Abstract:

Abstract This study evaluates the functional requirements of the Super Proton-proton Collider (SPPC) beam screen in view of the CEPC-SPPC project about to be built in China and aims to prove the feasibility of using the scaled FCC-type beam screen. Moreover, the study puts forward several feasible updated schemes with extra-cooling to optimize the cryogenic efficiency under the 12.8 W/m synchrotron radiation (SR) heat load and decrease the leaked SR power to the cold bore. The power distribution calculated by Synrad+ is imported into the Ansys workbench to get the exact thermal profile. The results show that the new scheme can restrict the temperature rise within 1 K, with a 30 g/s mass flow rate of the coolants. Such a profile can save over 1.3 MW electric power per turn.

Abstract:

The paper involves the subject and the chosen results of up to now solving of work package “Development of advanced surface treatment of components used in parts of turbines working under the condition of operational temperatures of steam using the HP/HVOF technology of thermal spraying” of the Competence Centre project “Centre of Research and Experimental Development of Reliable Energy Production”. The subject belongs to the field of material engineering and results of solving contribute to fulfilling the main project aim, which is a long time safeguarding of safe, reliable and financially available both classical thermal and nuclear sources of electric power, which consists in extending service life of existing and building new turbo generator blocks. The erosion wear resistance is one of the areas, which were observed. The impact of hard particles on the surface under variable impact angles was simulated in laboratory conditions using an in-house equipment. The wear resistance of selected HVOF sprayed hardmetal and super-alloy coatings was measured and the wear mechanism was evaluated. A strong influence of impact angle on both material volume loss and wear mechanism was monitored. The superior erosion wear properties of super-alloy coatings were proved, regardless the higher hardness of hardmetal coatings.

Abstract:

Existing conditions make possible obtaining information that being discussed openly by wide scientific community could help outlining or even establishing the expediency of a particular area of present and future research. Use link http://www.sciencedirect.com to learn about the topics or areas that most attract researchers from different countries. The Generation IV International Forum (GIF-IV) established in January 2000 has set a goal to improve the new generation of nuclear technologies in the following areas: stability, safety and reliability, economic competitiveness, proliferation resistance and physical protection. The purpose of the present publication is to prepare a discussion of one of the directions of development of fourth-generation NPPs, the groundwork for which has already been laid in thermal power engineering in various countries. The number of papers published annually on this topic is the largest among other similar topics dedicated to nuclear power plants of the fourth generation. Judging from the operating experience of existing nuclear power plants using water as a coolant, it can be ascertained that the tendency of building water-cooled nuclear power plants will remain during the next 30 to 50 years. During the present stage the task in the development of alternative types of reactors will be limited to demonstration of their performance and acceptability for future power engineering and the society. The project of supercritical water-cooled reactor is based on the operating experience of VVER, PWR, BWR reactors (more than 14,000 reactor-years); many years of experience accumulated in operating fossil thermal power plants (more than 400 power units; 20,000 years of operation of power units) using supercritical (25 MPa, 540°C) and super-supercritical (35–37 MPa, 620–700°C) water steam. In Russia more than 140 supercritical pressure units are currently in operation. Numerical calculation and design of supercritical water-cooled reactor (similarly to BR-10 reactor) will allow not only training personnel for future development of this technology, but will also help revealing the most difficult points requiring experimental confirmation with application of independent test facilities, as well as formulating the plan of first priority experimental studies. Knowledge accumulated over the last 10 years in the world allows the following: further specifying the already developed concept; developing a plan of specific priority studies; compiling task order for designing small-power pilot VVER SKP-30 reactor (30 MW-th). The scope of problems that are to be solved to substantiate VVER-SCP reactor and commence designing an experimental reactor with thermal capacity of 30 MW is the same as that in developing any type of nuclear reactor: physics of the reactor core; material related matters (primarily concerned with the reactor pressure vessel, fuel, and fuel rod cladding); thermal hydraulics of rod bundles in the near- and supercritical areas; water chemistry at supercritical pressure; corrosion of materials, development of safety systems. Research must be carried out both in static conditions and under irradiation. The absence in Russia during the extended time period of approved program with allocation of appropriate funding and preservation of the existing status during the coming two or three years will lead to the situation when Russia will be hopelessly lagging behind in the development of SCWR technology.

