Abstract:
One of the aims in the design of the COSYMA ingestion model was the ability to cope in a flexible manner with the various food chain related data and results at different stages of an accident consequence assessment.
Since dynamic foodchain transport models themselves are normally rather complex and require significant computing times, they are usually not included in ACA codes, but are used to calculate and tabulate the needed information in the form of data libraries. Such data files contain specific activity concentrations in the foodstuffs and their time integrals normalized to unit deposit or unit air concentration for a series of times after the accident to allow for calculations taking account of food restrictions. In an ACA run, the actual specific concentrations in the foodstuffs are obtained by multiplying the normalized concentrations taken from the data library by the ground or air concentrations in each grid point predicted with an atmospheric transport and deposition model.
The paper presents the structure of the ingestion model: structure, methods and the libraries used for a nuclear accident consequences assessment.
