1. NAME AND TITLE
LIE-PN: Pn Neutron Transport in Radial Geometry Cell with Source Problems Calculation.
2. CONTRIBUTOR
EIR
Wuerenlingen A.G Switzerland through the OECD Nuclear Energy Agency Data Bank,
Issy-les-Moulineaux, France.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 360 Series (C00816I036000).
4. NATURE OF PROBLEM SOLVED
LIE-PN solves source problems with time independent PN spherical harmonics neutron transport equations, multi-group r-geometry cell with annular zones, choice of boundary conditions, and of significance of eigenvalue.
5. METHOD OF SOLUTION
Lie series.
6. RESTRICTIONS OR LIMITATIONS
Value of N in PN, number of energy groups and number of zones are limited only by size of core storage, which is dynamically allocated.
7. TYPICAL RUNNING TIME
A 3 group P3 problem takes 31.4 seconds.
8. COMPUTER HARDWARE REQUIREMENTS
Upwards of 1000 common storage depending on problem. FORTRAN COOP monitor.
9. COMPUTER SOFTWARE REQUIREMENTS
Standard IBM OS MVT.
