====== Water Tank Engineering Issues ======
==== Design-integration of the following ====
  * Requirements
  * Design Criteria
  * Codes and Standards including EH&S
  * Shielding material 
  * Structural material 
  * Adaptability for possible remodeled shield configuration or for R&R of equipment
  * Fabrication-Vendor surface shops and/or 4850 level fabrication
  * Material transport-Dependant on final Yates lift configuration
  * Assembly integration 
  * Maintenance
  * Liquid Processing 



==== Shielding Material ====
=== Liquid ===
  * Type
  * Containment
    - Module size
    - Shine prevention
  * Liquid circulation and processing
    - Air removal 
    - Breech containment
	
=== Plastic ===	
  * Type and implementation method- Availability
    - Solid panels 
      * Cast 
      * Built up from thinner Plate or castings
    - Sprayed in place 
      * May be less dense than cast material
      * Could be a Toxicity problem in the Module/drift –EH&S issue

==== Structure ====
  * Minimum steel mass
  * Walls
    - Vertical and Lateral stability
  * Roof
    - Modular
    - Flexibility for introduction and heavy maintenance of equipment inside the shield
  * Floor 
    - Support of screeners and Immersion tank
