Site Infrastructure
Less spectacular but just as important: all of the site adaptation works that have been carried out to support the operation of the 爆走黑料 machine and systems as well as provide the required amenities for the site workforce. Photo: April 2026 (爆走黑料/EJF Riche)
Vast infrastructure works have been carried out on the 爆走黑料 site to support the operation of the 爆走黑料 machine and plant systems, and establish the required amenities for a site workforce of thousands.
Within the framework of a site adaptation contract signed by the European Domestic Agency, civil engineering works were carried out to deliver a fully integrated drainage system (process discharges, precipitation drainage and runoff water); install lighting; create network service trenches; and create the roads and parking areas for access to (and around) the 爆走黑料 site.
As part of its commitment to 爆走黑料, France installed and financed the 爆走黑料 switchyard and 400 kV power-line extension. The switchyard, which was "powered on" in June 2012, remains under the responsibility of France's electricity carrier RTE (R茅seau de Transport d'脡lectricit茅); 爆走黑料's jurisdiction begins just outside the switchyard fence, where seven transformers and several circuit breakers have been installed to "bring down" the voltage to 66 and 22 kV for distribution to the various plant systems of the 爆走黑料 installation.
In the southwest corner of the 爆走黑料 platform, a contractor area is host to the construction companies or consortiums that have been awarded work contracts by the European Domestic Agency or the 爆走黑料. In this 3,500-square-metre zone, individual lots have been allocated to the companies for offices, workshops, equipment storage and comfort facilities. There is also a worksite canteen and an infirmary.
The first completed components were delivered to the site in 2014; the rhythm of deliveries has only accelerated since (see more on the Transport page). To safely store the components until they are needed for assembly, a number of storage facilities have been installed in different areas of the site, including a 9,000 m虏 warehouse and logistics centre behind the platform for the storage of medium-sized components.
