Exploitation of Particle Filter in Early Phase of a Reactor Accident
Original language description
Exploitation of the data assimilation methodology in the field of radiation protection is studied. When radioactive pollutants are released into the atmosphere, a radioactive plume is passing over the terrain. In order to ensure efficiency of introducedcountermeasures, it is necessary to predict spatial and temporal distribution of aerial pollution and material already deposited on the ground. The predictions are made by the means of numerical dispersion models with many inputs. A group of the most significant input parameters affecting the dispersion process was selected using sensitivity and uncertainty studies performed on dispersion models. Exact values of these parameters are uncertain due to the stochastic nature of atmospheric dispersion, hencethe parameters are modeled as random quantities. Data assimilation is the optimal way how to exploit information from both the measured data and expert-selected prior knowledge to obtain reliable estimates of the input parameters.
