Uranium and Phosphate in the Western Part of the Bonny Lake Mine, Polk County, Florida

Description: From abstract: During the month of May 1950, the Davison Chemical Corporation, under contract with the Atomic Energy Commission, drilled 24 phosphate prospecting holes in the western part of the Bonny Lake mine, in the SW NW4 and the NW*SW4 sec. 32, T. 29 S., R. 24 E., Polk County, Fla. The purpose of this drilling was to obtain a comparison between tonnage and grade of uranium in the phosphate as indicated by prospecting, and the tonnage and grade of uranium in the phosphate products recovered… more

Studies on the Removal of Radioisotopes From Liquid Wastes by Coagulation

Description: Technical report covering work completed on the removal of radioisotopes from water using a calcium phosphate floc as a carrier. This research was performed as part of the Health Physics Waste Disposal Research Section work on the removal of small quantities of radioactivity from large volumes of water. [From Abstract]

Capacity survey -- Separations Division

Description: Recent tentative production forecasts indicate that as much as 96.6 Kg plutonium, associated with 190 tons uranium, may be produced each month. The ability of the Separations facilities to process these materials is herein summarized. The Redox Production Plant capacity has been reasonably predicted at about 112 tons uranium per month; this rate assumes only that critical mass control is achieved by the limitation of the possible volume accumulation at any point, and that the product concentrat… more

Recovery of Plutonium from Slag and Crucible

Description: Slag and crucible can be dissolved satisfactorily by the Los Alamos method of total dissolution with nitric acid in the presence of aluminum nitrate. Extraction of 99% of the plutonium from total dissolution salted with aluminum nitrate was achieved by three successive contactings with 1/10 volumes of 30% TBp- AMSCO 125-90W. The TBPAMSCO phases contacted with leaching solutions salted with calcium nitrate must be scrubbed to remove calcium. Stripping with three 1/10 volumes of 0.1M hydroxylamin… more

The Valve-Actuated Pulse Column Design and Operation

Description: A countercurrent extraction column is described which employs timed solenoid valves and pressurized feeds to provide a pulsing action to disperse the phases. The steps in the pulsing cycle are independent and thus provide greater separation of the operating variables than is possible with conventional pulse columns. The column described is particularly useful as a resesrch tool for the study of extraction mechanism although a larger installation operating on the same principles should be quite … more

RDA No. DC-7 -- Capacity basis for increasing production from Redox -- 202-S

Description: The outstanding economy of the Redox process when compared with the BiPO{sub 4} process dictates that as much production as possible, and as soon as possible, should be shifted from the BiPO{sub 4} process to Redox (202-S). It is proposed that the capacity basis for the subject study be for as much as 200 tons of uranium and up to 105 kilograms of plutonium per month, assuming that facilities proposed for these capacity levels will not interfere with the operating flexibility of the plant, if i… more

Viscosity and Settling Rates of TBP Waste Metal Slurries as a Function of Shear

Description: This report follows work that is meant to determine the settling rate and viscosity of Hanford Waste metal slurry as a function of prolonged agitation and shear, and to repeat these determinations on a synthetic incubated material similar to that used in the acidification studies, HW-18367, and to make a direct comparison between the genuine and simulated wastes.

The Hydrolysis Products of Tributyl Phosphate and Their Effect on the Tributyl Phosphate Process for Uranium Recovery

Description: This report follows an investigation on how hydrolysis products of tributyl phosphate (such as dibutyl and monobutyl phosphoric acids, orthophosphoric acid and butanol) effect the tributyl phosphate process for uranium recovery.

THE USE OF CHELATING AGENTS FOR ACCELERATING EXCRETION OF RADIOELEMENTS

Description: Although the deleterious effects of exposure to ionizing radiation were first recognized and described over fifty years ago, the adequate treatment of these effects still remains a therapeutic challenge. At the present time, when increasing numbers of our population are being exposed to radiation because of the great increase in availability and use of radioactive isotopes and because of the potential exposure of much greater numbers of people to radiation following a possible atomic bomb burst… more

The Hydrolysis Products of Tributyl Phosphate and Their Effect on the Tributyl Phosphate Process for Uranium Recovery

Description: A study was made of the stability of tributyl phosphate (TBP) to acids, bases, and UO/sub 2/(NO/sub 3/su)/sub 2/ solutions, and of the chemistry of its decomposition products. The effect of such decomposition products on the extraction behavior of ion of MBP and lines the RAW analyzer and a subsequent reduction of feed flow rate in each case resulted in immediate reduction in losses, as evidenced by the polarographic results. In many such instances, several hours of operation at high waste loss… more

Analytical results on leachings from Nutsche Filters

Description: This report describes results of an investigation to determine whether plutonium nitrates and lanthanum compounds were being entrained on the filter aid and filter block of the Nutsche Filters in Cell 2 of Bldg. 231. Leach samples were analyzed for La, Pu, phosphate, fluoride, Pu{sup 240}, and Am. From the data the authors concluded that the holdup on the Nutsche Filter is due to insoluble plutonium compounds either filtered from solution, or more likely, formed on the filter. These compounds w… more
