ABSTRACT:
A high quality HEPA filter is used in a vent for venting a chamber containing a radioactive material such as a plutonium slurry. The filter element includes a stainless steel wire mesh tube which supports a sintered stainless steel filter media thereon. The wire mesh tube has a stainless steel end plate completely closing one end thereof and a stainless steel end plate with an exhaust outlet opening at the other end. The outlet opening communicates with a hollow core defined by the stainless steel wire mesh tube. The sintered stainless steel filter media has its longitudinal edges joined by a tungsten inert gas weld and is also welded directly to the end plates by completely closed circular welds. An annular housing of stainless steel surrounds the filter element in spaced relation thereto and has an axial inlet. The gas to be filtered flows into the inlet, around the filter element and through the sintered stainless steel filter media before exiting through the exhaust outlet.
