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.

At a height of 108 metres (355 feet), it is taller than New York's Statue of Liberty—while its weight of 36,000 tons is three times heavier than the Eiffel Tower in Paris. The 2.1-billion-euro ($2.2-billion) structure sponsored by the European Bank for Reconstruction and Development (EBRD) has been edged into place over an existing crumbling dome that the Soviets built in haste when disaster struck three decades ago. "We welcome this milestone in the process of the transformation of Chernobyl as a symbol of what we can achieve jointly with strong, determined and long-term commitment," EBRD president Suma Chakrabarti said in a statement. Radioactive fallout from the site of the world's worst civil nuclear accident spread across three-quarters of Europe and prompted a global rethink about the safety of atomic fuel. Work on the previous dome began after a 10-day fire caused by the explosion was contained but radiation still spewed out of the stricken reactor. "It was done through the super-human efforts of thousands of ordinary people," the Chernobyl museum's deputy chief Anna Korolevska told AFP. "What kind of protective gear could they have possibly had? They worked in regular construction clothes." About 30 of the cleanup workers known as liquidators were killed on site or died from overwhelming radiation poisoning in the following weeks. The Soviets sought to try to cover up the accident that was caused by errors during an experimental safety check and its eventual toll is still hotly disputed. The United Nations estimated in 2005 that around 4,000 people had either been killed or were left dying from cancer and other related diseases. But the Greenpeace environmental protection group believes the figure may be closer to 100,000. Authorities maintain a 30-kilometre-wide (19-mile) exclusion zone around the plant in which only a few dozen elderly people live. One of the main problems of the Soviet-era response was the fact that it only had a 30-year lifespan. Yet its deterioration began much sooner than that. "Radioactive dust inside the structure is being blown out through the cracks," Sergiy Paskevych of Ukraine's Institute of Nuclear Power Plant Safety Problems told AFP. Paskevych added that the existing structure could crumble under extreme weather conditions. The new arch should be able to withstand tremors of 6.0 magnitude—a strength rarely seen in eastern Europe—and tornados that strike the region only once every million years. Kiev has complained that European assistance was slow to materialise. The EBRD found 40 state sponsors to fund a competition in 2007 to choose who should build the massive moveable dome. A French consortium of two companies known as Novarka finished the designs in 2010 and began construction two years later. The shelter was edged towards the fourth reactor in just under three weeks of delicate work this month that was interrupted by bad weather and other potential dangers. It will later be fitted with radiation control equipment as well as air vents and fire fighting measures. The equipment inside the arch is expected to be operative by the end of 2017. "Only then will we begin to disassemble the old, unstable structure," the head of the State Nuclear Regulatory Inspectorate of Ukraine, Sergiy Bozhko, told AFP. But he said no timeframe had yet been set for the particularly hazardous work of removing all the remaining nuclear fuel from inside the plant or dismantiling the old dome. Novarka believes that its arch will keep Europe safe from nuclear fallout for the next 100 years.

Self-evaluation of the Ukrainian regulations on nuclear and radiation safety that apply to nuclear power plants for compliance with the reference levels of the Western European Nuclear Regulators Association (WENRA) is presented. Proposals on improvement of the regulations upon self-evaluation are provided.

The paper discusses aspects related to licensing, including development of the regulatory and legal framework on nuclear and radiation safety, and review of safety justification documents for the new nuclear subcritical facility that is currently designed and constructed by the National Science Center "Kharkov Institute of Physics and Technology". Basic design features of the neutron source are presented.

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.

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.
