Keywords:Subcritical Analysis, Cross section, KENO, MCNP, Cask

KENO code uses the cross section based on the regular rod pitch array even in the case that the rod pitch is irregular.
On the other hand, MCNP code can accurately model irregular rod pitch geometry as it is.
We compared calculation results between KENO and MCNP codes in cask model.
