Al,

NBI Management: Emphasis shifted to organizing cost and schedule development this week within the context of the technical content presented at the peer review.

NBI Decon:  Surveys to characterize tritium regrowth on the cleaned areas of the calorimeter are underway so decon of the calorimeter will resume next week. The D2 and guard vac system removals from the exterior of BL4 are complete. Efforts continue to arrange floor space and place the magnet, 90 inch flange, and lid stands on the East end of the Test Cell. The lid stand delivery from the shop to the Test Cell is being mapped out and arranged.

NBI Power and Control:  Work on N4 HVEs to disconnect internals is in progress.

NBI Duct, VV Port, and Armor:  Several parallel technical efforts continue: selecting turbopumps and checking on magnetic field environment for operation, assessing manufacturability of the Bay J-K cap, and studying the installation process to attach the cap. The beam power distribution study of both beamlines impinging on the relocated armor tiles is complete. Structural support of the armor at Bay H and available clearance inboard to the last closed flux service is being studied to improve ease of installation and maintenance of the armor panels.

NBI BL Services: Water and vacuum pump sizing and selection is in progress and will be folded into the cost estimate for BL services.

NTC Equipment Relocations:  The additional space at Bay I midplane port made available due to the shift in armor position is being studied for diagnostic use. The list of diagnostics relocations has been completed and reviewed to confirm that it is consistent with NSTX programatic needs. This detailed list and the list of electronics racks effected will now form the basis for cost and schedule estimates.


Regards,

Tim
