11 IEVT Eigenvalue type
= 0 The fixed source mode calculation in SRAC (IC2=3 and IQOPT=0) or
the external source problem with inhomogeneous source option in the
whole energy range (IC12=3 and IQOPT>0). IQOPT is specified below
in this Block.
= 1 k eff calculation
= 2 Time absorption α search
= 3 Nuclide concentration search (suppressed)
= 4 Zone thickness (delta) search (suppressed)
12 ISTART Input flux guess and starting option
= -5 Entire scalar flux guess from logical device 33
= 0 No flux guess required, but a fission guess (uniform in fissionable zone)
is automatically supplied
= 6 Problem restart dump is read from logical device 12
Other options in this item are suppressed.
13 MT Total number of cross-section blocks including anisotropic cross-sections. If
ISCT=0, this item is equal to number of materials used.
14 MTPS Number of input material set from the interface file ISOTXS supplied by SRAC.
As the next item MCR is set to zero, this item is identically equal to the number of
materials.
15 MCR Number of input materials from the code dependent input file,
= 0 (suppressed)
16 MS Number of mixture instructions
= 0 (suppressed)
17 IHT Row position of total cross-section in the cross-section format
= 0 (internally set)
18 HIS Row position of within-group scattering cross-section in the cross-section format
78
