armi.reactor.blueprints.tests.test_materialModifications module

Tests for material modifications.

class armi.reactor.blueprints.tests.test_materialModifications.TestMaterialModifications(methodName='runTest')

Bases: TestCase

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

test_noMaterialModifications()

test_u235_wt_frac_modification()

Test constructing a component where the blueprints specify a material modification for one nuclide.

test_u235_wt_frac_byComponent_modification1()

Test constructing a component where the blueprints specify a material modification for one nuclide, for just one component.

test_u235_wt_frac_byComponent_modification2()

Test constructing a component where the blueprints specify a material modification for one nuclide, for multiple components.

test_materialModificationLength()

If the wrong number of material modifications are defined, there is an error.

test_invalidComponentModification()

test_zrWtFracModification()

test_bothU235ZrWtFracModification()

test_checkByComponentMaterialInput()

test_filterMaterialInput()

test_invalidMatModName()

This test shows proves that we can detect invalid material modification names when they are specified on an assembly blueprint. We happen to know that ZR_wt_frac is a valid modification for the UZr material class, so we use that in the first call to prove that things initially work fine.

test_matModsUpTheMRO()

Make sure that valid/invalid material modifications are searched up the MRO for a material class.

test_theoreticalDensity()

Test the theoretical density can be loaded from material modifications.
