Public inquiry related to the authorisation request for the substantial modification of the basic nuclear installation (INB) Nr. 115, named 'Reactor nr. 4 of the Paluel electricity production nuclear centre (CNPE)', in order to authorise the introduction of MOX precursors, project submitted by Electricite de France (EDF) - Report of the inquiry commission + Motivated conclusions and opinion of the inquiry commission

A first document reports the opinion of the French Environmental Authority (Ae) about a project of modification of one of the Paluel nuclear reactors. It first presents the Paluel electric power production nuclear centre (CNPE), its operation and emissions (radionuclides, liquids, chemical atmospheric effluents), procedures related to the project, and the main environmental stakes noticed by the Ae. It comments the various aspects of the project impact study: radiological pollution, waters, aquatic and marine environments, air and atmospheric pollutions, waste production, population and human health, natural and technological risks, energy, climate change mitigation, project vulnerability. It comments the evolutions of impacts with the introduction of MOX in the reactor nr. 4. It briefly discusses the content of the non-technical summary, and finally comments how hazards and population safety are addressed. The second document is the report of the inquiry commission about the public inquiry associated with this project. It presents the public inquiry framework, the project as it was submitted to the public inquiry (location, reactor operation, the Paluel centre, the 'moxing' project), describes the content of the file submitted to public inquiry, and the inquiry organisation and process, and proposes an analysis of contributions produced during the inquiry
