GAPER1D; 1-dimensional transport perturbation theory. [UNIVAC1108; FORTRAN IV]

Technical Report ·
OSTI ID:6346735
Reactivity coefficients are computed using first-order transport perturbation theory for one-dimensional multi-region reactor assemblies. The number of spatial mesh-points and energy groups is arbitrary. An elementary synthesis scheme is employed for treatment of two- and three-dimensional problems. The contributions to the change in inverse multiplication factor, delta(1/k), from perturbations in the individual capture, net fission, total scattering, (n,2n), inelastic scattering, and leakage cross sections are computed. A multi-dimensional prompt neutron lifetime calculation is also available.UNIVAC1108; FORTRAN IV; EXEC8; One I/O device for reading input and printing results and one tape drive to read the code from tape. Core storage requirements are variable..
