Parametric study of accident consequences from different weather conditions. Application to IFE power plants

Estimating radiological risks is an essential part of an assessment of fusi on as an attractive source of energy. Due to the limited data specific to r adionuclides of interest to fusion reactors, one of the goals of this work is to expand the Dose Conversion Factors (DCF) library for use in the calcu lation of different types of off-site doses and associated health effect co nsequences. This expansion accounts for about 300 radionuclides included in accidental activity releases from HYLIFE-II and SOMBRERO IFE Power Plants. Furthermore, for each of the radionuclides included in the new DCF library , we address a parametric study of accident consequences by varying the atm ospheric stability, wind speed, rain conditions, and thermal plume rise. Th e results of these calculations allow us to identify the most troublesome r adionuclides in terms of safety consequences as well as the impact of the d ifferent atmospheric scenarios.