Abstract:

Super-thick shallow granites without a cap layer are widely distributed in the Wendeng geothermal field. To evaluate the field’s productivity potential for an enhanced geothermal system (EGS), we carried out field tests, laboratory tests and numerical simulations in succession. The geothermal characteristics and deep rock mechanical properties were identified based on real geological and core data from the borehole ZK1 in Wendeng geothermal field. Then, a numerical model of reservoir hydraulic fracturing based on a discrete fracture network was established. Thermal extraction simulations were then conducted to assess the long-term productivity of an EGS project based on the fracturing results. Possible well layout patterns and operational parameters were considered. Results indicated that, for naturally fractured formations, large well spacings should be used and reservoirs with overdeveloped natural fractures should not be selected. For the same reservoir, created by stimulation, the production performances of five-spot and triplet-well modes were different. The pressure indicator was more sensitive to the choice of well layout mode than the temperature indicator. The power generation of the five-spot well mode was slightly improved above that of the triplet-well mode. When selecting the target reservoir, the formations with high temperatures, moderate natural fractures, and high in-situ stress shielding are preferable. On this basis, a large volume of fracturing fluids should be injected to stimulate the reservoir, making the reservoir length and width as large as possible. If the desired large-scale reservoir is created, the five-point well mode should be selected.

Abstract:

The European Spallation Source ESS has still a huge upgrade potential by using an accelerator ring structure for proton pulse compression that can change the long pulse to a medium pulse structure. Therefore, we consider the performance of a medium pulse structure on the existing ESS target, moderator and neutron instrumentation. A medium proton pulse will enhance the neutron peak brightness of thermal and cold neutrons by about one order of magnitude and even up to two orders of magnitude at shortest wavelengths used at ESS, largely increasing the performance of the ESS instruments for neutron scattering. The arguments for a medium pulse length are that it is best adapted to the resolution requirements of the ESS instruments, the coupled moderator, the typical long instruments; furthermore, that it seems feasible to realise a medium pulse length by advanced, slow extraction from an accelerator ring, and feasible for the rotating tungsten target to take the high-power load. We discuss the implications of a medium proton pulse length and its specific choice for the instrument resolution, and for moderator and target. The proposed upgrade is stimulated by the new project ESSnuSB for a neutrino super beam at ESS and motivated by the synergy effect of using a common pulse compressor ring. The upgrade will be a most economical and efficient path for the ESS to a next higher level from an already world leading long-pulse source, transforming with a medium pulse structure into an even much more powerful, future next generation neutron source.

Abstract:

Abstract Super-Kamiokande (SK) is the world’s largest underground water Cherenkov detector. The latest phase of operations began in July 2020 when, in order to improve neutron detection efficiency, about 13 tons of gadolinium (Gd) sulfate octahydrate was dissolved into SK’s pure water. Gd has a large thermal neutron capture cross section and emits visible gamma rays. This first loading marked the start of what is now called SK-Gd, and stable physics data taking has been ongoing since then. This presentation will focus on details of the first Gd loading and the detector status including detector calibrations. Also, the future plan and the prospect of observations with SK-Gd will be discussed.

Abstract:

This thesis focuses on the design and implementation of an economical and energy efficient DC Light Bulb for the DC House Project. For the DC lighting system, emphasis is on the DC-DC LED driver, dimmer circuit, LED lighting array, and physical packing design. In this paper, a DC Light Bulb is designed, simulated, and tested to operate at a wide input voltage ranging from 24 VDC to 72 VDC, to be fully dimmable using pulse-width modulation technique, and to produce lumination intensities equivalent to a standard 100 W A19 incandescent light bulb at one-tenth the total power consumption. The DC Light Bulb’s physical design also takes advantage of the same physical dimensions of a standard A19 incandescent light bulb using an E26 Edison screw base. Results from computer simulations and hardware tests demonstrated the feasibility of the proposed DC Light Bulb in terms of overall efficiency, line regulation, load regulation, power consumption, total lumens, luminous efficacy, and thermal profile.

