This is the first edition of CSA N286.7.1, Guideline for the application of N286.7-99, Quality assurance of analytical, scientific, and design computer programs for nuclear power plants.

Scope

1.1
This Guideline is intended to assist owner organizations and participants in the preparation and implementation of software quality assurance processes in compliance with CSA N286.7 and related requirements from CSA N286.

1.2
This Guideline is intended for those persons responsible for developing software governance and quality assurance programs and procedures.

(d) commercially available compilers, interpreters, and computer-operating systems; and
(e) commercially available mathematical libraries.
Note: Items (b) and (c) include "programmed applications", which are within the scope of CSA N286.7. A graded approach to quality activities and documentation similar to that specified for scripts in Clause 15 should be used.
