Abstract

With a Monte Carlo code MCNPX and an activation calculation code FISPACT-2007, nuclear heart, radioactivity and shutdown dose rate for the breeding blanket of China fusion engineering test reactor (CFETR) have been calculated. The calculation results show that the total radioactivity is 2.34x1019Bq at shutdown after one year operation and the total radioactivity is 7.98x1018Bq which is 12.1% of the original radioactivity. Until the cooling time come to 2.6 years, 25.2 years and 46.4 years, respectively, tritium breeding material, neutron multiplier material and structure material can be remotely operated. The results show that there isn't serious environmental issue.
