Opis:
The article is an attempt to analyze the current situation and plans for the development of the nuclear industry in the Middle East after the failure in Fukushima. Next to the southern and eastern Asian countries nuclear power becomes a choice of countries of the Middle East region. Taking into account the significant gaps in economic and scientific potential, and the unstable political situation in the countries of the region – projects to build nuclear power stations seem to be a particularly complex challenge. The article analyzes the entered and planned investments and risks, which may arise in connection with the implementation of adopted plans.

Opis:
In a year and a half after the events of March 2011, Japan excluded all their nuclear reactors, returning to fossil fuels as a basis in the energy field. The shock associated with nuclear disaster seemed to indicate an ultimate end of Japanese adventure with the atom. The situation has, however, significantly changed during the last several months, and the first nuclear reactor connected again to the electric network, is a proof of the change of the energy policy. The article aims to identify the current state of knowledge on the future of nuclear energy in the Japanese energy sector and adjustments proposed in the future energy mix. At the same time, it is an attempt to analyze the reasons that led the current Government of Prime Minister Abe to take very unpopular decisions to return to nuclear energy.

Opis:
This article deals with the most pressing issues in the modern political-legal and security information agenda. The active hostilities on the territory of Ukraine have placed the world, and in particular the European Union, under the threat of a new artificial nuclear catastrophe, which could be provoked by the provocative actions of the Russian army at the Zaporizhzhia nuclear power plant. Considering the relevance of the issue, the object of study is the political and legal system of Ukraine in the context of nuclear safety, which has undergone significant changes under the influence of European integration. For comprehensive coverage of the issue, the study examines the evolution of nuclear safety both in Ukraine and the European Union. Particular attention is paid to both the development of legislation and the formation of regulatory authorities. An important component of this study is a detailed analysis of the legal framework of both Ukraine and the European Union. Due to this, it was possible to clearly determine the scale of influence of the specific legislative acts. The study confirmed the impact of European integration on the main laws of Ukraine related to nuclear safety and the need to bring Ukrainian nuclear safety regulatory documents into line with the legislation of the European Union. This article deals with the EU supranational regulators such as WENRA and ENSREG have a significant impact on the regulatory and legal framework for nuclear safety. Ukraine made many commitments to improve control and develop its own regulatory body – the State Regulatory Inspectorate, which received significant autonomy under the influence of European initiatives. It should be stated that the influence of European integration as a political process is so profound that it leads to conceptual changes in the legislative and even institutional framework. The conclusions provide a few suggestions for improving the response system to factors such as hostilities, including at the legal level.

Opis:
The paper presents the dynamic multivariable model of Nuclear Power Plant steam turbine. Nature of the processes occurring in a steam turbine causes a task of modeling it very difficult, especially when this model is intended to be used for on-line optimal process control (model based) over wide range of operating conditions caused by changing power demand. Particular property of developed model is that it enables calculations evaluated directly from the input to the output, including pressure drop at the stages. As the input, model takes opening degree of valve and steam properties: mass flow and pressure. Moreover, it allows access to many internal variables (besides input and output) describing processes within the turbine. The model is compared with the static steam turbine model and then verified by using archive data gained from researches within previous Polish Nuclear Power Programme. Presented case study concerns the WWER-440 steam turbine that was supposed to be used in ˙ Zarnowiec. Simulation carried out shows compliance of the static and dynamic models with the benchmark data, in a steady state conditions. Dynamic model also shows good behavior over the transient conditions.

Opis:
This paper examines the evacuation of people in the event of an emergency caused at a nuclear facility. The study describes the emergency preparedness of the Mochovce Nuclear Power Plant. The paper describes the proposal of the logistics solution and the implementation of protective and emergency preparation, which is determined by the internal emergency plan, based on the information flow in the event of an emergency and the activities of individual emergency response units. The above results indicate that the fewer people there are in one evacuated group, the longer the evacuation time will be. However, the reason is not the length of time to get to the assembly point itself, but the number of groups that must be created and therefore the higher number of trips that firefighters have to take. The optimal way to carry out this process safely, in the shortest possible time, could be to set up more groups of escorting firefighters, who would accompany groups with smaller numbers of evacuees. Strict preparation and adherence to pre-prepared instructions, based on logistical principles in the event of an emergency at a nuclear facility, minimizes loss of life and harm to the health of persons, and also damage to property or the environment.

