Environmental Effects of Fusion Power Plants. Part III: Potential Radiological Impact of Environmental Releases

Releases of tritium and activation products from a reference fusion reactor under normal operating conditions were evaluated for the radiation doses to local and global populations. Maximum annual total body dose commitment from all sources of effluents to an individual at the plant boundary is 0.5 mrems. The annual total body dose commitment from all effluents to the population of 1 million persons living within 80 km of the plant is 7 person-rems. These exposures are small fractions of the doses resulting from existing background radiation. Global doses due to tritium and ¹⁴C releases from the reference fusion reactor are small fractions of doses resulting from naturally occurring tritium and ¹⁴C.
