armi.utils.reportPlotting module

Plotting Utils specific to reports.

This module makes heavy use of matplotlib. Beware that plots generated with matplotlib may not free their memory, even after the plot is closed, and excessive use of plotting functions may gobble up all of your machine’s memory.

Therefore, you should use these plotting tools judiciously. It is not advisable to, for instance, plot some sequence of objects in a loop at every time node. If you start to see your memory usage grow inexplicably, you should question any plots that you are generating.

armi.utils.reportPlotting.plotReactorPerformance(reactor, dbi, buGroups, extension=None, history=None)[source]

Generates a set of plots useful in reactor analysis given a populated reactor.

Parameters:

  • reactor (armi.reactor.reactors.Reactor) – The reactor to plot

  • dbi (armi.bookkeeping.db.DatabaseInterface) – The DatabaseInterface object from which to pull historical data

  • buGroups (list of float) – The burnup groups in the problem

  • extension (str, optional) – The file extention for saving plots

  • history (armi.bookkeeping.historyTracker.HistoryTrackerInterface object) – The history tracker interface

armi.utils.reportPlotting.valueVsTime(name, x, y, key, yaxis, title, ymin=None, extension=None)[source]

Plots a value vs. time with a standard graph format.

Parameters:

  • name (str) – Reactor.name

  • x (iterable) – The x-axis values (the abscissa)

  • y (iterable) – The y-axis values (the ordinate)

  • key (str) – A key word to add the item to the report interface

  • yaxis (str) – The y axis label

  • title (str) – the plot title

  • ymin (str, optional) – The minimum y-axis value. If any ordinates are less than this value, it will be ignored.

  • extension (str, optional) – The file extention for saving the figure

armi.utils.reportPlotting.keffVsTime(name, time, keff, keffUnc=None, ymin=None, extension=None)[source]

Plots core keff vs. time.

Parameters:

  • name (str) – reactor.name

  • time (list) – Time in years

  • keff (list) – Keff in years

  • keffUnc (list, optional) – Uncontrolled keff or None (will be plotted as secondary series)

  • ymin (float, optional) – Minimum y-axis value to target.

  • extension (str, optional) – The file extention for saving the figure

armi.utils.reportPlotting.buVsTime(name, scalars, extension=None)[source]

produces a burnup and DPA vs. time plot for this case.

Will add a second axis containing DPA if the scalar column maxDPA exists.

Parameters:

  • name (str) – reactor.name

  • scalars (dict) – Scalar values for this case

  • extension (str, optional) – The file extention for saving the figure

armi.utils.reportPlotting.xsHistoryVsTime(name, history, buGroups, extension=None)[source]

Plot cross section history vs. time.

Parameters:

  • name (str) – reactor.name

  • history (armi.bookkeeping.historyTracker.HistoryTrackerInterface object) – The history interface.

  • buGroups (list of float) – The burnup groups in the problem

  • extension (str, optional) – The file extention for saving the figure

armi.utils.reportPlotting.movesVsCycle(name, scalars, extension=None)[source]

make a bar chart showing the number of moves per cycle in the full core.

A move is defined as an assembly being picked up, moved, and put down. So if two assemblies are swapped, that is 2 moves. Note that it does not count temporary storage for such swaps. This is an approximation because in a chain of moves, only one out of the chain would have to be temporarily stored. So as the chains get longer, this approximation gets more accurate.

Parameters:

  • name (str) – reactor.name

  • extension (str, optional) – The file extention for saving the figure

FuelHandler.outage

sets the number of moves in each cycle

armi.utils.reportPlotting.plotCoreOverviewRadar(reactors, reactorNames=None)[source]

Plot key features of a set of reactors on radar/spider plots.

Useful for comparing reactors to one another.

armi.utils.reportPlotting.createPlotMetaData(title, xLabel, yLabel, xMajorTicks=None, yMajorTicks=None, legendLabels=None)[source]

Create plot metadata (title, labels, ticks).

Parameters:

  • title (str) – Plot title

  • xLabel (str) – x-axis label

  • yLabel (str) – y-axis label

  • xMajorTicks (list of float) – List of axial position at which to insert major ticks

  • yMajorTicks (list of float) – List of axial position at which to insert major ticks

  • legendsLabels (list of str) – Labels to used in the plot legend

Returns:

metadata – Dictionary with all plot metadata information

Return type:

dict

armi.utils.reportPlotting.plotAxialProfile(zVals, dataVals, fName, metadata, nPlot=1, yLog=False)[source]

Plot the axial profile of quantity zVals.

Parameters:

  • zVals (list of float) – Axial position of the quantity to be plotted

  • dataVals (list of float) – Axial quantity to be plotted

  • fName (str) – The file name for the plot image file.

  • metadata (bool) – Metadata (title, labels, legends, ticks)

  • nPlot (int) – Number of plots to be generated

  • yLog (bool) – Boolean flag indicating that y-axis is to be plotted on a log scale.
