Methodology for evaluation of post-accidental rehabilitation strategies
IPSN/DPRE/SERGR/LESTS, BP. 6, 92265 Fontenay-aux-Roses cedex, France
Post-accidental management aims at restoring acceptable life conditions for population on sanitary, social and economic aspects. It is then a matter for an optimisation process in a multicriteria context, which has to combine quantitative parameters as well as qualitative parameters. In order to fit with this problematic, IPSN has developed and applied a methodology to a major accident situation on a reactor. The methodology consists in making a systematic evaluation of indicators in order to provide intercomparing data for many rehabilitation strategies. The methodology relies on four steps: characterisation of the geographic and demographic environment, radiological diagnosis, selection of countermeasures from a well characterised set of techniques, and last, evaluation of the intercomparing factors. For each selected countermeasures, radiological benefit and some incidences have been calculated: duration of realisation of the countermeasure, materials and human means, worker doses, amount and characteristics of generated wastes. In this context, calculations highlighted the importance of external exposure in built areas, and consequently the importance of the corresponding countermeasures. This work is a useful contribution to the clarification of the post-accidental rehabilitation problem.
