The existing technology of lanthanide-actinide separations is discussed with emphasis on the difficulties to be expected if the currently practiced separation methods were to be applied to waste partitioning. All of the workable methods known are noted, and three out of the four have seen many applications for the last 20 to 25 years at our Laboratory and elsewhere. The fourth, developed at ORNL 16 to 17 years ago, has been applied to waste partitioning in Germany. Each of these methods depends upon complexing the actinides to a slightly greater extent than the lanthanides with either Cl/sup -/, SCN/sup -/, or aminocarboxylic acids. The separation of the complexed ions is accomplished with either liquid or solid ion-exchangers and, in principle, either can be used interchangeably.

The Shock Wave Data Center of the Lawrence Livermore Lab collects and disseminates P.V.E. data obtained with shock waves. It has been in existence since 1964. An extensive number of papers reporting shock data had become available by that time. This was so in spite of the fact that the technology was developed only during the 2nd World War. Collection and partial evaluation of this data was therefore of value to facilitate its use by our laboratory and others who were involved with science and engineering in the high pressure field. The pressure range of the data collected is quite extensive and extends from 1 MPa to 1 TPa. One very important difference between shock wave compression data and those obtained with static presses must be emphasized, since it is often not fully appreciated. The pressure-volume locus of shock wave states (Hugoniot), which is obtained by passing increasingly stronger shocks into samples with the same initial state, rapidly increases in temperature as the shocks get stronger and the pressure and compression get higher. As a consequence, this Hugoniot locus must have a lower compressibility than isotherms obtained under static conditions. In fact, if porous or otherwise expanded samples are used, …

The work described was directed toward the demonstration of the practical feasibility of the Floating Substrate Process for the growth of silicon sheet. Supercooling of silicon--tin alloy melts was studied. Values as high as 78/sup 0/C at 1100/sup 0/C and 39/sup 0/C at 1200/sup 0/C were observed, corresponding to supersaturation parameter values 0.025 and 0.053 at 1050/sup 0/C and 1150/sup 0/C, respectively. The interaction of tin with silane gas streams was investigated over the temperature range 1000 to 1200/sup 0/C. Single-pass conversion efficiencies exceeding 30% were obtained. The growth habit of spontaneously-nucleated surface growth was determined to be consistent with dendritic and web growth from <111> singly-twinned triangular nucleii. Surface growth of interlocking silicon crystals, thin enough to follow the surface of the liquid and with growth velocity as high as 5 mm/min, was obtained. Large area single-crystal growth along the melt surface was not achieved. Small single-crystal surface growth was obtained which did not propagate beyond a few millimeters. The probable reason for the polycrystalline growth is the poisoning of the growth interface by impurities.

Medium- and low-resolution field-ionization and high-resolution 70-eV electron-impact mass spectral data were obtained for thirty-eight gel permeation chromatographic (GPC) fractions obtained from a coal-derived liquid. Empirical formulas were deduced from the high-resolution electron-impact data. The field-ionization data were acquired for eventual calculation of quantitative distributions for the coal-derived liquid. The field-ionization mass-spectral data obtained for the GPC fractions from a Synthoil sample are being converted into quantitative compositional data. In conjunction with subcommittee ASTM D-2, a blend of aromatic hydrocarbons obtained from twelve crude oils was analyzed.

In a general high-beta guiding-center MHD equilibrium of an anisotropic minimum-B mirror-trapped plasma, stability is determined by the sign of the Kruskal-Oberman energy variation. The energy variation is given for near-marginally-stable line-localized perturbations, and within a positive factor. A brief theoretical discussion of various instabilities for different conditions is given. (MOW)

This report summarizes the economic and financial conditions pertaining to geothermal electric power plant utilization of geothermal fluids produced from the Roosevelt Hot springs area of Utah. The first year of electric power generation is scheduled to be 1982. The non-resource facilities will be called ''surface facilities'' and include the gathering system, the power plant, the substation, and the injection system.

In more than 17 years of studying underground nuclear explosions, LLL has developed containment procedures that include a stemming plan. Stemming plans can be divided into either layered or continuous forms. There are marked differences between standards for these forms. The materials used in the continuous plan must meet more stringent specifications; as a consequence, they are more expensive. Both plans have been successful since the Baneberry Event. Both plans must meet the following requirements: provide a plug sufficient to match the overburden density of earth; contain radioactive gases at the lowest possible depth; minimize the generation of noncondensable gases (such as CO/sub 2/); minimize gas flow rates during the early post-detonation stages when cavity pressure is high; and be compatible with the experiment and its diagnostics. LLL experience in developing containment procedures is reviewed, and the reasons for the adoption of LLL's continuous stemming plan are reported. (LCL)

It is the unanimous conclusion of the Ad Hoc Committee that radioactive waste can be stored in salt and underground repository sites sufficiently removed from natural and/or man-made dissolution areas so that the waste will not be liberated during its hazardous period at projected rates of future salt dissolution. To ensure long-term isolation of radioactive waste in salt formations, specific recommendations are given for needed research concerning (A) General Principles, (B) Basinal or Regional Studies, and (C) Site-Specific Studies, each stated in sequence of priority.

This is an agreement between the National Accelerator Laboratory and Professor I. Pless of MIT representing the experimenters to provide selected instrumentation for the beam to the 30-inch bubble chamber, and to use the hybrid chamber for an experiment. This document contains an enumeration of the major items needed for the proper execution of Experiment No. 154 as expressed in the proposal for the experiment, subsequent correspondence, and the draft agreement. This agreement covers phases I and II of the experiment. In Phase I the experimenters will design, construct and bring into operation a complete upstream proportional chamber system. This system will tag incident beam particles as to type by correlating the Cerenkov signals furnished by NAL with the proper incoming particle. In addition, the system will measure the position of the incident particle which passed through the momentum slit. The system will contain three proportional wire chambers (3 planes each) which will provide data suitable for defining the incident beam both as to position and angle. The experimenters will furnish the computer, magnetic tape units, programs, and all necessary readout and interface hardware. When the system is installed, debugged, documented and completely functional, it will be turned over to …