Abstract:

Bhopal gas tragedy was an eyeopener in the field of safety management in Indian industries. Developed countries has done considerable amount of research on managing safety at organisations, such research practices has not been observed extensively in India. Indian industries were forced to adopt better safety management after globalisation and economic reforms to stay competitive in international markets. Safety management concepts are still confusing to the leaders of industries. So it is extremely important to study various factors that influence safety management, especially in high-risk industries like chemical/process industry. JSW Energy is one of the earliest private entrants into the power sector positioned strongly as a full-spectrum integrated power company with a presence across the power sector value chain. With 4531 MW operational capacity, it remains one of the most efficient Power Company in the country. The present study is conducted at JSW Energy, Ratnagiri is 4 x 300 MW thermal power plant. The objective of the study is to critically analyse the safety management system present in JSWEL, a coal based power generation project and give feedback to the management towards improving health and safety management system. During the study the important sections of safety management system were studied through visual inspection, interviewing key personnels and collecting information from documented data of the company. A detailed report on key areas of safety management was made and listed below. The report follows a detailed description of the different safety management systems of the JSW Ratnagiri thermal power plant. This can be useful for different industries who are striving to establish a proper safety management system.

Abstract:

In 1997, five Japanese gas turbine manufacturers — Kawasaki Heavy Industries, Ishikawajima-Harima Heavy Industries, Daihatsu Diesel, Niigata engineering, and Yanmar — joined forces to establish the Technological Research Association for Super Marine Gas Turbine (SMGT) and embarked on development of a next generation gas turbine for the maritime industry. The goal of this project was to develop a marine gas turbine with high thermal efficiency (38–40%) and low NOx emissions of less than 1g/kWh. In 2003, this project was completed with success. SMGT is a two shaft, re-generative cycle gas turbine with an axial-radial compressor, multi-can dry low emission combustor, air cooled gas generator, power turbine, and a recuperator. Additionally, the new technologies incorporated into the SMGT deliver high performance and low emissions. Development of the commercial version, the SMGT2, followed, and the program came to a successful end in 2005. The three purposes of development were to improve the design of the power turbine and recuperator, to prove durability using endurance bench tests, and to apply a waste heat recovery system. Using a waste heat recovery boiler and an inlet cooler with an absorption chiller, energy efficiency improved by 50% and shaft output increased to 2,300kW, even when at high ambient temperatures. High energy efficiency reduces fuel consumption, thus reducing the cost of operating a vessel.

Abstract:

In order to prevent global warming, Kyoto Protocol has come into effect in February 2005. It is necessary for Japan to reduce 6% of amount of CO2 emission from 2008 to 2012. In such an environment, improvement of the thermal efficiency of the gas turbine for GTCC is highly required. Mitsubishi Heavy Industries, Ltd. participates in the national project developing 1700 degC gas turbine. In this national project, selected component technologies are investigated in detail. Key technologies for 1700degC gas turbine are determined and under development such as: (1) Combustor with exhaust gas recirculation system; (2) Turbine cooling technology; (3) Super heat resistant material; (4) Thermal barrier coating; (5) High efficiency high loading turbine; (6) High pressure high efficiency compressor. Current status of the technology developments is reviewed.

Abstract:

Abstract Direct-fired super-critical carbon dioxide (sCO2) power cycles, are a potential method for efficiently capturing nearly all of the CO2 emissions from burning fossil fuels. Direct-fired sCO2 cycles require a very high degree of recuperation, which in turn means that the inlet temperature to the combustor is significantly higher than would typically be seen in a similar gas turbine combustors. Previous efforts have shown that combustor inlet temperatures of around 700 °C are to be expected for a cycle with around 1200 °C combustor exit temperatures [1]. This high inlet temperature means that bypass gasses are extremely hot, which poses some difficulties for the design of the combustion system, especially thermal management of the combustor liner and injectors in the 200 bar sCO2 environment.

