NBI Decon:  Test Cell purge air quantities have been affected by the need to purge the NSTX Test Cell more aggressively due to bakeout. Additional mopping and wipe downs of equipment are  being performed to maintain areas in the Test Cell. Decon continued this week on lid and box. HP and ERWM support continues to be outstanding and keeps pace with events. So far, a total of 6 barrels have been solidified for disposal. Decon continued this week on lid and box. The sprayer is now being used at the 90 inch flange opening instead of from lifts beside the box. The box sprayer uses 25 gallons per decon pass. Most of the effluent water can be drained but  a slight amount of residual remains in the beamline and will have to be addressed prior to box entry and wipe downs of the interior. Plans to decon the ion dump are finalized and will begin with hands on wipe downs of the exterior and louvers. New breathable air system air lines were ordered to be used on the ion dump decon; hands on wipedowns of the ion dump will start when the air lines arrive. Evaluation of survey results are in progress in preparation for the Decon Peer Review planned for April 2010.
