System for measuring the uranium concentration of liquid effluents from the enriched uranium recovery facility at the Oak Ridge Y-12 Plant
A real-time, on-line monitor has been developed which can measure the uranium concentration of enriched uranium liquid effluent. The monitor uses the thorium L x-ray activity from the decay of $sup 234$U as the basis for the measurement. A sodium iodide/ thallium-activated scintillation crystal, optically coupled to a photomultiplier, is used as the detector. Evaluation results reveal that the limit of error over the uranium concentration calibration range is less than 1 wt ppM, and the lower limit of sensitivity is 0.50 wt ppM. This monitor cannot be used on a recovery facility which contains fission products. The monitor is installed in the Oak Ridge Y-12 Plant enriched uranium recovery facility and has been operating satisfactorily for some time. (auth)
