Software and technical complex for safety substantiation of nuclear legacy facilities
Problems of determination of the fate of nuclear legacy objects, including, in particular, the options of decommissioning these objects on the basis of detailed substantiation of relevant projects are becoming extremely important in the nearest future. No practices of wide scope solution of such problems have so far been developed in Russia and the first steps in this direction were made within the framework of implementation of the Federal Target Program «Nuclear and radiation safety assurance in 2008 and for the period until 2015». The issues emerging in the substantiation of projects of decommissioning such objects as pertains to the assessment of radiation protection and safety both for public and for personnel significantly differ from those addressed in designing new objects of nuclear technology. This is explained by the critical shortage of information both about the nuclear legacy objects per se, and, as well, about radioactive wastes disposed inside them. Additional difficulties arise because since the time when these objects were created regulatory requirements imposed on objects of such types underwent significant changes. Therefore, development of approaches to the substantiation of nuclear, radiation and environmental safety of such objects represent extremely important problem. OBOYAN software and technical complex combining software and hardware tools and ensuring implementation of analysis and substantiation of safety of NHOs in their current conditions and in long-term perspective was developed in order to solve numerous problems emerging within the framework of this general task. The main components of the complex are the computational modules for simulation of radiation fields, migration of radionuclides, spread of contamination in aqueous and air media, as well as for evaluation of exposure loads and risks for humans. The purpose of the present paper is to describe the structure and functional capabilities of the complex and to provide some examples of its application.
