NEOLANT in Lithuania Presented the Unique Experience in the World in the Field of Decommissioning of the Uranium-Graphite Reactors

22.07.2014

The group of companies NEOLANT, Digital Design and Engineering Center, presented the Russian experience gained in terms of engineering and information support at the decommissioning of nuclear and radiation facilities during The International Research and Practice Seminar entitled “Decommissioning of the uranium-graphite reactors” in Lithuania.

Lithuanian party shows great interest in scientific approach as well as applied technologies in the field of the decommissioning of nuclear and radiation facilities in view of shutdown Ignalina NPP. The said NPP has been built in 1983 in accordance with the Soviet project, so it is equipped with RBMK-1500 type reactors. The seminar was held on the territory of shutdown Ignalina NPP.

As the experts of NEOLANT have on-the-Russian Nuclear Complex long-term experience, they were invited by Ignalina NPP management in order to share their unique knowledge in the world and made two presentations:

  • The application of information models for engineering support of NPP decommissioning.
  • Engineering and Design for decommissioning, radioactive waste and spent nuclear fuel management.

“NPP Units Decommissioning Database” Information System developed by NEOLANT with no analog world-wide has been realized on the base of NPP engineering information models by order of Rosenergoatom (ROSATOM).

Moreover this technology enables to provide simulation modeling, for example development of dismantlement technology as one of the most important NPP decommissioning operation, because it is characterized by high complexity and high-level hazard. Also, NEOLANT specialists are able not only to model the processes in accordance with the ready developed techniques, but even to create own easy-to-perform technology with no extra cost (to stay in budget limits).

Currently, NEOLANT have already been successfully implemented “NPP Units Decommissioning Database” Information System on the six Russian nuclear power plants and are subject for further implementation on more four NPPs by the year 2020.

“The fact that we use the technology of information and simulation modeling as one of the NEOLANT’s key engineering skills, as well as we use the accumulated experience on how to support decommissioning process of Russian nuclear and radiation facilities allows us to offer our expertise nuclear companies abroad. Growing interest to our solutions on the part of foreign colleagues illustrates it in the best way”,–
said Vladimir Lyashchenko, Head of Project Chief Engineer Office of Design and Development Center, NEOLANT.
