In this regards elaboration of some comprehensive and legally binding instruments
of response to the said threat internationally seem to be possible only under conditions
of unprecedented consensus between diverse political forces acting in world stage
which is hardly possible in the currently existing situation of severe polarization of
the international community (unless some global incident similar to Stuxnet takes
place which will colorfully show the need in interaction of the countries concerned
in spite of diverse opinions on other issues of world order).
1.7.2 Basic Principles of Assurance Cybersecurity of Power
Facilities
Key target of safety assurance at all stages of life cycle of nuclear power plant’s
performance is taking appropriate efficient measures targeted at prevention of severe
accidents and protection of the stuff as well as local community at the account
of preventing under all circumstances emission of radioactive substances into the
environment.
Life cycle of a nuclear power plant, beginning from design phase and finishing
with final shutdown is closely linked with the activities targeted at safe assurance,
whereby each phase of activities features its own kit of tasks and challenges.
It should be noted here that by now at a global level the basic principles of safety
assurance at power plants. They are of generic nature fit to all types of reactors,
although they still need be adapted to either design or performance peculiarities of
some specific reactors. These principles are revised and complemented based upon
the results of operating nuclear plant experience and accident analysis. Basic safety
principles are set forth in the international regulatory documents. International atomic
energy agency (IaEA) and International nuclear safety advising group (INSAG) have
developed a set of advisory informative documents defining general approaches and
concepts of safety assurance. Among these documents, the one of crucial significance is “Basic principles of nuclear power plants” (INSAG-3) and “Safety culture”
(INSAG-4).
The basic principles of nuclear power plant safety assurance are defence-in-depth
(design) concept, fundamental safety functions, “no single point of failure” principle.
Defence-in-depth concept holds a special place among basic principles of nuclear
power plants safety assurance. This concept involves establishing a series of
sequential defense levels against potential failures of hardware and human errors,
including:
Establishing a series of physical barriers to prevent spreading of radioactive
contaminants into the environment;
Technical and administration activity to preserve the integrity and efficiency of
these barriers;
Activity to protect local community and environment in case of barriers destruction.
