Project summary

The objective is to conduct comprehensive research on the recovery of interim storage pond: used for radioactive waste, as pan of the restoration of the areas surrounding plants which were engaged in radiochetnical activities.

The are three stages to the project:

- preliminary research;

- laboratory research;

- accomplishing the scientific reports and desigen drawings.

The first stage, lasting nine months ,will entail a review of published information in order to see the current technologies and equipment. (Al) Concurrently, the project team will also investigate the composition of a storage pond at Siberian Integrated Chemical Works (SICW) (A2). This date will form the basis for the laboratory research. During the laboratory research, which is scheduled for the 7th through the 27th month, the project team will develop the processes and eguipment for:

- sludge removal;

- classifying and rinsing radioactive suspensions;

- sludge condensation;

- Ueaching long-lived radionuclides; and

- decontaminating waste solutions.

On the strength of these laboratory assessments, the team will elaborate engineering soecifications and drawines. This will occupy the 24th through the 36th months.
