Laboratory-scale evaluations of alternative plutonium precipitation methods (open access)

Laboratory-scale evaluations of alternative plutonium precipitation methods

Plutonium(III), (IV), and (VI) carbonate; plutonium(III) fluoride; plutonium(III) and (IV) oxalate; and plutonium(IV) and (VI) hydroxide precipitation methods were evaluated for conversion of plutonium nitrate anion-exchange eluate to a solid, and compared with the current plutonium peroxide precipitation method used at Rocky Flats. Plutonium(III) and (IV) oxalate, plutonium(III) fluoride, and plutonium(IV) hydroxide precipitations were the most effective of the alternative conversion methods tested because of the larger particle-size formation, faster filtration rates, and the low plutonium loss to the filtrate. These were found to be as efficient as, and in some cases more efficient than, the peroxide method. 18 references, 14 figures, 3 tables.

Separations areas effluent treatment: The preparation of a simulated effluent for system development and testing (open access)

Separations areas effluent treatment: The preparation of a simulated effluent for system development and testing

A fundamental parameter in the design of the Effluent Treatment Facility (ETF), the effluent composition, has recently been investigated by analyzing samples from both separations areas. As a result of this characterization program, we can now project the composition of the ETF feed stream. The anticipated feed composition is presented here for the purpose of making system projections; and a formula is provided for a simulant to use in testing evaporation, filtration, and reverse osmosis (RO) equipment. The components in these waste streams which present potential fouling problems for reverse osmosis are calcium, iron, manganese, barium, and aluminum, in combination with carbonate, silicate, and sulfate. Organics, probably in the form of TBP and kerosene, are also present in the combined effluent, which is otherwise dominated by NaNO{sub 3} and HNO{sub 3}. 3 refs., 3 tabs.

Materials compatibility with the volcanic environment. Final report (open access)

Materials compatibility with the volcanic environment. Final report

Attempts were made to run materials compatibility, volcanic gas collection, and heat transfer experiments during the 1977 Kilauea eruption. Preliminary results from the recovered samples showed that Fe, Ni, and Fe-Ni alloys were the most heavily oxidized. The Mo and W alloys showed some attack and only neglible reaction was seen on 310 stainless, Hastelloy C, Inconel 600, Inconel 718, Rene 41, and Nichrome. Results are qualitative only. (DLC)

Reference klystron output phase values for the first ten linac sectors (open access)

Reference klystron output phase values for the first ten linac sectors

The purpose of this note is to provide phase reference values for klystrons in the first ten linac sectors to be used as tentative start-up values next September and to point out the degree of long term phase stability of the klystrons as well as the possibility of implementing closed loop feedback stabilization.

Test Results on D-12A-2 (open access)

Test Results on D-12A-2

The purpose of this report is to describe the recent tests of D-12A-2. The tests of D-12A-2 began on April 30 and ended on May 8. The unusually long test period was a result of an extensive series of magnetic field measurements in which we attempted to determine the shielding affects of a sextupole compensating coil and the decay of the currents induced in this coil. This report is short, but much of the data from the tests are included or summarized. We begin with a description of the coil and conductor, continue with the training history, the results of magnetic measurements, including the use of a sextupole compensating coil and then describe the results of heater induced quenches including estimates of axial and transverse quench propagation velocities.

Ethylene Dibromide: Regulatory Background (open access)

Ethylene Dibromide: Regulatory Background

Much attention has recently been focused on the chemical ethylene dibromide (EDB). This chemical has been widely used in leaded gasoline, and has also been used to treat grains, citrus and other crops. It has been found in foods and in groundwater. This paper examines the possible health effects of exposure to EDB, as well as its regulation. The possible health effects and regulation of various chemical and physical alternatives to EDB are also examined. This paper concludes with some policy considerations pertinent to EDB.
