Steady-State Neutronics Methods for Power Reactor Analysis
This standard provides guidance for performing and validating the sequence of steady-state calculations leading to prediction—in all types of operating commercial nuclear reactors—of the following: (1) reaction rate spatial distributions; (2) reactivity; (3) change of nuclide compositions with time. (4) The standard provides the following: (1) guidance for the selection of computational methods; (2) criteria for verification and validation of calculation methods used by reactor core analysts; (3) criteria for evaluation of accuracy and range of applicability of data and methods; (4) requirements for documentation of the preceding. Note that the use of mixed uranium–plutonium oxide fuel is not within the scope of this standard
