PSR-0013 SUPERTOG.

1. NAME OR DESIGNATION OF PROGRAM:  SUPERTOG.
Data generator - fine group constants and PN scattering matrices
from ENDF/B.

3. NATURE OF PHYSICAL PROBLEM SOLVED

SUPERTOG accepts nuclear data in  either a point by point or parametric representation as specified by ENDF/B. This data is averaged over each specified group width. The explicit assumption is made that the flux per unit lethargy is constant or that a suitable weight function will be supplied by the  user. When resonance data is available, resolved and unresolved resonance contributions are calculated and used as specified by input options. Fine group constants such as one-dimensional reaction arrays (absorption, fission, etc.), PN elastic scattering matrices,  and inelastic and (n,2n) scattering matrices are generated and placed on tapes in formats suitable for use by GAM-I, GAM-II, ANISN, or DOT.
SUPERTOG-2: Data are accepted in ENDF/B-2 format.
SUPERTOG-3: Data are accepted in ENDF/B-3 format.
SUPERTOG-4: data are accepted in ENDF/B-4 format.
SUPERTOG-JR is an extension of SUPERTOG to generate the energy deposition coefficients and atomic displacement constants due to the following nuclear reactions: elastic and inelastic scattering, (n,zn), (n,gamma), (n,p), and (n,alpha).

4. METHOD OF SOLUTION

The single-level Breit-Wigner formalism is used  for calculation of cross sections in the resolved resonance region.  Cross sections in the unresolved resonance region are computed by taking averages over suitable Porter-Thomas distributions of the neutron and fission widths. Smooth cross sections are calculated by  integration of point cross section data given in ENDF/B file 3. Elastic scattering matrices are computed from Legendre coefficients  of the scattering angular-distribution data. Inelastic scattering and (n,2n) matrices are computed from excitation functions for individual levels and by using a nuclear evaporation model above the region of resolved levels.
SUPERTOG-JR: For the numerical integration, the Gauss method is mainly used.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Since fixed, rather than flexible, dimensions are used, it is important to be aware of the maximum values allowed for certain key variables. Examples are - number of groups <=150, number of data points for each reaction type <=4000, and the number of Legendre coefficients <=30.
SUPERTOG-4: Number of data points for each reaction type <= 5000.
SUPERTOG-JR: Number of neutron energy groups <= 100.

6. TYPICAL RUNNING TIME

SUPERTOG-3:Running time varies greatly and is a function, primarily, of the number of groups, the number of resolved resonances, and the  length of the elastic scattering matrix. The average time required on IBM 360/91 to generate DLC-2D from ENDF/B-3 data was 2.2 minutes  per nuclide.
SUPERTOG-JR: For Fe with 39 energy groups, about 20 CPU minutes are  required on FACOM 230/75, of which 5.7 minutes are spent in the newly added routine.

8. RELATED AND AUXILIARY PROGRAMS

The DLC-2 retrieval program retrieves SUPERTOG output from a card image tape written in the ANISN card image format. This program will retrieve data from a maximum of 46 data sets and merge this data onto one data set. It will then, by input option, edit the data, punch cards in either the ANISN or DTF-IV format, or write an unformatted tape for use by ANISN. Another program is available which will merge up to a maximum of four card image tapes written in the GAM-II update format onto a  single tape. This program can also take the one-dimensional arrays from one tape and the two-dimensional arrays from another tape and merge this information onto a single tape. The single tape is input  to the SUPERTOG version of the GAM-II update program. The GAM-II update program has been modified to accept output from SUPERTOG on either punched cards or magnetic tape.
SUPERTOG-JR: Although the program is available as stand-alone code,  it has bee developed as part of the RADHEAT system.

11. MACHINE REQUIREMENTS

SUPERTOG-JR: 88K words of main storage and 13 system disks.

13. OPERATING SYSTEM OR MONITOR UNDER WHICH PROGRAM IS EXECUTED

The
coding is entirely in ASA standard FORTRAN (FORTRAN-IV), uses no programming tricks, and takes no advantage of any particular hardware or software.
SUPERTOG-JR: FACOM 230-75 with FORTRAN-H compiler.

14. ANY OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

SUPERTOG-III employs a rather elaborate overlay structure and extensive use of EQUIVALENCE statements to minimize core requirements.
