armi.nuclearDataIO.cccc.tests.test_dlayxs module
Tests for DELAYXS.
- class armi.nuclearDataIO.cccc.tests.test_dlayxs.DlayxsTests(methodName='runTest')[source]
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_ENDFVII1DecayConstants()[source]
Test ENDF/B VII.1 decay constants. Retrieved from ENDF/B VII.1.
- test_ENDFVII1NeutronsPerFission()[source]
Build delayed nu based on ENDF/B-VII data.
Notes
This data was simply retrieved from the NNDC [http://www.nndc.bnl.gov]. U-235 consists of 6 points for delayed nu and all others are only 4 points! Delayed group relative abundances are from G. Robert Keepin “Physics of Nuclear Kinetics” Table 4-7. There are comments there about why the fast fission data is standard.
