-====== Water Shield ====== 
- 
- 
-  - Description/Name:  Water Shield at the 4850' level 
-  - Planned use (be specific): 
-     - Primary function: provide common first-level gamma and neutron shielding for screening detectors and ultra-sensitive immersion tank 
-     - Temporary and permanent storage:  will house screeners of various sensitivities, including alpha-beta counters, HPGe detectors, immersion tank 
-     - Sample and detector handling:  accommodations for alpha-beta screeners, HPGe screeners, immersion tank 
-     - Jigs, fixtures, scaffolds, etc. necessary  
-          - 30 ton overhead crane; smaller cranes 
-     - E & O activities  
-  - Occupancy: 
-     - Steady:  NA 
-     - Peak:  NA 
-  - Adjacencies (list/distance):2 m space between shield and cavern for egress and pipes 
-  - Space size (gsf and/or WxLxH):  approximately 2330 m^3 (excluding space beneath first floor which is approximately 1160 m^3) 
-  - Experiment Systems: 
-  - Shielding: 
-  - Floor load (PSF):   
-     - perimeter:   
-       - water: approx. 80m x 20m x 3m is 4.8 x 10^6 kg or 10.6 x 10^6 lb (not up-to-date as of Dec. 22, 2009) 
-       - SS:
