FY99 Status Report on the HSV

'The HSV in storage in MTF has been monitored during FY99, and its overpressure has been sampled and analyzed. The HSV''s internal pressure continues to rise slowly, and the overpressure still analyzes as 100 percent 3He. The titanium tritide sample that was to be monitored annually and which had developed a leak last year has been repaired and isotherms measured. Unfortunately the sample was showing significant unexpected 3He release, so the isotherm data is corrupted by unknown levels of 3He. This release has disqualified this sample for future use, as it is now seriously divergent from the HSV material. A different sample must be selected for subsequent studies.The unexpected 3He releases of the Ti-3 sample and the possible release in other Ti samples have raised a serious issue. It should be determined why this release is occurring, so that an unexpected release of 3He during HSV unloading can be assessed as unlikely.'

Vector Potential and Stored Energy of a Quadrupole Magnet Array (open access)

Vector Potential and Stored Energy of a Quadrupole Magnet Array

The vector potential, magnetic field and stored energy of a quadrupole magnet array are derived. Each magnet within the array is a current sheet with a current density proportional to the azimuthal angle 2{theta} and the longitudinal periodicity (2m-1){pi}/L. Individual quadrupoles within the array are oriented in a way that maximizes the field gradient The array does not have to be of equal spacing and can be of a finite size, however when the array is equally spaced and is of infinite size the solution can be simplified. We note that whereas, in a single quadrupole magnet with a current density proportional to cos2{theta} the gradient is pure, such purity is not preserved in a quadrupole array.

Pend Oreille Wetlands Wildlife Mitigation Project Management Plan for the "Dilling Addition". (open access)

Pend Oreille Wetlands Wildlife Mitigation Project Management Plan for the "Dilling Addition".

This report is a recommendation from the Kalispel Tribe to the Bonneville Power Administration (BPA) and the Columbia Basin Fish and Wildlife Authority (CBFWA) for management of the Pend Oreille Wetland Wildlife Mitigation project II (Dilling Addition) for the extensive habitat losses caused by Albeni Falls Dam on Kalispel Ceded Lands. Albeni Falls Dam is located on the Pend Oreille River near the Washington-Idaho border, about 25 miles upstream of the Kalispel Indian Reservation. The dam controls the water level on Lake Pend Oreille. The lake was formerly the center of subsistence use by the Kalispel Tribe. Flooding of wetlands, and water fluctuations both on the lake and downstream on the river, has had adverse impacts to wildlife and wildlife habitat. An extensive process was followed to formulate and prioritize wildlife resource goals. The Kalispel Natural Resource Department provided guidance in terms of opportunities onsite. To prioritize specific goals, the Albeni Falls Interagency Work Group and the Columbia Basin Fish and Wildlife Authority Wildlife Caucus were consulted. From this process, the top priority goal for the Kalispel Tribe is: Protect and develop riparian forest and shrub, and freshwater wetlands, to mitigate losses resulting from reservoir inundation and river level fluctuations …

EQ6 Calculations for Chemical Degradation of Navy Waste Packages (open access)

EQ6 Calculations for Chemical Degradation of Navy Waste Packages

The Monitored Geologic Repository Waste Package Operations of the Civilian Radioactive Waste Management System Management & Operating Contractor (CRWMS M&O) performed calculations to provide input for disposal of spent nuclear fuel (SNF) from the Navy (Refs. 1 and 2). The Navy SNF has been considered for disposal at the potential Yucca Mountain site. For some waste packages, the containment may breach (Ref. 3), allowing the influx of water. Water in the waste package may moderate neutrons, increasing the likelihood of a criticality event within the waste package. The water may gradually leach the fissile components and neutron absorbers out of the waste package. In addition, the accumulation of silica (SiO{sub 2}) in the waste package over time may further affect the neutronics of the system. This study presents calculations of the long-term geochemical behavior of waste packages containing the Enhanced Design Alternative (EDA) II inner shell, Navy canister, and basket components. The calculations do not include the Navy SNF in the waste package. The specific study objectives were to determine the chemical composition of the water and the quantity of silicon (Si) and other solid corrosion products in the waste package during the first million years after the waste package …

HLW Canister and Can-In-Canister Drop Calculation (open access)

HLW Canister and Can-In-Canister Drop Calculation

The purpose of this calculation is to evaluate the structural response of the standard high-level waste (HLW) canister and the HLW canister containing the cans of immobilized plutonium (''can-in-canister'' throughout this document) to the drop event during the handling operation. The objective of the calculation is to provide the structure parameter information to support the canister design and the waste handling facility design. Finite element solution is performed using the commercially available ANSYS Version (V) 5.4 finite element code. Two-dimensional (2-D) axisymmetric and three-dimensional (3-D) finite element representations for the standard HLW canister and the can-in-canister are developed and analyzed using the dynamic solver.

