Thermal Hydraulics Analysis of the Distribution Zone in Small Modular Dual Fluid Reactor
metals Article Thermal Hydraulics Analysis of the Distribution Zone in Small Modular Dual Fluid Reactor Chunyu Liu 1,* , Xiaodong Li 1 , Run Luo 1,2 and Rafael Macian-Juan 1 1 Chair of Nuclear Technology, Department of Mechanical Engineering, Technical University of Munich (TUM), Boltzmannstr. 15, 85748 Garching, Germany; [email protected] (X.L.); [email protected] or [email protected] (R.L.); [email protected] (R.M.-J.) 2 School of Resource & Environment and Safety Engineering, University of South China, No. 28, Changsheng West Road, Hengyang 421001, China * Correspondence: [email protected] or [email protected] Received: 29 June 2020; Accepted: 4 August 2020; Published: 6 August 2020 Abstract: The Small Modular Dual Fluid Reactor (SMDFR) is a novel molten salt reactor based on the dual fluid reactor concept, which employs molten salt as fuel and liquid lead/lead-bismuth eutectic (LBE) as coolant. A unique design of this reactor is the distribution zone, which locates under the core and joins the core region with the inlet pipes of molten salt and coolant. Since the distribution zone has a major influence on the heat removal capacity in the core region, the thermal hydraulics characteristics of the distribution zone have to be investigated. This paper focuses on the thermal hydraulics analysis of the distribution zone, which is conducted by the numerical simulation using COMSOL Multiphysics with the CFD (Computational Fluid Dynamics) module and the Heat Transfer module. The energy loss and heat exchange in the distribution zone are also quantitatively analyzed. The velocity and temperature distributions of both molten salt and coolant at the outlet of the distribution zone, as inlet of the core region, are produced. -
小型飛翔体/海外 [Format 2] Technical Catalog Category
小型飛翔体/海外 [Format 2] Technical Catalog Category Airborne contamination sensor Title Depth Evaluation of Entrained Products (DEEP) Proposed by Create Technologies Ltd & Costain Group PLC 1.DEEP is a sensor analysis software for analysing contamination. DEEP can distinguish between surface contamination and internal / absorbed contamination. The software measures contamination depth by analysing distortions in the gamma spectrum. The method can be applied to data gathered using any spectrometer. Because DEEP provides a means of discriminating surface contamination from other radiation sources, DEEP can be used to provide an estimate of surface contamination without physical sampling. DEEP is a real-time method which enables the user to generate a large number of rapid contamination assessments- this data is complementary to physical samples, providing a sound basis for extrapolation from point samples. It also helps identify anomalies enabling targeted sampling startegies. DEEP is compatible with small airborne spectrometer/ processor combinations, such as that proposed by the ARM-U project – please refer to the ARM-U proposal for more details of the air vehicle. Figure 1: DEEP system core components are small, light, low power and can be integrated via USB, serial or Ethernet interfaces. 小型飛翔体/海外 Figure 2: DEEP prototype software 2.Past experience (plants in Japan, overseas plant, applications in other industries, etc) Create technologies is a specialist R&D firm with a focus on imaging and sensing in the nuclear industry.

Along with the growth of population and economy, it is undeniable that the energy needs of Indonesia also continues to increase rapidly. Most of the source of this energy needs are from non-renewable/ fossil energy such as petroleum, natural gas and coal, and the utilization of it will produce greenhouse gas emissions (GHG) that contribute to global warming and climate change. To improve national energy security in the long term and contribute to global efforts to put a half to climate change, energy conservation and energy diversication through the development of sustainable renewable energy is a necessity. WWF's vision in the energy sector is to encourage the achievement of 100% Renewable Energy in 2050 globally. -

Abandoned Mines Can Be Used As Geothermal Energy Source
17 February 2011 Abandoned mines can be used as geothermal energy source Scientists have reviewed the potential for worldwide development of geothermal energy systems in old, unused mines. The technology is proven in many sites and could therefore help increase the share of renewable energy sources in the energy mix, offering sustainability and job creation, which may make mining operations more appealing to investors, communities and policymakers. The mineral industry is energy intensive and is therefore focusing on developing energy efficiency and cleaner production technologies. It is also expensive to open, operate and close mines, but few are ever considered as being useful once they have been closed. They are often located on marginal, unproductive land in remote, harsh environments and nearby communities may only live in the area as a direct result of the mine. Being often highly dependent on the mine and on imports of (fossil) fuel, such communities are highly unsustainable. The researchers argue that mines could be used post-closure for energy generation (heating and cooling) using the natural heat contained in the mine water. Geothermal energy systems could be implemented to extract this heat using heat pumps, from both closed and potentially working mines. This would offer local employment and energy resilience to the surrounding communities. Other uses of the energy may include melting snow on icy roads (instead of using salt) or supplying heat for fish farms and greenhouses. Several other technologies can extract energy from abandoned mines, including compressed air storage or the direct use of warm mine water to regulate the temperature of microalgae raceway ponds, allowing a longer growing season for cultivation; key products that can be obtained from the microalgae include nutraceuticals and biofuels. -

Microgeneration Strategy: Progress Report
MICROGENERATION STRATEGY Progress Report JUNE 2008 Foreword by Malcolm Wicks It is just over two years since The Microgeneration Strategy was launched. Since then climate change and renewables have jumped to the top of the global and political agendas. Consequently, it is more important than ever that reliable microgeneration offers individual householders the chance to play their part in tackling climate change. In March 2006, there was limited knowledge in the UK about the everyday use of microgeneration technologies, such as solar thermal heating, ground source heat pumps, micro wind or solar photovolatics. Much has changed since then. Thousands of people have considered installing these technologies or have examined grants under the Low Carbon Buildings Programme. Many have installed microgeneration and, in doing so, will have helped to reduce their demand for energy, thereby cutting both their CO2 emissions and their utility bills. The Government’s aim in the Strategy was to identify obstacles to creating a sustainable microgeneration market. I am pleased that the majority of the actions have been completed and this report sets out the excellent progress we have made. As a consequence of our work over the last two years, we have benefited from a deeper understanding of how the microgeneration market works and how it can make an important contribution to a 60% reduction in CO2 emissions by 2050. Building an evidence base, for example, from research into consumer behaviour, from tackling planning restrictions and from tracking capital costs, means that we are now in a better position to take forward work on building a sustainable market for microgeneration in the UK. -

Nornickel and the Kola Peninsula
THE BELLONA FOUNDATION Nornickel and the Kola Peninsula Photo: Thomas Nilsen ENVIRONMENTAL RESPONSIBILITY IN THE YEAR OF ECOLOGY JANUARY 2018 The Bellona Foundation is an international environmental NGO based in Norway. Founded in 1986 as a direct action protest group, Bellona has become a recognized technology and solution- oriented organizations with offices in Oslo, Brussels, Kiev, St. Petersburg and Murmansk. Altogether, some 60 engineers, ecologists, nuclear physicists, economists, lawyers, political scientists and journalists work at Bellona. Environmental change is an enormous challenge. It can only be solved if politicians and legislators develop clear policy frameworks and regulations for industry and consumers. Industry plays a role by developing and commercializing environmentally sound technology. Bellona strives to be a bridge builder between industry and policy makers, working closely with the former to help them respond to environmental challenges in their field, and proposing policy measures that promote new technologies with the least impact on the environment.
