  • A nuclear desalination complex with a VK-300 boiling type reactor facility

    RDIPE has developed a detailed design of an enhanced safety nuclear steam supply system (NSSS) with a VK-300 boiling water reactor for combined heat and power generation. The thermal power of the reactor is 750 MW. The maximum electrical power in the condensation mode is 250 MWe. The maximum heat generation capacity of 400 Gcal/h is reached at 150 MWe. This report describes, in brief, the basic ...

  • Reliability analysis of digital feedwater regulating valve controller system using a semi–Markov process model

    A semi–Markov process model is developed for the reliability analysis of Main Feedwater Valve (MFV) controller system that is used for regulating the water level in a steam generator. The proposed model is generalisation of a Markov process model reported in the literature and allows the use of non–exponential distribution for various state transition times.Keywords: digital instrumentation, ...

  • RELAP5–3D transient modelling for NGNP integrated plant

    The High–Temperature Gas–cooled Reactor (HTGR) is designed with outlet temperatures ranging between 750°C and 800°C. These high outlet temperatures enhance the power production efficiency and facilitate a variety of industrial applications. The objective of this study is to understand the response of the primary system to potential transients in the secondary system. For this analysis, the ...

  • Effect of substrate dilution on corrosion of colmonoy-6 weld overlays in nitric acid

    In the moderator system of some nuclear power plants, subsequent to the activation of the safety shutdown system, Gd3+ is removed by ion exchange prior to reactor start-up. During this process, the pH of the system water can get lowered to 3 due to generation of HNO3. Colmonoy-6, which is weld-deposited ...

  • Effective Removal of Zebra Mussels with Amiad Screen Technology

    Introduction The zebra mussel, native to the Black and Caspian Seas, has spread in the past few decades to waterways throughout the world mostly via ballast water. Zebra mussels, when non-indigenous to the environment, pose a serious threat to intakes of facilities that rely on fresh and brackish surface water. The mussel colonies obstruct the flow of water through the pipelines eventually ...

  • Continuous Quality Surveillance Scheme to minimize the Cost Of Poor Quality in the construction of hydroelectric powerplants - IDRA 2012

    During the construction of hydroelectric plants, poor quality can have a hugely negative impact on construction time, on plant performance and on safety. We propose a method of keeping under control the manufacturing of the most critical components, such as pressure parts, rotors and valves, with a view to minimizing the Cost of Poor Quality (COPQ). This method is known as the Continuous Quality ...

  • North Creek pumping station, King County, WA

    The new North Creek Pumping Station in King County, Wash., had to maintain the Department of Natural Resources' national reputation for outstanding reliability. To make sure it did, the design team applied the most advanced pump technology and vibration prevention methods. And the designers and utility put extra attention on meeting operations and maintenance needs. "We included folks from ...


  • KSB - H2O collaboration project: Reduce costs and improve quality of industrial wastewater treatment

    A Clearcat evaporator at KSB in La Roche Chalais (France) for the treatment of industrial wastewater on site. The KSB factory at La Roche Chalais (24), a subsidiary of Germany's KSB AG, manufactures AMRI brand butterfly valves. These valves are used in the construction, industrial, water, and electric power generation sectors. The production of these valves generates two main liquid wastes: ...
