Some reactor kinetics mathematical
modelling problems are considered in the framework of the standard 6-
group delayed neutron constants (Keepin, ABBN, JENDL, ENDF/B6) with
energy and isotope dependent precursor half-lives, and the new 8-group
delayed neutron data (Spriggs, Campbell, Piksaikin) with "universal"
precursor decay constant (or half-life) groups identical for all isotopes and
energies.
