*-----------------------------------------------------------------------
*
*Purpose:
* Compute and normalize the microscopic depletion reaction rates.
*
*Copyright:
* Copyright (C) 2002 Ecole Polytechnique de Montreal

*
*Author(s): A. Hebert
*
*Parameters: input
* IMPX print flag (equal to zero for no print).
* INR type of flux normalization:
* =0: out-of-core depletion;
* =1: constant flux depletion;
* =2: constant fuel power depletion;
* =3: constant assembly power depletion.
* IGLOB out-of-fuel power in flux normalization. Compute the burnup:
* =-1: using the Serpent mode 0 empirical formula in the fuel;
* =0: using the power released in the fuel;
* =1: using the power released in the global geometry.
* NGROUP number of energy groups.
* NBMIX number of mixtures.
* NBISO number of isotopes/materials including non-depleting ones.
* NCOMB number of depleting mixtures.
* ISONAM alias name of isotopes.
* IPISO pointer array towards microlib isotopes.
* DEN density of each isotope.
* FLUMIX average fluxes in mixtures.
* VX volumes of the depleting mixtures.
* MILVO mixture index corresponding to each depleting mixture.
* JM position in isotope list of each nuclide of the depletion
* chain. A negative value indicates a non-depleting isotope
* producing energy.
* NVAR number of depleting nuclides.
* NSUPS number of non-depleting isotopes producing energy.
* NREAC maximum number of depletion reactions.
* HREAC names of used depletion reactions:
* HREAC(1)='DECAY'; HREAC(2)='NFTOT';
* HREAC(3)='NG' ; HREAC(4)='N2N'; etc.
* IDR identifier for each depleting reaction.
* RER energy (Mev) per reaction. If RER(3,J)=0., the fission energy
* is including radiative capture energy. Neutrino energy is
* never included.
* RRD sum of radioactive decay constants in 10**-8/s.
* FIT flux normalization factor:
* n/cm**2/s if INR=1;
* MW/tonne of initial heavy elements if INR=2;
* W/cc of assembly volume if INR=3.
* AWR mass of the nuclides in unit of neutron mass.
* IZAE 6-digit nuclide identifiers.
* FUELDN fuel initial density and mass.
* NXSPER perturbation order for cross sections.
* DELTAT perturbation coefficients for cross sections.
* MIXPWR flags for mixtures to include in power normalization.
*
*Parameters: output
* PFACT form factor for out-of-fuel power production.
* SIG microscopic reaction rates for nuclide I in mixture IBM:
* SIG(I,1,IBM) fission reaction rate;
* SIG(I,2,IBM) (n,gamma) reaction rate;
* SIG(I,3,IBM) N2N reaction rate;
* ...;
* SIG(I,NREAC,IBM) neutron-induced energy released;
* SIG(I,NREAC+1,IBM) decay energy released (10**-8 MeV/s).
* VPHV integrated fluxes in mixtures.
