In the Khlopin Radium Institute, during development of extractive partitioning of the liquid high level radioactive waste (HLW), a strip solution containing up to 6.0 × 1011 Bq/dm3 (16.3 Ci/dm3) of 137Cs in the form of a nitric acid solution was collected and temporary stored. To solidify this solution, a batch process using «Gubka» porous inorganic material (PIM) was developed and performed. Since that time, about 18 dm3 of HLW was solidified into 12 sets of «Gubka», reducing the liquid HLW volume by a factor of about 50. «Gubka» sets were placed into special containers, which were sent to the site of the RosRAO Branch in Sosnovy Bor after sealing by welding.
