BS ISO 18075:2018

This standard BS ISO 18075:2018 Steady-state neutronics methods for power-reactor analysis is classified in these ICS categories:

• 27.120.10 Reactor engineering

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:

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.
