To be able to retrieve the radioactive wastes from the Asse II mine, uncertainties and gaps in knowledge need to be eliminated for reliable planning. That is the only way to concretely approach the technical implementation.
Fact-finding: Creation of a data basis
The fact-finding began in 2012 by drilling measures carried out in the vicinity of emplacement chamber 7 in a depth of 750 metres. The plan was to collect the first data – for example about the state of the surrounding salt rock, the state of the waste packages, the radioactive contamination of the air inside the chamber and the emplacement chambers' stability.
Modified legal conditions
Experiences gained so far in the exploration and the time lapses in the licensing procedures have shown that these are not in conformity with the objective of retrieving the waste as soon as possible. Furthermore, the legal situation has changed since the fact-finding began. The "Lex Asse", which became effective in 2013, provides new legal options. For example, the necessary basic radiation protection considerations were already taken into account in the development of the law. Previously, the Federal Environment Ministry followed the legal position effective in 2010 and determined that a fact-finding take place before retrieval operations could start. Two chambers were to be examined on a trial basis to check the feasibility of retrieval. With the "Lex Asse" coming into force, a justification relating to single measures or decommissioning variants is no longer required.
Strategy paper evaluating the fact-finding
The BfS takes account of these modifications by basically examining and as far as possible improving the procedures. A working group established by the BfS president and consisting of experts from the BfS and the Asse-GmbH, has therefore developed a strategy paper on how to optimise the exploration programme dealing with the emplacement chambers, in order to improve the retrieval processes. The paper with the title "Evaluation of the fact-finding and the retrieval procedure" was introduced to the public on 15 April 2015.
