Geothermal R and D Project report for October 1, 1975--December 30, 1975

The Idaho National Engineering Laboratory (INEL) Geothermal Research and Development Project is conducting two major geothermal development efforts: 1) a project aimed at medium temperature (approximately 300/sup 0/F) utilization to produce electricity with supplemental direct thermal use of the energy; and 2) a low temperature (approximately 170/sup 0/F) space heating project. The first effort has progressed in the field to the successful drilling of two deep geothermal wells providing flows of the desired temperature in the Raft River Valley of south central Idaho. The second program involves the heating of government buildings and a university campus at Boise, Idaho. This report covers the period October 1, to December 30, 1975.

Uranium in alkaline rocks (open access)

Uranium in alkaline rocks

Geologic and geochemical criteria were developed for the occurrence of economic uranium deposits in alkaline igneous rocks. A literature search, a limited chemical analytical program, and visits to three prominent alkaline-rock localities (Ilimaussaq, Greenland; Pocos de Caldas, Brazil; and Powderhorn, Colorado) were made to establish criteria to determine if a site had some uranium resource potential. From the literature, four alkaline-intrusive occurrences of differing character were identified as type-localities for uranium mineralization, and the important aspects of these localities were described. These characteristics were used to categorize and evaluate U.S. occurrences. The literature search disclosed 69 U.S. sites, encompassing nepheline syenite, alkaline granite, and carbonatite. It was possible to compare two-thirds of these sites to the type localities. A ranking system identified ten of the sites as most likely to have uranium resource potential.

Some effects of magnetic walls on the transverse motion of an intense beam of charged particles (open access)

Some effects of magnetic walls on the transverse motion of an intense beam of charged particles

The focusing properties of a magnetic medium surrounding a beam of relativistic particles were examined. The magnitude of the magnetic forces generated by the wall is proportional to the beam current. For a current of the order of 10 kA, significant magnetic field gradients are obtained. It was concluded that the series of structures studied is not satisfactory for providing focusing of an intense beam of particles. However, the characteristics of the transverse forces suggest a method of constructing a passive, current-dependent, deflector for an intense beam.

Effects of substrate temperature on silicon nitride cracking of beam lead devices during thermocompression wobble bonding (open access)

Effects of substrate temperature on silicon nitride cracking of beam lead devices during thermocompression wobble bonding

Recent failures in several completed Sandia Laboratories' electronic systems have traced to specific format 25 beam lead transistors and diodes. More extensive failure analysis on the devices showed them to exceed their respective specifications in electrical leakage. All of the failed devices were observed to have one thing in common: cracked silicon nitride over the beams. These observations triggered several investigations to determine if cracked silicon nitride causes electrical failures, where (processing, assembly, etc.) nitride cracking occurs, and when nitride cracking can be reduced or eliminated. The effects of changes in substrate temperature and force upon nitride cracking during bonding are described. Devices were bonded at 150, 200, and 250/sup 0/C, and at 250 and 525 gms of force, and the amount of nitride damage in the bonding operation was determined. Neither parameter had large effects in cracking. The pulled strength and failure modes were recorded. The results showed that approximately 22 percent of the devices developed silicon nitride cracks over the beams. Total production handling and processing result in 80 to 90 percent of the devices having cracked nitride. Although the sample size is small (63 devices), it does not appear that the cracking is dependent on the substrate …

Status of beta- and gamma-decay and spontaneous-fission data from transactinium isotopes

Several categories of ..beta..- and ..gamma..-related decay data for the transactinium isotopes are assessed in the light of their potential use in applied areas. The status as of August, 1975, of these data is summarized for 142 transactinium nuclides with 228 less than or equal to A less than or equal to 257 by the listing of experimental values and errors where known. Several useful compilations of transactinium-isotope decay data are discussed. Recent developments related to the yields and energy distributions of prompt and delayed neutrons from spontaneous fission are briefly treated. Comments and observations about the interrelation of the important nuclear-data activities of measurement, compilation and evaluation and needs assessment are given. The applications-oriented file of decay data prepared at our laboratory for ENDF/B is discussed. Finally, a summary by G. Rudstam of the status of the OSIRIS work on delayed-neutron energy spectra of individual precursors is included.

