Irradiation of three T-111 clad uranium nitride fuel pins for 8070 hours at 990/sup 0/C (1815/sup 0/F)

Description: The design and successful operation of three tantalum alloy (Ta-8W-2Hf) clad uranium mononitride (UN) fuel pins irradiated for 8070 h at 990/sup 0/C (1815/sup 0/F) is described. Two pin diameters having measured burnups of 0.47 and 0.90 uranium atom percent were tested. No clad failures or swelling was detected; however, postirradiation clad samples tested failed with 1 percent strain. The fuel density decrease was 2 percent, and the fission gas release was less than 0.05 percent. Isotropic fue… more

Parameter studies on the effect of pulse shape on the dynamic plastic deformation of a hexagon

Description: Results of a parameter study on the dynamic plastic response of a hexagonal subassembly duct subjected to an internal pressure pulse of arbitrary shape are presented. Plastic distortion of the cross section and large-deformation geometric effects that result in redistribution of the internal forces between bending and membrane stresses in the hexagon wall are included in the analytical model. Correlation procedures are established for relating permanent plastic deformation to simple properties … more

Versatile rock-melting system for the formation of small-diameter horizontal glass-lined holes

Description: Rock-melting penetrators with diameters ranging from 50 mm (2 in.) to 76 mm (3 in.) have reached a stage of development at the Los Alamos Scientific Laboratory (LASL) which suggests that these devices are ready for practical application. Prototype refractory metal penetrators have formed glass-cased vertical holes of 26 m (82 ft) in a single run, and horizontal holes with diameters up to 127 mm (5 in.) are expected in the near future. These small horizontal holes can be used for underground uti… more

Shallow Solar Pond scheme. Performance assessment of a model system

Description: The division of energy among the various competing processes is discussed in the sequence from the collection of the solar flux, to the production of electrical power at a busbar output'' for the Shallow Solar Pond scheme. The solar collector utilizes shallow flowing water to transfer thermal energy to a hot water reservoir (at approximates 95 deg C). Several layers of plastic sheet cover the collection area to suppress heat losses. A Rankine Cycle thermodynamic system converts part o… more

Prospects for Y* experiments

Description: From meeting of the division of particles and fields; Berkeley, California, USA (13 Aug 1973). It is noted that a major problem with Y* studies stems from difficulty in constructing low-momentum K/sup -/ beams of high intensity which could be employed in formation experiments using electronic means to accumulate high statistics. The status of bubble-chamber and electronic experiments is discussed. Somedata are given on the established and conjectured Y* states. (LBS)

Electromagnetic pulse source characteristics experiment on an underground nuclear event

Description: From EMP technical meeting; Kirtland AFB, New Mexico, USA (25 Sep 1973). Under sponsorship of the Advanced Research Projects Agency, the Lawrence Livermore Laboratory conducted an EMP experiment in conjunction with an underground nuclear event. The purpose of the overall study of which this experiment was a part was to document the characteristics of EMP signals generated by various underground nuclear events to provide checks for theoretical models under development. A major goal was to establ… more

Mechanical Properties of Blair Dolomite

Description: Pressure-volume, uniaxial stress loading to failure, uniaxial strain, and acoustic velocity determinations were made on Blair dolomite at confining pressures ranging to 3.5 GPa (Pa = Paschals where 10/sup 5/ Pa = 1 bar or 0.1 GPa = 1 kbar). The bulk modulus K, rapidly rises from an initial 10.4 GPa (at atmospheric pressure) to 102.0 GPa at 1 GPa pressure. At higher pressures, K remains essentially constant (110 GPa). The maximum volume change on loading is 3.9% at 3.5 GPa; the unloading closely… more

Method for increased accuracy in Eulerian fluid dynamics calculations

Description: A method for increased accuracy in Eulerian fluid dynamics calculations is described. The essence of the method is local cancellation of low-order, diffusional truncation errors. These errors are the source of nonlinear numerical instabilities. The methodology is described in general and specific application is made to the transient, two-dimensional flow equations for chemically reacting mixtures. Two example problems are solved to illustrate the method. For comparison, the same problems are so… more

Determination of trace quantities of thorium in uranyl nitrate by x-ray emission spectrometry

Description: Trace quantities of thorium in uranium were separated by precipitating thorium fluoride from a 1.0M HF-1.0M NH/sub 4/F matrix using yttrium as an internal standard and lanthanum as a carrier. The thorium precipitate was collected on a filter and analyzed by x-ray emission spectrometry. The method has a detection limit of about 15 mu g thorium per gram of uranium. The relative accuracy and precision at the 120- mu g thorium level was 95.5 plus or minus 1.5%. Studies on the rate of precipitation,… more

MOSFET detector evaluation

Description: From nuclear science symposium; San Francisco, California, USA (14 Nov 1973). Metal-oxide-semiconductor devices have been evaluated as lowenergy (250 eV to 50 keV) x-ray dosimeters. They can be used to measure dosages as low as 1 rad (SiO/sub 2/) to as high as 10/sup 5/ rad (SiO/sub 2/). Their small size and basic simplicity make it possible to form arrays of dosimeters for x-ray imaging. When compared to thermoluminescent dosimeters (TLD's), photographic film, and thermopiles, MOSFET dosimeter… more

Research and development activities, waste fixation program. Quarterly progress report, July--September 1973

Description: The aim of the melt development program is to produce meltformed ceramic products that have the optimum combination of physical properties for the fixation of radioactive wastes. Depending on thermal treatment many of the ceramics can be in either a glassy or a microcrystalline form. Laboratory and nonradioactive pilot plant tests are being conducted to evaluate both forms. Both PW-4b and PW-6 waste compositions were successfully solidified into borosilicate glass in the development spray solid… more

Solutions of the scalar Helmholtz equation in the elliptic cylinder coordinate system

Description: A method for determining the eigenvalues for the scalar Helmholtz equation in the elliptic cylinder coordinate system is described.
