JAEA-Data/Code 2007-004 - Welcome to Research Group for ...

data is identical with that of this input section. The CVMACT routine in SRAC converts the data
before calling CITATION by reading the data from PDS (MACRO or MACROWRK) file and writes
them into logical unit 31. For the latter, Card-008-1 is required and then Card-008-2 containing a
negative integer in columns 1-3 (KMAX0), input data after Card-008-3 are required. We shall describe this section to explain the
contents of the I/O unit 31.
Card-008-1 Input section name (I3)
Enter ’008’.
Card-008-2 Number of groups and scattering range (3I3)
1 KMAX Number of energy groups
< 0 Use the cross section provided by SRAC: Cross-sections are read from
logical unit 31. As KMAX is automatically supplied on logical unit 31,
absolute value of KMAX may be arbitrary.
> 0 User’s own cross-sections are read in this section, the KMAX value must
be proper.
2 IX28 Number of groups for down-scatter
As the code finds the correct value from the scattering vector, this value may be
different from the actual value.
3 IX29 Number of groups for up-scatter
As the code finds the correct value from the scattering vector, this value may be
different from the actual value.
