Homogenization of arc-melted uranium-6 weight percent niobium alloy ingots

Description: Microsegregation and macrosegregation in uranium-6 niobium arc-melted ingots were characterized by electron microprobe analysis. Homogenization studies determined that microsegregation can be eliminated by heat treating the alloy for six hours at 1100/sup 0/C. Extensive homogenization did not eliminate macrosegregation (banding) from the as-cast alloy, but a mathematical model describing banding and coring indicated that banding could possibly be eliminated by working prior to homogenization.

Evaluation of ultrafiltration membranes for treating low-level radioactive contaminated liquid waste

Description: A series of experiments were performed on Waste Disposal Facility (WD) influent using Romicon hollow fiber ultrafiltration modules with molecular weight cutoffs ranging from 2000 to 80,000. The rejection of conductivity was low in most cases. The rejection of radioactivity ranged from 90 to 98%, depending on the membrane type and on the feed concentration. Typical product activity ranged from 7 to 100 dis/min/ml of alpha radiation. Experiments were also performed on alpha-contaminated laundry w… more

Apparatus for simultaneously measuring electrical conductivity and oxygen fugacity

Description: Electrical conductivity studies of silicates are useful in determining temperature vs depth in the earth. Realistic laboratory measurements of conduction mechanisms require that exact determinations of oxygen fugacity (fo{sub 2}) be made in the experimental environment. An apparatus is described that monitors system fo{sub 2} with a calcia-doped zirconia-oxygen cell while measuring electrical conductivity of iron-bearing silicates at high temperature (greater than 1000 K). The fo{sub 2} calcula… more

System for vacuum pouring of epoxy tensile and impact specimens with a study of the behavior of these specimens at 77 K and 293 K

Description: The purpose of the investigation was to establish a suitable technique for vacuum pouring of epoxy test specimens and to study the behavior of these specimens at 77 K and 293 K. A series of tensile and impact tests was conducted using specimens made from the following resins: Epon 828, Epon 871, and Epon curing agent Z. These materials are of general interest to designers of magnets for cryogenic service. Tests of the specimens were carried out at 77 K and 293 K. The 77 K data indicate that ten… more

Stress analysis of loft (ECC) system; left side

Description: An analysis has been performed by the Applied Mechanics Branch on a new Left Side configuration of the LOFT Emergency Core Coolant (ECC) System. This system has been geometrically modified from that analyzed in a previous report, LTR 113-40. LOCE and Safe Shutdown Earthquake (SSE) were the only loading conditions considered capable of producing high stresses. Review of the analyses indicates that the new configuration passes the requirements of the ASME Code for Class 1 and 2 piping.

Determination of bulk diffusion lengths for angle-lapped semiconductor material via the scanning electron microscope: a theoretical analysis

Description: A standard procedure for the determintion of the minority carrier diffusion length by means of a scanning electron microscope (SEM) consists in scanning across an angle-lapped surface of a P--N junction and measuring the resultant short circuit current I/sub sc/ as a function of beam position. A detailed analysis of the I/sub sc/ originating from this configuration is presented. It is found that, for a point source excitation, the I/sub sc/ depends very simply on x, the variable distance betwee… more

High-temperature explosive development for geothermal well stimulation. Final report

Description: A two-component, temperature-resistant liquid explosive called HITEX has been developed which is capable of withstanding 561/sup 0/K (550/sup 0/F) for 24 hours in a geothermal environment. The explosive is intended for the stimulation of nonproducing or marginally producing geothermal (hot dry rock, vapor-dominated or hydrothermal) reservoirs by fracturing the strata in the vicinity of a borehole. The explosive is inherently safe because it is mixed below ground downhole from two nondetonable l… more

Data accumulation on the methane potential of the coal beds of Colorado. Final report

Description: A two-year project was conducted to gather data that would assist in the evaluation of the methane potential of the coal beds of Colorado. It was found that a number of closed underground coal mines in the State had reported gassy conditions or had experienced fires and explosions of varied intensity and frequency. The majority of such occurrences have been in those areas characterized by coals of relatively low (i.e., below 31%) volatile matter (VM) content. The south half of the Raton Mesa co… more
