The article considers basic approaches to dismantling of nuclear-powered guided missile heavy cruisers on the example of the nuclear-powered guided missile heavy cruiser "Admiral Ushakov", as well as conceptual questions of safety during planned dismantling. The major factors that have impact on choosing the strategy of dismantling and on ensuring nuclear, radiation and ecological safety of the personnel, population and environment during dismantling are considered. The conclusion is that maintaining and servicing decommissioned nuclear powered ships and their reactor installations, along with operations in the course of subsequent dismantling of nuclear powered ships have no fundamental differences from the corresponding conditions and operations for nuclear submarines. “Shiprepairing Center “Zvezdochka” JSC has longterm experience of maintaining and dismantling nuclear submarines, including fuel discharge of dozens of marine reactor plants. This experience convincingly confirms high reliability of procedures (including on nuclear and radiation safety and on inadmissible impacts on environment) embedded into domestic projects of marine reactor plants, and acceptability of regulations and technologies applied by “Shiprepairing Center “Zvezdochka” JSC during corresponding operations including such potentially dangerous ones as discharging nuclear reactors and further treatment of the spent nuclear fuel.

The aim of the work is to develop control levels of specific total alpha-activity of water samples for a number of sources of centralized drinking water supply in the Republic of Khakassia on the basis of the results of long-term laboratory studies. Materials and methods. The analysis is carried out on the basis of the results of laboratory studies of water sources of centralized drinking water supply of the population of the Republic of Khakassia, performed by accredited testing laboratories of institutions of the state sanitary and epidemiological service of the Republic for the period from 2001 to 2018, using alpha-beta radiometric, alpha-spectrometric methods with radiochemical preparation of counting samples, gamma-spectrometric method. The control levels of specific total alpha-activity of water samples from the sources of centralized drinking water supply in the Republic of Khakassia were established by the statistical maximum – the sum of the average value with a doubled standard deviation, with the volume of research more than 30, and the maximum value with the volume of research less than 30. Results. About half of the studied water samples from the sources of the centralized drinking water supply of the Republic of Khakassia, annually, are noted with exceeding the control level of specific total alpha-activity (0,2 Bq/kg). The values obtained in the studied samples vary up to 5,57 Bq/kg. During the observation period, samples of water exceeding the reference level of specific total alpha-activity (0.2 Bq/kg) were identified in settlements of the Altai, Askizsky, Beysky, Bogradsky, Ordzhonikidzevsky, Tashtypsky, Ust–Abakansky, Shira districts and the city of Sorsk, smt. Prigorsk (Chernogorsk). In previous studies, it was found that high levels of specific total alpha-activity in the country are mainly due to natural radionuclides uranium-238 (238U), uranium-234 (234U). In a number of settlements of the Republic, the sum of the ratio of specific activities of natural radionuclides to the corresponding levels of intervention exceeds 1,0. Average annual individual effective doses of internal exposure to natural radionuclides of drinking water, at or above 0,1 mSv/year (values in the range of 0,1-0,2 mSv/year), which does not require urgent radiation protection measures. At the same time, monitoring of indicators of radiation safety of water sources of water supply should be carried out in accordance with the established requirements. In this connection, in order to improve control, for the rapid assessment of the radiation situation and making timely decisions to ensure radiation safety of the population, the calculation of control levels of specific total alpha-activity was carried out. As a result of calculations, specific values of control levels for each of water source were obtained. The calculated values range from 0,2 to 2,6 Bq/kg. Conclusion. The control levels are “site standards” and are calculated for each of the source of water supply. Their excess will be considered as a signal of “negative change” of the radiation situation”, which may be associated with an increase of the specific activities of 234U, 238U, or the appearance of highly radiotoxic radionuclides: 226Ra, 210Po, 228Ra.

Previous calculations showed that in the Kyrgyz Republic 7.2% of the total population are exposed to the “radiation risk”, in the Republic of Kazakhstan - about 3%, in the Republic of Tajikistan - 1.7% and in the Republic of Uzbekistan - 0.3%. The number of radiation-contaminated territories in the Republics of Central Asia is equal: the Kyrgyz Republic contains about 132 million m3 of waste, the Republic of Tajikistan contains about 180 million m3 of waste, the Republic of Uzbekistan contains 640 million m3 of waste, and the Republic of Kazakhstan contains approximately 10,000 million m3 of waste. Total: in the four Republics of Central Asia, the total amount of radioactive waste is 10952 million m3. Taking as a basis the limited liability company “Vismut GmbH” from Germany, which carried out the reclamation of uranium tailings with a volume of 160 million m3 of tailings at a cost of about 8 billion euros for about 37 years. Using a thermodynamic approach, it is shown that the costs of reclamation of uranium tailings for the four Central Asian Republics will be 548 billion euros, and the duration will be about 40 years.

A brief description of information system for nuclear material accounting developed for the national regulator in the field of nuclear and radiation safety - the Department for Nuclear and Radiation Safety of the Ministry of Emergency Situations of the Republic of Belarus (Gosatomnadzor) is given. The information system is a part of the Intellectual information system of a Gosatomnadzor employee to ensure control (supervision) in the field of nuclear and radiation safety. It is developed on the basis of free software. The system has been implemented in Gosatomnadzor and at present in the Republic of Belarus all nuclear material accounting with reporting to the IAEA is carried out with its help. The system, in full compliance with the IAEA requirements, provides automatic generation with all the necessary calculations based on the input data of the following reporting documents: physical inventory listing, inventory change report, material balance report, textual report, General Ledger. All reports are fully consistent each with other. An efficient mechanism has been developed for importing and exporting data from / to the system according to formats of fixed and labelled Code 10 required by the IAEA. All logs of the system describing reports contain a field “IAEA approved” (yes / no). If it set to “yes”, they are closed for editing and correction. A special tool has been developed for making adjustments to these documents in accordance with the IAEA rules. The system contains fully completed reference books (small journals referenced by all major journals in the database) with the necessary reference data in accordance with Code 10. The information system meets all the IAEA requirements for such systems of national regulators in the field of accounting, control and supervision of nuclear material. It can be easily translated into other languages and adapted for the needs of accounting and control of nuclear material in operating organizations.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
