Benchmark on reviewing approaches (WG#1)

Benchmarking on codes is quite common in the RWM field. Benchmarking on reviewing approaches is a new way to proceed. How will it work? By simulating interactions between regulatory body (RB), (prospective) waste management organisation (WMO) and Civil Society (CS), from the start to the end of a safety assessment review: a (part of) safety file is presented, clarifications and additional information are required through questionnaires and meetings, CS concerns are collected, recommendations are issued. The selected topic is an intrusion scenario caused by geothermal activities. Every player will have his place as TSO or CS, with or without code. This aims at learning from each other’s, testing the review guide and analysis grid developed previously by SITEX as well as identifying good practices.

State-of-knowledge related to deep borehole disposal (WG#2)

Many countries develop geological disposal facilities to dispose of high level waste. Some of them investigated deep borehole disposal as an alternative. What is this concept and what are the outcomes of these works? What’s about safety issues, societal concerns, economic matters? A bibliographic study will be made by both institutional and non-institutional SITEX.Network members, sharing the issues at stake. A practical synthesis will clarify what has to be known on that topic. In addition, a state of the art review on the different concepts of Deep Borehole Disposal (DBD) that were or still are investigated for high-level radioactive waste will be issued by SITEX.Network in 2020.
