This is a technical drawing/blueprint for a J Cell Mechanical Draft Hybrid Wood Cooling Tower for the NIST Research Reactor Project. The document is a BDT Engineering design specification showing a transverse section view of the cooling tower structure.

The drawing depicts a complex mechanical cooling system for NIST's research reactor facility, featuring detailed specifications for wood construction with galvanized steel components, heat exchangers, drift eliminators, spray systems, and various mechanical controls. Key structural elements include motor-operated galvanized steel drift reduction equipment, a fill section with multiple chambers, an HV hose connection system, maintenance platforms at bundle areas, and a complete piping network for water distribution and drainage. The cooling tower incorporates multiple safety and operational features including control valve systems, distribution piping marked for polyethylene or metal construction, and structural bracing systems. The drawing references BDT Contract No. CT-1047/PI22 and includes dimensional specifications, material callouts with triangular hazard warning indicators for critical notes, and revision documentation showing various design iterations and approvals. This is a working engineering document supporting the procurement and construction of specialized cooling infrastructure for a federal research facility.
