ASN Report 2017

354 ASN report on the state of nuclear safety and radiation protection in France in 2017 Chapter 12  - EDF Nuclear Power Plants 2.5 Prevention and management of environmental and health impacts 2.5.1 Monitoring of discharges and of waste management Monitoring the management of water intake and environmental discharges The Environment Code empowers ASN to define binding requirements concerning BNI water intake and discharges (see point 4.1 of chapter 4). The laws and regulations concerning environmental protection which apply to French NPPs comprise generic regulations, primarily the Environment Code, the Order of 7th February 2012 and ASN resolutions 2013-DC-0360 of 16th July 2013 concerning the management of detrimental effects and the health and environmental impact of BNIs, and 2017-DC-0588 of 6th April 2017 concerning procedures for water intake and consumption, effluents discharge and environmental monitoring for PWRs, as well as regulations specific to each of the NPPs: ཛྷ ཛྷ decisions setting the procedures for water intake and consumption and environmental discharges of liquid and gaseous effluents (chemical and radioactive); ཛྷ ཛྷ decisions setting the environmental discharge limits for liquid and gaseous effluents (chemical and radioactive); These decisions are approved by the Minister responsible for Nuclear Safety; ཛྷ ཛྷ the Orders of the Prefect authorising water intake and discharges of liquid and gaseous effluents: pre-dating November  2006, they contain binding requirements concerning the procedures and discharge limits specific to a nuclear site. In order to apply the new regulatory architecture to all the French NPP reactors, revision of the orders has led to them being repealed, with the adoption of ASN resolutions. For each site, ASN sets the limit values for emissions, water intake and discharge of effluents on the basis of the best GRAPH 1: Trend in the number of significant events rated on the INES scale in EDF nuclear power plants from 2008 to 2017 2013 2014 2017 2016 2015 2009 2008 2012 2011 2010 737 665 72 95 74 95 82 75 66 699 642 680 734 690 629 638 0 0 1 1 1 1 1 734 795 717 830 817 765 79 65 67 4 0 1 697 834 717 747 0 100 200 300 400 500 600 700 800 900 766 Total Level 0 Level 1 Level 2 GRAPH 2: Trend in the number of significant events per domain in EDF nuclear power plants from 2008 to 2017 2013 2014 2017 2016 2015 2009 2008 2012 2011 2010 628 109 96 90 114 120 116 91 699 622 639 689 640 586 583 112 86 93 93 115 100 100 712 122 130 109 98 77 79 0 100 200 300 400 500 600 700 800 688 Significant Safety Events Significant Radiation Protection Events Significant Environmental Events Events off the INES scale are also taken into account.
