Parcs Cross-Section format

  1. Jul 19, 2010 #1
    For a BWR-transient calculation I'm trying to convert cross-sections I got from PSG2/Serpent simulations in Parcs [CrossSection] Input files.

    My Question:
    Parcs makes use of
    SNF Nu-fission cross section​
    SKF Kappa-fission cross section​

    I assume this means Nu (as in neutrons/fission-event times fission cross section) but I'm not familiar with kappa in this context. Anyone have an idea what it denotes?

    Any and all documentation or insights about parcs cross-section input files would be more than welcome.

    There is a definition of kappa-fission in this thesis.

    Just search on kappa (see page 27/127 of the pdf, or page 17, eq. 4.2d), where kappa is related to the local power density.
