The urgency of the work is due to the depletion of traditional fuel reserves and increasing the load on the biosphere because of emissions from burning coal, oil and gas. The solution of these problems are the development of nuclear energy. The advantages of nuclear energy are analyzed, namely: high calorific value of nuclear fuel, better economic indicators, less environmental pollution. The purpose of this work is to optimize the heat transfer processes in the secondary circuit of a nuclear power plant. It is proposed to take the second circuit of the third power unit of the Rivne nuclear power plant as the object of research. The need for knowledge of heat transfer processes and hydrodynamics is determined by the fact that nuclear reactors are energy-intensive thermal machines, in which these processes are manifested in a rather complex form. Therefore, measures to optimize heat transfer processes in the thermal circuit of the second circuit of the NPP in order to increase energy performance are considered. In order to remove from the system the hardness salts that settle on the walls of the equipment and impair the heat transfer processes, a reagent has been selected to bind the hardness salts. he addition of the PuroTech113 reagent to the working circuit of the secondary circuit made it possible to free the system from the deposition of hardness salts in it, as this reagent "binds" free calcium and magnesium ions. In turn, scale is no longer deposited on the walls of the heat exchange equipment, which allows to fully transferring the required amount of heat. Recalculation of the thermal balance showed that the efficiency of the unit is increased by 3%.The efficiency coefficient of the heat exchanger was chosen as the criterion of optimality. The efficiency of the heat exchanger in the general case is a function of the mode parameters, the scheme of mutual movement of heat carriers and features of hydrodynamics and heat transfer of real heat exchangers. The problem of optimizing the movement of heat carriers in intermediate heat exchangers is solved in paper.

AbstractIn the present world, nuclear energy is a must need for various purposes. The main cause of nuclear energy is because of the increasing energy demand, which is not possible to provide by using convenient energy generation. Bangladesh is a lower income country and the energy sector is not so developed here though there is a very high demand for energy. Rooppur Nuclear Power Plant is the only one nuclear generation plant which can provide this kind of huge energy within a very short time. This paper mainly depicts the ins and outs of this plant and discusses it’s feasibility in Bangladesh. It also focuses on the worlds various power generation methods and comprises it with nuclear energy generation. A detailed technical brief is presented in this paper along with advantages, location selection, financial and environmental impacts. This will help researchers to do further researches about nuclear energy in Bangladesh.

Nowadays, decommissioning of nuclear power plants has become a key issue for nuclear industry in Europe. The phasing out of nuclear energy in Germany, Belgium and Sweden, as well as the early closure of nuclear units in applicant countries in the frame of EU enlargement, has largely contributed to consider decommissioning as the next challenge to face. The situation is slightly different in France where nuclear energy is still considered as a safe, cost-effective and environment friendly energy source. Electricite´ de France (EDF) is working on the development of a new generation of reactor to replace the existing one and erection of a new nuclear power plant could start in the next few years. Nevertheless, to achieve this objective, it will be necessary to get the support of political decision-makers and the acceptance of public opinion. Due to the growing concern of these stakeholders for environmental issues, their support can only be obtained if it is possible to demonstrate that nuclear energy industry will not leave behind unsolved issues that will be a burden to the next generations. In this context decommissioning of the first generation of EDF NPPs constitutes a prerequisite for the erection of a new type of nuclear power plant. This paper will present the programme defined by EDF for the decommissioning of its nine already shutdown reactors (Fig. 1). The reasons of the recent evolution of EDF decommissioning strategy will be explained and the key issues that will contribute to the successful implementation of this programme will be addressed. Finally, what has been achieved on sites so far and major planned activities will be described.

The United Arab Emirates (UAE) is a developing affluent nation. The leaders of the UAE announced the pursuit of peaceful nuclear power in 2008 and by the end of the following year established its Nuclear Energy Program Implementing Organization (the Emirates Nuclear Energy Corporation (ENEC)), Federal Authority for Nuclear Regulation (FANR), and ordered four APR-1400 pressurized water reactors from the Korean Electric Power Company (KEPCO). Nuclear Engineering programs were initiated soon afterwards at Khalifa University for graduate students and the University of Sharjah for undergraduate students. The technical workforce including nuclear power plant local operators and chemistry and radiation protection personnel was established by ENEC and the Institute of Applied Technology as an inaugural program of Abu Dhabi Polytechnic (AD Poly) in 2011. This paper describes the development of the dual education and training program at AD Poly, the experience of the initial cohorts who conducted their training at the APR-1400 units at the Shin Kori Nuclear Power Plant in Korea, and the current program between the AD Poly Abu Dhabi campus and the new Barakah Nuclear Power Plant based on lessons learned from the earlier years.
