\section{Introduction}
|
||||
|
||||
\begin{frame}{Background}
|
||||
My background:
|
||||
\begin{itemize}
|
||||
\item<1-> B.S. Nuclear Engineering, RPI (2007)
|
||||
\item<1-> M.S. Nuclear Scince and Engineering, MIT (2009)
|
||||
\end{itemize}
|
||||
Origin of OpenMC:
|
||||
\begin{itemize}
|
||||
\item<1-> Working on advanced parallelization for Monte Carlo
|
||||
\item<1-> Needed testing platform - MC21?
|
||||
\item<1-> Ultimately decided to start from scratch
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}{Goals}
|
||||
Overall objectives of OpenMC:
|
||||
\begin{itemize}
|
||||
\item<1-> Fully featured, capable of realistic physics
|
||||
\item<1-> Written in a modern programming language (F2003)
|
||||
\item<1-> Easy to understand inner workings
|
||||
\item<1-> High performance
|
||||
\item<1-> Extensible for research purposes
|
||||
\item<1-> Open source and freely available
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}{Monte Carlo}
|
||||
Rather than solving the transport equation by discretizing the spatial,
|
||||
energy, and angular variables, Monte Carlo solves the transport equation by
|
||||
following individual particles as they move stochastically through a medium.
|
||||
\begin{itemize}
|
||||
\item<1-> Standard deviation $\propto \frac{1}{\sqrt{N}}$
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
% -----------------------------------------------------------------------------
|
||||
\section{Methods and Theory}
|
||||
|
||||
\begin{frame}{Solution Algorithm}
|
||||
\begin{itemize}
|
||||
\item<1-> Loop over particles
|
||||
\begin{enumerate}
|
||||
\item<1-> Sample particle from distribution
|
||||
\item<1-> Track particle to next collision
|
||||
\item<1-> Sample nuclide within material
|
||||
\item<1-> Sample reaction within nuclide
|
||||
\item<1-> Repeat from step 2 until particle dies
|
||||
\end{enumerate}
|
||||
\end{itemize}
|
||||
|
||||
While particle is being tracked, keep track of collision rate, fission rate,
|
||||
etc.
|
||||
\begin{equation*}
|
||||
\phi = \frac{1}{NV} \sum\limits_{\text{all collisions} \atop \text{in cell}} \frac{w_i}{\Sigma_t (E_i)}
|
||||
\end{equation*}
|
||||
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}{Geometry}
|
||||
\begin{itemize}
|
||||
\item<1-> All geometry is described as constructive solid geometry (unions and
|
||||
intersections of second-order surfaces)
|
||||
\item<1-> $Ax^2 + By^2 + Cz^2 + Dxy + Eyz + Fxz + Gx + Hy + Iz + J = 0$
|
||||
\item<1-> e.g. to construct an annulus
|
||||
\end{itemize}
|
||||
\include{annulus}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}{Cross-Sections}
|
||||
\begin{itemize}
|
||||
\item<1-> No need to reinvent the wheel
|
||||
\item<1-> ACE (A Compact ENDF) Format
|
||||
\begin{itemize}
|
||||
\item<1-> MCNP
|
||||
\item<1-> SERPENT
|
||||
\end{itemize}
|
||||
\item<1-> Three arrays: NXS, JXS, XSS
|
||||
\item<1-> Parse arrays into internal derived types
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}{Union Energy Grid}
|
||||
\begin{itemize}
|
||||
\item<1-> Each nuclide has cross-sections tabulated at different energy points
|
||||
\item<1-> To determine collision type, need to look up microscopic reaction
|
||||
cross sections
|
||||
\end{itemize}
|
||||
\include{union_energy_grid}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}{Tallies}{}
|
||||
{\bf Remember:} In Monte Carlo, the only answer you get is the one you ask
|
||||
for. In general, you don't get the global solution like you do in
|
||||
deterministic land.
|
||||
\begin{itemize}
|
||||
\item<1-> Implemented a robust tally system to calculate user-specified
|
||||
quantities of interest
|
||||
\item<1-> {\bf Filters:} Spatial location, incoming/outgoing energy, birth region, mesh
|
||||
\item<1-> {\bf Responses:} Flux, reaction rates, currents, etc.

||||

\begin{frame}{Compiling}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}{XML Input Format}
|
||||
Unlike many nuclear codes, OpenMC uses a modular XML input format
|
||||
\begin{itemize}
|
||||
\item<1-> Building a geometric model -- {\bf geometry.xml}
|
||||
\item<1-> Assigning materials to volumes -- {\bf materials.xml}
|
||||
\item<1-> Setting parameters for the simulation -- {\bf settings.xml}
|
||||
\item<1-> Determining which quantities to score -- {\bf tallies.xml}
|
||||
\end{itemize}

||||
