Radiological impact of discharges

The calculated radiological impact of the maximum discharges in the EDF application dossiers for the most exposed population reference group remains well below the acceptable dosimetric limits for the public.

The annual effective dose received by the population reference group given in the EDF discharge and water intake licence applications is estimated at between a few microsieverts and a few tens of microsieverts per year.

For example, the annual effective dose corresponding to the values requested by EDF for renewal of the discharge and water intake licences for the Nogent-sur-Seine nuclear power plant was evaluated at 2.3 microsieverts per year. As the actual discharges from the Nogent-sur-Seine nuclear power plant in 2005 were lower than the specified discharge limits, the actual annual effective dose in 2005 is less than this value.
