Nuclear Physics and Engineering Publishes an Article on EKSORB's COREBRICK Technology

The article is called “Increase in the Efficiency of Localization of Cobalt-60 and Cesium-137 Radionuclides from Liquid Radioactive Waste for Ensuring the Radiation Safety of Nuclear Power Plants”. The article was authored by the representatives of three organizations: V. Remez and A. Ioshin (EKSORB Ltd), O. Tashlykov and S. Shchekleyin (Ural Federal University), and S. Kuznetsov (All-Russian Scientific Research Institute for Nuclear Power Plant Operation (VNIIAES)).

The article presents the sources of cobalt-60 in the technological scheme of a nuclear power plant and the methods to reduce its concentration in radioactive pollution. The contribution of radioactive cobalt isotopes to the formation of personnel dose load is assessed. The features and problems of cobalt removal from liquid radioactive waste are described. A scheme of ion-selective treatment using sorbents and a COREBRICK filter container is proposed, excluding the stage of destructing complex organic compounds of radionuclides. The necessity and possibility of optimizing (radiation protection of condensed radioactive waste) the composition of radiation-shielding materials of filter containers are considered. Experimental results of removal of cobalt and cesium radionuclides from liquid radioactive waste with the use of sorbents developed by Scientific Production Enterprise EKSORB are presented.
