Water Shield

Description/Name: Water Shield in the FAARM Facility at the 4850' level
Planned use (be specific):
1. Primary function: provide common first-level gamma and neutron shielding for screening detectors and ultra-sensitive immersion tank
2. Temporary and permanent storage: will house screeners of various sensitivities, including alpha-beta counters, HPGe detectors, immersion tank
3. Sample and detector handling: accommodations for alpha-beta screeners, HPGe screeners, immersion tank
4. Jigs, fixtures, scaffolds, etc. necessary
  1. Monorail for hoisting samples into water tank
5. E & O activities
Occupancy:
1. Steady: See occupancy listed under screening spaces
2. 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)
1. 3 m shielding thickness
2. 2 m space between shield and cavern for egress and pipe
