test_consistentAreaWithOverlappingComponents()

Test that negative gap areas correctly account for area overlapping upon thermal expansion.

Notes

This test calculates a reference coolant area by subtracting the areas of the intercoolant, duct, wire wrap, and pins from the total hex block area. The area of the pins is calculated using only the outer radius of the clad. This avoids the use of negative areas as implemented in Block.getVolumeFractions. Na-23 mass will not be conserved as when duct/clad expands sodium is evacuated

Bases: unittest.case.TestCase

Tests designed to verify mass conservation during thermal expansion

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_heightExpansionDifferences()

The point of this test is to determine if the number densities stay the same with two different heights of the same block. Since we want to expand a block from cold temperatures to hot using the fuel expansion coefficient (most important neutronicall), other components are not grown correctly. This means that on the block level, axial expansion will NOT conserve mass of non-fuel components. However, the excess mass is simply added to the top of the reactor in the plenum regions (or any non fueled region).

test_massFuelHeatup()

test_massCladHeatup()
