Project summary

Disposal of radwastes accumulated in the world is an urgent problem requiring immediate solution, as at present great amounts of radwastes have been accumulated. Liquid radwastes are the significant part of radwastes. It’s well-known that according to IAEA requirements the burial of liquid radwastes is prohibited. Disposal of liquid radwastes is carried out using the following methods: grouting, lime pretreatment, etc. Up to the present time low-active wastes have been discharged into the sea, liquid radwastes have also been pumped into depths of the earth. This results in accumulation of large amounts of production waste deposits and it will take millions of years for nature to decontaminate the wastes. Technological disposal of radwastes will solve this problem.

Uranium containing waste purification by means of reagents is presented in the given Project. Uranium containing waste water is considered to be the most dangerous for environment because it’s characterized by high toxicity, complex and variable composition, organic and non-organic contamination in solute and suspension state. It’s very difficult to select reagents and methods that enable to perform deep purification of waste waters having such perse composition.

Method of using cation flocculants is one of the most effective for uranium containing waste water purification. There is no very wide range of cation flocculants produced by Russian industry. Moreover, such a narrow range of produced flocculants doesn’t take into account specific character of uranium containing waste water purification.

Thus, the development of an effective cation flocculant for uranium containing waste water purification is an urgent problem.

Preliminary studies of waste water purification using cation flocculants have been performed by authors’ group and satisfactory results have been obtained.

The goal of the proposed Project is to produce an effective flocculant and to develop fundamentals of uranium containing waste water purification technology.

In the process of the proposed Project performance it’s planned to solve the following tasks:

1. Develop a modified cation flocculant (based on commercially produced cation flocculant) conforming to specific requirements of effective uranium containing waste water purification.

2. Carry out studies of fundamentals development of uranium containing waste water purification technology using the produced cation flocculants.

3. Develop technology and set up the flocculant production for internal needs of the enterprise.

Implementation of the given Project makes it possible to decrease water consumption, partially to solve the problem of discharging the wastes non-hazardous to environment, to reorient the scientific and technical personnel specialized in the field of radioactive materials reprocessing to peaceful production, to ensure employment of high-qualified specialists (that can lose their work because of reduction of main stream production volume) in the field of solving the environment protection tasks, as well as to favour the conversion of enterprises of defense complex to market economy meeting civil needs.

Funding of the present Project will provide for the support of the applied R&D works for peaceful purposes.

Potential role of foreign collaborators:

Contacts with foreign firms are suggested to be established with the aim of mutual consultations, visits, joint patenting and chemicals production for uranium containing waste water purification.
