Radioactive liquid nuclear wastes are processed and treated within____________________?
Show answer Hide answer
Answer: C. Pulsed column extractor
Explanation
Pulsed column extractors are widely used in nuclear reprocessing plants. They handle radioactive liquid wastes efficiently without mechanical moving parts inside. Liquid-liquid extraction separates valuable actinides from fission products safely. Solvent extraction processes separate chemical species using immiscible liquid phases. Pulsed columns enhance mass transfer by oscillating the liquid contents vertically. Nuclear waste processing requires highly reliable equipment with minimal maintenance needs.
Spent nuclear fuel recycling facilities rely on liquid-liquid extraction technology. Remote operation capabilities make pulsed columns ideal for hazardous radioactive environments. Strict safety regulations govern the design of nuclear chemical processing units. Mixer-settlers are used in various industries but lack the specific pulsing action. Rotating-disc contactors have internal moving shafts unsuitable for high radiation. Bollman extractors are designed for solid-liquid leaching of oilseeds, not liquid wastes.
