F-Canyon TRU Waste Repack Facility Perma-Con® System
F-Canyon TRU Waste Repack Facility Perma-Con® System
Project Scope:
- 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.
Description:
- 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.
