GForce and its manufacturing partner were contracted to provide design, fabrication, testing, and on-site support for the BNI Waste Treatment Plant WESP.  The WESP will process the vitrification process offgas from the melters and remove entrained particulate and acid gases from the airstream.

The scope of work for this project includes the design, fabrication, and testing of two (2) Low Activity Waste (LAW) WESPs and two (2) High Level Waste (HLW) WESPs.  This design incorporates innovative features where a commercially available precipitator was combined with the nuclear industry standards to produce one of the “first of its kind” radioactive particulate and acid gas removal systems.  The WESPs are ASME Boiler and Pressure Vessel code, Section VIII, Division 1 vessels that are rated and stamped for 15 psi internal pressure and 14.7 psi external pressure.

In addition, the WESPs seismic analysis and design conforms to the 1997 Uniform Building Code (UBC) Seismic Category SC-3 and the acceptance criteria satisfies the requirements of ASME Section III, Division 1.  The vessels are constructed from the most corrosive resistant iron-base austenitic stainless AL-6XN Alloy with high strength at elevated temperatures.
