FSXSEC is a collection of cross section libraries to be used for nuclear fuel cycle shielding calculations, generated from the pseudo-composition-independent VITAMIN-C cross section library:

1. A composition-dependent self-shielded fine-group library with 171 neutron groups and 36 gamma groups, and a broad-group library with 22 neutron and 21 gamma groups for AMPX.

1. A broad-group microscopic and a broad-group macroscopic library in ANISN format.

To generate library (a), AMPX modules BONAMI, CHOX, and MALOCS were used. To generate library (b), AMPX modules NITAWL and AXMIX were used.

AMPX modules BONAMI, CHOX, MALOCS NITAWL, and AXMIX were used to generate the cross section libraries.
