====== Water Shield ======

  - Description/Name:  Water Shield in the FAARM Facility 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 
          - Monorail for hoisting samples into water tank
     - E & O activities 
  - Occupancy:
     - Steady: See occupancy listed under screening spaces
     - Peak: See occupancy listed under screening spaces
  - Adjacencies (list/distance): See adjacencies listed under screening spaces
  - Space size (gsf and/or WxLxH):  approximately 2330 m^3 (excluding space beneath first floor which is approximately 1160 m^3)
     - 3 m shielding thickness
     - 2 m space between shield and cavern for egress and pipe