The paper presents the concept of the objective function which is to allow the selection of optimal parameters of the district heating system using a nuclear power plant operating in partial cogeneration mode. The concept is based on research carried out a number of years ago as part of [10]. The size of annual expenses was proposed as the objective function, which allows to compare the operation of a nuclear power plant in partial cogeneration with selected variants of supply to the heating system (combined heat and power station or conventional power plant and a conventional heating station). The analysis allows selecting the optimal structure of the heat supply system, which will provide the highest economic efficiency.
W artykule przedstawiono koncepcję funkcji celu, która ma umożliwiać dobór optymalnych parametrów systemu zaopatrzenia w ciepło aglomeracji miejskiej z wykorzystaniem elektrowni jądrowej pracującej w częściowym skojarzeniu. Koncepcja opiera się na badaniach przeprowadzonych przed laty w ramach pracy [10]. Jako funkcję celu zaproponowano wielkość kosztów rocznych, co pozwala na porównanie pracy uciepłownionej elektrowni jądrowej z wybranymi wariantami zasilania systemu ciepłowniczego (elektrociepłownia lub elektrownia konwencjonalna oraz ciepłownia klasyczna). Analiza umożliwia dokonanie wyboru optymalnej struktury systemu zaopatrzenia w ciepło, która zapewni najwyższą efektywność ekonomiczną.

Long-term results of ground-level air radionuclide contamination at the Russian coast of the Baltic Sea (nuclear facilities in the vicinity of the town of Sosnovy Bor) are under consideration. As compared with 1992-1997 [1], the Leningrad Nuclear Power Plant (NPP) equipment hermetic sealing (in 1998-1999) caused both the reduction of detection frequency of 131I aerosol and the maximum concentrations of 137Cs in the ground-level air at the NPP site. Long-term weekly nuclides' concentration time series were examined by the correlation analysis. Results of the analysis are presented. The seasonal fluctuations of 7Be concentrations in the ground-level air were examined by the harmonic (Fourier) analysis. The seasonal fluctuations of its concentrations with the maximum in spring-summer period are shown.

Opis:
In commercially available generation III and III+ PWR (pressurized water reactor) reactors, pressure of steam produced in steam generators varies in a relatively wide range from 5.7 to 7.8 MPa. Therefore, it is important to ask which value of steam pressure should be used for a specific unit, taking into account different location conditions, the size of the power system and conditions of operation with other sources of electricity generation. The paper analyzes the effect of steam pressure at the outlet of a steam generator on the performance of a PWR nuclear power plant by presenting changes in gross and net power and efficiency of the unit for steam pressures in the range of 6.8 to 7.8 MPa. In order to determine losses in the thermal system of the PWR power plant, in particular those caused by flow resistance and live steam throttling between the steam generator and the turbine inlet, results concerning entropy generation in the thermal system of the power plant have been presented. A model of a nuclear power plant was developed using the Ebsilon software and validated based on data concerning the Olkiluoto Unit 3 EPR (evolutionary power reactor) power plant. The calculations in the model were done for design conditions and for a constant thermal power of the steam generator. Under nominal conditions of the Olkiluoto Unit 3 EPR power unit, steam pressure is about 7.8 MPa and the steam dryness fraction is 0.997. The analysis indicates that in the assumed range of live steam pressure the gross power output and efficiency increase by 32 MW and 0.735 percentage point, respectively, and the net power output and efficiency increase by 27.8 MW and 0.638 percentage point, respectively. In the case of all types of commercially available PWR reactors, water pressure in the primary circuit is in the range of 15.5−16.0 MPa. For such pressure, reducing the live steam pressure leads to a reduction in the efficiency of the unit. Although a higher steam pressure increases the efficiency of the system, it is necessary to take into account the limitations resulting from technical and economic criteria as well as operating conditions of the primary circuit, including the necessary DNBR (departure from nucleate boiling ratio) margin. For the above reasons, increasing the live steam pressure above 7.8 MPa (the value used in EPR units that have already been completed) is unjustified, as it is associated with higher costs of the steam generator and the high-pressure part of the turbine.

