NSTX BL2 Upgrade: Management Activities

1
NSTX BL2 Upgrade Management Activities

• CDR Requirements Outline generated with
  assignments.
• Job numbers opened for major elements of NBI
  upgrade.
• Initial Work Planning Forms submitted and
  approved.
• Some Engineering resources (Cog Engineers
  designers) identified and assigned work,
  including the BL Services and Cryogenics
  Mechanical Engineer from original BL Upgrade.
• More to go to cover all of the major elements.
• Comprehensive NBI Upgrade Task List generated.
• A General Arrangement drawing update of the NSTX
  Test Cell has been requested for use with NBI BL2
  Upgrade requirements.
• The Head of PPPL Hoisting and Rigging has been
  requested to evaluate best methods for the NBI
  Beamline Relocation effort to move the
  refurbished BL from the NBI Test Cell to the NSTX
  Test Cell and install it on its support stand.
• Resources and scope identified and costs
  estimated for FY09 effort to arrive at CDR by
  11/09.
• Design work and Decon effort on track so far for
  CDR in November.

NSTX BL2 Upgrade Power Systems Controls

• Power systems from TFTR BL4 A,B, C have been
  chosen for NSTX NBI Upgrade BL2 due to their
  proximity to existing systems and controls
  already in use.
• Evaluation of the routing of cables and trays has
  begun with some very promising options already
  discovered. (Existing routing though the MER
  looks complicated and expensive so better routes
  are being sought.)
• Evaluation of the removals of N4 High Voltage
  Enclosures from the TCB has begun. This work will
  be slated for an NSTX outage when active water
  lines can be shut off.
• Power and Controls Engineering assignments have
  been made and detailed estimates started.
• Preliminary contacts with vendors of the high
  voltage triax and connectors indicate that these
  components are available for purchase.

NSTX BL2 Upgrade NBI Decon Activities

• Initial BL Tritium surveys characterizing BL
  completed. Ongoing surveys will be performed
  periodically to assess progress.
• Airborne and smearable contamination is
  reasonable and as expected
• External smears completed to allow work.
• NBI Test Cell access has been reviewed and
  restricted for Decon effort.
• Three procedures have been completed for removals
  and pumpout.
• All three transmission lines have been removed
  and lowered to TCB for storage.
• Lid Stand engineering sketches have been started
  to fabricate a new stand.
• Pumpout of the BL to the stack with air vent of
  the beamline to begin air exchanges is imminent
  and may start as soon as next week

• Modeling has begun to lay out BL2, the Beam Duct,
  the TVPS pumpduct appendage, and Bay K Vacuum
  Vessel modifications for wider aiming angles.
