Survey of element and isotope importance for fusion safety and environmental assessments

A survey was made, using the most reliable information possible, to identify which elements and isotopes are potentially important for fusion safety and environmental assessments. It was determined that 51 elements may be exposed to fusion neutrons in either experimental devices or commercial reactors. These elements were prioritized by the relative probability of use. Also, 371 radioactive isotopes were identified that may be produced from these elements. These isotopes were prioritized by screening criteria that measured their relative importance to effluent assessments, accident assessments, and waste management assessments. Survey results presented in this report are prioritized lists of elements and isotopes of importance to neutronics researchers, effluent assessors, accident assessors, waste management assessors, maintenance assessors, and volatility and/or transport researchers. It is hoped that the results of this effort will lead to improved information in the various area, which in turn will lead to better safety and environmental assessments
