62 Fundamentals of Magnetic Thermonuclear Reactor Design

These requirements and regulations are being developed at both the interna-
tional (IAEA Codes & Standards, IEC and ISO standards) and national levels.
The following documents are good examples of national-level regulations:
l The Rules and Regulations in Nuclear Power Engineering (known by its
Russian acronym PNAEg)—Russia.
l The DOE Regulations, ASTM, ASME, ANSI codes and standards—the
United States.
l The Rules and Regulations for Designing Nuclear Facility Components
(RCC)—France.
The Enterprise Quality Management System is a tool for design quality as-
surance. The IAEA standard 50-C/SG-Q (Quality Assurance for Safety of Nu-
clear Power Plants and Other Radiologically Hazardous Facilities) and manual
50-SG-Q10 (Quality Assurance under Designing) are mostly used to establish
quality requirements at a nuclear facility design stage. The requirements con-
tained in these documents can be grouped as follows:

1. Management requirements associated with design activities.
2. Requirements for the implementation of a quality assurance (QA) pro-
gramme at the design stage.
3. Requirements for the assessment of the QA programme implementation
during design stage.
4. The requirements of each group are detailed below.

Group one:
1.1 A QA programme, clearly and unambiguously defining all types of design
activities as well as the obligations and entitlements of officers involved in
those activities should be developed. It should also list the main suppliers
and contractors.
1.2 A responsible organisation should categorise the components and elements
of the facility under design in terms of their importance to the nuclear safe-
ty of the facility and specify a list of measures to be taken with respect to
each identified category.
1.3 Interfaces between the officers of the organisation and between suppliers
and contractors should be defined.
1.4 Ensure that the personnel of the responsible organisation, suppliers and
contractors have necessary skills and that these skills can be validated.
1.5 The schedule of design activities with indication of design stages, check
points and methods of their successful passing verification should be de-
veloped in the designing organisation before the implementation of design
and agreed with responsible persons inside the designing organisation and
in organisations’ suppliers and contractors.
1.6 Measures, which ensure that potential design non-conformances are ap-
propriately addressed, should be specified in advance.
