Design of grazing incidence monochromators involving unconventional gratings

Description: We review the basic aspects of second order focusing of straight and parallel grooved varied line space gratings in both converging and collimated light in a more explicit and detailed manner that we have found in the literature. The effects of the VLS correction to the location of the focal curve for grazing incidence geometries are found to be very significant. 6 refs., 6 figs.

Alternative waste forms for immobilization of transuranic wastes

Description: Several alternative waste forms are being considered for the immobilization of consolidated trnsuranic (TRU) wastes. General characteristics and applicability of these waste forms to TRU wastes are reviewed. Specific attention is given to recent experimental results on sintered ceramic TRU waste forms including bulk properties, impact resistance, leachability, and volatility.

Wastes from selected activities in two light-water reactor fuel cycles

Description: This report presents projected volumes and radioactivities of wastes from the production of electrical energy using light-water reactors (LWR). The projections are based upon data developed for a recent environmental impact statement in which the transuranic wastes (i.e., those wastes containing certain long-lived alpha emitters at concentrations of at least 370 becquerels, or 10 nCi, per gram of waste) from fuel cycle activities were characterized. In addition, since the WG.7 assumed that all … more

Adsorption of chromate/organic-acid mixtures in aquifer materials

Description: The overall objective of this project is to develop a fuller understanding of the interactions of mixtures of anionic co-contaminants with oxide-mineral surfaces. Our specific focus is on the competitive interactions of chromate and oxalic acid on ferric oxyhydroxide and on natural aquifer materials. Chromate and oxalate are of practical interest as widespread contaminants at many DOE facilities. However, these anions also are excellent model adsorbates for elucidating fundamental aspects of io… more

The differential method for grating efficiencies implemented in mathematica

Description: In order to facilitate the accurate calculation of diffraction grating efficiencies in the soft x-ray region, we have implemented the differential method of Neviere and Vincent in Mathematica [1]. This simplifies the programming to maximize the transparency of the theory for the user. We alleviate some of the overhead burden of the Mathematica program by coding the time-consuming numerical integration in C subprograms. We recall the differential method directly from Maxwell`s equations. The pse… more

Derivation of aberration coefficients for single-element plane-symmetric reflecting systems using Mathematica{trademark}

Description: The definition of the generalized optical path function for a grating or mirror with a single plane of symmetry is reviewed. The generalized optical path function is then expanded in a series of wavefront aberration terms using only a few lines of code in the Mathematica{trademark} scientific programming environment. The use of the algebraic capabilities of the Mathematica{trademark} environment allows straightforward calculation of aberration coefficients that would normally require considerab… more

Description: 40 CFR Part 61 (Subpart H of the NESHAP) requires DOE facilities to use approved sampling procedures, computer models, or other approved procedures when calculating Effective Dose Equivalent (EDE) values to members of the public. Currently version 1.0 of the approved computer model CAP88-PC is used to calculate EDE values. The DOE has upgraded the CAP88-PC software to version 2.0. This version provides simplified data entry, better printing characteristics, the use of a mouse, and other feature… more

Trace elements in coal: Modes of occurrence analysis. Technical progress report, October 5, 1995--March 31, 1996

Description: CQ, Inc. proposed to quantify the relationship between the modes of occurrence of twelve trace hazardous air pollutants (HAP`s) elements in coal and the degree that each element can be removed by existing and advanced physical and chemical coal cleaning processes. They also proposed to investigate new chemical and biological trace element removal processes, and estimate the concentration and stability of trace elements in coal preparation plant tailings. The ultimate goal of this effort is to p… more

Hydrothermal growth kinetics of Np(IV) oxide

Description: Toulouse, France All previous knowledge leading to this estimate is of NpO2(c) is indirect, based on thermodynamic cycles. The phase itself has heretofore not been observed as a precipitate from aqueous solution. Recent attempts (e.g., Nitsche et al., 1993; Efurd et al., 1996) to establish solubility controls on Np in oxidizing groundwaters (including J-13 groundwater) starting from high concentrations (i.e., supersaturation) have shown the formation of one or both of two Np(V) phases, NaNpO2CO… more

We review the status of such data in light of the most recently reported experimental results. The focus is on the solid phases that may control solubilities under expected conditions in and near a potential nuclear waste repository at Yucca Mountain, Nevada. Solubility data or reliable predictions over the temperature range 20 to 150{degrees}C will be used in geochem… more

Polymeric Species of Pu in Low Ionic Strength Media

Description: The US Government has declared that approximately 50 tons of plutonium is surplus to US needs and should be set aside for eventual disposition. The US is currently following a dual path for the disposition of this plutonium: immobilization and irradiation of mixed-oxide fuel. Some fraction of this plutonium material that is undesirable for use in mixed-oxide fuel will be immobilized in a titanate ceramic and disposed of in a geologic repository for high level waste. The reminder of Pu will be f… more

Effects of Flaming Gorge Dam hydropower operations on downstream flow, stage, and sediment transport

Description: Hydropower operations at Flaming Gorge Dam, located on the Green River in Utah, can produce rapid downstream changes in flow and stage. These changes can in turn affect sediment transport and ecologic resources below the dam. To evaluate these effects, four hydropower operational scenarios with varying degrees of hydropower-release fluctuations were examined. This study demonstrates that the combined use of river-flow routing, water-surface profile, and sediment-transport models can provide use… more

Financial Analysis of Experimental Releases Conducted at Glen Canyon Dam During Water Year 2011

Description: This report examines the financial implications of experimental flows conducted at the Glen Canyon Dam (GCD) in water year 2011. It is the third report in a series examining financial implications of experimental flows conducted since the Record of Decision (ROD) was adopted in February 1997 (Reclamation 1996). A report released in January 2011 examined water years 1997 to 2005 (Veselka et al. 2011), and a report released in August 2011 examined water years 2006 to 2010 (Poch et al. 2011). An e… more

Financial Analysis of Experimental Releases Conducted at Glen Canyon Dam During Water Years 2006 Through 2010.

Description: Because of concerns about the impact that Glen Canyon Dam (GCD) operations were having on downstream ecosystems and endangered species, the Bureau of Reclamation (Reclamation) conducted an Environmental Impact Statement (EIS) on dam operations (DOE 1996). New operating rules and management goals for GCD that had been specified in the Record of Decision (ROD) (Reclamation 1996) were adopted in February 1997. In addition to issuing new operating criteria, the ROD mandated experimental releases fo… more

Combine Studies Pertaining to the Solubility of Neptunium in Oxidizing Aqueous Systems

Description: The report combines two separate studies dealing with different aspects of the behavior of neptunium in oxidizing aqueous systems. The goal of both studies is to obtain a better understanding of what would control the concentration of neptunium in oxidizing groundwaters upon release from a geologic high-level waste repository. {sup 237}Np has a very long half-life, and consequently tends to appear as a component of concern in long-term dose calculations.
