Description/Abstract:
This document concerns the Metal Recovery Progress Report for the month of November 1953. During this month, the Metal Recovery plant operated at 89.9 percent time efficiency and processed an average of 328 kg (721 pounds) of uranium per operating day. A total of 8,846 kgs of uranium and an estimated 42 grams of plutonium were recovered during the month. The 10.1 percent down time was required to facilitate installation of 2 MR equipment. The composite uranium loss from the plant, which included all losses incurred in centrifuge cleanouts and solvent extraction, was 1.4 percent. The uranium loss resulting from solvent extraction was 0.3 percent. The fission product beta and gamma activities of the recovered uranium product were 0.5 and 34 percent, respectively, of natural uranium. The plutonium contamination in the recovered uranium was 27 ppb. The total metallic ion contamination in the uranium was 975 ppm. The main contaminant was iron (900 ppm) and was due to entrainment from the plutonium partitioning column, which will be modified during January to provide a larger deentrainment section. During November three shipments of uranyl nitrate product solution containing 6,959 kgs of uranium were transferred to the Y-12 Plant to be converted to uranium trioxide. A total of 76,866 kg of uranium was recovered from metal waste solutions up to November 26. Two shipments of irradiated slugs containing 1,694 kg of uranium were received from Brookhaven National Laboratory during November. Three shipments of waste material in the form of press cake sodium diuranate, containing 5,667 kg of uranium were received from Harshaw Chemical Company. A graph indicating the monthly uranium production of the plant for the year is included. Tables are also included.
