  • Power excursion of the training and research reactor of Budapest University

    A three-dimensional neutronic code POWEX-K has been developed, and it has been coupled with the subchannel thermal-hydraulic core analysis code MI based on the momentum integral model. This forms the integrated neutronic/thermal hydraulics code system POWEX-K/MI for the accident analysis of the training and research reactor at the Budapest University of Technology and Economics (BME Reactor). An ...

  • Changing the energy game with the ‘power of one’

    Who among us has not eagerly described the smart meter to a non-energy person only to be greeted by a blank stare, or worse the retort: “Why would I want to track my electricity costs all day?” You try to explain the profound applications: smart appliances that talk to the power grid, consumer clubs that sell energy savings, your car serving as a power plant. But the conversation then ...

  • Thermal hydraulic analysis of small nuclear reactor core by using comparative approach of THEATRe and Relap5 code

    Thermal analysis of a nuclear reactor is very important in determining its design. It can produce desired thermal power without exceeding limitations on core components, which could lead to fuel failure and radioactive release into the environment. In this paper, thermal hydraulic studies of a small nuclear reactor core have been carried out by using two well–known thermal hydraulic codes, Relap5 ...

  • The influence of different hydraulics models in treatment of some physical processes in super-critical states of light water reactors accidents

    This work presents the development and testing of some thermal hydraulic models designed to address the limitations of using the Homogeneous Equilibrium Model (HEM) in predicting and simulating the hydraulic response of the positive reactivity-initiated power excursion accidents in small light water reactors. The neutronic response of such accidents has been investigated based on the neutron ...

  • Clean power in water supply systems as a sustainable solution: from planning to practical implementation

    Energy efficiency and renewable energy sources have drawn a greater attention by EU, in particular for climate change policies as it can substantially cut down CO2 emissions to meet EU environmental obligations. It is well established that in drinking pipe systems Pressure Reducing Valves (PRV) are used as a mean for excess energy dissipation for the purpose of pressure control. This type of ...

  • Hydro energy: techno-economic and social aspects within new climate regime

    Small hydro systems can provide electricity for: central-grid, isolated-grids, and/or remote power supplies. Small hydraulic power also provides an extra contribution to national electrical production in the case of consumption peaks. Although hydro is currently the second most used renewable energy source in the world, still there is a significant unexploited potential. The clean development ...

  • Validation of the STRIVE model for coupling ecological processes and surface water flow

    The 1D model package STRIVE is verified for simulating the interaction between ecological processes and surface water flow. The model is general and can be adapted and further developed according to the research question. The hydraulic module, based on the Saint-Venant equations, is the core part. The presence of macrophytes influences the water quality and the discharge due to the flow ...

  • Prediction of ungauged river basin for hydropower potential and flood risk mitigation: a case study at Gin River, Sri Lanka

    A hydrologic study was performed for ungauged river basin of Sri Lanka to examine synthetic discharge relations. Rainfall-runoff relationships were used for identifying hydrological conditions of the Gin River basin. The peak discharge achieves within 4.74 hours from the onset of the rainstorm and 11.95 hours take to reach its normal discharge conditions. Stream frequency of the Gin River is ...

  • Field Performance Testing for Pipeline Pumps

    Significant energy savings can be achieved by optimizing pump operating efficiency. Measuring the exact pump performance with crude oil under realistic conditions in the field is the first step towards improving the pump efficiency in the future. About 20 billion barrels of crude oil were transported through pipelines in 2015. Around the world, there are over one million kilometers of ...

  • Making ‘nanospinning’ practical

    Nanofibers have a dizzying range of possible applications, but they’ve been prohibitively expensive to make. MIT researchers hope to change that. Written by Larry Hardesty, MIT News Office. Nanofibers — strands of material only a couple hundred nanometers in diameter — have a huge range of possible applications: scaffolds for bioengineered organs, ultrafine air and water ...

  • Water Modelling over the Last 25 Years

    When reviewing the last 25 years of water modelling, there are two conclusions that are equally appealing. One is that all the building blocks for mathematical hydraulic modelling were in place 25 years ago except for computing, and so the recent history of all computer-based mathematical modelling is essentially the recent history of computing. The second view is that, in parallel with some ...
