Lessons Learned
• In the past: services had different / no specific
names e. g. for TSR-DS or TSR-PSA
• DSRS - Design Safety Review Services (1999 – 2010)
• IPERS - International Peer Review Service (1988-1999)
• IPSART - International PSA Review Team (2000-2015)
• TSR Services Guidelines streamlined, revised
and published
ONE document with 6 Appendices
Improved efficiency and effectiveness
11
Improvements since 2017
• TSR Services Guidelines streamlined,
revised and published
• IAEA Service Series 41
• Relevant information posted on GSAN and
available to the MS
• Side Event during TIC and virtual meeting
were conducted to collect feedback from
Requesting Parties as well experts involved
in the service
Recommendation from OIOS
• Review preparatory procedures when
conducting peer and safety review services to
ensure the applicability of these services to the
current and future nuclear power programmes of
the Member States
• Ensure the assignment of Sections to the peer
and safety reviews that have expertise related to
nuclear power programme development
Linkages to other Services
Conclusion
• Technical safety review services have been
conducted for over 30 years
• Evaluations and feedback have been collected
and implemented into update of service
guidelines
• TSR Service Guidelines: streamlined and
published
INCREASED EFFICIENCY
AND EFFECTVENESS

Technical Safety Review (TSR)
Service
SUBJECT AREAS
17
Annex
Design Safety (DS)
• DESCRIPTION
• The TSR-DS is conducted to review the safety of the specific design of an NPP
against the Safety Requirements on Safety of Nuclear Power Plants: Design (IAEA
Safety Standards Series No. SSR-2/1 (Rev. 1)), supported by the Safety Guides for
NPP design. This review can be limited to specific technical areas.
• OBJECTIVE
• The objective of the TSR-DS is to assist the Requesting Party to review the safety
documentation for NPPs and to make recommendations in order to enhance safety.
• DELIVERABLE • The deliverable is a report that summarizes the observations of the review and
includes, as appropriate, a set of recommendations to adhere to the IAEA safety
standards.
18
Generic Reactor Safety (GRS)
• DESCRIPTION
• The TSR-GRS is performed on the safety documentation submitted to the IAEA. It
provides an early evaluation of the safety documentation for a vendor ’s new NPP
design against the IAEA safety standards at the level of the Fundamental Safety
Principles (IAEA Safety Standards Series No. SF-1) and the Safety Requirements on
Safety Assessment for Facilities and Activities (IAEA Safety Standards Series No.
GSR Part 4 (Rev. 1)) and on Safety of Nuclear Power Plants: Design (IAEA Safety
Standards Series No. SSR-2/1 (Rev. 1)) .
• OBJECTIVE
• The objective of the TSR-GSR is to enable the Requesting Party to understand to
which extent the safety case is addressing the requirements of the IAEA safety
standards.
• DELIVERABLE
• The deliverable is a report summarizing the extent to which the safety case addresses
the IAEA requirements. It also includes, as appropriate, recommendations for
improving the adherence of the safety documentation to the IAEA safety standards.
19
Safety Requirements (SR)
• DESCRIPTION
• The TSR-SR is conducted to review the national safety requirements for NPPs against
the related IAEA safety standards at the level of the Fundamental Safety Principles
(IAEA Safety Standards Series No. SF-1), Safety Requirements on Safety of Nuclear
Power Plants: Design (IAEA Safety Standards Series No. SSR-2/1 (Rev. 1)), and the
Safety Requirements on Safety Assessment for Facilities and Activities (IAEA Safety
Standards Series No. GSR Part 4 (Rev. 1)). The review can be limited to specific
requirements of interest.
