According to national programs, radioactive waste from Ukrainian enterprises and territories contaminated in the Chornobyl accident is to be placed for long-term storage and disposal on the Vektor site. This multifactor and time-phase problem should be solved using a system analysis and considering the Vektor site as a whole for each new facility. The paper discusses radiological aspects that can be used to analyze the disposal of short-lived low- and intermediate-level waste on the Vektor site. Source

The stages of modernization of Ukrainian NPP I&C systems are described in the paper. The first stage (1993-2000) was characterized by use of systems designed by foreign (including USA) companies. The second stage (2001-2011) was characterized by use of systems designed by Ukrainian companies. The modernization strategy is analyzed in two aspects: the strategy of operators and the strategy of I&C systems designers. Some features peculiar to the strategy of designers are: an aggregate of hardware, software and service apparatus called "hardware-software complex" (HSC) as central part of systems, which are delivered to NPPs in full assembly and are connected to peripheral equipment at NPP; use of FPGA for performance of safety functions; elaboration of new equipment families. The third stage starts in 2012 and is related to construction of two new units (Khmelnitsky-3 and 4). A new regulatory framework, including regulatory requirements, will be elaborated for I&C systems of these units. Source

The paper analyzes links between the final disposal option and needs for long-term storage of radioactive waste taking into proposals on possible changes in radwaste classification as regards disposal. It considers the conceptual approach to design facilities for long-term storage of long-lived radioactive waste at the Vector site and approaches to apply requirements of regulatory documents, radiation safety principles and criteria for long-term storage of radwaste and safety assessment.

The paper describes analysis of national regulatory acts, documents of the International Atomic Energy Agency and the European Union Directives which contain requirements and recommendations on cyclotron production of isotopes and their application in diagnostics by method of positron-emission tomography. The objective was to define requirements for safety improvement of activities on cyclotron production of isotopes and their application in diagnostics by PET-method caused by inconsistency of the regulatory framework with the modern level of requirements and recommendations in this area.
