Licensing: Authorization for performing ac-
tivities connected with use of NPP and sources
of ionizing radiation.
Life Cycle: A set of stages in creation, imple-
mentation and use of a system (system component)
within a time period that starts from the moment
of concept development and determination of
technical requirements and ends in the moment
of removal of system (system component) from
operation due to impossibility or inexpediency of
further intended use.
NPP I&C Safety: A part of nuclear and ra-
diation safety, relating to jointly operating I&C
systems and manufacturing equipment of NPP
power units and depending on proper operation
of the I&C systems.
NPP Nuclear and Radiation Safety: A
feature of non-exceeding determined limits of
radiation effects on personnel, the population and
the environment under NPP normal operation,
operational events and design basis accidents
and also of restricting radiation effects in beyond
design basis accidents.
Safety Regulation: Regulation of safety
principles in order to ensure safety of people,
environment, nuclear facilities and sources of
ionizing radiation.

Safety: Assessment of documents, substantiat-
ing safety of NPP I&C systems, for compliance
with NPP safety principles and also the main
requirements of nuclear and radiation safety as-
surance, determined in legislative and regulatory
documents in force.
Knowledge Base: Computer system devoted
to acquisition, storage and representation of
knowledge in a specific subject area.
