Safe and Sustainable Back-End of the Fuel Cycle (SSFC 2020)

The second SSFC conference (SSFC 2020) will focus on research and development relating to the back-end of the nuclear fuel cycle and the disposal of radioactive waste in the Czech Republic. The conference will be held under the auspices of the Ministry of Industry and Trade and the Economic Committee of the Chamber of Deputies of the Czech Parliament. The event is being organised by the Czech Radioactive Waste Repository Authority (SÚRAO), whose mission is to ensure the safe disposal of radioactive waste generated in the Czech Republic and which is responsible for the coordination of a wide range of related research projects. International cooperation, which will receive particular attention at this year’s conference, makes up an integral part of the multidisciplinary research of issues surrounding the design and construction of deep geological repositories.


Tuesday 29 September – Wednesday 30 September 2020  

Hotel Pyramida, Bělohorská 24, Praha 6

Agenda will be announced soon 

Note: an optional visit to the Bukov Underground Re-search Facility will be arranged for those interested on Thursday

    URF Bukov

    The Bukov Uderground Research Facility is located at a depth of 550 metres below the earth’s surface, serves as a test site for the Radioactive Waste Repository Authority with respect to the assessment of the behaviour of the rock environment and building materials at a depth corresponding to that anticipated for the future deep geological repository for spent nuclear fuel and radioactive waste.
