Final Report: Theoretical Studies on Radiation-Induced Transformations in Nucleic Acid Bases, May 1, 1993 - April 30, 1996

Description: In the proposal we identified several elemental molecular properties related to the effects observed in genetic material exposed to ionizing irradiation, and we studied them by means of the ab-initio quantum chemistry. The chemistry of irradiation is complex and biological consequences are significant. This includes cell death, mutations, carcinogenic transformations, etc. In the proposal we theoretically modeled several elemental processes related to the radiolysis of components of the nucleic… more

Parametric electric motor study

Description: Technology for the axial gap motor was developed by DOE with an investment of approximately $15 million. This development effort is for motor technologies of high power density and high efficiency. Such motors that are also small and light-weight are not available on the commercial market because high-power motors have typically been used in large industrial applications where small size and light weight are not requirements. AC Delco has been developing motors since 1918 and is interested in l… more

Solid-State Fault Current Limiter Development : Design and Testing Update of a 15kV SSCL Power Stack

Description: ABSTRACT The Solid-State Fault Current Limiter (SSCL) is a promising technology that can be applied to utility power delivery systems to address the problem of increasing fault currents associated with load growth. As demand continues to grow, more power is added to utility system either by increasing generator capacity or by adding distributed generators, resulting in higher available fault currents, often beyond the capabilities of the present infrastructure. The SSCL is power-electronics bas… more

PFP solution stabilization

Description: This Functional Design Criteria (FDC) addresses remediation of the plutonium-bearing solutions currently in inventory at the Plutonium Finishing Plant (PFP). The recommendation from the Environmental Impact Statement (EIS) is that the solutions be treated thermally and stabilized as a solid for long term storage. For solutions which are not discardable, the baseline plan is to utilize a denitration process to stabilize the solutions prior to packaging for storage.

Hydrogen Storage in metal-modified single-walled carbon nanotubes

Description: It has been known for over thirty years that potassium-intercalated graphites can readily adsorb and desorb hydrogen at {approx}1 wt% at 77 K. These levels are much higher than can be attained in pure graphite, owing to a larger thermodynamic enthalpy of adsorption. This increased enthalpy may allow hydrogen sorption at higher temperatures. Potassium has other beneficial effects that enable the design of a new material: (a) Increased adsorption enthalpy in potassium-intercalated graphite compar… more

Project Work Plan 100-N Area Strontium-90 Treatability Demonstration Project: Phytoremediation Along the 100-N Columbia River Riparian Zone

Description: The 100-N Area Innovative Treatment and Remediation Demonstration (ITRD) identified phyto¬remediation as a potential technology both for the removal of 90Sr from the soil of the riparian zone and as a filter for groundwater along the Columbia River. Recent greenhouse and growth chamber studies have demonstrated the viability of phytoextraction to remove 90Sr from this area’s soil/water; in conjunction with monitored natural attenuation and an apatite barrier the process would make an effective … more

Increased oil production and reserves utilizing secondary/tertiary recovery techniques on small reservoirs in the Paradox Basin, Utah. Technical progress report, January 1--March 31, 1996

Description: The primary objective of this project is to enhance domestic petroleum production by demonstration and technology transfer of an advanced oil recovery technology in the Paradox basin, southeastern Utah. If this project can demonstrate technical and economic feasibility, the technique can be applied to approximately 100 additional small fields in the Paradox basin alone, and result in increased recovery of 150 to 200 million barrels of oil. This project is designed to characterize five shallow-s… more

C reactor overbore fuel failures

Description: The concept of overboring the graphite channels in an older Hanford reactor and installing oversized tubes charged with oversize fuel elements is being investigated at C reactor. Recently a column of these oversized test fuel elements exhibited three uranium cleavage (split) type failures after experiencing severe reactor flux cycling. This report presents a preliminary description of both the fuel failures and the flux cycling encountered by the reactor.

Budget for FY 1971 and revision of FY 1970 Douglas United Nuclear, Inc. , 02 research and development

Description: The Richland 02 Five-Year Process Development Program has been divided into 10 missions. The missions by title were: Basic Production; Coproduct; Transplutonium; Pu-238; Other Isotopes; Enriched Fuel Processing Target Space Enhancement Nuclear Safety; Waste Management; and Columbia River Studies. Although in general most of the same efforts are incorporated, the mission concept is being dropped, and the following designations for programs have been adopted: Basic Production; Product Flexibility… more

Nonlinear Projective-Iteration Methods for Solving Transport Problems on Regular and Unstructured Grids

Description: This is a project in the field of fundamental research on numerical methods for solving the particle transport equation. Numerous practical problems require to use unstructured meshes, for example, detailed nuclear reactor assembly-level calculations, large-scale reactor core calculations, radiative hydrodynamics problems, where the mesh is determined by hydrodynamic processes, and well-logging problems in which the media structure has very complicated geometry. Currently this is an area of ver… more

CUREBO: A GENERALIZED TWO-SPACE-DIMENSIONAL CODING WITH CROSS-SECTION AND DEPLETION CALCULATIONS FOR THE IBM 704

Description: The CUREBO code for the IBM 704 is described. The code is divided into three parts including the calculation of nuclear cross section of the various physical components of a reactor (WOX7), the solution of the multigroup diffusion equations in two-space dimensions in order to find neutron fluxes and sources for an operating reactor containing these components ( CURE), and the calculation of fuel and poison depletion as a result of operating this reactor under steady- state conditions (BO2).

Irradiation Testing of Operating Electronic Equipment by Fast Neutrons and Gammas. Final Report

Description: A study of the radiation effects of fast neutrons (O.5 ev to about 15 Mev) and gamma rays (fission spectrum) on various pieces of aircraft instrumentation is re ported. Components studied were: fuel gage vacuumtube amplifier and indicator, transistorized (germanium and silicon) servo amplifier system, and 4-in. diam. gyro. The fuel gage was subjected to a total neutron flux of about 6 x 1O/sup 5/nvt and about 5 x 1Osup 8/ r gamma with no adverse electrical effect. Physical damage was evident. F… more

Gundrilling Oil Evaluation to Find a Replacement for 50-50

Description: In 2006 the gundrilling oil used at Honeywell FM&T (Federal Manufacturing and Technology) was known as 50-50. This name was selected because the oil is a mixture of two machining oils, Milpro 634 and Pennex N47. Unfortunately, Honeywell FM&T was notified that one component, Pennex N47, would be discontinued by the manufacturer. At this point the Honeywell FM&T team decided to select a single oil to eliminate mixing and procurement of two products. In addition, the team also wanted to select new… more
