Construction of a surface respository in the Ukraine case study


Courtesy of NAUE GmbH & Co.KG

As part of the shutting down of the nuclear power station in Chernobyl, a surface respository for weak to medium radio-active waste is being constructed around 30 km away from the power plant premises. The total building project JCSRM-Industrial Complexe for Solid Rodwaster Management) is sponsored by the EU and RWE Nukem GmbH, general contractors for these measures, commissioned NAUE GmbH & Co. KG with the planning of the sealing system for the base plate of the repository. The system put forward by NAUE was thoroughly reviewed and then approved by the Ukrainian authorities and supervisory bodies responsible. The sealing work was carried out by the Bueckeburg subsidiary NAUE Sealing between September and October 2005.

The sealing system comprised the following components, from top to bottom:

  • Concrete sub-base course
  • Secutex® R 404 protective nonwoven
  • Carbofol® HDPE 2.0 mm smooth sealing
  • Secudrain® XX8 control layer
  • Secutex® R 404 protective nonwoven
  • 0.30 m non-reinforced concrete layer
  • 0.70 m reinforced concrete layer

To drain off the individual storage boxes, the sealing was linked up to a pre-fabricated drainage system which carries the drainage water via a collective line to the downstream treatment plants. To ensure the required quality during the construction phase, installation was permanently monitored by us, and additionally by the owner. This sealing system using NAUE geosynthetics thus meets all the requirements (from raw materials to completed installation) of both the owner and those made by the EU regarding ground water protection systems.
