Al,

NBI Upgrade:  Engineering work continues on adding design detail to the duct. Work has started on design layouts to evaluate altering platforms to access and maintain the NBI BLs in the NTC. Project management produced requested changes to cost and schedule profiles to match project and DOE guidance.

NBI Decon:  Decon continued on the lid using the sprayers with DI water. This technique is proving to be effective in reaching panel area behind the chevrons. The effort has moved from the exit end of the BL to the interior regions of the panels. Good results are being obtained. Since the break, decon has continued on calorimeter, 90 inch flange, and magnet. Some OMA disassembly has started also to remove shields. Surveys indicate that contamination levels did not come back up over the two week decon break indicating that there has been no regrowth on that time scale. HP support continues to be outstanding and keeps pace with the effort.

Regards,

Tim
