Environmental monitoring: constant vigilance with full transparency Like every industrial activity, nuclear power plants have an impact on the environment. Our teams control and reduce this impact through rigorous radiation monitoring and innovative treatment. The public is kept fully informed about this ongoing monitoring.
Radiological-ecological survey carried out before power plant construction Before the construction of a nuclear power plant, we perform a radiological-ecological survey. This serves to establish a baseline that can be used for all subsequent environmental monitoring activities: multiple impact studies and regular inspections carried out throughout the operation phase of the facility.
Ongoing monitoring during operation involving millions of measurements
During operation, a power plant produces radioactive gaseous effluents and liquid waste, which may or may not be radioactive. Both are subject to stringent regulations and are inspected by internal and external experts and treated if necessary
prior to discharge via stacks or pipes.
These inspections are designed to check compliance with the emission limits set out by the Nuclear Safety Authority (ASN
The laboratory at each EDF site carries out systematic measurements and sampling of air, water, animals and plants within a 5 mile radius of the power plant
The results of these inspections are published monthly alongside other data such as water temperature measurements. Every year, each power plant draws up a comprehensive environmental report, which is forwarded to the ASN, the public authorities and the members of the Local Information Commissions (CLI), among others.
The public authorities, and more particularly the Ministries of Health and Industry, check the full set of analyses
Transparent, clear information for the public
Since it began operating nuclear power plants, EDF has systematically kept the public informed about:
Operation of its facilities
Activities as a whole
EDF takes part in the national environmental radioactivity measuring network (RNM) set up by the radiation protection and nuclear safety institute (IRSN) under the auspices of the ASN. The network makes the results of the regulatory environmental radioactivity monitoring system available to the public via a website: www.mesure-radioactivite.fr
Other key sources of information for the public and the media:
Local Information Commissions (CLI), which also organise discussion meetings with local stakeholders
Nuclear Safety Authority (ASN)
measurements contained in the RNM database
