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
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
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.

Pacific Northwest Laboratory quarterly report to ERDA Nuclear Research and Applications Division, January--March 1976. [Use of /sup 90/SrF/sub 2/ and /sup 137/CsCl WESF capsules as heat sources]
Progress in the strontium heat source and beneficial isotopes utilization programs is discussed. The couples required for the long-term tests compatibility were fabricated and the tests are under way. The 1000-hr tests were completed, and examination of the test couples has been started. Compatibility testing of two full-scale WESF /sup 90/SrF/sub 2/ capsules at 800/sup 0/C has started. Additional short-term compatibility testing of 25 potential containment materials are also under way. The 5000-hr aging tests of Hastelloy C-4 were completed and the specimens are being examined. Conceptual flowsheets were drawn up for recovery of various combinations of radioisotopes from stored high level wastes, and rough cost estimates were made. Additional calculations of /sup 137/CsCl capsule irradiation efficiency are reported. Conclusions of a study of the beneficial utilization of WESF /sup 90/SrF/sub 2/ capsules are presented.

CALOR: a Monte Carlo program package for the design and analysis of calorimeter systems. [In FORTRAN IV]
CALOR is a Monte Carlo program package, written in FORTRAN IV, that is designed to assist experimentalists in evaluating and analyzing different types of calorimeter systems that are used in many high-energy physics experiments to determine the energy and direction of incident hadrons, leptons, and photons. This code package is intended to be used with the code package HETC, which supplies needed information on the transport of hadrons and on the spatial location of the electromagnetic source energy. Input and output for a sample problem are presented. 3 figures, 1 table.

Modification of a hardwired numerical control to include switchable Inch/Metric capability. [Digital logic of Hughes N/C Model 2000 Control on EE Monarch lathe]
A unique and relatively simple method is described for modifying a 1965-vintage hardwired numerical control (N/C) for a machine tool so that it can operate in the SI (Metric) as well as the Inch mode. The modification procedure will be valuable during the transition from Inch to SI measurements, as it allows a numerically-controlled machine tool originally designed to operate only in the Inch mode to be ''recycled'' for SI use. The system digital logic of a Hughes N/C Model 2000 Control on an EE Monarch lathe was modified by changing the modulus of the Command Phase and Reference counters so that the control system has a SI modulus as well as an Inch modulus. The modified system thus allows selection of either the SI operating mode or the Inch mode by a front panel switch.

Summary report of the compressive creep properties of irradiated and unirradiated molybdenum. [Fast neutrons]
Compressive creep tests were performed on molybenum samples exposed to four different pre-test conditions: (1) annealed; (2) annealed and neutron irradiated at 480/sup 0/C to a fluence of 5 x 10/sup 19/ n cm/sup -2/ (E > 1 MeV); (3) stress-relieved; and (4) stress-relieved and neutron irradiated at reactor ambient temperature to a fluence of 1 x 10/sup 19/ n cm/sup -2/ (E > 1 MeV). The tests were performed in the temperature range of 600 to 900/sup 0/C with an initial applied stress of 176.5 MPa. Both pre- and post-test specimens were examined using electron microscopy and the relationship between substructure and mechanical properties is discussed. Possible controlling mechanisms of deformation are proposed and activation energies for creep are determined.

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 …

Solar proton fluxes since 1956
The fluxes of protons emitted during solar flares since 1956 were evaluated. The depth-versus-activity profiles of /sup 56/Co in several lunar rocks are consistent with the solar-proton fluxes detected by experiments on several satellites. Only about 20% of the solar-proton-induced activities of /sup 22/Na and /sup 55/Fe in lunar rocks from early Apollo missions were produced by protons emitted from the sun during solar cycle 20 (1965--1975). The depth-versus-activity data for these radionuclides in several lunar rocks were used to determine the fluxes of protons during solar cycle 19 (1954--1964). The average proton fluxes for cycle 19 are about five times those for both the last million years and for cycle 20. These solar-proton flux variations correlate with changes in sunspot activity.

Maintenance approaches and practices in selected foreign nuclear power programs and other US industries: Review and lessons learned
The Commission published a Notice of Proposed Rule-making on Maintenance of Nuclear Power Plants on November 28, 1988, spelling out NRC's expectations in maintenance. In preparing the proposed rule, the NRC reviewed maintenance practices in other countries and considered maintenance approaches in other industries in this country. As a result of the review of maintenance practices, it was concluded that certain practices in the following areas have been found to contribute significantly to effective maintenance: (1) systems approach; (2) effectiveness monitoring; (3) technician qualifications and motivation; and (4) maintenance organization. 87 refs., 26 figs., 2 tabs.

How to estimate the solubility of an insoluble compound: 1,3,5-triamino-2,4,6-trinitrobenzene (TATB)
A simple method for estimating the solubility of TATB in various solvents is presented. We consider it unlikely that a solvent will be found in which TATB is more soluble than 0.1 percent (w/v). Exceptions are the so-called superacids in which the solubility of TATB exceeds 20 percent (w/v).

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.