Guidelines for the Calculation of the Accumulator Magnet Bus Ramps for Fermilab Experiment E835 (open access)

Guidelines for the Calculation of the Accumulator Magnet Bus Ramps for Fermilab Experiment E835

This report lists the steps that are required to calculate deceleration ramps for all relevant Accumulator devices. The ramps used for the 1996-97 fixed target run (experiment E835) are saved in files associated with ACNET console application PA1627 (PAUX RAMP DEVELOP). These ramps cannot be re-used because the Accumulator {gamma}{sub t} upgrade has significantly changed the lattice since the last time the ramps were used. Consequently, new deceleration ramps must be calculated and commissioned before the next fixed target run. The deceleration ramp for a particular device is a table that gives the sequence of set values sent to the device as the ramp is executed. The 1997 ramps consist of ramp tables for 100 devices. Appendix 1 gives a list of the devices ramped. Most of these devices will still require ramps for the next fixed target run. Future decelerations will also require ramps for the quadrupole magnet shunts that were installed as part of the {gamma}{sub t} upgrade. Additionally, ramps must be constructed for the two skew-sextupole magnets that will be installed during the summer of 1999.

Nanomaterials in Secondary Battery Development (open access)

Nanomaterials in Secondary Battery Development

This granted funded research into the application of nanoscience to Li-ion batteries. Different synthesis strategies were employed to create a nanofiber electrode (based on tin-oxide) and a honeycomb electrode (carbon). In both cases, we showed that the nanostructured material was capable of delivering dramatically increased specific capacity (mAh/g) upon discharge when compared to conventional film electrodes. This ability is due to the decreased solid-state diffusion distance of the Li-ion in the nanostructured electrodes. The nanofiber-SnO{sub 2} electrode was created by the template synthesis method. Briefly, a precursor solution impregnates the monodisperse nanoscopic pores of a sacrificial template membrane. The pores run the membrane's entire length. The precursor solution is then processed to the desired material, here using sol-gel chemistry, and the template is removed. This leaves nanostructures of the desired product intact and extending from a substrate like the bristles of a brush. This research topic combines this nanofabrication technique with the Sn-based anode. Tin-oxide based composites have shown great promise as an alternative material for Li-ion battery anodes. This material is electrochemically converted to composite Sn/LiO{sub 2} electrodes. In this form, they are theoretically capable of storing twice the amount of Li as carbon, the current commercial anode. We …

Effects of processing conditions and ambient environment on the microstructure and fracture strength of copper/niobium/copper interlayer joints for alumina (open access)

Effects of processing conditions and ambient environment on the microstructure and fracture strength of copper/niobium/copper interlayer joints for alumina

Partial transient liquid phase (PTLP) bonding is a technique which can be used to join ceramics with metals and is used to form niobium-based joints for alumina. The principal advantage to PTLP bonding is that it enables refractory joints to be fabricated at temperatures below those typically required by solid state diffusion bonding. A thorough review of the important parameters (chemical compatibility, thermal expansion match, sufficient wettability of the liquid phase on the solid phases) in choosing a joining material for ceramics by the PTLP method is provided. As in conventional PTLP joining, the current study uses thin (=3 (mu)m) copper layers sandwiched between the alumina (bulk) and niobium (127 (mu)m). However, unlike the case of copper/nickel/copper obium is limited. Consequently, the copper is not entirely dissolved in the process, resulting in a two phase (copper-rich and niobium-rich phases) microstructure. Different processing conditions (temperature and applied load) result in different morphologies of the copper-rich and niobium-rich phases at the interface. These different microstructures exhibit distinct strength characteristics. Extended annealing of as-processed joints can influence the strengths differently depending on the ambient partial oxygen pressure at the annealing temperature. The focus of this work is to correlate processing conditions, microstructure, and …
