摘要

The following standard has been published: ANSI/ANS-18.1-2016, Radioactive Source Term for Normal Operation of Light Water Reactors (supersedes ANSI/ANS-18.1-1999). This standard provides a set of typical radionuclide concentrations for estimating the radioactivity in the principal fluid systems of light-water reactors and for projecting the expected releases of radioactivity from nuclear plants. It is not intended that the values be used as the sole basis for design but rather that they be used in environmental reports and elsewhere where expected operating conditions over the life of the plant would be appropriate.