Nuclear Power Plant in Poland
Opis:
Nowa runda dyskusji o budowie elektrowni jądrowej w Polsce pojawia się mniej więcej co pół roku w prasie i innych mediach. Tym razem „Dziennik – Gazeta Prawna” opublikował nieoficjalną informację o decyzji podjętej przez rząd. Już tego samego dnia została ona zdementowana przez ministra energii, który stwierdził, że toczą się tylko dyskusje na szczeblu rządowym. Publikacja zawiera listę doniesień na ten temat, które zostały skomentowane przez autora i uzupełnione uwagami opartymi o wieloletnie zajmowanie się technicznymi zagadnieniami budowy elektrowni jądrowej w Polsce.
A new round of discussions about the construction of a nuclear power plant in Poland usually commences in newspapers and other media approximately every half year. “Dziennik - Gazeta Prawna” published unofficial information that a decision in this regard had been reached by the government. It was denied on the same day by the Minister of Energy who said that this was only a governmental consultation. The list of few publications (in Polish) on this topic is presented and followed by the authors views and comments based on his many years of experience concerning technical aspects in the construction of NPP in Poland.

Opis:
The nuclear accidents of Fukushima in March 2011 have indicated the significance of external hazards for nuclear installations safety. One lesson learned from post-Fukushima investigations worldwide is that the operating experience from external hazards, even if these did not pose any significant harm to the affected plant, do represent important precursors, which should be taken into account in deterministic as well as probabilistic safety assessment. This paper provides an overview on the significance of events or event combinations involving hydrological external hazards. Some more recent examples of events from hydrological external hazards and their potential safety significance for nuclear power plants are discussed.

ORIGEN code is a widely used computer code for calculating the buildup, decay, and processing of radioactive materials. During the past few years, a sustained effort was undertaken by ORNL to update the original ORIGEN code [4] and its associated data bases. The results of this effort were updated on the reactor model, cross section, fission product yields, decay data, decay photon data and the ORIGEN computer code itself. In this paper we have obtained concentration changes of uranium and plutonium isotopes by ORIGEN code at different burn-up and then the results have been compared with VVER-1000 results in the first fuel cycle for fuel assemblies with 1.6% enrichment in the BUSHEHR Nuclear Power Plant.

Artykuł przedstawia przegląd dokonań w energetyce jądrowej na świecie w 2022 r. oraz podsumowanie wydarzeń w Polsce, które wcześniej już były przedstawiane w PTJ w 2022 r. Ogólnie moc zainstalowana w elektrowniach jądrowych i liczba budowanych reaktorów na świecie wzrosła. Niezmiennie najwięcej jest budowanych reaktorów na Dalekim Wschodzie, a jednym krajem, gdzie rozpoczęła się budowa dwóch pierwszych reaktorów był Egipt. W Polsce, jak napisano, dokonano wyboru dostawcy reaktorów do pierwszej elektrowni na Pomorzu, którym będzie Westinghouse. Nieoczekiwanie pojawił się nowy dostawca, którym ma być koncern Korea Hydro & Nuclear Power (KHNP) z Korei Południowej, a elektrownia ma powstać w Pątnowie wspólnie z Zespołem Elektrowni Pątnów Adamów Konin (ZE PAK) i Polską Grupą Energetyczną (PGE SA). Poza tym obserwuje się wzrost liczby firm zainteresowanych budową małych reaktorów modułowych (SMR). Lista tych dawnych i nowych firm jest długa, to: (1) Orlen Synthos Green Energy, Ciech i Unimot, (2) KGHM i Tauron, (3) Last Energy Polska, (4) Respect Energy, (5) PKN Orlen i (6) Świętokrzyska Grupa Przemysłowa INDUSTRIA oraz (7) Narodowe Centrum Badań Jądrowych.
The article presents an overview of achievements in nuclear energy in the world in 2022 and a summary of events in Poland, which were previously presented in PTJ in 2022. In general, the installed capacity of nuclear power plants and the number of reactors under construction in the world increased. Invariably, the largest number of reactors are built in the Far East, and one country where construction of the first two reactors began was Egypt. In Poland, as it was written, the supplier of reactors for the first power plant in Pomerania was selected, which will be Westinghouse. Unexpectedly, a new supplier has appeared, which is to be the KHNP concern from South Korea, and the power plant is to be built in Pątnów together with ZE PAK and PGE SA. In addition, there is an increase in the number of companies interested in building small modular reactors (SMR). The list of these old and new companies is long: (1) Orlen Synthos Green Energy, Ciech and Unimot, (2) KGHM and Tauron, (3) Last Energy Polska, (4) Respect Energy, (5) PKN Orlen, (6) Świętokrzyskie Industrial Group INDUSTRIA and (7) National Center for Nuclear Research.