Abstract:

Abstract Direct-fired super-critical carbon dioxide (sCO2) power cycles are a potential method for efficiently capturing nearly all of the CO2 emissions from burning fossil fuels. Direct-fired sCO2 cycles require a very high degree of recuperation, which in turn means that the inlet temperature to the combustor is significantly higher than would typically be seen in a similar gas turbine combustor. Previous efforts have shown that combustor inlet temperatures of around 700°C at 200 bar are to be expected for a cycle with around 1200°C combustor exit temperatures. The project team led by Southwest Research Institute is in the process of building and commissioning a 1MW scale direct-fired sCO2 oxy combustor. The test rig at SwRI uses laser ignition and advanced optical access to monitor combustion and characterize behavior. This paper will detail some of the challenges associated with the design and fabrication of the combustor and sCO2 power loop. These obstacles include thermal management, water generation, and constituent monitoring. The first ever unsteady simulations of this type of combustor were conducted as part of the design process. A presentation of the test rig layout, design considerations, and integration challenges will be covered.

Abstract:

Abstract Enhancement of the steam conditions is one of the most effective measures to achieve the goal of higher thermal efficiency. 700°C class A-USC (Advanced Ultra Super Critical Steam Conditions) power plant is one of the remarkable technologies to achieve the goal and reduce CO2 emissions from fossil fuel power plants. Toshiba has been working on the A-USC development project with subsidy from METI (Ministry of Economy, Trade and Industry) and NEDO (New Energy and Industrial Technology Development Organization). In this project, A-USC power plants with steam parameters of 35MPa 700/720/720°C were considered. To date, various materials have been developed and tested to verify their characteristics for use in A-USC power plants. And some of these materials are being investigated as to their suitability for use in long term. Together with members of the project, we carried out the boiler component test using a commercially-operating boiler. We manufactured a small-scale turbine casing made of nickel-based alloy, and supplied it for the test. In addition, we manufactured a turbine rotor for turbine rotation tests, and carried out the test at 700°C and rotating speed of 3,600rpm conditions. In this paper, we show the results of the A-USC steam turbine development obtained by the project.

Abstract:

Abstract CO2 emission reduction from coal power plants is still a serious issue to mitigate the impact of global warming and resulting climate change, though renewables are growing today. As one of the solutions, we developed A-USC (Advanced Ultra Super Critical steam condition) technology to raise the thermal efficiency of coal power plants by using high steam temperatures of up to 700℃ between 2008 and 2017 with the support of METI (Ministry of Economy, Trade and Industry) and NEDO (New Energy and Industrial Technology Development Organization). The temperature is 100℃ higher than that of the current USC technology. Materials and manufacturing technology for boilers, turbines and valves were developed. Boiler components, such as super heaters, a thick wall pipe, valves, and a turbine casing were successfully tested in a 700℃-boiler component test facility. Turbine rotors were tested successfully, as well, in a turbine rotating test facility under 700℃ and at actual speed. The tested components were removed from the facilities and inspected. In 2017, following the component tests, we started a new project to develop the maintenance technology of the A-USC power plants with the support of NEDO. A pressurized thick wall pipe is being tested in a 700℃ furnace to check the material degradation of an actual sized component.

Abstract:

Abstract In Japan, a research and development project is ongoing that is aimed at developing supercritical geothermal exploration and power generation methods. The extremely high formation temperatures encountered during supercritical geothermal drilling presents a challenge for the durability of downhole tools. Thus, it is essential to design an effective method of downhole cooling during drilling. To protect commonly used downhole tools from thermal damage, the objective is to reduce the downhole temperature in supercritical geothermal wells to below 175°C, which coincides with the lowest heat resistant temperature of most downhole equipment. In this study, the authors carried out numerical simulations focusing on the effectiveness of using insulated drill pipes to reduce downhole fluid circulation temperatures during drilling through formations with temperatures high enough for a supercritical reservoir. It was found that use of insulated drill pipes effectively controlled the downhole temperature by reducing the heat influx conducted from the formation. Considering the additional cost of using insulated drill pipes, we also looked at cases where the insulated drill pipes were only applied along two-thirds of the entire drillstring. Considering the flow rate of the circulating fluid and the inflow temperature, the temperature simulation was performed to keep the downhole temperature below 175°C. We also considered the additional pressure loss that could be expected from using the narrower insulated drill pipe.

