Download and read online ebook Nuclear Reactor Multi-physics Simulations with Coupled MCNP5 and STAR-CCM+ write by Jeffrey N. Cardoni. This book was released on 2011. Nuclear Reactor Multi-physics Simulations with Coupled MCNP5 and STAR-CCM+ available in PDF, EPUB and Kindle. The MCNP5 Monte Carlo particle transport code has been coupled to the computational fluid dynamics code, STAR-CCM+, to provide a high fidelity multi-physics simulation tool for analyzing the steady state properties of a PWR core. The codes are executed separately and coupled externally through a Perl script. The Perl script automates the exchange of temperature, density, and volumetric heating information between the codes using ASCII text data files. Fortran90 and Java utility programs the assist job automation with data post-processing and file management. The MCNP5 utility code, MAKXSF, pre-generates temperature dependent cross section libraries for the thermal feedback calculations. The MCNP50́3STAR-CCM+ coupled simulation tool, dubbed MULTINUKE, is applied to two steady state, PWR models to demonstrate its usage and capabilities. The first demonstration model, a single fuel element surrounded by water, consists of 9,984 CFD cells and 7,489 neutronic cells. The second model is a 3 x 3 PWR lattice model, consisting of 89,856 CFD cells and 67,401 neutronic cells. Fission energy deposition (fission and prompt gamma heating) is tallied over all UO2 cells in the models using the F7:N tally in MCNP5. The demonstration calculations show reasonable results that agree with PWR values typically reported in literature. Temperature and fission reaction rate distributions are realistic and intuitive. Reactivity coefficients are also deemed reasonable in comparison to historically reported data. Mesh count is held to a minimum in both models to expedite computation time on a 2.8 GHz quad core machine with 1 GB RAM. The simulations on a quad core machine indicate that a massively parallelized implementation of MULTINUKE could be used to assess larger multi-million cell models with more complicated, time-dependent neutronic and thermal-hydraulic feedback effects.

This book was released on 2024-02-28. Multi-Physics and Multi-Scale Modeling and Simulation Methods for Nuclear Reactor Application available in PDF, EPUB and Kindle. A nuclear reactor operates in an environment where complex multi-physics and multi-scale phenomena exist, and it requires consideration of coupling among neutronics, thermal hydraulics, fuel performance, chemical dynamics, and coupling between the reactor core and first circuit. Safe, reliable, and economical operation can be achieved by leveraging high-fidelity numerical simulation, and proper considerations for coupling among different physics and required to provide powerful numerical simulation tools. In the past simplistic models for some of the physics phenomena are used, with the recent development of advanced numerical methods, software design, and high-performance computing power, the appeal of multi-physics and multi-scale modeling and simulation has been broadened.

Physics-based Multiscale Coupling for Full Core Nuclear Reactor Simulation available in PDF, EPUB and Kindle. Numerical simulation of nuclear reactors is a key technology in the quest for improvements in efficiency, safety, and reliability of both existing and future reactor designs. Historically, simulation of an entire reactor was accomplished by linking together multiple existing codes that each simulated a subset of the relevant multiphysics phenomena. Recent advances in the MOOSE (Multiphysics Object Oriented Simulation Environment) framework have enabled a new approach: multiple domain-specific applications, all built on the same software framework, are efficiently linked to create a cohesive application. This is accomplished with a flexible coupling capability that allows for a variety of different data exchanges to occur simultaneously on high performance parallel computational hardware. Examples based on the KAIST-3A benchmark core, as well as a simplified Westinghouse AP-1000 configuration, demonstrate the power of this new framework for tackling--in a coupled, multiscale manner--crucial reactor phenomena such as CRUD-induced power shift and fuel shuffle. 2014 The Authors.
