Brookhaven National Laboratory, in order to provide technical information needed by the US Nuclear Regulatory Commission to evaluate the adequacy of near-surface disposal of decontamination wstes, has begun to study the leachability of organic reagents from solidified simulated decontamination wastes. Laboratory-scale cement waste forms containing EDTA, picolinic acid or simulated LOMI decontamination reagent were leach tested. Samples containing an organic reagent on either mixed bed ion-exchange resins or anion exchange resins were tested. A fixed interval leach procedure was used, as well as the standard procedure ANS 16.1. The leachability indices measured for the release of the acid from resin/cement composites are: 10.1 for EDTA on mixed bed resins; 9.1 for picolinic acid on mixed bed resins; 9.2 for picolinic acid on anion exchange resins; 8.8 for picolinic acid in forms containing simulated low oxidation metallic ion (LOMI) reagent on mixed bed resins and 8.7 for picolinic acid in forms containing simulated LOMI reagent on anion exchange resins. The leachability indices measured varied with leach time and the data indicate that the release mechanism may not be simply diffusion controlled. 5 references, 2 tables.

A cement-based waste form, ''saltstone'', has been designed for disposal of Savannah River Plant low-level radioactive salt waste. Laboratory and field tests indicate that this stabilization process greatly reduces the mobility of all of the waste constituents in the surface and near-surface environment. Bulk properties of this material have been tailored with respect to salt leach rate, permeability, and compressive strength. Microstructure and mineralogy were characterized by SEM and X-ray diffraction analyses. Compressive strength was found to increase as the water to cement ratio decreased. Porosity and mean pore size increased with increasing water to cement ratios. Bulk diffusivities of the various ions dissolved in the pore solutions were also found to increase as water to cement ratios increased. This paper discusses the test results.

Abstract: At the Savannah River Plant (SRP), a process has been developed for immobilizing high-level radioactive waste in a borosilicate glass. The waste is currently stored as soluble salts and insoluble solids. Insoluble waste as stored requires further processing before vitrification is possible. The processed required have been developed and demonstrated with actual waste. They include removal of aluminum in some waste, washing soluble salts out of the insoluble waste, and mercury stripping. Each of the processes and the results with actual SRP waste will be discussed. The benefits of each step will also be included.

Results are reported for an ongoing effort to optimize D/sup +/ beam production by the MATS-III ion source used at RTNS-II. The characteristics of the source have been determined. Particular attention was paid to the extraction geometry and plasma production. The plasma spatial and temporal uniformity has been examined. The seven aperture triode geometry has been varied to optimize neutron production. This includes beamlet steering and electrode gapping as well as aperture shaping. 4 references, 4 figures.

The Rotating Target Neutron Source (RTNS-II) facility produces 14-MeV neutrons for materials damage studies. Initial operation for irradiations, which occurred in 1979, began with a neutron source strength of 10/sup 13/ n/s utilizing one of the accelerator-based neutron sources. Details are given on improvements which have resulted in both increased neutron production and neutron source strength and improved control and monitoring. 8 references.

Fenton Hill Hot Dry Rock Geothermal Site Well EE-3 was designed and completed to function as a completion of the reservoirs with the injection well, EE-2, progressed it become evident that it would be desirable to fracture in EE-3 as well to obtain a flow connection between the wells. Unfortunately, the 9-5/8'' od production casing in EE-3 had been pretensioned to 885,000 lbs to accommodate its intended service as a hot water production well. Cool-down of the casing was thus limited to only 11/sup 0/C (20/sup 0/F) to keep the stress in the top joints of the casing below the minimum yield stress, or else the pretension had to be released. Before incurring the risk and expense required to release the tension, fracturing experiments were performed to evaluate the use gaseous nitrogen and 75% quality nitrogen-gel foam as insulating media in an annular wellbore configuration, i.e., the nitrogen gas or foam was placed in the annular gap between the tubing string and the casing.

Final comparisons are made between measured and calculated radiation doses around the holes in which the spent fuel was emplaced in the Spent Fuel Test - Climax. Neutron doses were found to be negligible compared with gamma doses. Good agreement was found between the doses predicted by Monte Carlo calculations and those measured by short-exposure thermoluminescence dosimetry. Poor agreement was found between the calculational results and doses measured by exposure of LiF optical-absorption-type dosimeters for long periods, probably because of an inability to accurately correct for fade resulting from elevated temperature exposure over several months. The maximum dose to the rock occurred at the walls of the emplacement holes, and amounted to 1.6 MGy (1.6 x 10{sup 8} rad) in granite for the emplacement period of nearly 3 years. It is recommended that dose evaluations for future high-level nuclear waste storage facilities also be performed by combining calculations and dosimetry. Passive dosimetry techniques, if used, should involve short exposures, so that laboratory calibrations can be performed with duplicate time, temperature, dose rate, and dose parameters. An attractive alternative would be to use active ionization chambers, inserted only periodically. These could be calibrated under appropriate temperature and pressure conditions, and could …

The Mirror Advanced Reactor Study (MARS) is a conceptual design of a 1200-MWe commercial tandem mirror reactor for electricity and synfuels (methanol) production. Thermal barrier end plugs of the TMX-U/MFTF-B type allow steady-state ignition of a 130-m-long central-cell DT plasma. Compact, gridless direct converters supply all the plant auxiliary power. The simple lead-lithium eutectic-cooled blanket has high neutron energy multiplication (1.36) as well as a low tritium inventory (< 8 g), and it will not melt in accidents.

