Konrad shaft: repository companies check their own plans

Three repository companies involved in the planning and construction of the Konrad mine shaft also weighed in heavily on a safety assessment. This is what our newspaper learned. This is not just any report, but a review of the safety requirements for the Konrad repository, or usiko for short.

The report, presented earlier this year, became necessary because the zoning decision dates from 2002, basic plans even date from the 1980s, and the final repository in Salzgitter is not scheduled to go into operation until 2027. usiko is to ensure that the planned repository always remains at the cutting edge of science and technology.

The companies involved are DMT GmbH from Essen, Brenk Systemplanung GmbH from Aachen and the Gesellschaft fur Anlagen und Reaktorsicherheit (GRS) from Cologne. There were other companies involved in usiko, as well as a so-called review team consisting of four researchers. One of them is Professor Klaus-Jurgen Rohlig from the Clausthal University of Technology. Rohlig worked for GRS in Cologne from 1991 to 2007. The review team's verdict on Konrad safety: there is "no evidence of aspects with respect to which the safety assessment should be fundamentally questioned".

These statements are now in a different light, say the nuclear expert of the Left Party parliamentary group in the Bundestag, Hubertus Zdebel, and Ursula Schonberger of AG Schacht Konrad. The two recognize a conflict of interest. "It is clear that this cannot be an independent expert opinion," Schonberger said. Zdebel detects a "taint". After all, it is about further orders. The Konrad operator, the Bundesgesellschaft fur Endlagerung, points out that public tenders were ied.
