1 Scope
This document provides guidance for performing and validating the sequence of steady-state calculations leading to prediction, in all types of operating UO2-fuel commercial nuclear reactors, of:
-
— reaction-rate spatial distributions;
-
— reactivity;
-
— change of nuclide compositions with time.
The document provides:
-
a) guidance for the selection of computational methods;
-
b) criteria for verification and validation of calculation methods used by reactor core analysts;
-
c) criteria for evaluation of accuracy and range of applicability of data and methods;
-
d) requirements for documentation of the preceding.
