Machines used:

Package ID	Orig. computer	Test computer
NEA-1081/01	FACOM M-380

3. DESCRIPTION OF PROGRAM OR FUNCTION

SLAROM solves the neutron integral transport equations to determine flux distribution and spectra in a lattice and calculates cell averaged effective cross sections.

[ top ]

4. METHOD OF SOLUTION

Collision probability method for cell calculation and 1D diffusion for core calculation.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Variable dimensions are used throughout the program so that computer core requirements depend on a variety of program parameters.

[ top ]

6. TYPICAL RUNNING TIME

It varies with geometry option and number of spatial regions. An infinite plate geometry problem with 14 regions requires about 30 sec CPU on a FACOM M-380.

[ top ]

7. UNUSUAL FEATURES OF THE PROGRAM

PDS files are used to keep the macroscopic and microscopic cross sections, etc.

[ top ]

8. RELATED AND AUXILIARY PROGRAMS

Cross section library of JFS2 or JFS3 type which may be generated by the TISM-PGG code. The MIX code to compose macroscopic cross sections and the PDSDMP code to print out data saved in a PDS file.
