3. DESCRIPTION OF PROGRAM OR FUNCTION - CITATION is designed to solve problems using the finite difference representation of neutron diffusion theory, treating up to three space dimensions with arbitrary group to group scattering. X-y-z, theta-r-z, hexagonal z, and trigonal z geometries may be treated. Depletion problems may be solved and fuel managed for multi-cycle analysis. Extensive first order perturbation results may be obtained given microscopic data and nuclide concentrations. Statics problems may be solved and perturbation results obtained with microscopic data. This version of CITATION was released by ORNL as CITATION - Rev. 2, Supplement 3 in July 1972 and ran on mainframes. It was first ported to PC by AECL in October 1988. CITATION-PC included in the March 1996 package involved minor changes including the removal of overlay statements introduced in 1988. CITALDI-PC is a new modified version with list-directed input. The codes in this package accept cross sections in CITATION format. Macroscopic data may be entered according to format specifications in Section 008 of the published report. Microscopic data format is specified in Section 105. There are no codes in RSIC's code collection to generate data in CITATION format.

4. METHOD OF SOLUTION - Explicit, finite difference approximations in space and time have been implemented. The neutron-flux-eigenvalue problems are solved by direct iteration to determine the multiplication factor or the nuclide densities required for a critical system.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM -

6. TYPICAL RUNNING TIME - Run time is 15 to 45 minutes for the included test cases on a 486 DX running at 50 MHz.

7. UNUSUAL FEATURES OF THE PROGRAM - CITATION is considered unusual in that it should be relatively easy to modify the contents or to add routines. Effective techniques are incorporated to determine a critical system. More than one set of microscopic cross sections may be used in a system and nuclide behaviour can be followed on a sub zone scale within depletion regions. The user has flexible control over the route of a calculation as well as the edit of results.

8. RELATED AND AUXILIARY PROGRAMS - CITALDI-PC: List-directed input version.

CCC-0643/02:

CITAXSEC was added in Dec 1997 to process an ISOTXS binary cross section file to make an ASCII file which CITATION can use directly as part of the input data.

11. MACHINE REQUIREMENTS - CITATION 2.0 runs on personal computers equipped with an 80386 processor or better. At least 578K RAM must be available (use NORTON SI if possible to check). There cannot be any other resident programs (including PRINT). If you are using the shell command, make sure the e parameter does not exceed 800. This is necessary to allow the largest possible array size in the complied code. A numeric math coprocessor is required.

12. PROGRAMMING LANGUAGE(S) USED -
CCC-0643/02: FORTRAN-77

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED - The executables were created with the Lahey Fortran V5.1 and 5.2 compilers under DOS 6. They can be run in a DOS window of Windows95.
