Validation of DWPF Melter Off-Gas Combustion Model
  • A. Choi
  • Materials Science
  • 23 August 2000
The empirical melter off-gas combustion model currently used in the DWPF safety basis calculations is valid at melter vapor space temperatures above 570 degrees C, as measured in the thermowell. ThisExpand

Calculation of DWPF Canister Decay Heat for Sludge Macro-Batches 1B to 9
  • A. Choi
  • Materials Science
  • 27 April 1999
The rates of heat generation of DWPF glass canisters due to radioactive decay have been estimated for the remaining nine macro-batches of sludge feed. The estimated decay heat ranged from 177.5 WattsExpand
Impact of Melter Internal Design on Off-Gas Flammability
The purpose of this study was to: (1) identify the more dominant design parameters that can serve as the quantitative measure of how prototypic a given melter is, (2) run the existing DWPF models toExpand
PHYSICAL PROPERTY MODELS OF CONCENTRATED CESIUM ELUATE SOLUTIONS
Major analytes expected to be present in the WTP cesium ion-exchange eluate solutions were identified from the available analytical data collected during radioactive bench-scale runs, and a testExpand

Methods of Off-Gas Flammability Control for DWPF Melter Off-Gas System at Savannah River Site
Several key operating variables affecting off-gas flammability in a slurry-fed radioactive waste glass melter are discussed, and the methods used to prevent potential off-gas flammability areExpand
Melter Off-Gas Flammability Assessment for DWPF Alternate Reductant Flowsheet Options
Glycolic acid and sugar are being considered as potential candidates to substitute for much of the formic acid currently being added to the Defense Waste Processing Facility (DWPF) melter feed as aExpand

Validation and Application of Concentrated Cesium Eluate Physical Property Models
This work contained two objectives. To verify the mathematical equations developed for the physical properties of concentrated cesium eluate solutions against experimental test results obtained withExpand
Maximum total organic carbon limit for DWPF melter feed
DWPF recently decided to control the potential flammability of melter off-gas by limiting the total carbon content in the melter feed and maintaining adequate conditions for combustion in the melterExpand
