4. RADIOWASTE PARTITION Problem Description & Market Need Efficient reprocessing of wastes arising from nuclear power remains one of the most complicated problems of radiochemical industry. Long-lived radionuclides, especially actinides, are the most hazardous components of the high level waste (HLW) of nuclear power stations. Their separation from the total waste mass and disposal should enable significantly to raise the ecological safety and efficiency of nuclear fuel cycle. A combined approach to HLW reprocessing, i.e. the recovery of several radionuclide groups immediately in one cycle, seems to be promising.

5. RADIOWASTE PARTITION RADIOWASTE PARTITION Brief technology description The HLW partitioning problem can be solved by the extraction technology with the use of organophosphorus extractants recovering TRU, technetium and platinides. The widely used extractants like trialkylphosphine oxide possess low efficiency and insufficient selectivity. We propose a new class of perspective extractants on the base of calixarenes functionalized with phosphine oxide, carbamoylphosphine oxide or diphosphine dioxide groups. In such compounds the binding groups may be best located around a metal cation, increasing the extraction efficiency and selectivity to a great extent. Extraction and stripping of radionuclides of the real High Level Waste

7. RADIOWASTE PARTITION RADIOWASTE PARTITION Advantages Calix[4]arene alkylphosphine oxides, carbamoylphosphine oxides or diphosphine dioxides extract simultaneously actinides, lanthanides, technetium and palladium from real HLW hundred times more efficient than the industrial extractants. In three contacts almoust 100% of gross - activity, more than 98 % of Tc and Pd were recovered from real HLW.

11. CHEMOSENSORS CHEMOSENSORS Problem Description & Market Need Calixarene based Electronic Nose was developed for monitoring of organic compounds in environment. Application of traditional methods for monitoring of hazardous substances in variable environment (air, water, waste, etc.) is not often effective and has a range of drawbacks, mainly complicity and long-term exposure. The main problem in developing of sensor systems is to supply them with the exceptional selectivity towards a different analytes.

12. CHEMOSENSORS CHEMOSENSORS Basic operation principles -Array of quartz crystal resonators are covered with calixarenecontaining receptors which have different sensitivity towards different volatile organic molecules. -Due to adsorption of analyte molecules onto sensitive surfaces of sensors frequency of quartz resonators is reducing. This frequency shift is considered as a sensor response. -Obtained array of sensors responses to pulse of analyte vapor is used for teaching system and after that – for recognition of chemical image of analyte by means of special mathematical apparatus for statistical treatment.
