Secondly, the research sector, which includes civil nuclear research, in particular the CEA’s laboratory and reactor research activities, but also other research organisations. Radioactive waste is produced during the operation, maintenance and decommissioning of these facilities. This radioactive waste is managed in accordance with specific provisions which take into account its radiological nature and are proportionate to the potential danger it represents. 1.1.2 Management of waste from small-scale nuclear activities governed by the Public Health Code The issues and challenges The use of unsealed sources(2) in nuclear medicine, biomedical or industrial research creates solid or liquid waste: small laboratory equipment items used to prepare sources, medical sources used to administer injections for diagnostic or therapeutic purposes, etc. Radioactive liquid effluents also come from source preparation as well as from patients who eliminate the administered radioactivity by natural routes. The diversity of waste from small-scale nuclear activities, the large number of establishments producing it and the radiation protection issues involved, have led the public authorities to regulate the management of the waste produced by these activities. Management of disused sealed sources considered as waste Sealed sources(3) are used for medical, industrial, research and veterinary applications (see chapters 7 and 8). Once they have been used, and if their suppliers do not envisage their reuse in any way, they are considered to be radioactive waste and must be managed as such. The management of sealed sources considered as waste, and their disposal in particular, must take into consideration both their concentrated activity and their potential attractiveness in the 1. Appendix 1 of the Order of 9 October 2008 amended relative to the nature of the information that the entities responsible for nuclear activities and the companies mentioned in Article L. 1333-10 of the Public Health Code are obliged to establish, keep up to date and periodically communicate to Andra. 2. Source for which the presentation and the normal conditions of use are unable to prevent all dispersion of the radioactive substance. 3. Source for which the structure or packaging prevents all dispersion of radioactive substances into the ambient environment, in normal use. 4. Circular of 25 July 2006 relative to classified installations – Acceptance of technologically enhanced or concentrated natural radioactivity in the waste disposal centres. 5. This name, which stands for “Centre industriel de regroupement, d'entreposage et de stockage” (Industrial centre for grouping, storage and disposal) was given in October 2012. When commissioned in 2003 it was called the “CSTFA – Centre de Stockage des déchets de très faible activité” (Very Low-Level Waste Disposal Facility). Installation subject to licensing under the system of section 2797 of the ICPEs. event of human intrusion after loss of the memory of a disposal facility at the end of its monitoring and surveillance phase after closure. These two factors therefore limit the types of sources that can be accepted in disposal facilities, especially surface facilities. 1.1.3 Management of waste containing natural radioactivity Some professional activities using raw materials which naturally contain radionuclides, but which are not used for their radioactive properties, may lead to an increase in specific activity in the products, residues or waste they produce. The term “Naturally Occurring Radioactive Material” (NORM) is used when the activity exceeds the exemption thresholds figuring in Table 1 of Appendix 13-8 of the Public Health Code (for example the treatment of rare earths, the production of phosphate fertilizers and phosphoric acid, the combustion of coal in thermal power plants, etc.). NORM waste, for which there is no planned or envisaged use, is therefore considered to be radioactive waste within the meaning of Article L. 542‑1‑1 of the Environment Code. Waste containing radioactive substances of natural origin but which do not exceed the abovementioned exemption thresholds is directed to conventional waste management routes. NORM waste can be stored in two types of facility depending on its specific activity: ∙ in a waste disposal facility authorised by Prefectural Order, if the acceptance conditions stipulated in the Circular of 25 July 2006(4) relative to waste disposal facilities, coming under sections 2760 of the ICPE classification are satisfied; ∙ in the Industrial centre for grouping, storage and disposal (Cires(5)) intended for the disposal of very low-level (VLL) radioactive waste. Some of this waste is however stored while waiting for a disposal route, in particular the commissioning of a disposal centre for low-level long-lived waste (LLW-LL).
