Closeout of Advanced Boron and Metal Loaded High Porosity Carbons.

Date: May 1, 2011
Creator: (deceased), Peter C. Eklund; Chung, T. C. Mike; Foley, Henry C. & Crespi, Vincent H.
Description: The Penn State effort explored the development of new high-surface-area materials for hydrogen storage, materials that could offer enhancement in the hydrogen binding energy through a direct chemical modification of the framework in high specific-surface-area platforms. The team chemically substituted boron into the hexagonal sp2 carbon framework, dispersed metal atoms bound to the boro-carbon structure, and generated the theory of novel nanoscale geometries that can enhance storage through chemical frustration, sheet curvature, electron deficiency, large local fields and mixed hybridization states. New boro-carbon materials were synthesized by high temperature plasma, pyrolysis of boron-carbon precursor molecules, and post-synthesis modification of carbons. Hydrogen uptake has been assessed, and several promising leads have been identified, with the requirement to simultaneously optimize total surface area while maintaining the enhanced hydrogen binding energies already demonstrated.

Acute Toxicity and Bioaccumulation of Chloroform to Four Species of Freshwater Fish

Acute Toxicity and Bioaccumulation of Chloroform to Four Species of Freshwater Fish

Date: August 1, 1980
Creator: ,
Description: Acute toxicity of chloroform to four species of freshwater fish was studied in flow-through 96-hr toxicity tests. Chloroform is toxic to fish in the tens of parts per million, a concentration well above that which would be expected to be produced under normal power plant chlorination conditions. Investigations of acute toxicity of chloroform and the bioaccumulation of chlorinated compounds in tissues of fish revealed differences in tolerance levels and tissue accumulations. Mean 96-hr LC{sub 50}s for chloroform were 18 ppm for rainbow trout and bluegill, 51 ppm for largemouth bass and 75 ppm for channel catfish. Mortalities of bluegill and largemouth bass occurred during the first 4 hr of exposure while rainbow trout and channel catfish showed initial tolerance and mortalities occurred during the latter half of the 96-hr exposure. Rainbow trout had the highest level of chloroform tissue accumulation, 7 {micro}g/g tissue, catfish the second highest, 4 {micro}g/g tissue, followed by bluegill and largemouth bass which each accumulated about 3 {micro}g/g tissue. Accumulation of chloroform was less than one order of magnitude above water concentrations for all species.

Chronic Effects of Chlorination By-Products on Rainbow Trout, Salmo gairdneri

Chronic Effects of Chlorination By-Products on Rainbow Trout, Salmo gairdneri

Date: November 1, 1980
Creator: ,
Description: Rainbow trout were exposed to by-products of low-level water chlorination for several months in two separate experiments. In each test 2400 juvenile rainbow trout (Salmo gairdneri) were reared under chlorination conditions designed to simulate those of a power plant. Objectives were to determine effects of long term exposure to provide samples for tissue analysis of chlorination byroducts. No significant difference in fish condition factors was found between the test groups and controls, neither was there an apparent effect on mortality. Background levels of chloroform were found in all fish, but there was no evidence of an increased amount of chloroform or other chlorination by-products resulting from chronic low level exposure to chlorination by-products.

Estimated Incremental Costs for NRC Licensees to Implement the US/IAEA Safeguards Agreement

Estimated Incremental Costs for NRC Licensees to Implement the US/IAEA Safeguards Agreement

Date: July 19, 1979
Creator: ,
Description: At the request of the U.S. Nuclear Regulatory Commission (NRC), the Pacific Northwest Laboratory (PNL), operated by Battelle Memorial Institute for the Department of Energy, conducted a brief study to identify the incremental cost for implementing the US/IAEA safeguards treaty agreement. The purpose of the study was to develop an estimate of the cost impact to eligible NRC licensees for complying with the proposed Part 75 of Title 10, Code of Federal Regulations (10 CFR 75), the rule which will implement the treaty. The study was conducted using cost estimates from several eligible licensees who will be affected by the agreement and from cost analyses by PNL staff. A survey instrument was developed and sent to 25 NRC licensees, some of whom had more than one licensed facility. Their responses were obtained primarily by telephone after they had reviewed the survey insttument and a list of assumptions. The primary information received from the licensees was the incremental cost to their particular facility in the form of manpower, dollars or both. In summary, the one-time cost to all eligible NRC licensees to implement 10 CFR 75 is estimated by PNL to range from $1.9 to $7.2 millions. The annual cost to ...

