20.500.12556/DKUM-57950 MERITVE PRETOKOV V NEK FLOW CAPACITY MEASUREMENTS OF NPP KRŠKO Magistrsko delo obravnava v prvem delu opis nekaterih metod merjenja pretokov v Nuklearni elektrarni Krško. V glavnem delu sem opisal pretok napajalne vode v NEK, merjen z Venturijevo cevjo, ki tvori del celotnega sistema meritve od zajemanja do indikacije oziroma regulacije pretoka. Izvedena je bila tudi primerjalna meritev pretoka po cevi z zaslonko in z prenosnim ultrazvočnim merilnikom pretoka Na koncu naloge je podan predlog izboljšave trenutne meritve glavne napajalne vode z novejšo in sodobnejšo metodo. This thesis discusses the measurements of flow capacities in different flow circles in the nuclear power plant Krško. In the first part the measurement methods and techniques are described. The measuring system of the flow in the feedwater circle by Venturi meter is presented in detail, which is a significant part of overall measurements needed for apparatus regulation. The comparison between two measurements systems is highlighted. The thesis is concluding with proposal of the process to implement newer and modern method as additional and comparable to existing reference method. meritev pretoka metode merjenja pretoka ultrazvočni merilnik Venturijeva cev tlačni pretvornik sistem glavne napajalne vode kalibracija SMART-pretvornikov flow measurement flow measurement methods ultrasonic meter Venturi meter pressure transducer the main feedwater system SMART-calibration of transducers. true true false [M.
