DOPAS Project: Plug and Seal Demonstration for Geological Disposal Facilities

The DOPAS project, running from September 2012 to August 2016, aims to enhance knowledge on plugs and seals' feasibility in waste disposal. The project consortium, comprising 14 partners, focuses on plug design, characteristics measurement, and safety performance under repository conditions. Targeting various disposal concepts, DOPAS assesses tunnel plugs in clay and crystalline rocks and shaft seals in salt host rock. An international seminar with IGD-TP will be held in the project's final year. The research, funded by Euratom FP7, will establish reference designs and safety strategies for effective plug and seal implementation in geological repositories.

  1. FULL-SCALE DEMONSTRATION OF PLUGS AND SEALS DOPAS DOPAS will run in the period September 2012 – August 2016. An International seminar will be organized together with IGD-TP in the last year of the project. The DOPAS project is being carried out by a consortium of 14 partners representing waste management organizations, research institutes, academia & consulting companies. DOPAS aims to improve the knowledge regarding the industrial feasibility of plugs and seals, the measurement of their characteristics, the monitoring of their hydraulic and mecha-nical behavior under repository conditions, and their performance with respect to a range of safety objectives. DOPAS will identify the design basis of plugs and seals in geological disposal facilities, reference designs, and strategies to demonstrate the compliance of the reference designs to the design basis and to implement them into the experiments. DOPAS is focusing on tunnel plugs for clay host rock (French and Swiss disposal concepts), tunnel plugs for crystalline rock (Czech, Finnish and Swedish disposal concepts), and shaft seals for salt host rock (German disposal concept). The research leading to these results has received funding from the European Union's European Atomic Energy Community's (Euratom) Seventh Framework Programme FP7/2007-2013, under Grant Agreement No. 323273 for the DOPAS project.