Abstract:

The research project aiming to commercialize 700°C class pulverized coal power system; advanced ultra-super critical (A-USC) pressure power generation has been conducted in Japan from 2008. In A-USC boilers, Ni base or Ni-Fe base alloys are used for high temperature parts at 650–700°C and advanced high Cr ferritic steels are planning to be used at the temperatures lower than 650°C. Because the high B-9Cr steel developed in National Institute for Materials Science (NIMS) has improved creep strength in weldments, it is one of the candidate materials for A-USC boilers. In the present paper, the creep tests of the dissimilar welds between high B-9Cr steels and Ni base alloys were conducted. In the heat affected zone (HAZ) of the high B-9Cr steels, fine-grained microstructures were not formed and grain size of the base metal was retained. Free boron on the grain boundaries is considered to affect the mechanisms of the α-γ transformation during weld thermal cycle. Consequently, the creep rupture lives of the dissimilar welds between high B-9Cr steels and Ni base alloys were 5–10 times longer than those of the conventional 9Cr steel welds at 650°C.

Abstract:

This evaluation conducts an ex post review of the mitigation measures in the Samalayuca II and Monterrey III thermal power generation projects in Mexico. In general, it can be concluded that both thermoelectric power plants took into account most of the environmental impacts and mitigation measures recommended by the literature. A more active role in project design, supervision, and monitoring by the IDB would increase the technical value added. Social action plans need to be considered, as well as local community participation during project design and monitoring. Targeted studies to solve environmental problems can reduce uncertainty when choosing alternatives for managing associated risks. The participation of multidisciplinary teams and local specialists in the drafting of evaluation and monitoring reports would strengthen the technical aspects of the reports.

Abstract:

This is the final report summarizing work completed during the first phase of the PRCI study on large bore two stroke lean burn integral compressor engine response to variable natural gas compositions for the purposes of engine control development. Accomplished tasks include the completion of a detailed literature review covering the research topic, a parametric study of laminar flame speeds and ignition delays for binary methane and ethane mixtures up to 30%, and a GT-Power engine model of the Colorado State GMV-4 research engine with associated validation data from CSU�s variable ethane effects study. The chemistry of the combustion reaction is crucial to accurate modeling; laminar flame speeds and ignition delays as function of composition were determined from the solutions to published chemical kinetics mechanisms GRI-Mech3.0 and Saudi Aramco Mech1.3, respectively. The Wiebe coefficients correlated to variations in ethane composition and spark timing were regressed from the crank angle resolved heat release rates. The Wiebe coefficients are the most significant achievement of this phase of the project, since they quantify the heat release as a function of composition. At this time, the Wiebe parameters only reflect the relative changes in the model since certain aspect of the models geometry are pending resolution. Future phases of the project could use the developed GT-Power model and Wiebe coefficients for development of control schemes that maintain emissions, speed and torque limits, and maximize thermal efficiency during a variable fuel composition event.

Abstract:

The findings reported in this paper provide insights into the power dynamics and distributional politics that shape resistance to phasing out coal and to opportunities for change, as part of a broader project comparing these lessons and experiences in Colombia, South Africa and Indonesia, aiming to understand challenges to a just energy transition in coal-producing countries in the Global South. The current Colombian government has helped centre the concept of a just energy transition in public debate, encompassing a broad range of questions and concerns. National, regional and local discussions have different frameworks and visions for a future beyond fossil fuels, particularly regarding coal, which is a major export commodity but not a major fuel for domestic use in Colombia. For thermal coal–producing regions in Colombia, this debate touches on the challenges of both the legacy of extractive activities and the repercussions of losing a significant industrial sector, affecting local and regional economies and communities. Drawing on a series of workshops, a literature review, and interviews around transitions from coal in the Colombian departments of Cesar and La Guajira, researchers identified different visions of a just energy transition put forward at the national and regional levels, as well as some of the interests and strategies leveraged by different actors and groups in pushing certain visions of such a transition. In addition to presenting these results, the authors of this report provide insights into the power dynamics that shape resistance to phasing out coal and opportunities for transitions to more sustainable futures, with a strong emphasis on the efforts of civil society to create and achieve their visions of transition.
