Subject: NBI Upgrade Weekly Status 3/26/10
Al,

NBI Upgrade: For the NBI Duct design, initial vendor contacts have been made to determine a budgetary estimate for the rectangular bellows. Also, an estimate is being prepared to fabricate the bellows in our shop. A budgetary estimate for the large 40 inch circular bellows will also be pursued to include in the WAF update for the duct job. Additional work on the NBI armor tiles, supports, and analyses continues. Efforts continue on the NTC platform design and cost estimates. The most recent version of the job WAFs were went to each job engineer for the upcoming WAF review in April.

NBI Decon:  Extensive decon on the beam box and ion dump continues. Standing effluent water in the box floor has been syphoned. Remaining puddles have been collected using rags. Entry of the box by the Decon crew has started using full PCs and breathable air hoods.  Manual wipedowns of internal walls and shields has commenced. Ion dump decon continues on external shields and internal copper dumps. Outer shields have been removed to increase access to the back of the dump plate. The side louvers have been removed for greater access also. The louvers have been moved to the Source Shop decon room and placed in a fumehood for further decon detailing. A comprehensive survey of components is scheduled for the end of this month to support the upcoming Decon Peer Review that will be scheduled for the end of April. Remedial decon on the Test Cell floor and periphery continues to maintain areas.

Regards,

Tim