In our recent experiments on the TMX-U thermal-barrier device, we achieved the end plugging of axial ion losses up to a central cell density of n/sub c/ = 6 x 10/sup 12/ cm/sup -3/. During lower density experiments, we measured the axial potential profile characteristic of a thermal barrier and found an ion-confining potential greater than 1.5 kV and a potential depression of 0.45 kV in the barrier region. The average beta of hot end plug electrons has reached 15% and of hot central cell ions has reached 6%. In addition, we heated deuterium ions in the central cell with ICRF to an average perpendicular energy of 2 keV. During strong end plugging at low density (7 x 10/sup 11/ cm/sup -3/), the axial ion confinement time tau/sub parallel/ reached 50 to 100 ms while the nonambipolar radial ion confinement time tau/sub perpendicular/ was 14 ms - independent of end plugging. Electrically floating end walls increased the radial ion confinement time by a factor of 1.8. At higher densities and lower potentials, tau/sub parallel/ was 6 to 12 ms and tau/sub perpendicular/ exceeded 100 ms.

This note presents the results for the effects of intrabeam scattering on the longitudinal and transverse beam dimensions for a beam of Au nuclei at various energies corresponding to ..gamma.. = 5 to ..gamma.. = 100, and for time periods of up to 10 hours. Intrabeam scattering is the scattering of the particles in the beam from each other through the Coulomb forces that act between each pair of particles. This causes the beam dimensions to grow both longitudinally and transversely, and results in requirements for the transverse aperture and the rf acceleration system. The beam growth also affects the collider performance, as the instantaneous luminosity will decrease with time.

Kinetics data have been determined for the catalytic hydroprocessing of the acidic fractions of a heavy distillate of a liquid derived from Powhatan No. 5 coal. A commercial, sulfided Ni-Mo/..gamma..-Al/sub 2/O/sub 3/ catalyst was used in the experiments, carried out at 350/sup 0/C and 120 atm with the coal liquid fractions dissolved in cyclohexane. The feed and hydrotreated products were analyzed by gas chromatography/mass spectrometry. The data were analyzed with group-type methods for compound classes, and results were also obtained for some individual organooxygen compounds. Catalytic hydroprocessing leads to a large increase in the number of compounds and a shift to lower boiling ranges. The data are broadly consistent with reaction networks determined with pure compounds; the most important reactions include aromatic ring hydrogenation, hydrodeoxygenation, and hydrodemethylation. Pseudo first-order rate constants for conversion of the predominant organooxygen compounds are on the order of 10/sup -4/ L/(g of catalyst.s); the reactivity decreases in the order cyclohexylphenol > dimethylhydroxyindane > tetrahydronaphthol > phenylphenol > 1-naphthol. 12 references, 15 figures, 5 tables.

The Department of Energy (DOE) commissioned a study leading to a final report (NUS-4543, Report of the Shuttle Transportation System (STS) Explosion Working Group (EWG), June 8, 1984), concerned with PuO/sub 2/ dispersal should the NASA space shuttle explode during the proposed Galileo and ISPN launches planned for 1986. At DOE's request, LLNL furnished appendices that describe hydrocode KOVEC calculations of potential damage to the Radioisotope Thermoelectric Generators, fueled by PuO/sub 2/, should certain explosion scenarios occur. These appendices are contained in this report.

A clean sample of ..gamma..p ..-->.. rho/sup -/ ..delta../sup + +/ events has been isolated in a hydrogen bubble chamber experiment having a sensitivity of 2.4 events/nb. The experiment uses a narrow band, 20 GeV photon beam produced by backscattering laser light from the Stanford Linear Accelerator's electron beam. A large lead-glass photon detector was used to measure ..pi../sup 0/'s from the rho/sup -/ ..-->.. ..pi../sup -/..pi../sup 0/ decays. We study the s and t dependence of the ..gamma..p ..-->.. rho/sup -/ ..delta../sup + +/ production process and the spin density matrix elements for the decay of the ..delta../sup + +/. These data show that this reaction is not mediated by pure one pion exchange. This result brings in doubt previous measurements of the rho ..-->.. ..pi gamma.. decay width which use a one pion exchange analysis of the ..gamma..p ..-->.. rho/sup -/ ..delta../sup + +/ reaction. 14 references.
