Indicators on cooling water include water withdrawn and water returned to rivers, the sea and water tables. For nuclear power electricity plants located on coastlines and for thermal power plants, the amounts of cooling water withdrawn and water returned are calculated on the basis of the operating time and nominal debit of pumps.
This indicator does not include data for the MECO company, as water consumption is negligible (open cooling circuit). Furthermore, these indicators are not collected for the Edison operating centres managed by Fenice.
Air emissions from thermal power plants of the EDF group are measured or calculated on the basis of analyses of the fuels or based on standard emissions factors. The Group’s SF6 emissions are calculated, as a matter of priority, on the basis of a mass balance or, to a lesser extent, using an estimation method approved by Executive Management at the entity in question (for example, application of a leakage rate). Emissions from certain power plants are not material for the Group and as such are not reported. This is the case for dust emissions from CCGT power plants (excluding EDF), N20 and SF6 emissions from MECO’s CCGT power plant, and emissions from Dalkia Barkantine’s power plant in the United Kingdom. The indicator’s scope covers the Group.
Indicators pertaining to “short-lived Very Low Level radioactive Waste (VLLW) from operations and from decommissioning” take into account the actual volume of the short-lived 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:
Indicators pertaining to “Short Lived Low and Intermediate Level radioactive Waste (short lived LLW and ILW) from activity and from decommissioning” take into account the actual volume of the short-lived LLW and ILW waste directly evacuated to the Aube Storage Centre (CSA) from the production sites.
In each case, those volume correspond:
Since 2016, the reduction in the volume contributed by treatment before storage (by ANDRA) has applied to short-lived VLLW and to packages sent by Centraco, where applicable. It includes the reduction in volume resulting from treatment before storage (the case of super-compacted waste).
For the indicator “Long-Lived High- and Intermediate-Level solid radioactive Waste” (HILW-LL), 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:
Radioactive waste data from Framatome in France is similar to EDF’s dismantling waste and so can be consolidated. Internationally, Class A waste (USA and Belgium), comparable to very low level waste (Germany), are not consolidated. Radioactive waste is shipped and handled in accordance with domestic regulations in force in each country.
The data relating to the indicator “Intermediate-Level radioactive Waste” of nuclear activities of EDF in the UK, 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 2019 and the inventory was published on the official site of the “UK Radioactive Waste Inventory”. “Low Level radioactive Waste” includes desiccants that are sent for processing in the form of Intermediate-Level Waste in compliance with applicable regulations.
The indicator concerns solid waste from the active nuclear generating fleet. In France, the indicator covers long-lived high- and intermediate-level waste. In the UK, the indicator covers low-level waste (only category of radioactive waste transported off generation sites). The scope covers the Group where radioactive waste-related activities concern: EDF and EDF in the UK.
The indicator concerns the number of level-2 major events on the INES (International Nuclear Event Scale). The indicator’s scope covers the Group.
The indicator takes account of the number of fatal accidents linked to business risks occurring in the year. The indicator’s scope covers the Group.
Fatal accidents involving employees linked to business risks correspond to fatal accidents of employees at work, employees of the Company, including work-study students and apprentices. Fatal malaises are excluded from this scope. Employee transit accidents while on work-related business are taken into account, excluding those occurring in transit between home and work.
Fatal accidents involving service providers linked to business risks include fatal accidents involving service providers that occurred during the course of work performed on behalf of the Company regardless of the level of subcontracting. Fatal malaises are excluded from this scope. Traffic accidents on duty and commuting accidents between home and the usual place of work are not included in the published figure taken into account.
The indicator is calculated by finding the ratio of the number of employees having benefited from a skills development action to the actual workforce at the end of the period. Skills development actions include training courses, hours spent in school by people on professionalisation contracts and professionalisation actions. The employees counted are those (including professionalisation contracts) who are present or not in the workforce at the end of the period and who have participated in at least one skills development action during the year.
Professionalisation actions are intended to transform theoretical skills and knowledge taught mainly in training into practical skills, anchored by their implementation in work situations. They have been formally integrated into the definition of the indicator for 2021. The trainings for which supporting documentation is not received on the date of closure of the reporting and professionalisation actions which are not registered with a supporting document are not taken into account. All professionalisation initiatives are recorded in the MyHR Group tool, which will make it easier to monitor them. The indicator’s scope covers the Group.
