In the fall of 2014, the Japanese government chose the Russian state corporation Rosatom as a partner for the implementation of a demonstration project to test the technology for treating radioactive water at the Fukushima-1 station. And a year and a half later, the leadership of Rosatom reported on the successful testing of a demonstration installation, with which Russian experts worked out the technology for purifying water from a dangerous radioactive isotope - tritium.
RIA Novosti was informed about the successful testing of the facility by Rosatom’s director for state policy in the field of radioactive waste, spent nuclear fuel and decommissioning of nuclear and radiation hazardous facilities Oleg Kryukov. After the accident in 2011, the Fukushima-1 station generated liquid radioactive waste in an amount exceeding one million cubic meters. The concentration of tritium in contaminated water exceeds the maximum permissible norms of WHO by 100 times. The Japanese have the technology to purify contaminated water from cesium and strontium isotopes, but they have no such technology for tritium.
Experts of the RosRAO company and the Khlopin Radium Institute, which are part of the Rosatom state corporation, worked on the implementation of the project for the purification of tritium water. The first tests of a demonstration installation for water purification created by Russian engineers were carried out at one of the RosRAO sites. According to the statements of Rosatom representatives, this is a unique installation, which differs from international designs in reduced energy consumption.
“The so-called model solution (simulating contaminated water at Fukushima-1) has been tested. We have achieved the result. The result is successful. We have achieved the necessary reduction, the frequency of water treatment, ”Kryukov said last Thursday in Murmansk at the regional public forum-dialogue“ Nuclear Energy and Arctic Development ”.
Kryukov also noted that at the site of the Fukushima-1 emergency station, in any case, a large scalable water treatment complex will have to be built, since without it it will be impossible to cope with the planned amount of work. What will happen next with the development of Russian scientists is up to the Japanese side. This decision is most likely to be made after Japanese experts familiarize themselves with the results of an experiment conducted by Russian colleagues.
