Characterizing the voxel‐based approaches in radioembolization dosimetry with reDoseMC

Medical Physics, Volume 51, Issue 6, Page 4007-4027, June 2024.
Abstract Background Yttrium‐90 (90Y$^{90}{\rm {Y}}$) represents the primary radioisotope used in radioembolization procedures, while holmium‐166 (166Ho$^{166}{\rm {Ho}}$) is hypothesized to serve as a viable substitute for 90Y$^{90}{\rm {Y}}$ due to its comparable therapeutic potential and improved quantitative imaging.

Neutronic Analysis of Accident‐Tolerant Cladding Materials in 3D Full Core BEAVRS PWR Benchmark Using OpenMC Code

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
After the Fukushima Daiichi nuclear accident in 2011, the performance of nuclear fuel during accidents became a matter of great concern. To address this, a new type of fuel technology called accident‐tolerant fuel (ATF) has been developed with the goal of enhancing the ability of light water reactors (LWRs) to withstand severe accident conditions. Iron‐

Worst‐Case Accident Analysis of Accident Tolerant Fuel in NuScale Using RELAP5/MOD3‐Based Code

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
Research in nuclear engineering focusses on improving the safety of light water reactors (LWRs), driven by accidents like Fukushima in 2011. The severity of this accident was a result of active cooling system failures and cladding material oxidation resulting in hydrogen explosions.

Calculation of Detection Efficiency for the Gamma Detector using MCNPX

Acta Physica Polonica A, 2015
Radiation detection has been a main interest for researchers as all kind of produced particles in atomic and subatomic physics based on the measurement systems so-called detector. Detection efficiency is one of the main parameter in detection system besides many other different parameters of the detector.

MCNP/MCNPX model of the annular core research reactor. [PDF]

, 2006
Many experimenters at the Annular Core Research Reactor (ACRR) have a need to predict the neutron/gamma environment prior to testing. In some cases, the neutron/gamma environment is needed to understand the test results after the completion of an experiment.

A fast Monte Carlo code for proton transport in radiation therapy based on MCNPX

Journal of Medical Physics, 2014
An important requirement for proton therapy is a software for dose calculation. Monte Carlo is the most accurate method for dose calculation, but it is very slow. In this work, a method is developed to improve the speed of dose calculation. The method is
