Radioactively contaminated brine accumulated over years in front of an emplacement chamber in the Asse mine the handling of which had not been clear is now being removed and processed further. The Federal Office for Radiation Protection (BfS) has initially pumped out altogether around 17 cubic metres of brine in front of chamber 12 on the 750-m level of the Asse mine and has the brine taken to special collecting containers in another part of the mine. The brine is to be further processed to salt concrete in the mine. The removal of the brine enables the next step in the retrieval of the waste from the Asse mine. Besides it makes emergency preparedness easier.
Law governing the Asse mine (Lex Asse) is to speed up retrieval
Strong political support for an important step: The so-called Lex Asse creates legal provisions to speed up the retrieval of the nuclear waste from the Asse II mine. In the new Asse law, retrieval will now also be legally laid down as the decommissioning option to be pursued. The key points of the new law are explained in the 20th edition of the “Insights into the Asse Mine”.
For as long as the Asse II mine is being operated actively, emergency preparedness (precautions and emergency measures) is required to ensure the protection of man and environment. This is a result of the expert workshop “Radiation Protection and Emergency Preparedness” that was organised by the Federal Office for Radiation Protection (BfS) on 20 and 21 November 2012 in Wolfenbüttel. 130 Asse experts from all over Germany had a vivid and constructive debate which was also controversial at times. Apart from the Federal Environment Ministry (BMU), the Lower Saxon Environment Ministry (NMU), the Asse-2 Accompanying Group and the Asse-GmbH, planners and experts attended the workshop..
The 19th edition of “Insights into the Asse Mine” presents possible solutions for the handling of the inflowing saline solutions and brines of the Asse mine. There is a graph showing what types of saline solutions exist in the mine, how they can be handled and what problems occur in terms of their disposal. Further topics are the parliamentary Committee of Inquiry dealing with Asse (PUA) whose work concluded at the end of October and the issue of safety for future generations (long-term safety).
