F-Canyon TRU Waste Repack Facility Perma-Con® System

Modification of the F-Canyon access bay (Cat 1 facility) to convert to a radiological containment area suitable for repackaging TRU waste materials.
Handling of standard large waste boxes and other heavy materials required cranes to be installed in the area.
Integrate the containment walls, support structures, gantry cranes, and air-locks into the access bay of an existing structure and meet seismic criteria.
Design air flow controls and paths to maintain progressively decreasing negative pressures across containment cells or zones while maintaining the design air exchange rates.
Large, air-tight doors between containment cells for material handling (SLB-II’s).
Validate the location of air control dampers to optimize air flow patterns.

3D models of the structure were prepared for integration and flow analysis.
Computational Fluid Design® air flow modeling performed to validate air flow through the facility.
Custom stainless steel bi-fold air-tight doors designed to facilitate contamination control (Pu238 highly active self migrating).
Three air-lock cells with material and personnel passages were integrated into the access bay of the canyon.
Site acceptance testing performed to ascertain air flow requirements were met.
