WANO technical support mission "Radioactively contaminated water management" is taking place at Chernobyl Nuclear Power Plant from May 15 to May 19.
Within the mission experts from Ukraine, Hungary and Russia together with Chernobyl Nuclear Power Plant’s specialists discussed the problem of Radioactively contaminated water management at Chernobyl Nuclear Power Plant and visited Radioactive Waste Management Facilities, currently existing at ChNPP.
At Chernobyl NPP the volume of accumulated waste water in the special sewage system makes approximately 12.000 m3/year. At the moment at Chernobyl NPP a scheme for the radioactive waters purification is in operation, which is intended for the operational condition of the unit. The current use of resources (gas, heat, electricity and steam) for the radioactive water purification and the purified water production is inefficient and expensive.
Among the major practical tasks of the mission is search of optimal and economically expedient approach to the waste water treatment at Chernobyl NPP, as well as identification of optimal technology for their treatment with minimum secondary waste generation and reasonable economic efficiency in decommissioning conditions.
During the mission Chernobyl NPP specialists were acquainted with modern approaches and methods for the radioactively contaminated water (RCW) treatment and with experience of their utilization at RAW Management facilities (NPPs).
It should be noted that Chernobyl NPP is dealing with water purification gradually and systematically. So, in accordance with ChNPP request the Moscow WANO Center in October 6-8, 2014 held the technical support mission "Identification and introduction of new methods for the equipment decontamination. New methods and technologies for the radioactive water purification". In August 2016 at the request of ChNPP IAEA held the workshop to select the technologies for salt water purification (radioactive waste water treatment). Under support of the European Union the project aimed on designing of the facility for the Shelter object water and liquid radioactive waste purification from TUE and organic compounds is underway.
All these activities are aimed at finding of optimal and economically expedient approaches to radioactively contaminated water management at Chernobyl NPP.
