Al,

NBI Management: Preparations for the peer review next week continue on all jobs. 

NBI Decon:  D2 and guard vac removals are nearly complete. Decon wipedowns of the calorimeter continued with variations to test techniques and protective equipment. A complete HP survey will take place today to evaluate progress.

NBI Relocation: While the NSTX NBI calorimeter was being removed for maintenance, measurements were taken to contribute to the hieght rackup for beamline travel over the south high bay shield wall.

NBI Power and Control:  Additional details were considered and added to the evaluation for locating the High Voltage Enclosures in the NTC.

NBI Duct, VV Port, and Armor:  Concerns about locating and mounting the Bay J-K Resistive Wall Mode coil around the proposed vacuum vessel weldment required some changes and these ideas are being factored into the models. Development of the TVPS system is also underway.

NBI BL Services: Concepts are complete. Layouts are complete. Presentation materials for next week are in progress.

NTC Equipment Relocations:  Lists of changes have been prepared for presentation next week. A rigorous review with Diagnostics is planned.


Regards,

Tim
