ڲ٫ת The principles of nuclear safety and radiation protection ׏ِ׏ IɖȇƳƏȅƺȇɎƏǼ ȵȸǣȇƬǣȵǼƺɀ Nuclear activities must be carried out in compliance with the principles that underlie the legislative texts. This primarily concerns: Ҋ at the national level, the principles enshrined in the Environment Charter, which has the same value as the Constitution, and in the various codes (Environment Code, Labour Code and Public Health Code); Ҋ at the European level, rules defined by Directives establishing a community framework for the safety of nuclear facilities and for the responsible and safe management of spent fuel and radioactive waste; Ҋ at an international level, ten fundamental safety principles defined by IAEA (see box below and chapter 6, point 3.1) implemented by the Convention on Nuclear Safety (see ĶĻĴŃŇĸŅׇӉ ŃłļŁŇ Ӈєӄҏё ĸņŇĴĵĿļņĻļŁĺ ŇĻĸ ļŁŇĸŅŁĴŇļłŁĴĿ ĹŅĴŀĸŊłŅľ for the oversight of nuclear safety and radiation protection. These various measures of differing origins extensively overlap. They can be grouped into the eight main principles presented below. ׏ِ׏ِ׏ ¨ȸǣȇƬǣȵǼƺ Ȓǔ ǼǣƬƺȇɀƺƺ ȸƺɀȵȒȇɀǣƫǣǼǣɎɵ Ļļņ ŃŅļŁĶļŃĿĸё ķĸĹļŁĸķ ļŁ ŅŇļĶĿĸ ӌׇłĹ ŇĻĸ łŁʼnĸŁŇļłŁ łŁ ňĶĿĸĴŅ Safety, is the first of IAEA’s fundamental safety principles. It stipulates that responsibility for the safety of nuclear activities entailing risks lies with those who undertake or perform them. It applies directly to all nuclear activities. ׏ِ׏ِ ٹ א ¨ȒǼǼɖɎƺȸ ٮ ȵƏɵɀ ٺ ȵȸǣȇƬǣȵǼƺ Ļĸ ѢŃłĿĿňŇĸŅ ŃĴŌņѣ ŃŅļŁĶļŃĿĸё ĶłŁŇĴļŁĸķ ļŁ ŅŇļĶĿĸ ӄӄӃіӄׇłĹ ŇĻĸ Environment Code, stipulates that the costs resulting from the measures to prevent, mitigate and fight against pollution must be borne by the polluter. ׏ِ׏ِ ב ¨ȸƺƬƏɖɎǣȒȇƏȸɵ ȵȸǣȇƬǣȵǼƺ Ļĸ ŃŅĸĶĴňŇļłŁĴŅŌ ŃŅļŁĶļŃĿĸё ķĸĹļŁĸķ ļŁ ŅŇļĶĿĸ ӈׇłĹ ŇĻĸ Environment Charter, states that: “ the absence of certainty, in the light of current scientific and technical knowledge, must not delay the adoption of effective and proportionate measures to prevent a risk of serious and irreversible damage to the environment ”. CHAPTER 02 Nuclear security is defined in the Environment Code as comprising “ nuclear safety, radiation protection, prevention and combating of malicious acts and civil protection actions in the event of an accident ”. Nuclear safety is “ the set of technical provisions and organisational measures –related to the design, construction, operation, shutdown and decommissioning of Basic Nuclear Installations (BNIs), as well as the transport Ȓǔ ڳ ȸƏƳǣȒƏƬɎǣɮƺ ɀɖƫɀɎƏȇƬƺɀ چ ɯǝǣƬǝ Əȸƺ ƏƳȒȵɎƺƳ with a view to preventing accidents or limiting their effects ”. Radiation protection is defined as “ protection against ionising radiation, that is the set of rules, procedures and means of prevention and surveillance aimed at preventing or mitigating the direct or indirect harmful effects of ionising radiation on individuals, including in situations of environmental contamination ”. Nuclear safety and radiation protection obey principles and approaches that have been put in place progressively and continually enhanced by a process of feedback. The basic guiding principles are advocated internationally by the International Atomic Energy Agency (IAEA). In France, they are included in the Constitution or enacted in law, as well as now figuring in European Directives. In France, the regulation of nuclear safety and radiation protection for civil nuclear activities is carried out by the French Nuclear Safety Authority, ASN, an independent administrative Authority, in liaison with Parliament and other State stakeholders, within the Government and the offices of the Prefects. This regulation, which covers related areas such as chronic pollution of all types emitted by certain nuclear activities, is based on technical analysis and expert assessment, particularly that provided by the Institute for Radiation Protection and Nuclear Safety (IRSN). At the State level, the prevention of and fight against malicious acts which could affect nuclear materials, their installations and their transportation are the responsibility of the Minister for Ecological and Solidarity-based Transition, who can draw on the services Ȓǔ ژ Ɏǝƺ RǣǕǝ…ǔǔǣƬǣƏǼ ǔȒȸ (ƺǔƺȇƬƺ ƏȇƳ ³ƺƬɖȸǣɎɵ (HFDS).
