  • Experimental investigation of flow-induced vibration in PFBR steam generator sector model

    The 500 MWe Prototype Fast Breeder Reactor (PFBR) is under construction at Kalpakkam. It is a liquid metal sodium-cooled pool-type fast reactor with all primary components located inside a sodium pool. Fission heat is transferred to a secondary sodium system in an intermediate heat exchanger, which is in turn transferred to water in a Steam Generator (SG). The PFBR-SG is a vertical shell and ...

  • Cogeneration steam power desalting plants using steam turbines

    This paper presents the reasons and merits of using cogeneration generation power desalting plants (CPDP), the different methods used to rate their performance, and their drawbacks. The ratings of the CPDP are crucial, because the fuel cost allocation between the water and power depends on the rating method used. The ratings are usually based on the first and the second laws of thermodynamics. A ...

  • Attention to the use of steam boilers in the industry

    In the industry, if people need to use high-temperature steam , then the steam boiler will be used; water can be heated to a quite high temperature, and generates high-temperature steam . Steam boilers and other hot water boiler are not the same , if people want to use the steam boiler, the boiler must be certified , or else once operated wrongly , then the consequences are very terrible.  ...

  • RELAP5-3D modelling of heat transfer components (intermediate heat exchanger and helical-coil steam generator) for NGNP application

    The Next Generation Nuclear Plant project is aimed at the research and development of a helium-cooled high-temperature gas reactor that could generate both electricity and process heat for the production of hydrogen. The heat from the high-temperature primary loop must be transferred via an intermediate heat exchanger to a secondary loop. Using RELAP5-3D, a model was developed for two of the heat ...

  • Reducing entropy generation by volumetric heat transfer in a supersonic two-phase steam flow in a Laval nozzle

    In a supersonic flow of pure vapour in adiabatic diffusers, under some circumstances, nucleation phenomenon occurs and consequently vapour condensation is observed. In this process, the resulted pressure rise is called the condensation shock, which causes the entropy generation. The innovation of this research is analytically modelling the volumetric heat addition to the steam flow in a 1D ...

  • Development of one-dimensional computer code DESOPT for thermal hydraulic design of sodium-heated once through steam generators

    Once-through Steam Generator (SG) is a critical component of Liquid Metal Fast Breeder Reactor (LMFBR) plant. It is a counter current heat exchanger, in which heat is transferred from the hot sodium flowing on the shell side to water/steam in tube side. High pressure subcooled water enters the SG tube from bottom, gets heated up to saturation, goes through nucleate boiling, dry out and post dry ...