Final report on investigation of stability of organic materials in salt cake (open access)

Final report on investigation of stability of organic materials in salt cake

On the basis of this work the following conclusions, which all contribute to confidence that salt cake is stable against exothermic reactions, were reached. Organics added to the waste tanks were not nitrated at the time of addition and cannot have been subsequently transformed to detonatable nitrated organics. Whatever organic has found its way into the tanks has been and will be essentially unaffected by radiation. Mixtures of the types of organics which could have been added to the waste tanks with either simulated salt cake or pure sodium nitrate are not detonatable. The maximum amount of organic which could have been added to the waste tanks is less than 0.9 weight percent of the salt cake, a concentration far below the concentration required to support combustion. The many years during which the liquid high-level waste was boiling, and the subsequent evaporation-crystallization processing, have allowed many of the more volatile organics to be distilled off, further reducing the maximum expected concentration of organics. The occurrence of an explosive exothermic reaction of an organic in the waste tanks would require concentration and mixing by an unknown and uncontrolled means. The mixture would then have to remain in its concentrated state long …

TRUEX hot demonstration (open access)

TRUEX hot demonstration

In FY 1987, a program was initiated to demonstrate technology for recovering transuranic (TRU) elements from defense wastes. This hot demonstration was to be carried out with solution from the dissolution of irradiated fuels. This recovery would be accomplished with both PUREX and TRUEX solvent extraction processes. Work planned for this program included preparation of a shielded-cell facility for the receipt and storage of spent fuel from commercial power reactors, dissolution of this fuel, operation of a PUREX process to produce specific feeds for the TRUEX process, operation of a TRUEX process to remove residual actinide elements from PUREX process raffinates, and processing and disposal of waste and product streams. This report documents the work completed in planning and starting up this program. It is meant to serve as a guide for anyone planning similar demonstrations of TRUEX or other solvent extraction processing in a shielded-cell facility.

Study of the effects of radiation of nucleic acids and related compounds. Progress report, August 15, 1975--August 14, 1976

Ionizing radiation produces genetic effects in biological systems. Since genetic effects are usually the result of modifications of DNA or sometimes of RNA, interest is being centered on the chemical and physical nature of radiation-induced lesions to nucleic acids and their components. These investigations have revealed the enormous complexity of chemical events and the possible degradation of nucleic acids by strand breakage. Therefore, work in the ionization radiation of nucleic acids has proceeded along a dual course. On the one hand, molecular changes have been characterized for a number of primary radiation products. On the other hand, strand breakage has been investigated intensively as a direct primary event. Both of these aspects were emphasized in our research last year. We succeeded in improving the synthesis of 5-hydroxy-methyl thymine (..cap alpha..-TOOH). ..cap alpha..-TOOH was found to be much more effective than cis-5,6-dihydro-6-hydroperoxy-5-hydroxy thymine (6-TOOH) in the inactivation of transforming DNA of H. influenzae cells although ..cap alpha..-TOOH is much less reactive chemically than 6-TOOH. 6-TOOH causes inactivation and acts as an inhibitor of DNA synthesis in mammalian cells. In addition, evidence may indicate that 6-TOOH does not induce strand breaks directly in DNA although we showed that 6-TOOH is a clastogenic …

Simple method to unfold NE 213 and stilbene neutron spectral data

A very simple method is proposed wherein recoil proton scintillation data are reduced using the derivative unfolding technique. The approximations described require minimal calculation or storage and may be readily implemented on a mini computer. A digital filter is incorporated which yields a smoothed approximation to the slope of the pulse-height distribution, with error estimates. In order to accurately represent the scintillator light output without introducing discontinuities in the unfolded spectrum, the light output data are fitted using B-splines whose first and second derivatives are continuous.

Effects of fueling profiles on plasma transport (open access)

Effects of fueling profiles on plasma transport

A one-dimensional (1-D), multifluid transport model is used to investigate the effects of particle fueling profiles on plasma transport in an ignition-sized tokamak (TNS). Normal diffusive properties of plasmas will likely maintain the density at the center of the discharge even if no active fueling is provided there. This significantly relaxes the requirements for fuel penetration. Not only is lower fuel penetration easier to achieve, but it may have the advantage of reducing or eliminating density gradient-driven trapped particle microinstabilities. Simulation of discrete pellet fueling indicates that relatively low velocity (approximately 10/sup 3/ m/sec) pellets may be sufficient to fuel a TNS-sized device (approximately 1.25-m minor radius), to produce a relatively broad, cool edge region of plasma which should reduce the potential for sputtering, and also to reduce the likelihood of trapped particle mode dominated transport. Low penetrating pellets containing up to 10 to 20 percent of the total plasma ions can produce fluctuations in density and temperature at the plasma edge, but the pressure profile and fusion alpha production remain almost constant.
