Effect of fuel recycling on radioactivity and thermal power of high-level wastes

Description: The radioactivity and thermal power of high-level and plutonium-bearing wastes from the nuclear fuel cycle have been calculated for the years 1975 to 2005 using the rate of generation of such wastes projected for the Generic Environmental Statement on Mixed Oxide Fuel (NUREG-0002). Three modes of fuel recycle are considered: (1) no recycle, (2) uranium recycle, and (3) prompt uranium and plutonium recycle. These cases are compared with a respect to radioactivity and thermal power of the generat… more

Development of passive electronic components for instrumentation of improved geothermal logging tools and components. Annual progress report

Description: Short term objectives for well-logging instrumentation are circuits which can operate at temperatures in the range 275/sup 0/C to 350/sup 0/C; the medium term goal is operation up to 500/sup 0/C, and the long term goal is to achieve operation at 1000/sup 0/C. It is apparent that useful electronic circuits will require the combination of both passive components and active devices. In order to meet the compatibility requirements, the basic technology which has been selected in this project is the… more

Mechanical properties of LX-10-1. Process Development Endeavor No. 105

Description: Two Holston lots of LX-10-1 were evaluated for mechanical properties. The average 21/sup 0/C tensile failure stress-strain values for Lot 711-1 and 711-2 were 2.32 MPa at 0.15% and 2.07 MPa at 0.18%, respectively. The failure stress range for both lots was approximately 0.4 MPa at 74 C to 5.6 MPa at -37C. Several additional pressing cycles were required to obtain a density of 1.865 Mg/m/sup 3/ for Lot 711-1 material. The additional cycles appear to have increased the tensile failure stress of L… more

Analysis of homogeneous U233 and U235 critical assemblies with ENDF/B-IV data (AWBA development program)

Description: Thirty-two U233 and U235 homogeneous aqueous critical experiments were analyzed with ENDF/B-IV data. Calculated eigenvalues for both fuel types increased by nearly 2 percent over the range of hydrogen/uranium atomic ratio covered (from 2106 to 27.1). This is attributed mostly to an underprediction of fast leakage, with some contribution from the fission and capture resonance integrals of ENDF/B-IV U235. Eigenvalue sensitivities to several nuclear data changes were examined. Values of the therma… more

Sampling and characterization of sodium-water reaction products

Description: Sodium-water reaction products (SWRP) which had accumulated in the bottom of the reaction products tank (RPT) of the Large Leak Test Rig (LLTR) were sampled and characterized. Analysis showed that the SWRP consisted of NaOH, Na/sub 2/O, NaH, and Na, as expected, in varying proportions. The unreacted sodium in the samples examined ranged from 32 to 60% by weight. The SWRP reacts (dissolves) rapidly and completely with ethanol, and somewhat less rapidly and completely with Dowanol PM. A magnetic,… more

Effect of generalized wind characteristics on annual power estimates from wind turbine generators

Description: A technique is presented for estimating the average power output of a wind turbine using, as the wind characteristic input, only the mean annual wind magnitude. Hourly wind speeds are assumed to have a Rayleigh frequency distribution which requires a single parameter input (e.g., the mean value, variance or higher moment values). Based upon a general shape, for the wind speed versus machine output, a generic set of curves is developed to estimate the average power output of wind turbines. Also,… more

Low-pressure approach to the formation and study of exciplex systems. [For CDC 7600]

Description: Studies on the formation and properties of new materials for high-energy, gas-phase lasers are described. Attention is directed mainly to systems having bound excited states but unbound ground states. An important class of such excimer/exciplex systems has a van der Waals dimer/oligomer as its ground state. This research attempts to probe the relative rates of electron pumping of excited-state manifolds and the preferentially pumped vibronic states within each manifold. Reactive quenching of em… more
