*DECK RESBRN
SUBROUTINE RESBRN(IPMAP,NCH,NB,NCOMB,NX,NY,NZ,LRSCH,IMPX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Initialize the axial shape and compute the first burnup limits per
* bundle for every channel (used for the time-average model).
*
*Copyright:
* Copyright (C) 2007 Ecole Polytechnique de Montreal
*
*Author(s):
* D. Sekki, I. Trancart
*
*Parameters: input
* IPMAP pointer to fuel-map information.
* NCH number of reactor channels.
* NB number of fuel bundles per channel.
* NCOMB number of combustion zones.
* NX number of elements along x-axis in fuel map.
* NY number of elements along y-axis in fuel map.
* NZ number of elements along z-axis in fuel map.
* LRSCH flag for the refuelling scheme of channels:
* =.true. it was read from the input file;
* =.false. otherwise.
* IMPX printing index (=0 for no print).
