Practical Solutions to Radioactive Waste Characterization
The movement or storage of containers of radioactive waste requires characterization of the contents for radioactivity to verify conformance with transportation and waste acceptance controls. Spectroscopy of the emitted gamma rays is often the only viable method of assay of the contents. The spectrum analysis must include suitable efficiency, attenuation and geometry corrections for bulk contai...
متن کاملBayesian Uncertainty Quantification Applied to RANS Turbulence Models
A Bayesian uncertainty quantification approach is developed and applied to RANS turbulence models of fully-developed channel flow. The approach aims to capture uncertainty due to both uncertain parameters and model inadequacy. Parameter uncertainty is represented by treating the parameters of the turbulence model as random variables. To capture model uncertainty, four stochastic extensions of f...
متن کاملRadioactive analysis and radiological hazards of sand in Weifang, China
Background: The activity concentrations of 226Ra, 232Th and 40K in sand used as building material in Weifang of China were investigated for evaluating the radiation hazard. Materials and Methods: Sand samples were collected from Weifang and their radioactivity levels were measured using gamma-ray spectrometry. The radiation hazard for residents was assessed by radium equivalent activity (Raeq),...
متن کاملCharacterization of Radioactive Waste Drums by Non Destructive Gamma Spectrometry
Assay of the radioactive content of waste drums is important for inventory and waste disposal purposes. The sampling of the drum content is a difficult, time and labor consuming procedure, involving special radiation protection considerations. On the other hand the characterization of waste drums containing radioactivity by measuring the drum as a whole (without opening) offers overall simplici...
متن کاملDisposal of Radioactive Waste
Perhaps the most important single problem arising from the increasing use of atomic energy for peaceful purposes is how to dispose of the growing amounts of radioactive waste. Many of its complex aspects were discussed at the scientific conference on the disposal of radioactive waste held by IAEA in Monaco from 16 to 21 November 1959. The conference was organized jointly with UNESCO, with the c...
