Environmental Engineering Reference
In-Depth Information
definitions from different regulatory documents
in the knowledge base (full text of requirement
with a reference to a proper regulatory document,
form which this requirement was taken, is given).
Besides that, by analogy with the classification of
regulatory documents specified in Chapter 1 of
the knowledge base, requirements can also have
additional classification features that allow refer-
ring them to a certain stage of life cycle, safety
class, type of I&C systems or its components.
Due to use of this structure instead of sequen-
tial review of a large amount different regulatory
documents expert can quickly search of a separate
regulatory requirement and view how it is formu-
lated in different standards and guides.
Chapter 3 contains reports of state expert
review of NRS, published by SSTC NRS in
1995-2012, and also protocols of incorporation of
expert comments and other materials containing
results of safety assessment of the I&C systems
and their components. The knowledge base con-
tains names, registration numbers, dates of issue,
responsible expert review executor and full texts
of expert review reports of the NPP I&C systems.
Moreover, for each report additional classification
features, specifying an object (i.e. name of I&C
system, its modernized part, NPP and power unit,
on which I&C system is modernized or imple-
mented, enterprise-developer of I&C system or
its components) and an expert review object (i.e.
a certain document, substantiating safety) are
determined.
Chapter 4 contains data of modernized or new
I&C systems, implemented at NPPs of Ukraine.
The knowledge base includes name of modernized
(new) I&C systems, name of enterprise-developer
of I&C system, NPP and power unit, on which
the I&C system is implemented, its safety class,
year of implementation (modernization) and
short description of the system and the scope of
its modernization.
Chapter 5 contains documentation (in elec-
tronic and printed form) NPP and enterprises-
developers of modernized NPP I&C systems that
was submitted to SSTC NRS for expert review.
This information is included to the knowledge
base, because it is often used during expert activ-
ity for safety assessment of similar I&C systems
implementation at NPPs of Ukraine. Possibility
of comparative analysis of analogous systems not
only increases quality of expert review, but also
simplifies expert's work.
The knowledge base contains title and full
text of document and also information about
organization-developer of this document. Also for
each document additional features are determined.
They define to which exactly I&C systems this
document is related, for which NPP and power
unit was developed.
Moreover, in the knowledge base a connec-
tion between documents, substantiating safety
(contained in Chapter 5) and expert review reports
of these documents (contained in Chapter 3) is
established. Also a connection between docu-
ments (Chapter 5) and those NPP I&C systems
(Chapter 4) to which these documents are related
is organized.
Chapter 6 contains native and foreign safety
assessment methods. In the knowledge base
name of method, organization-developer of this
method, title of document, in which this method
is described and a full text with description of
method are specified.
The knowledge base contains the following
methods:
• Methods
of
logical
analysis
of
documentation;
• Methods of probabilistic safety analysis;
• Methods of design assessment of I&C sys-
tem reliability;
• Methods of static and dynamic analysis of
software of I&C systems.
