SAFETY ANALYSIS
i  ncreasingly used in many countries, in a complementary manner
to the traditional deterministic design basis analyses and
defense-in-depth considerations
 art of the decision-making process in assessing the level
p
of safety of nuclear power plants and supporting various
risk-informed applications
 erformed in order to assess the risk of fuel damage
p
and radioactive releases from a range of internal initiators
and external hazards
r  egulatory bodies in many countries require PSA
to be performed for licensing purposes
 sed to support plant design and operation through the
u
applications such as:
plant risk profile and identification of design improvements
risk informed optimization of technical specifications
risk informed in-service inspection programs
configuration risk assessments to support implementation
of plant maintenance programs
risk informed categorization of systems, structures
and components to support quality assurance requirements
management of safety during shutdown
and other modes of operation
support to the development of severe
accident management guidelines
