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

Choice of working fluid and operating conditions for energy conversion with geothermal heat sources

Description: A study of electric power generating cycles which can be used in conjunction with a low-temperature geothermal energy (sensible heat) source is presented. Investigators at Los Alamos Scientific Laboratory have proposed a steam/isobutane dual cycle capable of generating 50.7 Mw of electric power. This cycle is optimized using regenerative feed water heating to yield a power output of 52.1 Mw or an improvement of 2.8%. Other power cycle designs and working fluids are investigated. Working fluids … more

Baseline Gas Turbine Development Program Fourth Quarterly Progress Report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1976 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Reasonably firm delivery schedules were arranged for all of the critical Task 1 engine parts. However, the program will likely have to continu… 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

Review of Brookhaven National Laboratory superconducting power transmission program

Description: ABS>Research is being conducted at Brookhaven National Laboratory to develop a superconducting ac cable system leading to the construction of a 1/2 mile model cable of 200 MVA capacity at Brookhaven and a cable of larger (>2000 MVA) capacity for test at a utility testing site. It is a coaxial cable of flexible design using Nb/sub 3/Sn superconductor, and a tape wound dielectric, helium impregnated, of a material yet to be determined. The research development is reported on the dielectric materi… 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

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

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. Complex expansion parameters are considered so that numerical results for physical problems involving energy dissipation as well as energy flow can be obtained. Sample numerical results are presented for the eigenvalues, radial eigenfunctions, and angle eigenfunctions. Applications of these results are discussed. (auth)

New transient surface-current sensor and recorder

Description: It was demonstrated that a transient surface-current pulse can be sensed and recorded by a graded-Hc film, a magnetic film with the coercive force Hc varying along the length of the film. Information on the magnitude of the current can be obtained by comparing the domain-wall location with the distribution of Hc value along the film. The transient characteristic of the current pulse can be deduced from the V-shaped configuration of the domain wall. (auth)

Can-rolling of beryllium ingots

Description: Aspects of hot-rolling cast-beryllium billets canned in 304 stainless steel are examined. Emphasis is placed on the development of the proper rolling schedule to completely convert the columnar cast structure to a uniform equiaxed one. Also emphasized are curling difficulties found in rolling this two-metal composite. The curling is found to depend chiefly on friction between ths billet and work rolls. Lubrication and roll surface finish are found to be the key variables which in turn control f… more

Symmetry of laser driven implosions

Description: The achievement of significant nuclear energy yields from laserheated pellets of thermonuclear fuel requires that the fuel be compressed to at least several orders of magnitude above initial density. Such compressions can be attained by spherical implosions, but because of the large compression ratios required, these implosions must be highly symmetrical. Calculations of the behavior of imploding spheres and shells by a spherical harmonic perturbation method, and by two-dimensional hydrodynamic… more
