Program-name Package-ID Status AND NEA-1235/01 Tested

Machines used: Package-ID Orig.Computer Test Computer NEA-1235/01 FACOM M-780 IBM 3083

3. DESCRIPTION OF PROGRAM OR FUNCTION - AND is designed to obtain reliable atomic number densities for neutronic calculation by the use of well established physical constants (Avogadro number, atomic mass, material density) and theoretical and experimental formulas.

4. METHOD OF SOLUTION - The theoretical formulas are employed to calculate number densities, except hydrogen number density in solutions where the formulas obtained by experiments are utilized.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - AND treats the fuel materials which are commonly seen at fuel fabrication plant and spent fuel reprocessing plant; namely U-H2O, UO2-H2O, UO3-H2O, ADU-H2O, UO2F2 aqueous, U3O8-H2O, UO2(NO3)2 aqueous, Pu-H2O, PuO2-H2O, Pu(NO3)4 aqueous, PuO2.UO2-H2O, and Pu(NO3)4-UO2(NO3)2 aqueous.

6. TYPICAL RUNNING TIME - Within five seconds.

NEA-1235/01:

NEA-DB executed the test case included in this package on an IBM 3083 computer in 0.15 seconds of CPU time.

7. UNUSUAL FEATURES OF THE PROGRAM -

8. RELATED AND AUXILIARY PROGRAMS - The output format of AND is designed to meet with the input format of MAIL (code to produce effective macroscopic cross sections). MAIL produces the cross section data to be fed directly to KENO-IV, and ANISN.
