6. Component Parameters
This document lists all of the Component Parameters that are
provided by the ARMI Framework. See armi.reactor.parameters for use.
Name |
Description |
Units |
|---|---|---|
volume |
Volume of this object. |
cm^3 |
area |
Cross sectional area of this component. |
cm^2 |
mult |
The multiplicity of this component, i.e. how many of them there are. |
|
mergeWith |
Label of other component to merge with |
|
type |
The name of this object as input on the blueprints |
|
temperatureInC |
Component temperature in °C |
°C |
numberDensities |
Number densities of each nuclide. |
#/(bn*cm) |
detailedNDens |
High-fidelity number density vector with up to thousands of nuclides. Used in high-fi depletion runs where low-fi depletion may also be occurring. This param keeps the hi-fi and low-fi depletion values from interfering. See core.p.detailedNucKeys for keys. |
atoms/(bn*cm) |
pinNDens |
Pin-wise number densities of each nuclide. |
atoms/(bn*cm) |
percentBu |
Burnup as a percentage of initial (heavy) metal atoms. |
%FIMA |
pinPercentBu |
Pin-wise burnup as a percentage of initial (heavy) metal atoms. |
%FIMA |
buRate |
Current rate of burnup accumulation. Useful for estimating times when burnup limits may be exceeded. |
%FIMA/days |
massHmBOL |
Mass of heavy metal at BOL |
g |
burnupMWdPerKg |
Burnup in MWd/Kg of heavy metal |
MWd/kg |
customIsotopicsName |
Label of isotopics applied to this component. |
|
modArea |
A (component, operation) tuple used to add/subtract area (in cm^2) from another components area. See c.getArea() |
|
zrFrac |
Original Zr frac of this, used for material properties. |
|
pinNum |
Pin number of this component in some mesh. Starts at 1. |
|
theoreticalDensityFrac |
Fractional value between zero and one, inclusive, for the theoretical density of the material stored on this component. |
|
molesHmBOL |
Total number of moles of heavy metal at BOL. |
mole |
puFrac |
Current average Pu fraction. Calculated as the ratio of Pu mass to total HM mass. |
