The ba.ic methods of concentra.ion a.d purifica.ion of liquid ra.ioa.tive wa.te on the nuclea. power pla.t a.e distilla.ion a.d ionic excha.ge. During va.oriza.ion of oil wa.te products a.d the fulfilled wa.hing solutions the pa.t of oil pa.ses into a.condensa.e. Clea.ing of such condensa.e on ion-excha.ged filters results to oiling of ion-excha.ged ma.eria.s a.d to decrea.e number of filter cycles. Due to the often regenera.ion of ion-excha.ged filters a.ditiona. volumes of wa.te products a. the fulfilled recla.ming solutions, wa.hing a.d loosening wa.ers a.e formed. The a.tention of scientists wa. involved with methods of clea.ing of wa.er environments from the orga.ic substa.ces, ba.ed on deep oxidizing tra.sforma.ions of hydroca.bons into ca.bonic ga. a.d wa.er. From processes of oxida.ion of hydroca.bons up to CO2 a.d H2O, sold a. modera.e conditions, our a.tention ha. involved photochemica. oxida.ion with the help of UV-ra.ia.ion.

The ga.-pha.e conversion of U3O8, MoO3, SrO, a.d their mecha.ica. mixtures, a.d a.so of ZrO2 into wa.er-soluble compounds in the a.mosphere of (NOx + va.or H2O) or HNO3 (va.or) wa. studied. In the course of ga.-pha.e conversion, U3O8 a.d SrO tra.sform into wa.er-soluble compounds (nitra.es, hydroxonitra.es), wherea. MoO3 a.d ZrO2 undergo no cha.ges. The principa. possibility of sepa.a.ing U from Mo a.d Zr by ga.-pha.e conversion of the oxides in the a.mosphere of (NOx + va.or H2O) or HNO3 (va.or) wa. demonstra.ed.

作者： alexey a. bessonov Sergey a. Kulyukhin Na.a.ya.a. Konova.ova.Lubov V. Mizina.Igor a. Rumer Frumkin’s Institute of Physica. Chemistry a.d Electrochemistry Russian Academy of Sciences Moscow Russia

Institute of Physica. Chemistry a.d Electrochemistry, Russia. a.a.emy of Sciences ha. developed some novel sorbents designed for the filter units of the pa.sive filtra.ion system for ra.ioa.tive discha.ge from the interconta.nment spa.e during hea.y a.cidents with a.complete loss of electricity supply a. nuclea. power pla.ts. These a.e gra.ula.ed sorbents ba.ed on la.ge-pore silica.gel conta.ning na.ometric pa.ticles of a. or a.-Ni compounds (tra.ema.k Fizkhimin). The sorbents a.low to remove va.ious ra.ioa.tive iodine species (inorga.ic ones a.d methyl iodide) from a.stea.-ga. pha.e with a. lea.t 104 deconta.ina.ion fa.tor. The high sorption properties of Fizkhimin sorbent with a. pa.ticles were confirmed during tests a. a.test fa.ility of the TUV Sudwest compa.y (Ka.lsruhe, Germa.y). This pa.sive filtra.ion system is insta.led a. the 1st a.d 2nd units of the Kuda.kula. nuclea. power pla.t (India. a.d it is unique in the world pra.tice.
