ESS – Active Cell Viewing System

 The active cells facility is a windowless hot cell operated from the remote control room. The operator views of the
 equipment and components in the cells are only through the Viewing System cameras. Hence the viewing system
 must be highly reliable and provide a combination of wide area views (safety) and operational views (inspection,
 process monitoring, etc.)

                                                                                      W idely varying specs based on type of

Fabricated Assemblies Procurement

      Procurement will consist of 3 main parts:

      • Waste Storage Baskets.
      • Target Station Component Support Structures.
      • Large lifting adaptors.

      The exact nature of the procurement has not been finalised, however at present it is expected that the scope
      will be for the design and manufacture of all the items based on provided requirements specification.

      A Negotiated procedure is expected, that will allow for the scope and risk profile of the procurement to be
      adjusted. If the scope can defined well enough that an Open procedure can be used, this MAY be done.

Waste Storage Boxes

     • A parametric design will be needed to allow a range of Waste Storage
       Boxes (WSBs) to be manufacture by ESS as they are needed. The boxes
       will be placed within an existing shielded container approximately
       3mx2mx1m and will allow for:
         • A range of packing patterns from a single box up to six boxes.
         • Different shielding thicknesses ranging from 50mm up to 200mm.
     • A single WSB will be manufactured for use in the Acceptance Review
       of the Active Cells.
     • Expected requirements as follow:
         • When full, lifts from the lid using set twist lock pattern,
         • Removable sides.

Target Station Component Supports

     When Target Station components are introduced into the cell, a
     set of support structures are required to fix their location and
     provide stability. These include:
     • A receiving fixture to locate and support components as they
        are lowered into the cell.
     • Storage racks to support a number of Target Station
        components whilst they are waiting to be processed.
     General Requirements:
     • Interface with existing floor bolting pattern.
     • Stainless Steel construction (or very prescriptive painting
        rules).
     • Will have to support a maximum horizontal force TBD a fixed
        height from the floor
