چکیده

The Xi’an Pulsed Reactor (XAPR) is characterized by its small core size and integrated fuel moderator structure, which results in a non-uniform power temperature distribution. Consequently, complex coupling relationship exists between neutronics thermal hydraulics, necessitating the assurance for operational safety of XAPR. To optimize experimental scheme reactor, refined three-dimensional steady-state nuclear-thermal analysis imperative. This study focuses on investigating calculation thermal-hydraulics model XAPR utilizing an open-source multi-physical framework known as Cardinal. neutron transport equation effectively solved using OpenMC, while heat conduction employed to compute elements. Furthermore, parallel multi-channel utilized determine fluid transfer. research centered XAPR, whereby Monte Carlo calculations under full-power conditions are conducted, specifically at capacity 2 MW. demonstrate strong agreement simulation outcomes. maximum recorded thermometric element 795.1 K, with deviation approximately −5.7% from measured value. Moreover, outlet channel observed be 360 exhibiting around −2.7%

Comparison of Three-Dimensional Double-Echo Steady-State Sequence with Routine Two-Dimensional Sequence in the Depiction of Knee Cartilage

Introduction: There are some routine two-dimensional sequences, including short tau inversion recovery (STIR), T2-weighted fast-spin echo (T2W-FSE), and proton-density fast spin-echo for diagnosing osteoarthritis and lesions of the knee cartilage. However, these sequences have some disadvantages, such as long scan time, inadequate spatial resolution, and suboptimal tis...

Reactor Simulation with Coupled Monte Carlo and Computational Fluid Dynamics

This paper demonstrates the applicability of Monte Carlo analysis to perform nuclear reactor core simulations with thermofluid feedback from a computational fluid dynamics code. An interface program, McSTAR, was written to couple MCNP5 to the commercial computational fluid dynamics code STAR-CD. McStar is a Perl script which alternately executes MCNP5, STAR-CD and cross section update routines ...
