Facility Dossier Site-DE3

Official Designation: Nuklear Site-DE3

Site Identification Code: RAD-DE3

General information


Usage: Site-DE3 is an underground containment facility specializing in the isolation of radioactive hazardous materials and the development and improvement of radiation protection measures. This facility was also responsible for storing nuclear waste produced by the Foundation until 2018, along with nuclear waste from the Federal Republic of Germany.

Founded: 5. July 1968

Location: Wolfenbüttel, Lower Saxony

Cover: Asse II nuclear waste repository under demolition

Function: Containment and research of radioactive or radiation contaminated anomalies, development of new radiation protective equipment, and storage of nuclear waste from Foundation power generators (formerly).

Size: 21.000 m2 above ground, 34.000 m2 subterainian down to a depth of 960 m.

The above ground part of Site-DE3 is used for anomaly research, development of new radiation protection measures, and temporary containment of harmless anomalies recovered in the site's area of jurisdiction. Although the site has only an electric fence to defend against intruders, the buildings themselves are secured to the outside with at least 50 cm of reinforced concrete and 2 cm thick bulletproof glass. Presumably due to the anomalies stored here and the reputation of the site, Site-DE3 has so far the lowest recorded number of raids and infiltrations from outside of all Germanophone containment sites; the same applies to containment breaches.

Main Access: The main access to Site-DE3 is on Kuhlager Staße and is normally blocked by a metal gate. Persons wishing to enter the site must first report to the guard post, which is located in a cottage adjacent to the driveway leading to the entrance.

  • Staffing Guard Post: The driveway on the south side is manned around the clock by three guards, each equipped with an HK SFP9, pepper spray, taser pistols and telescopic baton. In addition, two HK MP5N submachine guns are available to each guard.
  • Side entrances: Possesses entrances to the west and to the east. While there is only a normal gate on the east, the entrance for the railway station is located on the west, which is blocked by an energized rolling gate, and in addition any enemy rail vehicles can be derailed by remote detonator explosives hidden under the tracks. The area is therefore patrolled and monitored by security personnel and RTF DE3-𝔊 (3-Gustav "Die Geiger", i.e. The Geiger). These are armed with HK MP5N submachine guns and an HK SFP9. In case of attack, HK433-12.5" assault rifles, M47 Dragon and Fliegerfaust 2 bazookas are also available.

Main Site: The main site includes the mine shaft access, administration building, research and testing facilities, train station, a helipad, personnel quarters, and barracks of RTF DE3-𝔊 and MTFs stationed here. In the event of an attack, it is also equipped with automatic gun turrets that can be extended from the ground. These are equipped with Heckler & Koch's HK GMW and distinguish allies from targets by their gait and body shape. They are controlled via administration quarters.

  • Administration: The administration is located in the center of the complex in a small house, which can be entered and also left in several ways.

Research and Testing facilities: The laboratories of site DE3 are designed for radiation experiments, but many other experiments can also be performed here to roughly gauge the properties of new anomalies. They are distributed over several buildings. In the underground floors, experiments are also carried out using a miniature particle accelerator. In addition to experimental rooms, there are also production rooms for radiation technology equipment and a TÜV station for such materials. These buildings also contain the temporary containment facilities for harmless anomalies and the infirmary, which is equipped with bunker walls and quarantine facilities for safety reasons. It specializes particularly in irradiation, in addition to normal injuries.

Barracks: The barracks have enough space to accommodate up to a hundred soldiers. In addition to standard small arms, underground garages also have a number of Survivor R armored vehicles on which various weapons can be mounted, along with standard stealth vehicles and transporters.

  • Staff quarters and offices: Site-DE3 personnel are housed in buildings protected from the outside by 1-meter-thick reinforced concrete walls. Likewise, in the event of a containment breach or attack, all windows and doors are sealed with armored steel bulkheads. Apart from the canteen, there are no recreational facilities here because of the space limitations and the close proximity to surrounding towns.

The underground portion of Site-DE3 is reserved for containment of its assigned anomalies and temporary storage of new and dangerous artifacts and entities. Because Site-DE3 is a former salt mine, the use of explosive weapons and large-caliber projectiles is prohibited underground due to the fragility of the walls and the risk of collapse. The lower levels have inherently passive protections in the form of strong radiation due to the anomalies stored within them, however all levels are equipped with automatic gas weapons and flame thrower systems in addition to safety bulkheads. The elevator that connects all levels is capable of carrying up to 15 tons of weight and can be buried in an emergency; likewise, all of the tunnels can be blown up in an emergency. All levels can be accessed by vehicles, as a salt mine does not require supports for its tunnels.

