Offsite dose calculations for hypothetical fusion facility accidents
The FUSCRAC3 code has been developed to assess offsite consequences of potential fusion reactor accidents. Exposure pathways include inhalation, cloudshine, groundshine and ingestion. For most pathways, offsite doses can be assessed for 259 isotopes, including tritium as HTO. The ingestion model handles 145 isotopes, which may enter the food chain and be of metabolic importance. Both acute and chronic exposures can be evaluated. The acute dose is that incurred during and shortly after plume passage and includes contributions from cloudshine during plume passage, seven days of groundshine, and the committed dose over an organ-dependent critical time period due to inhalation during plume passage. Early fatalities are assessed on the basis of acute radiation exposure to the bone marrow, lungs, and lower large intestinal wall. Early injuries or illnesses are evaluated on the same basis. The chronic dose includes the 50-year dose commitment from inhalation during plume passage and of resuspended material, the 50-year dose commitment from ingestion of contaminated foodstuffs, and the dose from long term groundshine. Latent cancer fatalities may occur as a result of early or chronic radiation exposure. These are estimated using a linear relationship between doses and latent cancer cases. The chronic whole body dose to the population in the area surrounding the facility can also be determined. 18 refs., 3 figs., 8 tabs.
