“…Tritium is generated by neutron capture and inelastic scattering from beryllium nuclides and its content in the waste stream will depend on the applied waste treatment technologies. 7 Be is produced from beryllium by 9 Be(n,3n) 7 Be reaction 82 .…”

“…In order to assess the radionuclide inventory, simulation was performed with MCNPX2.7 49 using ENDF/B-VII cross section libraries coupled with CINDER'90 31 similarly to the method of statement 3. I showed that at shutdown after 1-year operation the most active gamma-emitting isotopes are 56 Mn (1.8×10 9 Bq/cm 3 ) and 7 Be (9.7×10 8 Bq/cm 3 ). The dose rate on the external surface of the beryllium reflector after 1-year irradiation time is 720 Sv/h at the end of operation, decreasing to 60 mSv/h after 2 weeks cooling time.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
