Owing to the complexity of the real model, we made some simplifications to reduce the computational cost and optimise the calculation time. The absence of spacer grids, burnable poisons, and the simulation of only 1/8 of the fuel assembly, culminated in a simplified model, and at the same time, capable of representing the reactor's operating situation under normal conditions. We obtained the power density distribution in the fuel assembly through a neutronic-thermohydraulic coupling, using MCNP6 and ANSYS CFX-19, respectively. One of the main differentials of this model is the consideration of the temperature dependence of thermophysical properties, which shows a direct influence on the results. We assessed the correlations published in some reports about thermal conductivity, density, and specific heat to obtain expressions for these parameters. We determined the temperature profiles, the axial distribution of the coolant density, and the pressure drop in the fuel assembly to assess the thermohydraulic limits. The proposed model presented results according to the project limits for the normal operating conditions of the reactor. The implementation of a robust model provided consistent results, in addition to a methodology capable of carrying out more complex analyses.","PeriodicalId":35144,"journal":{"name":"International Journal of Nuclear Energy Science and Technology","volume":"14 1","pages":"97"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46345027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various methods could be employed in order to improve the heat transfer efficiency such as generating turbulent flow and injection of nanoparticles in the host fluid. In the current study, water/Al2O3 nanofluid forced swirl flow boiling has been investigated by using homogeneous thermophysical model within Eulerian-Eulerian framework through a twisted tape tube and boiling phenomenon was modelled using the Rensselear Polytechnic Institute approach. In addition to comparing the results with the experimental data and their reasonable agreement, it was evidenced that higher flow mixing results in more uniform bulk temperature and lower wall temperature along the twisted tape tube. The presence of Al2O3 nanoparticles in the boiling flow field showed that increasing the nanoparticle concentration leads to a reduced vapour volume fraction and wall temperature.","PeriodicalId":35144,"journal":{"name":"International Journal of Nuclear Energy Science and Technology","volume":"14 1","pages":"114"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47896001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
