SYSTEM INTEGRATION/ Atomic Energy 58 Information and analytical system to control the liquid radioactive waste treatment complex at Kola nuclear power plant By Vadim Krasnoslobodtsev, Mikhail Malinin, Gennadiy Gladyshev, Yurii Efimov, Nikolay Zhilenkov, Aleksei Nechaev, Vasiliy Tykshaev, Dmitriy Shvetsov, Victor Antufiev and Ruslan Petrov A unique project for the automation of the liquid radioactive waste treatment complex ( LRWTC) was implemented at the Kola NPP within the program of the international cooperation on nuclear safety. The state of the art treatment technologies which have no analogs in the world are designed to recover the liquid radioactive waste from the storage tanks and remove the radionuclides. In accordance with the adopted Federal Target Program, the development of the industry involves the distribution of the similar projects within the framework of international cooperation on increase in safety and reliable operation of the nuclear power plants. Due to the LRWTC, the Kola NPP will be able, within ten years, to fully get rid of the liquid radioactive waste accumulated from the beginning of the plant operation.
