Parcs Cross-Section format

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.

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.
