ENVIRONMENTAL AND SOCIETAL INFORMATION − HUMAN RESOURCES Reporting system and methodology

for waste not coming directly from fuel (control clusters, etc.) for which an ■ average life time of ten years is assumed: on the basis of feedback. oncerning EDF Energy The data relating to the indicator “Intermediate-Level radioactive Waste” of nuclear activities of EDF Energy, are founded on the inventory of radioactive waste produced during the year, established by the Nuclear Decommissioning Authority. This is an estimate of the annual volume of waste that will be considered and classified as Intermediate-Level radioactive Waste at the end-of-life of the nuclear generation sites. These estimates include packaging necessary to allow the transport of wastes off site. All of the Intermediate-Level radioactive Waste is temporarily stored at the nuclear generation sites while waiting for a national decision on their final processing. An update of the national inventory was performed in 2016 and the inventory was published on the official site of the “UK Radioactive Waste Inventory” (1) . “Low Level radioactive Waste” includes dessicants that are sent for processing in the form of Intermediate-Level Waste in compliance with applicable regulations. Further details on operational releases EDF operational releases into air and water in France are subject to ongoing measures. The data for EDF is calculated on the basis of: measured data for tritium, over the period from December N-1 to November N; ■ data measured in 2017 and calculated on the basis of generation of previous ■ years, for carbon 14, of January N to December N. The consolidation methodology takes account of the number of EDF reactors and SOCODEI operational units. Further details on the quantity of electricity and heat generated from renewable energies For Dalkia, the quantity of electricity and heat generated from renewable energies has been calculated on a pro rata basis to the quantities of renewable energies entering into their systems. Further details on the labour data 3.7.2.3 Since 2011, the population considered in data collection is all employees who have a non-suspended employment contract with one of the Group’s companies. Further details on calculating the workforce and movements For entities taken out of the scope of consolidation during the year under consideration: the indicators calculated in aggregate since the start of the year take into ■ account those entities for the period during which they belonged to the scope of consolidation; indicators measured at 31 December represent the situation at the end of the ■ year and do not take into account the entities which have left the scope of consolidation. The workforce includes employees shared between EDF and Engie. An employee working 50% for EDF is counted for 0.5 in the published workforce. The indicators “Other arrivals” and “Other departures” include: movements between companies of the Group; ■ movements of workers in the electricity and gas industry, in compliance with ■ industry-based agreement (IEG status); movements of certain categories of employees, in particular those with rotating ■ shifts, doctors and personnel made available by outside entities. These movements are thus not recognised in hires, resignations or redundancies. Further details on calculating absenteeism In its calculation of absenteeism, EDF includes absences for the following reasons: absences due to sickness, work and travel related injuries as well as absences due to other reasons such as unpaid leave and unjustified absences. Absences related to company and union activities, pre-retirement leave and maternity leave are not included. Absences related to company and union activities, pre-retirement leave

Further details on conventional waste The conventional waste data were obtained on the basis of data available on the closing date for the quantities removed and the disposal channels. It should be noted that the reported data is not comprehensive concerning conventional industrial waste from Tiru, Dalkia and EDF Énergies Nouvelles and from certain operational sites belonging to Edison (scope: Fenice), as this data cannot, at this stage, be reported within the Group’s reporting deadlines. Construction and decommissioning waste is included in this report, if its management falls under the responsibility of the EDF group. On the other hand, waste managed by service providers is not accounted for. Regarding Enedis, waste reporting is done on a rolling-year basis, from 1 November N-1 to 31 October N. Details on radioactive waste Concerning EDF Indicators pertaining to “Very Low Level radioactive Waste (VLLW) from operations and from decommissioning” take into account: the actual volume of the VLLW directly evacuated from the Industrial Gathering, ■ Storing, and Stockpiling Centre (Centre industriel de regroupement, d’entreposage et de stockage – CIRES) from the production sites, which corresponds: to the volume of waste produced in the year for operating sites; ■ to the volume of waste shipped in the year for sites being decommissioned; ■ the actual volume of VLLW waste packages sent to CIRES from Centraco (after ■ upgrading) connected to processing by incineration and by merging EDF metallic waste. The volume to be attributed to sites in operation and sites being decommissioned is determined in proportion to the tonnages delivered by the sites in operation and by the sites being decommissioned. Indicators pertaining to “Short Lived Low and Intermediate Level radioactive Waste (short lived LLW and ILW) from activity and from decommissioning” take the following into account: the actual volume of the short lived LLW and ILW waste directly evacuated into ■ the Aube Storage Centre (CSA) from the production sites, which corresponds: to the volume of waste produced in the year for operating sites; ■ to the volume of waste shipped in the year for sites being decommissioned; ■ the actual volume of LLW and ILW waste packages sent to the CSA from ■ Centraco (after upgrading) connected to treatment by incineration and by merging with EDF waste. The volume to be attributed to sites in operation and sites being decommissioned is determined in proportion to the tonnages delivered by the sites in operation and by the sites being decommissioned. Since 2016, the reduction in the volume contributed by treatment before storage (by ANDRA) has also applied to VLLW and also to packages sent by Centraco, where applicable. It includes the reduction in volume contributed by treatment before storage (the case of super-compacted waste). For the indicator “Long-Lived High- and Intermediate-Level solid radioactive Waste”, the packaging of the waste is taken into account in the calculation. Given the technical constraints linked to processing operations, the packages are produced approximately ten years after the fuel has effectively generated waste. The indicator is thus an estimate that relies on the long existence of current practices of packaging of Long-Lived waste that projects the current packaging ratio into the near future (number of packages effectively created following the processing of one tonne of fuel). This ratio essentially depends on the mixtures used to optimise the operations and is a combination: for waste coming directly from spent fuel: factors from the national inventory of ■ radioactive materials and waste created by the national Agency for the management of radioactive waste (ANDRA);