Mathematical Simulation of Sediment and Radionuclide Transport in Surface Waters

Mathematical Simulation of Sediment and Radionuclide Transport in Surface Waters

Date: April 1, 1981
Creator: ,
Description: The study objective of "The Mathematical Simulation of Sediment and Radionuclide Transport in Surface Waters" is to synthesize and test radionuclide transport models capable of realistically assessing radionuclide transport in various types of surface water bodies by including the sediment-radionuclide interactions. These interactions include radionuclide adsorption by sediment; desorption from sediment into water; and transport, deposition, and resuspension of sorbed radionuclides controlled by the sediment movements. During FY-1979, the modification of sediment and contaminant (radionuclide) transport model, FETRA, was completed to make it applicable to coastal waters. The model is an unsteady, two-dimensional (longitudinal and lateral) model that consists of three submodels (for sediment, dissolved-contaminant, and particulate-contaminant transport), coupled to include the sediment-contaminant interactions. In estuaries, flow phenomena and consequent sediment and radionuclide migration are often three-dimensional in nature mainly because of nonuniform channel cross-sections, salinity intrusion, and lateral-flow circulation. Thus, an unsteady, three-dimensional radionuclide transport model for estuaries is also being synthesized by combining and modifying a PNL unsteady hydrothermal model and FETRA. These two radionuclide transport models for coastal waters and estuaries will be applied to actual sites to examine the validity of the codes.

MODIFIED FINITE ELEMENT TRANSPORT MODEL, FETRA, FOR SEDIMENT AND RAOIONUCLIDE MIGRATION IN OPEN COASTAL WATERS

MODIFIED FINITE ELEMENT TRANSPORT MODEL, FETRA, FOR SEDIMENT AND RAOIONUCLIDE MIGRATION IN OPEN COASTAL WATERS

Date: August 1, 1979
Creator: ,
Description: The finite element model, FETRA, simulates transport of sediment and radionuclides (and other contaminants, such as heavy metals, pesticides, and other toxic substances) in surface water bodies. The model is an unsteady, two-dimensional (longitudinal and lateral} model which consists of the following three submodels coupled to include sediment-contaminant interactions: 1) sediment transport submodel, 2} dissolved contaminant transport submodel, and 3) particulate contaminant (contaminant adsorbed by sediment) transport submodel. Under the current phase of the study, FETRA was modified to include sediment-wave interaction in order to extend the applicability of the model to coastal zones and large lakes (e.g., the Great Lakes) where wave actions can be one of the dominant mechanisms to transport sediment and toxic contaminant. FETRA was further modified to handle both linear and quadratic approximations to velocity and depth distributions in order to be compatible with various finite element hydrodynamic models (e.g., RMA II and CAFE) which supply hydrodynamic input data to FETRA. The next step is to apply FETRA to coastal zones to simulate transport of sediment and radionuclides with their interactions in order to test and verify the model under marine and large lacustrine environments.

Preliminary Results from an Investigation into Nanostructured Nuclear Radiation Detectors for Non-Proliferation Applications

Preliminary Results from an Investigation into Nanostructured Nuclear Radiation Detectors for Non-Proliferation Applications

