Source term reduction initiatives with the fastest return on investment (ROI) have proven to be those which implement enhanced filtration techniques.
Conventional mechanisms of filtration rely on the mechanical structure of the filter media to capture and retain contaminants. With filtration requirements in the reactor coolant system (RCS) at 0.1 microns (μm) simply adding more and finer material does not insure higher removal rates. In fact in many instances it has been shown to be counterproductive as the pressure losses due to the lack of permeability result in more frequent filter change-outs and higher costs not to mention increased risk of exposure from increased frequency of handling.
Even at sub-micron removal ratings, conventional filters rely on the physical structure of the filter media for capture and retention of contaminants. The principal...
Based on the standardized Mullen and Tensile tests, the nano-fiber filter media has exceptional robustness and strength advantages compared with the resin impregnated glass fiber filter media.
