1. Peer Review Service on Safe Long Term Operation IAEA Activities in Safety of Long Term Operation
Robert Krivanek –
Project manager for LTO
Division of Nuclear Installation Safety

2. IAEA MANDATE Article III.A.6 of the IAEA statute:
“The Agency is authorized to establish or adopt … standards of safety for protection of health and minimization of danger to life” in connection with peaceful utilization of nuclear energy.
SSR-2/2 Safety of NPP: Commissioning and Operation
Requirement 14: Ageing management
The operating organization shall ensure that an effective ageing management programme is implemented to ensure that required safety functions of systems, structures and components are fulfilled over the entire operating lifetime of the plant.
Requirement 16: Programme for long term operation
Where applicable, the operating organization shall establish and implement a comprehensive programme for ensuring the long term safe operation of the plant beyond a time-frame established in the licence conditions, design limits, safety standards and/or regulations.

3. Challenges of safe long term operation
Unclear national energy strategy
Difficult to decide on investment for LTO
Lack of rules for LTO preparation
Routine operation of old units
Difficult to acquire young engineers
The best personnel attracted to operation of new modern plants
Post-Fukushima situation
Change of political and public acceptance
New safety requirements

4. How does the IAEA support safe LTO of NPPs?
Establishment of related IAEA Safety Standards
Fostering information exchange and establishing databases
IGALL Programme
AM and LTO workshops
SALTO methodology and experience transfer workshops
CRP – Coordinated Research Projects
Provision of peer review service (SALTO peer review) to assist Member States in application of related Safety Standards

5. Benefits of SALTO Review Service
Review of compliance with IAEA standards
Recommendations for improvement to reach the compliance
Opportunity for NPP staff to discuss their practices with experienced experts
Strengthening of public confidence to NPP
Support in licensing renewal procedure (or extension of operational permission procedure)

27. LTO modules of OSART missions
LTO module of OSART missions
Introduced in 2010 as an optional module
Based on SALTO methodology
Should not be the only review step to prepare for LTO
Conducted only by one expert
Can serve as a preliminary review of NPPs preparedness for LTO but is not sufficient as a comprehensive review of preparedness for LTO
SALTO workshop is recommended for better understanding of IAEA Safety Standards and expectations prior to LTO module
LTO module should be followed by a full SALTO mission (or Pre-SALTO mission) within months after LTO module 27
