| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 32 |
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:
-
guidance for the selection of computational methods;
-
criteria for verification and validation of calculation methods used by reactor core analysts;
-
criteria for evaluation of accuracy and range of applicability of data and methods;
-
requirements for documentation of the preceding.
