Refractory high entropy alloys constituted of refractory alloying elements, such as W, Zr, Nb, Ti, Mo, Ta, and Hf, are of great interest due to their widespread use in areas such as the defense, aerospace, and nuclear power generation industries. Refractory high entropy alloys are one of the subgroups of high entropy alloys and are evaluated as great candidates for replacements of superalloys commonly used at high temperatures due to their good mechanical properties and corrosion and oxidation resistance at high temperatures. The motivation for performing this study is that there is currently no comprehensive analysis of the radiation shielding abilities of this new type of high entropy alloys. The purpose of the study was to evaluate the radiation attenuation parameters such as mass and linear attenuation coefficients, half value layer, mean free path, effective atomic number, and buildup factors of the refractory high entropy alloys, Al0.5Mo0.5NbTa0.5TiZr, Al0.25NbTaTiZr, HfMoScTaZr, Nb40Ti25Al15V10Ta5Hf3W2, NbCrMo0.5Ta0.5TiZr, Ti2VNbMoZr, and W23Mo23V17Cr8Ta7Fe22 by using EpiXS software. The mass attenuation coefficients of the alloys were also calculated by XCOM, a well-known code, to see the consistency of the obtained values. It was concluded that HfMoScTaZr and W23Mo23V17Cr8Ta7Fe22 have more shielding features, while Ti2VNbMoZr has the lowest shielding ability among the alloys.

In this study, calcium carbonate (CaCO3) was considered as nanoparticle. In the first part of the study, half-value layer (HVL) and mean free path (MFP) values, which are radiation shielding parameters, were investigated in determined energy ranges by Phy-X open access software. At increasing energy levels, the HVL value reached approximately 10 cm, while the MFP value reached approximately 17 cm. In the second part of the study, the reactor core geometry was modeled with the MCNP code and then the relative power distribution values were determined. COBRA code input was prepared with the determined relative power distribution values and thermal analyzes were made. These analyzes were performed for three different nanoparticle ratios. As a result of the analysis, the temperature value at the end of the channel was 613 K when only water was used as a coolant, while the temperature value at the end of the channel was 611.19 K when 0.03% nanoparticles were used. Although the coolant temperature increased with the nanoparticle ratio, it was observed that the temperature decreased when only water was used.

Gamma‐ray, fast neutron and charged particle shielding characteristics of Praseodymium (Pr3+) activated glasses with composition 10ZnF2‐(10‐x)SrO‐15Li2O‐65H3BO3‐xPr2O3(where x = 0.1, 0.5, 1.0, 1.5, and 2.0) are investigated. For this, the radiation shielding parameters are estimated by using Photon Shielding and Dosimetry (Phy‐X/PSD), Interaction of Proton, Alpha, Gamma rays, Electrons, and X‐rays with matter (PAGEX), Stopping Powers and Ranges for Electrons (ESTAR), and The Stopping and Range of Ions in Matter (SRIM) codes. Furthermore, the results are compared comprehensively and comparatively. The glasses with increasing Pr3+ content exhibited higher shielding potential. It can be said that the ZFLHBPr2.0 sample could be used as a shielding material in various applied fields. Additionally, the effect of Pr composition on structural transitions and time‐dependent volume‐collapse of this new family of borate glass doped with Pr is analyzed by molecular dynamics study (MD) based density functional tight binding method. The simulation results show that the addition of Pr led to the cubic‐orthorhombic transformation of simulation cell at determined temperature and 1 atm pressure. Also, a sudden decrease in volume are observed within a short time at 8% Pr composition (x = 2.0) atmospheric pressure. This result provides a strong connection between Pr composition and volume change with time and at constant low pressure.
