armi.reactor.blueprints.reactorBlueprint module

Definitions of top-level reactor arrangements like the Core (default), SFP, etc.

See documentation of blueprints in The Blueprints Input File for more context. See example in armi.reactor.blueprints.tests.test_reactorBlueprints.

This was built to replace the old system that loaded the core geometry from the cs[‘geometry’] setting. Until the geom file-based input is completely removed, this system will attempt to migrate the core layout from geom files. When geom files are used, explicitly specifying a core system will result in an error.

System Blueprints are a big step in the right direction to generalize user input, but was still mostly adapted from the old Core layout input. As such, they still only really support Core-like systems. Future work should generalize the concept of “system” to more varied scenarios.

class armi.reactor.blueprints.reactorBlueprint.SystemBlueprint(*args, **kwargs)

Bases: yamlize.objects.Object

The reactor-level structure input blueprint.

Note

We use string keys to link grids to objects that use them. This differs from how blocks/assembies are specified, which use YAML anchors. YAML anchors have proven to be problematic and difficult to work with

A Reactor Level Structure like a core or SFP.

Notes

yamlize does not call an __init__ method, instead it uses __new__ and setattr this is only needed for when you want to make this object from a non-YAML source.

construct(cs, bp, reactor, geom=None, loadAssems=True)

Build a core/IVS/EVST/whatever and fill it with children.

Parameters

• cs (Settings object.) – armi settings to apply

• bp (Reactor object.) – armi blueprints to apply

• reactor (Reactor object.) – reactor to fill

• geom (optional) –

• loadAssems (bool, optional) – whether to fill reactor with assemblies, as defined in blueprints, or not. Is False in UniformMeshGeometryConverter within the initNewReactor() class method.

Raises

• ValueError – input error, no grid design provided

• ValueError – for 1/3 core maps, assemblies are defined outside the expected 1/3 core region

attributes = <yamlize.attribute_collection.AttributeCollection object>

class armi.reactor.blueprints.reactorBlueprint.Systems(*args, **kwargs)

Bases: yamlize.maps.KeyedList

Initialize a Map.

Parameters

• *args – sequence of key/value pairs.

• **kwargs – kwargs for input to OrderedDict.

attributes = <yamlize.attribute_collection.KeyedListAttributeCollection object>

item_type

alias of armi.reactor.blueprints.reactorBlueprint.SystemBlueprint

armi.reactor.blueprints.reactorBlueprint.summarizeMaterialData(container)

Create a summary of the material objects and source data for a reactor container.

Parameters

container (Core object) – Any Core object with Blocks and Components defined.