  • Floor U-1 Floor U-1 was dug after the Foundation acquisition and is located at a depth of 100 meters. It houses the nuclear reactor that supplies power to the site and the station for the underground maglev that connects Site-DE3 to Site-DE12, Site-DE13, Site-DE22 and Site-DE23. Access to the nuclear reactor is blocked by several security bulkheads that can only be opened with the biometric identification of approved technicians. Unauthorized access results in activation of the security system and release of toxic gas.
  • Floor U-2 Floor U-2 is located at a depth of 200 meters and, like U-1, was created by the Foundation. It is used for temporary containment of dangerous anomalies. By default, anomalies are not allowed to remain here for more than three months, otherwise Site-DE3 cannot meet its safety standards due to its requirements as a repository of hazardous radiation sources. However, the nature of Site-DE3 also aids in the containment of human anomalies, most of which willingly remain in their cells once it has been explained to them what Site-DE3's primary mission is.

Access to a laboratory area on U-3.

  • Floor U-3 Level U-3 extends over a depth of 500 m to 600 m and is used for the storage of safe-anomalies. In addition, experimental laboratories are located here for the study of anomalies that must be studied under special radiation protection conditions and for the testing of newly developed radiation protection measures.
  • Floor U-4 Level U-4 is located at a depth of 700 m to 800 m and is designed for containment of Euclid-class anomalies. Because of the radiation at this level, it is necessary to wear radiation protective suits with a closed oxygen supply here. Objects such as food for anomalies must also be transported in lead containers to prevent contamination. Containment cells, however, can be supplied with breathable air and clean water if necessary.
  • Floor U-5 Floor U-5 is located at a depth of 900 m to 960 m and is the most branched and extensive level of Site-DE3, which will be further developed with mining equipment if needed. Keter-class anomalies are stored here. The radiation levels here require additional protective measures, such as extra layers of lead on the protective suits. Normal people cannot survive without protection on this level, and the radiation also makes visual monitoring difficult, which is why additional vibration sensors have been installed throughout the level to detect unauthorized access and escapes.

Additional Information

As the Cold War progressed and nuclear technology advanced, the Foundation's Division in Germany had to take steps to manage an increased volume of anomalies that were radioactively contaminating their environment. Since transporting such anomalies to existing facilities specializing in radiation technology was very expensive and also risked causing disputes between the Foundation and various state governments, a containment site was sought within the Federal Republic of Germany. Given the geological conditions of the country, a salt dome was the safest option, so after evaluating several candidates, it was decided to use the Asse mine for this purpose. Negotiations with the German government under Ludwig Erhard finally achieved permission for the storage of radioactive hazardous materials, on the condition that the Foundation would also take over the disposal of the Federal Republic of Germany's nuclear waste in the process, but would be remunerated accordingly.

The site was formally established in 1968 and work began on reinforcing and expanding the surface structures. At the same time, the first low-level nuclear waste of the Federal Republic of Germany was discreetly stored, since there was still no guarantee of safety for stronger radiation sources. The extension of the existing tunnels was started in 1970. Regular operation began in 1972, but upgrading of the site was not fully completed until 1980.

In 1974, the Federal Republic of Germany defaulted on its payments, whereupon the Foundation's Division in Germany sent several reminder letters. However, the government under Brandt seemed intent on forcing the Foundation's Division in Germany to continue the agreement without payment, on the grounds that the federal government was allowing the Foundation to operate freely on its territory without compensation, which should suffice as payment. The Foundation then began lobbying and bribing decision makers to influence the Atomic Energy Act. This act was renewed in 1976 and its wording meant that the government failed to initiate a planning approval process for the Asse II mine and was thus forced to look for alternative disposal sites in 1977. The Foundation offered to continue to hold the federal government's nuclear waste for a fee until this process was completed. The government agreed. Since 1977, a large-scale campaign by the Foundation has now been underway to portray Site-DE3 as a nuclear waste repository in the process of demolition.

Since 201 █, Site-DE3 has been used to provide food for SCP-201-DE contained in Site-DE9, which feeds on radiation sources. However, this creature has a higher demand for nuclear waste than Site-DE3 receives, causing its supplies to run dry in 2018 and requiring new negotiations with the federal government to ensure a supply of nuclear waste.

As of 2019, Site-DE3 is no longer used as a nuclear waste repository and is used only for containment of radiated and radioactively contaminated anomalies and for radiation engineering research, as nuclear waste is now delivered to Site-DE9 to supply SCP-201-DE. However, space is still being reserved for final disposal in case either SCP-201-DE perishes or access to Site-DE9 is destroyed.
