Analysis and calculation of annual emissions of tritium for Daya Bay and Lingao nuclear power plants

This paper presents an effective methodology for calculation of annual emissions of tritium from PWR, which is in accordance with the principle of production, diffusion, permeation of tritium in PWR. According to this methodology and actual operating conditions and parameter of the Daya Bay and Ling Ao NPPs, calculation of the annual emissions of tritium is shown and proved reasonable and correct by comparison between values from calculation and measured data.
