Practice and Problems of Scientific Support for Nuclear Legacy Work

The main results of a scientific analysis of stopped nuclear and radiation dangerous objects performed within the framework of government programs are examined. Solved problems and tasks requiring further analysis are analyzed in the context of the following directions: the objectives and boundary conditions for safety analysis, development of a normative-legal base, inventorying and ranking of nuclear and radiation dangerous objects according to the level of potential danger, computational and experimental validation of safety, including the final state of the objects at mothballing, comprehensive engineering-radiation examination of nuclear and radiation dangerous objects, and development of new methods and technologies for decontamination and disassembly. Three groups of situations associated with the readiness of the solutions for adoption in practice are singled out on the basis of the analysis.
