The charcoal filtration advantage: Liquid radwaste reduction at the South Texas Project
- Electric Generating Station, Wadsworth, TX (United States)
To reduce the amount of liquid radwaste discharged to the on-site cooling reservoir and to control the rising costs for solid radwaste disposal, the South Texas Project Electric Generating Station (STPEGS) embarked on an effort in mid-1992 to improve the efficiency of liquid radwaste processing. As compared to 1991 data, STPEGS achieved a 21-fold reduction in curies released, decreased the volume of liquid radwaste processed to less than half, and reduced by one half the generation of solid radwaste media from this processing. Improvements made in the third quarter of 1994 focused on improving the efficiency of the charcoal filtration process by using techniques presented in papers at the 1994 EPRI Radwaste Conference. These operational improvement techniques reduced the monthly radwaste curie effluent by approximately 50%, allowed the use of only one charcoal bed versus two, and resulted in radwaste processing which requires an infrequent use of demineralization. This paper will describe the various approaches and lessons learned during this continuing journey toward {open_quotes}world class{close_quotes} performance.
