Testing Report: Littleford-Day Dryer Operation: Dryer Operation Impacts of Proposed MIS Mitigation Changes
Pacific Northwest National Laboratory performed a series of tests using the Littleford Day 22-liter dryer during investigations that evaluated changes in the melter-feed composition for the Demonstration Bulk Vitrification System. During testing, a new melter-feed formulation was developed that improved dryer performance while improving the retention of waste salts in the melter feed during vitrification
Inflation from Susy quantum cosmology
We propose a realization of inverted hybrid inflation scenario in the context
of n=2 supersymmetric quantum cosmology. The spectrum of density fluctuations
is calculated in the de Sitter regimen as a function of the gravitino and the
Planck mass, and explicit forms for the wave function of the universe are found
in the WKB regimen for a FRW closed and flat universes.Comment: 9 pages, one figure, to appear in Phys. Rev.
HWVP pilot-scale vitrification system campaign: LFCM-8 summary report
The Hanford Waste Vitrification Plant (HWVP) is being designed to treat the high-level radiative waste (HLW) stored in underground storage tanks as an alkaline sludge. Tank waste will first be retrieved and pretreated to minimize solids requiring vitrification as HLW. The glass product resulting from HWVP operations will be stored onsite in stainless steel canisters until the HLW repository is available for final disposal. The first waste stream scheduled to be processed by the HWVP is the neutralized current acid waste (NCAW) stored in double-shell storage tanks. The Pacific Northwest Laboratory (PNL) is supporting Westinghouse Hanford Company (WHC) by providing research, development, and engineering expertise in defined areas. As a part of this support, pilot-scale testing is being conducted to support closure of HWVP design and development issues. Testing results will verify equipment design performance, establish acceptable and optimum process parameters, and support product qualification activities
Spin Effects in Two Quark System and Mixed States
Based on the numeric solution of a system of coupled channels for vector
mesons (- and -waves mixing) and for tensor mesons (- and -waves
mixing) mass spectrum and wave functions of a family of vector mesons
in triplet states are obtained. The calculations are performed using
a well known Cornell potential with a mixed Lorentz-structure of the
confinement term. The spin-dependent part of the potential is taken from the
Breit-Fermi approach. The effect of singular terms of potential is considered
in the framework of the perturbation theory and by a configuration interaction
approach (CIA), modified for a system of coupled equations. It is shown that
even a small contribution of the -wave to be very important at the
calculation of certain characteristics of the meson states.Comment: 12 pages, LaTe

Detailed Design Data Package item 3.9a: Cadmium buildup in off-gas lines
Waste currently stored at the Hanford Reservation in underground double-shell and single-shell tanks is being considered for vitrification and disposal. To achieve this, Hanford is conducting a Hanford Waste Vitrification Plant Technology Development Project melter campaign. In this campaign, a requirement was identified to quantify the amount of cadmium depositing in the off-gas line between the liquid-fed ceramic melter and the submerged bed scrubber. This issue of cadmium volatility was raised due to the limited data on cadmium volatility in HLW vitrification. Prior to the start of slurry processing, the off-gas line sections were removed and inspects. Any pre-existing deposits were removed. Following the melter campaign, the lines were again removed and solids deposits were sampled and the quantity of deposits were estimated. The data presented in this package include chemical analysis of feed, glass, line deposits, in-ling off-gas stream, and SBS condensate samples. Process data includes melter feeding and glass production rates, off- gas flow rate, and plenum and off-gas stream temperatures
