rfr does not work with natural isotopes?

Postby keckler » Fri Sep 08, 2017 10:43 pm


I am trying to run a restart calculation using the binary restart file generated by the 'set rfw' option. When I run the calc, I get an error that says:
Code: Select all
Input error in parameter "mat" on line 0 in file "binaryRestart":

Nuclide 60000 not found in data libraries

For parameter description, try Serpent Wiki:


I am definitely not using a xs for natural Neodymium, so I assume the code is talking about natural Carbon, which I am using in my calculation. Probably the last zero in the ZAI is referring to the ground state?

Anyways, it seems that the 'set rfr' option might not know how to deal with natural isotopes. Is this true?

Yes, the last zero is the I in ZAI. Natural isotopes should not be used in burnup calculations because they cannot be depleted. This probably creates some confusion in the routine that reads the restart file.
