Nuclear Engineering and Design

Contains input files (both complete input files as well as templates) along with some output files and CSV-formatted results, along with a few additional figures. Some of the results are not directly used in the corresponding publication, and are either indirectly used, or correspond to cases that were not included in the paper at all; usually those similar to the cases used in the paper, but with different parameters. The Polaris input files are incompatible with the distributed version of SCALE 6.2.

These files provide the raw data from steady-state and transient thermal hydraulic experiments performed as described in the manuscript titled "Single-Phase, Natural Circulation Annular Flow Measurements for Cartridge Loop Irradiation Experiments" submitted to the Nuclear Engineering and Design journal in August 2020.

This is a Python script containing all of the Pronghorn simulation results at the thermocouple locations. The data is stored in dictionaries, with various levels of "indentation" to contain all of the variations in closure model selection. This script plots the histograms included in the article.

Results calculated from the present model and the data used for comparison

Three dimensional transient analysis of the coupled RCS-containment integral system

Fault trees for 2 failure modes of MSRE freeze valve FV-103 and supporting basic event data

Raw data of Fig.4-Fig.6

This data contains the effective computation time of different algorithms for evaluating terms in orthogonal polynomials series. Algorithms for the Legendre and Zernike polynomial series were evaluated. The underlying algorithms are described in an submitted journal article that is currently under review. The "answer" value of the data set has no external use. Instead, it was an accumulated value that was used throughout the benchmarking process to prevent over-aggressive compiler optimizations from removing the loops used for benchmarking. Conveniently, it provided a way to debug and validate the algorithm variations by comparison with each other. The source files were updated from v1 to correct errors in Zernike polynomials for $Z_7^{\pm3}$. These were propagated from: V. Lakshminarayanan and A. Fleck. Zernike polynomials: a guide [http://dx.doi.org/10.1080/09500340.2011.633763] The value '2' should be replaced by '21'.

The reconstructed and prescribed positions for verification of Positron Emission Particle Tracking algorithm are compared to identify novel reconstruction errors experienced in multi PEPT measurements. The reconstructed tracer number 421 initially follows prescribed tracer 560. Later the reconstruction incorporates a position from the prescribed tracer number 559, switching to this tracer for the remainder of its trajectory.
