Parcs Cross-Section format

  1. Background:
    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?

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