20.500.12556/RUL-160887 Prediction of recirculation flow rate for icing prevention in water intake supply systems of nuclear power plants During winter conditions, water intake structures represent one of many critical parts of hydraulic structures. Frazil ice deposits, accumulates and adhere to trash racks that can, in severe circumstances, completely prevent the water from entering the intake structure. One of the possible ways to cope with frazil ice blockage is by using waste heat of the discharge water, where a portion of the pumped water is recirculated back via a feedback loop to the intake structure. The recirculated water, serving as a heat source, can then somewhat warm the intake water and indirectly the air in the intake structure. In this work, an equation is derived that predicts the temperature of pumped water as a function of the recirculated-to-pumped water ratio and a case study on treating a water intake structure in a nuclear power plant is presented. The example demonstrates that, with a proper ratio between the pumped and recirculated flow rate, the formation of frazil ice and atmospheric icing could both be prevented. water intakes hydraulic structures cold weather conditions frost prevention vodno zajetje hidravlične konstrukcije preprečevanje zmrzali true false true Angleški jezik Slovenski jezik Članek v reviji 2024-09-05 09:15:32 2024-09-05 09:15:35 2025-08-08 13:33:30 0000-00-00 00:00:00 2019 0 0 Str. 63-70 Vol. 161 May 2019 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2021-03-07 621.22(045) 0165-232X 10.1016/j.coldregions.2019.02.013 16512283 Halilovic,_Urevc,_Koc_-_Prediction_of_recirculation_flow_rate_for_icing_prevention_in_water_intake_supply_systems_of_nuclear_power_plants.pdf Halilovic,_Urevc,_Koc_-_Prediction_of_recirculation_flow_rate_for_icing_prevention_in_water_intake_supply_systems_of_nuclear_power_plants.pdf 1 25A195A36C691C215A11B65BB5AF8519 14852ab42b40d6fdb7d61ce9b138b088b7ee7d2aaa89774f063557e3b3e2f2e7 03720777-6b58-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189695 https://www.sciencedirect.com/science/article/pii/S0165232X18303483?dgcid=author 1 a4004290-6b56-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189692 Fakulteta za strojništvo 0 0 0
