Electrolytic dissolver for plutonium metal

Description: Laboratory tests have demonstrated that plutonium metal, as well as aluminum, stainless steel, Hastelloy C, and other alloys, can be electrolytically dissolved in nitric acid using the ''solution contact'' approach. Two sources of plutonium metal were evaluated, weapons' grade and a special reactor grade (42% /sup 240/Pu, 12% /sup 241/Pu) from Savannah River, both yielding a dissolution rate of approximately one gram per ampere-hour. A current flow of 150 amperes was attained at 12 volts (limit of the power supply) and higher current should be possible at increased voltage. Since no fluoride was used in the actual dissolution, glass and 304 stainless steel components provided satisfactory performance. Preliminary investigations on the sludge formed (less than 1%) during electrolysis showed it to be soluble in a low fluoride-high nitric wash. The proposed electrolytic dissolver is recommended to replace the present metal dissolution process for the following reasons: (1) eliminates button sectioning--entire buttons are dissolved; (2) eliminates metal burning; (3) eliminates powder handling; (4) eliminates PuO/sub 2/ dissolution; (5) reduces solids going to the recovery columns; (6) simple to operate; (7) relatively independent of plutonium metal source; (8) reduces operator time resulting in decreased cost and operator exposure; and (9) will directly dissolve many types of plutonium alloys and cladding materials.

Geothermal resources in California: potentials and problems

Description: The technology, cost and potential of geothermal resources in California are examined. The production of power from dry stream fields is expanding in Northern California, at The Geysers, at costs that compare favorably with alternate means of generation. The possibility exists that economic production of power can be started in the Imperial Valley, but numerous issues remain to be resolved; chief among them is the demonstration that commercially valuable aquifers indeed exist. The production of demineralized water from the geothermal fluids of the Imperial Valley depends, among other things, upon the identification of other sources of water for power plant cooling, or for reservoir reinjection, should it be necessary to avoid subsidence. It would appear that water production, without the income-producing capability of associated power generation, is not economically reasonable. The pace of geothermal development at the Geysers could probably be accelerated perhaps offering the opportunity for maintenance of adequate generating reserves should their nuclear construction program be delayed. The unknown factors and risks involved seem to preclude the Imperial Valley resource from being immediately effective in improving the power generation picture in Southern California. However, in the next decade, geothermal power could provide a useful energy increment, perhaps 10 percent of peak load. Associated water production could offer relief for the Imperial Valley in its predicted water quality problem. The pace of public and private development in the Imperial Valley seems incommensurately slow in relation to the potential of the resource. Geothermal power and water production is not intrinsically pollution-free, but appropriate environmental protection is possible.

Liquid metal bearing technology for large, high-temperature, sodium rotating machinery. Third topical report design data handbook for externally pressurized journal bearings including turbulence and inertia effects

Description: Design data for a Deep Pocket Hydrostatic Journal Bearing is presented. A wide range of possible operating conditions in the turbulent regime is examined. Both pressure flow induced turbulence and Bernoulli type inertia effects are accounted for in the generation of this data. Design data is presented for two bearing configurations, one selected for good stiffness characteristics, and the other with good balance between flow and stiffness. Tables of data are presented which provide load, flow, stiffness and damping of these bearings as a function of eccentricity ratio. In addition curves providing off-design information are presented, which may be used to evaluate tolerance effects and to study the performance of non-standard designs.

Acoustic flaw triangulation on a thin spherical shell: an analytical solution

Description: An analytical solution for acoustic flaw triangulation on thin spherical shells has been prepared. A FORTRAN program is provided which takes as input the differences in the arrival times of acoustic energy at the transducers and evaluates the spherical coordinates of the flaw. Only three experimental time differences need be measured. For this measurement, four transducers are required. One transducer is placed at (R, 0, 0) in spherical coordinates; the other three are spaced 90 degrees apart around the equator.

