*DECK TAVGCL
SUBROUTINE TAVGCL(IPMAP,IPPOW,NCH,NB,NCOMB,NX,NY,NZ,ARP,IMPX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Compute burnup limits over the fuel lattice for the time-average
* integration, based on the axial power shape over each channel.
*
*Copyright:
* Copyright (C) 2007 Ecole Polytechnique de Montreal
*
*Author(s):
* D. Sekki, R. Chambon
*
*Parameters: input/output
* IPMAP pointer to fuel-map information.
* IPPOW pointer to power 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.
* ARP relaxation parameter for shape convergence.
* IMPX printing index (=0 for no print).
*
*Parameters: scratch
* BURN0 low burnup integration limits.
* BURN1 upper burnup integration limits.
