The fretting wear at the grid assemblies in fuel assemblies as a result of flow-induced vibration (FIV) is one of the main causes of fuel failures in the Light Water Reactor (LWR). Therefore, accurately predicting FIV is crucial to mitigating this issue, and a computationally efficient simulation method is necessary. In this regard, the Unsteady Reynolds-Averaged Navier-Stokes (URANS) approach...
This study was part of a project that aims to investigate direct and scattered neutron flux, specifically, thermal and epithermal energy ranges around an unshielded PetTrace 880 cyclotron's target in several locations at a medical facility in the western region of Saudi Arabia. Efforts were made to characterize the neutron flux in a diagonal formation using a 3D-printed holder array within the...
The scintillation detectors are one of the best for gamma spectroscopy. Thus, this experiment aims to determine the resolution and Efficiency of the detection system composed of a SiPM board in addition to three types of scintillation crystals. Two of the crystals are inorganic, CaF2 and LYSO. The third one is organic plastic scintillator crystal, NE102A. 4 different sources are studied in...
This study investigates the impact of simulating different fuel shapes for a material testing reactor (MTR) using the OpenMC code. Two 2-dimensional bare fuel element models were constructed: one with a curved fuel element shape to represent the actual dimensions of the MTR, and another with a simplified flat fuel element shape with the same amount of fuel as the curved model. The neutron...
Due to their high specific heat, low viscosity, and good diffusivity, supercritical fluids have the potential to be ideal coolants. However, understanding the heat transfer for fluids under supercritical conditions has been a challenge. To understand the peculiar heat transfer characteristics, a wide range of experiments with different range of parameters and geometrical configurations has...
The accelerating growth of the population and the constant development of technology created a high energy demand. However, these involved factors increased energy consumption, therefore increasing the greenhouse effect and triggering the atmospheric pollutants., Thus creating demand for a more sustainable and cleaner source of energy, which emerged the role of nuclear energy. The nuclear...
Nuclear power became one of the major contributors to the worldwide energy mix, with a total share of 10% from thirty-three countries operating nuclear power reactors. Owing to the development of safe and advanced nuclear technologies, many countries are planning to embark on nuclear power. Moreover, it provides reliable and low-carbon power, which is well suited to address certain...
This senior project seeks to monitor Environmental Radioactivity (ERA) within Heqal village in Saudi Arabia, which has a high incidence of cancer. The research project will measure the radiation levels in the region's air, water, sand, stones, and plants. The study will utilize a Geiger counter and other radiation detection apparatus in the field work. The collected data will be analyzed to...
