Radiohygienic aspects of the safety analysis of the Puespoekszilagy radioactive waste disposal and treatment facility, Hungary

The new disposal facility for low and intermediate level radioactive waste was put into operation in Hungary in 1976. As the safety analysis was performed only in a simplified way in 1970's a comprehensive safety analysis was prescribed to get the license for the operation of the storage units extended at the end of 1980's. ETV-EROETERV Ltd. has performed the safety analysis involving the NRIRR into the biosphere characterisation of the region and the dose estimations for different accidental scenarios as well. The biosphere characterisation included meteorology, geography, land and water usage, demography, economic activity, and food consumption rate and health/epidemiological status of the population. The burning of waste as the most important accidental scenario considered indicated the ingestion of foodstuffs as the main exposure pathway and 90Sr as the critical radionuclide. (author)
