Collaboration Staff Members,
PORTAKAMPS
Portakamp skirting has been removed as preparations continue for removing the portakamps which are bound for the railhead or scrap. Portakamp 150 which is the Purdue east stand alone unit has been emptied out per an earlier mail message and is basically ready to be moved. Weeds and brush are being removed from near all portakamps for easier access to continue preparations for removal from the area. Contents of two attached collaboration portakamps (056 and 046) are gradually being identified and being addressed appropriately. These need to be cleaned out by Aug 8.
GAS SHED
The gas shed has been emptied of its contents except for the specialty gases for which a new home is being sought. The gas shed power will be disconnected in the very near future.
DETECTOR ROOM
Several items were removed from the detector room while the accelerator was down this week. These items were radiation surveyed and identified as scrap and are with other scrap items in the C0 parking area. It is expected that scrap items will be picked up in the very near future. What remains in the detector room is an empty relay rack which will be scrapped at the next access opportunity and a magnet approximately 8'x 4-1/2' x 16" deep. Any information pertaining to this magnet and its' future would be appreciated. Plastic and coper gas lines will all be scrapped. The last remaining items are the cables.
CABLES
1. On Wednesday August 20, I will begin cutting cables/fibre optics at portakamp number 056. This will allow the removal of this portakamp shortly after.
2. On Wednesday September 3, I will be removing the cable/fibre segments in the spectrometer room.
3. The remaining cable/fibre segments in the detector room will be removed during the next available access opportunity.
A few of you have expressed concern about saving some of the cables however, as I've mentioned in the past it is imperative that the extensive resources (manpower/training/ES&H concerns needing detailed thought and implementation) required to salvage all or some of these cables in a safe manner and not hamper/complicate the decommissioning/demolition effort of C0 would not be cost affective. The cables are used and many ends will have radioactivity level of low class 1 and the labor needed to remove these with minimal damage will be time intensive. The safest way to salvage these cables is with personnel who are properly trained in this type of activity. I know of no one who is available at this time or in the near future.
