3 Presentation and organisation of the CIGEO project Surface installations ramp zone EDF archives "Ecothèque" Underground laboratory Service ramp entrance Technological Exhibition Facility Rail terminal Physical security-controlled area Service buildings (offices, car parks, refectory ) Industrial buildings (secure area, maintenance, utilities) 3 Campus Memory-keeping building Public information centre Security zone (monitoring, security, fire crews)

4 Presentation and organisation of the CIGEO project Surface installations shaft zone (scenario 2) Construction site zone Physical security-controlled area 4 Service buildings (offices, car parks, refectory ) Industrial buildings (secure area, shaft, works zone, maintenance, utilities) Security zone (monitoring, security, fire crews)

5 Presentation and organisation of the CIGEO project Overall progress of the CIGEO project An atypical nuclear installation, built and operated underground over a period of more than a hundred years. Development of the structures in stages, to be operated successively, with a flexible approach. CIGEO at completion SCOPE OF THE MANAGEMENT PLAN DESIGN PHASE COMPREHENSIVE DESIGN CIGEO PHASE 1 DESIGN CONSTRUCTION OPERATION CIGEO PHASE 2 DESIGN CONSTRUCTION OPERATION 5

8 Developments around the sites (outside Andra project ownership) Scenarios and zones for water supply and discharge Requirements in late 2018 Water requirements 2019 to m 3 /day from m 3 /day Water Electricity Natural gas Roads Rail network CIGEO Geological Disposal Facility Drinking water abstraction with authorised daily extraction in m 3 "SDAGE" abstractions "Grenelle" abstractions kilometres Water supply zone to be studied 8 Car n9_water supply,wor 31/10/2012 Discharge Fuseau des zone rejets

9 Developments around the sites (outside Andra project ownership) Delivery station connection study Path studied by the grid operator for detailed study Lambert 93 projection Scale: Requirements in late 2018 Scenario 1 Scenario 2 Scenario 3 Water Electricity Natural gas Roads Rail network Note: The locations shown on this map have been given by the grid operator to give an idea prior to the detailed study. The definitive locations will be specified after the public debate. Scenarios 1, 2 and 3 EDF Archives "Ecothèque" Underground laboratory KEY Existing installations Underground EDF archives laboratory centre Technological "Ecothèque" Exhibition Facility HVB power line (grid operator) (50m exclusion zone either side of the HV line) Possible locations for CIGEO delivery stations Possible location for grid operator substation Possible locations for nearby surface installations: Ramp Shafts entrances Proposed locations: Scenarios Scenario for ramp for 1,2 and 3 No. entrances shafts Technological Exhibition Facility Preferred location Variant Possible connection (grid operator) (Zone approximately 150m from each side) Zone specified for underground installations Département boundary 9 New 400/90 kv substation (grid operator) or 2 new 90 kv delivery stations (1 in ramp zone, 1 in shaft zone) 2 new 90 kv buried lines providing loop redundancy between the delivery stations

10 Developments around the sites (outside Andra project ownership) Alternative resource being studied for heating, drying, steam and hot water production, etc. No distribution network in the Bure-Saudron area Water Solution involves connecting to networks approximately 20 km from CIGEO Electricity Natural gas Roads Rail network Network construction Delivery station 10

11 Developments around the sites (outside Andra project ownership) Requirements in 2017 Rerouting of the RD 960 Water Electricity Natural gas Roads Road section retained within the Ramp zone Link to the shaft zone Rail network Graphical scale: 11

12 Developments around the sites (outside Andra project ownership) Water Electricity Natural gas Roads Rail network Nançoissur-Ornain Hypothetical rail terminal connected to the rail network Restructuring the existing line between Nançois-sur-Ornain and Gondrecourt-le- Château 12 Gondrecourt-le- Château

13 Preliminary site developments (under Andra project ownership) Preliminary developments General earthworks, fencing, 90/20kV substations, Start of work dependent on adminstrative turnaround times and procedures Rail link and terminal Rail link Ramp zone Creation of a new line from Gondrecourt-le-Château to enable transport and reception of: waste packages from production sites, heavy goods and equipment required for CIGEO construction from supplier sites. Rail terminal Fencing and earthworks Site installations Tunnelingmachine assembly rooms Hypothetical rail terminal connected to rail network Gondrecourtle-Château Shaft zone Fencing and earthworks Site installations Rail terminal Distance along the line between the two circles: 14 km 13
