Again changes in influent saline solutions detected in Asse
The inflow of saline solution into the Asse II mine has again changed. This time, a location in front of mining district 9 on the 750-m level is affected. A mining district is a mine opening where salt has been mined formerly. This mining district is backfilled with Sorel concrete, no radioactive waste is stored there. According to information provided by Asse GmbH, the volume of the influent saline solution has increased from previously 30 litres per day to now about 110 litres per day at the location in front of mining district 9. An increase in the saline solution volume does not have any safety-relevant effects on this level. What is noticeable is that a different chemical composition has been found in these new influent saline solutions. This indicates that the inflow occurs via a path that is different from previous ones. The influent saline solution has probably seeped through the Sorel concrete. Asse GmbH is observing the development. The Federal Office for Radiation Protection will continue to inform the public.
Three weeks ago, Asse GmbH had registered fluctuations in the inflow of saline solutions on the 658-m level. After some days, this inflow of saline solutions had again decreased to the former level of about 10.4 cubic metres per day. The total volume of influent saline solutions continues to range around 12 cubic metres per day.
