Critical Concentration Of Uranium Solution

Description: The experiments with U(37)O{sub 2}F{sub 2} aqueous solution followed the series of experiments with {sup 233}UO{sub 2}(NO{sub 3}){sub 2} and U(93)O{sub 2}(NO{sub 3}){sub 2} solutions in the 69.2-cm-diam sphere. The critical concentrations of {sup 233}U and {sup 235}U were used to evaluate the ratio of {ovr {eta}{sigma}{sub a}}(233)/{ovr {eta}{sigma}{sub a}}(235) some years ago when the accepted value of {ovr {eta}}(233) was questioned. The purpose of the experiment reported here was to measure … more

Faceting of high angle grain boundaries in the coincidence lattice

Description: Faceting of high angle grain boundaries in SIGMA = 3 and SIGMA = 5 coincidence lattices of the fcc structure was studied using thinfilm bicrystal specimens of controlled geometry. A number of relatively high index boundaries in the coincidence lattices (containing relatively low planar densities of coincidence sites) was found to break up into low energy facets corresponding to low index planes of the coincidence lattices (containing high densities of coincidence lattice sites). These results a… more

SWAN: a code for the analysis and optimization of fusion reactor nucleonic characteristics

Description: This report is intended as a User's Manual for SWAN''--- a code written for perturbation theory analysis and optimization of the nucleonic characteristics of fusion reactor blankets. SWAN is also applicable to any problem described by the inhomogeneous linear transport equation, e.g., radiation shield problems. The optimization method is based on variational techniques. The variables of the optimization are material densities, with no restriction on their number. One joint restra… more

Method of inspecting dielectric materials at microwave frequencies

Description: A successful method of screening high-dielectric-constant, nonmagnetic, high-loss-factor materials at microwave frequencies was developed to provide material control by incoming inspection. This is accomplished by measuring the S parameters of the material---reliance on the manufacturer's permittivity data and x-ray examination for voids and inclusions is no longer necessary. Use of an automatic network analyzer makes 100% inspection economically feasible. (auth)

Multiparticle detector for ISABELLE

Description: The proposed multiparticle spectrometer is designed to study particles produced at small angles (0.5 < theta < 20 mr). It is assumed to be part of a larger set-up, where the larger angles are covered by other spectrometers, or at least a 4 pi detector, such as described by Arnold et al. (CRISP 72-65). The general layout consists of 4 magnets in a symmetrical arrangement. A set of proportional chambers downstream from the first set of magnets can measure both angle and momentum. Using a second p… more

Fast reactor analytical shielding progress report for July and August 1973. 189a No. 10318, activity No. HN 04 01 01 1

Description: Analytical shielding work performed for the fast reactor program during the months of July and August included calculations for both the FFTF and the Demo plant, computer code development, analyses of TSF experiments, and a cross- section sensitivity study of a TSF experiment. Most of the FFTF studies were aimed at determining the effect of various design changes on the dose rates at the maintenance deck during reactor operation, in particular, the effects of penetrations through the radial cav… more

TART calculations using the new 2021 energy group cross section library compared with B. Czirr&#x27;s resonance self-shielding experiments

Description: Results from calculations using a 2021-energy-group cross section library with sufficient energy definition in the lower energy range to resolve the known resorances in /sup 239/Pu and /sup 235/U are compared with flat-plate resorance self-shielding experimental data. The results are somewhat ambiguous. The lower energy ranges appear to agree better with experimental data for small areal densities, but disagree more as the areal density increases.

Long-term stability of Alnico 5 and 8 magnets at 700 to 1200$sup 0$F

Description: Tests performed to determine the long-term stability of Alnico 5 and 8 magnets for use in permanent magnet in-core sodium flowmeters are described. The results of this experiment showed that two processes combine to affect magnetic stability of these magnets at temperatures above 700 deg F: loss of field strength with time, the rate of loss increasing with temperature, and partial recovery of the loss caused by a high-temperature stabilization. The conclusion is that for a given temperature the… more

In situ permeability measurements for the event in U1-C

Description: Test apparatus was designed for the measurement of the in situ permeability in the vicinity of the 1100-ft UI-C shaft at NTS. A very reasonable approximation to a one-dimensional flow geometry was obtined. Measurement of gas injection flow rates and pressures allowed the determination of the effective permeability of the medium around the Ul-C shaft to be from 1 to 10 darcys with the major exceptions at depths of less than 200 ft where the permeability was greater than 40 darcys. However, perme… more

Project Rio Blanco spall measurements data report

Description: A major instrumentation program was undertaken for the Rio Blanco experiment using accelerometers and velocity gages buried at various depths below the ground surface and at various horizontal ranges from the emplacement well. The objective was to physically measure the depth and aerial extent of spall (tensile failure of the earth material). Data from each of the instrument stations is given, along with the appropriate integrated data for particle velocity and displacement or just displacement… more

High-pressure mechanical properties of an Area 12, Nevada Test Site tuff

Description: The mechanical properties of tuff from instrument hole UG3, tunnel U12e.06 at the Nevada Test Site have been investigated to 1400 MPa, The shear strength increases from about 5 MHa unconfined to 12 MPa at 300 MPa mean pressure. A brittle-ductile transition was indicated at about 250 MPa. In uniaxial strain, the sample loads to the vicinity of the failure envelope and then is parallel to that envelope up to the highest stresses, 420 MPa. Hydrostatic pressure of 1400 MPa produces about 9% volume … more

Strain seismometer data from the ALMENDRO event at NTS

Description: The ALMENDRO Event was conducted on Pahute Mesa at NTS, and was announced as an intermediate yield event (200 to 1000 kt). Strainmeter records were obtalned at three locations in Yucca Flat. One recording site was a triaxial station; the other two were two component stations. The station parameters and pertinent data relating to ALMENDRO are summarized in tabular form. (TFD)

Feasibility evaluation and R and D program plan for transuranic partitioning of high-level fuel reprocessing waste

Description: An approach to managing high-level radioactive waste is to separate it into fractions of different half-lives. Existing separations technologies were reviewed and their potential for this application assessed, process concepts expected to be capable of these separations were defined, areas where R&D to develop and design an effective process is required were identified, and an R&D plan for selection and development of a partitioning process was prepared. A wide spectrum of technologies was init… more

241-T-106 tank leak investigation

Description: On June S, 1973, the 241-T-106 underground liquid waste storage tank, located on the U. S. Atomic Energy Commission's Hanford reservation, was confirmed as leaking. It was predicted that the leaked waste would be retained by the dry sediments well above the water table. A study was instigated to confirm this prediction. Results show the deepest penetration observed was 27 meters below the ground surface or 35 meters above the water table (approximately S7 and 116 feet, respectively). Based on t… more
