Input-Output Description
------------------------

A listing of CLAP-related input variables is given in :numref:`table-13.4-1` as an
aid in preparing or modifying SAS input decks. Additionally, the input
items on this list should be rechecked when problems are encountered in
the running of SAS cases with cladding motion. This list contains all
input items used directly by the following CLAP subroutines: TSCLD1,
TSCLD2, SODFRC and DENSIT and, in addition, input items used to initiate
CLAP and to calculate reactivity effects due to cladding motion (in
subroutine FEEDBK).

The CLAP output appears with both the main full printout and the boiling
printout. A sample output is shown in :numref:`figure-13.4-1`. The output labels
are generally self-explanatory. The Fortran variable and units
corresponding to each output item are given in :numref:`table-13.4-2`.