Lifetime measurements in /sup 38/Cl and /sup 40/K. [Lifetime, transitions, strengths, J,. pi. ]

Description: Electromagnetic transition rates within the /sup 38/Cl and /sup 40/K nuclei were studied through lifetime measurements with a double-coincidence variant of the Doppler-shift-attenuation method. In /sup 40/K the excitation energies (MeV) and measured mean lives (psec) are 0.800 (0.56 +- 0.13), 0.891 (1.53/sub -0.35//sup +0.40/), 1.959 (0.7 +- 0.5), 2.047 (0.49 +- 0.10), 2.070 (0.4/sub -0.2//sup +0.3/), 2.103 (0.54 +- 0.15), 2.261 (0.05 +- 0.05), 2.290 (0.33/sub -0.20//sup +0.40/), 2.291 (0.31/sub -0.12//sup +0.18/), 2.419 (0.55/sub -0.30//sup +0.85/), 2.575 (0.22 +- 0.10), 2.626 (0.32/sub -0.16//sup +0.40/), 2.731 (less than 0.120), 2.787 (0.13/sub -0.13//sup +1.00/), 3.110 (less than 0.14), 3.228 (0.04 +- 0.04), and 3.629 (less than 0.10). In /sup 38/Cl the lifetime results are 0.755 (0.30 +- 0.60), 1.309 (0.55/sub -0.20//sup +0.40/), 1.617 (1.5/sub -0.6//sup +1.2/), 1.692 (1.3/sub -0.3//sup +0.5/), 1.746 (1.1 +- 0.5), 1.785 (0.10/sub -0.08//sup +0.10/), 1.981 (0.26 +- 0.06), and 2.743 (0.05 +- 0.03). The energies of the low-lying (..pi..d/sub /sup 3///sub 2//)/sup +-1/ (..nu..f/sub /sup 7///sub 2//) shell-model states in /sup 38/Cl and /sup 40/K are known to be accurately related by the Pandya transformation. The (d/sub /sup 3///sub 2//)(f/sub /sup 7///sub 2//) model, when used with effective magnetic moments, can also approximately reproduce the /sup 40/K ground-state magnetic moment. However, the present work demonstrates that even when effective moments are employed, the (d/sub /sup 3///sub 2//)(f/sub /sup 7///sub 2//) model fails in its predictions of electromagnetic transition rates. The intramultiplet M1 transitions are observed to have allowed strengths, whereas the l-forbidden intermultiplet transitions to the states of the (d/sub /sup 3///sub 2//)/sup +-1/(f/sub /sup 7///sub 2//) configurations have strengths that are lower by two orders of magnitude. The one exception to this picture, namely the 1.617 ..-->.. 1.309-MeV transition in /sup 38/Cl, is discussed.

Study of the /sup 50/V nucleus with the (/sup 3/He,d), (/sup 3/He,. cap alpha. ), (/sup 3/He,p), and (/sup 3/He,p. gamma. ) reactions. [Angular distribution, 13 and 22 MeV, analog states, DWBA, J,. pi. , spectroscopic factors, angular momentum, transitions]

Description: The nucleus /sup 50/V with a ground-state configuration (..pi..f/sub 7/2/)/sup 3/(..nu..f/sub 7/2/)/sup -1/ was studied with the /sup 49/Ti(/sup 3/He,d)/sup 50/V, /sup 51/V)/sup 3/He,..cap alpha..)/sup 50/V, and /sup 48/Ti(/sup 3/He,p)/sup 50/V, and /sup 48/Ti(/sup 3/He,p..gamma..)/sup 50/V reactions induced by the /sup 3/He/sup + +/ beam from the tandem Van de Graaff at the Argonne National Laboratory. The angular distributions from (/sup 3/He,d), (/sup 3/He,..cap alpha..), and (/sup 3/He,p) reactions induced by 22-MeV /sup 3/He were studied with overall energy resolution widths of 20, 30, and 42 keV, respectively. The reactions (/sup 3/He,p) and (/sup 3/He,p..gamma..) were also studied at an incident energy of 13 MeV to obtain the ..gamma.. decay of /sup 50/V levels (including two 0/sup +/ isobaric analog states) in which the neutron-proton pair is transferred with zero angular momentum. The angular distributions of the charged-particle reactions were analyzed with the distorted-wave Born approximation (DWBA), and spectroscopic factors have been extracted for the one-nucleon transfer reactions. The two-nucleon transfer reaction (/sup 3/He,p) was analyzed with the DWBA on the assumption that the neutron-proton pair is transferred as a deuteron. The angular momentum L/sub np/ of the transferred deuteron is established for most of the levels, and the possibility that several levels might have spin and parity 1/sup +/ is discussed.