Date: October 1, 2012
Creator: ,
Description: In recent years, the concept of embedding composite scintillators consisting of nanosized inorganic crystals in an organic matrix has been actively pursued. Nanocomposite detectors have the potential to meet many of the homeland security, non-proliferation, and border and cargo-screening needs of the nation and, by virtue of their superior nuclear identification capability over plastic, at roughly the same cost as plastic, have the potential to replace all plastic detectors. Nanocomposites clearly have the potential of being a gamma ray detection material that would be sensitive yet less expensive and easier to produce on a large scale than growing large, whole crystals of similar sensitivity. These detectors would have a broad energy range and a sufficient energy resolution to perform isotopic identification. The material can also be fabricated on an industrial scale, further reducing cost. This investigation focused on designing and fabricating prototype core/shell and quantum dot (QD) detectors. Fourteen core/shell and four QD detectors, all with the basic consistency of a mixture of nanoparticles in a polymer matrix with different densities of nanoparticles, were prepared. Nanoparticles with sizes <10 nm were fabricated, embedded in a polystyrene matrix, and the resultant scintillators’ radiation detector properties were characterized. This work also attempted ...

A Procedure for the Qualitative Interpretation of Fuel Centerline Thermocouple Response to Step-Power Decreases

Date: October 1, 1979
Creator: ,
Description: This report reviews the present calculational techniques that may be used to interpret the transient response of fuel centerline thermocouples to step decreases in rod power. A new technique developed herein involves plotting the natural logarithm of the normalized thermocouple data versus time, plotting various calculations in the same way, and observing the curvature of the resulting lines. Also described is the small computer code, MWRAM, which facilitates testing various models against transient data. Transient data from IFA-513 is presented. This test assembly in the Halden Reactor, Norway, is jointly sponsored by the Nuclear Regulatory Commission and the Halden Project. A comparison of MWRAM calculations with this data has shown that fuel cracking appears to greatly influence the heat transfer modes in the fuel rod. A method of estimating the effective fuel-cladding gap size from this transient data is also discussed in this report .

Saturation and Dynamic Range of Microchannel Plate-Based X-Ray Imagers

Saturation and Dynamic Range of Microchannel Plate-Based X-Ray Imagers

Date: May 4, 2012
Creator: ,
Description: This paper describes recent advances in Monte Carlo simulations of microchannel plate (MCP)–based x-ray detectors, a continuation of ongoing work in this area. A Monte Carlo simulation model has been developed over the past several years by National Security Technologies, LLC (NSTec). The model simulates the secondary electron emission process in an MCP pore and includes the effects of gain saturation. In this work we focus on MCP gain saturation and dynamic range. We have performed modeling and experimental characterizations of L/D = 46, 10-micron diameter, MCP-based detectors. The detectors are typically operated by applying a subnanosecond voltage pulse, which gates the detector on. Agreement between the simulations and experiment is very good for a variety of voltage pulse waveforms ranging in width from 150 to 300 ps. The results indicate that such an MCP begins to show nonlinear gain around 5 × 10^4 electrons per pore and hard saturation around 105 electrons per pore. The simulations show a difference in MCP sensitivity vs voltage for high flux of photons producing large numbers of photoelectrons on a subpicosecond timescale. Simulations and experiments both indicate an MCP dynamic range of 1 to 10,000, and the dynamic range depends on how the ...

Site-Directed Research and Development FY 2012 Annual Report

Date: April 1, 2013
Creator: ,
Description: The reports included in this report are for project activities that occurred from October 2011 through September 2012. These reports describe in detail the discoveries, achievements, and challenges encountered by our talented and enthusiastic principal investigators (PIs). Many of the reports describe R&D efforts that were “successful” in their pursuits and resulted in a positive outcome or technology realization. As we’ve stated before, and continue to stress, in some cases the result is a “negative” finding, for instance a technology is currently impractical or out of reach. This can often be viewed erroneously as a “failure,” but is actually a valid outcome in the pursuit of high-risk research, which often leads to unforeseen new paths of discovery. Either result advances our knowledge and increases our ability to identify solutions and/or likewise avoid costly paths not appropriate for the challenges presented. The SDRD program continues to provide an unfettered mechanism for innovation and development that returns multifold to the NNSS mission. Overall the program is a strong R&D innovation engine, benefited by an enhanced mission, committed resources, and sound competitiveness to yield maximum benefit. The 23 projects described exemplify the creativity and ability of a diverse scientific and engineering talent base. ...
