigging, forklifts.• Welding, burning, grinding.• Activated/Contaminated radiological work.• Electrical• Confined spaces.• Chemical use.• Eye hazards.• Uneven work surfaces.
A Health and Safety Plan (HASP) and Work Control Center Procedures in force.
• Address the control of hazards• Maintain configuration control• Coordinate required permits, technical procedures, etc.
Engineering Operations
Heavy Construction started this winter:• TF turnbuckles and clevis pads have been ground away.
Engineering Operations
• Space has been cleared for the 2nd Neutral Beam.
Engineering Operations
• Additional rib welding completed on the upper/lower domes.• New machine platforms installed.
Engineering Operations
• In-vessel metrology for NB armor installed and brackets welded in place.
• Passive plates were reinstalled in April.
Engineering Operations
• Outer TF coils #7 and #11 have been removed.
Engineering Operations
• Platform modifications/usage required for the TF work
Engineering Operations
• Bay J-K nozzles have been cut away
Engineering Operations
Upcoming Vessel Modifications:• Installation of In-vessel stiffeners at Bays J-K.
• Ongoing welding of new TF Clevis pads onto VV.
• Weld the new Bay J-K Cap onto the vacuum vessel in early July for the new NB port.
• Vacuum vessel cuts at Bay L in mid-July for MPTS.
• Vacuum leak checking
• Remove platforms at Bays J-K-L in preparation for neutral beam work
Engineering Operations
Neutral Beam work in the NTC:• Penetrations into NTC for cryo/electrical systems.
• Move Beam-Line into NTC in early August.
• Move lid/cryo-panels, 90” flange, torus and ion source interfaces into NTC in Aug/Sept
• Decontamination of both the NTC and the TTC
• Installation of beam-line systems and HVE’s throughout the fall.
Engineering Operations
Future NTC Access:• Upon completion of the NB equipment moves, we should be
able to provide greater access to the perimeter of the test cell.
• Access to the North door will remain limited while assembling/commissioning the NB HVE’s and transmission lines.
• Internal and External access to the vessel itself will remain restricted into the spring of 2013 due to ongoing welding of the umbrella legs, PF supports, etc.
