Engineering and environmental studies of ground water radionuclide contamination

Engineering and environmental studies performed on section 3 of the former sludge collector at Kirovo-Chepetsk Chemical Plant, in particular of the actual radioactive waste layer, as well as of the underlying and adjacent rocks, have helped to identify the composition of radionuclides, along with their specific activity and filtration properties. Analysis of data describing the physical status of the sludge collector protecting dam leads to the conclusion that the structure still acts as a reliable engineering barrier. The radionuclide migration forecast have been made. The decommissioning project of sludge collector intends the arrangement upon its surface a clay screen approximately 1 m thick. Overlaying it will be soil layer with well-developed root system bushes planted
