1. P1. Overview of Objectives & Agenda of Technical Meeting
Presented by: Irina Kuzmina, Safety Officer, SAS/NSNI,
Technical Meeting on
Probabilistic Safety Assessment for New Nuclear Power Plants’ Design
IAEA, Vienna, Austria
October 1-5, 2012

2. IAEA SAFETY STANDARDS SERIES
IAEA has statutory obligation to develop international standards of safety
Safety Guides
Requirements
Safety Fundamentals
Article III.A.6 of Statute:
To establish or adopt standards of safety for the protection of health and minimization of danger to life and property
To provide for the application of these standards
IAEA SAFETY STANDARDS SERIES
Wide international consensus is achieved through a rigorous development process 2

3. SAFETY FUNDAMENTALS (1/2)
The fundamental safety objective is
to protect people and the environment from harmful effects of ionizing radiation
‘Safety’ means the protection of people and the environment against radiation risks
Ten safety principles have been formulated, on the basis of which safety requirements are developed and safety measures are to be implemented in order to achieve the fundamental safety objective

4. SAFETY FUNDAMENTALS (2/2)
Principle 5 ‘Optimization of protection’ states:
“To determine whether radiation risks are as low as reasonably achievable, all such risks, whether arising from normal operations or from abnormal or accident conditions, must be assessed (using a graded approach) a priori and periodically reassessed throughout the lifetime of facilities and activities.”

5. IAEA SAFETY GUIDES ON PSA (2010)

6. High-level use of PSA results:
GENERAL STATUS OF PSA
PSA performance:
Operating NPPs
Level 1 PSA - practically all currently operating NPPs
Level 2 PSA - performed or being pursued for many of them
Level 3 PSA is still not widely performed
PSA is usually performed by utility organizations
New NPPs
Level 1 PSA (and often Level 2 PSA)
Usually performed by designers and included in the safety case
High-level use of PSA results:
Comparison with risk targets or limits expressed in terms of specific values of risk metrics
In many countries, risk targets for new NPPs are more stringent, implying that the safety level of new NPPs should be higher

7. OBJECTIVES & SCOPE OF THE TM
The objective of this Technical Meeting (TM) is to serve as an international forum for presentations and discussions on the current practices pertaining to the development of PSA for new NPP designs
Specific focus on insights and special features related to methodological aspects of Level 1 and Level 2 PSA for new NPP designs
Reliability of passive safety systems, computer based I&C
HRA
Insufficient information
Consideration of the impact from internal and external hazards, etc.
National practices from the perspective of both designer/utility organizations and regulatory bodies

8. EXPECTED OUTCOME
The results of the meeting will be published as a technical report (Working Material) as soon as possible after the meeting
The report will serve as a basis for future IAEA activities relating to PSA for new NPP design
Summary of WG discussions, conclusions, recommendations for future activities, and papers will be included

9. Presentations by participants – first three days
WORKING PROCESS (1/2)
Presentations by participants – first three days
Panel discussion at the end of each day
Working group activities – one day (Thursday)
Two groups – Chairs will be elected – topics will be defined
Participants’ suggestions are welcome
