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.

• OBJECTIVE

• The objective of the TSR-SR is to assist the Requesting Party in the process of issuing

or revising national safety requirements for NPPs 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.

methodological aspects modelled in the probabilistic safety assessment, as well as

probabilistic safety assessment applications to enhance safety.

• DELIVERABLE

• The deliverable is a report that summarizes the observations of the review and

includes, if needed, a set of recommendations to improve the adherence of the

probabilistic safety assessment documentation to the IAEA safety standards.

21

the IAEA General Safety Requirements on Safety Assessment for Facilities and

Activities (IAEA Safety Standards Series No. GSR Part 4) and Specific Safety

Requirements on Safety of Nuclear Power Plants: Commissioning and Operation

(IAEA Safety Standards Series No. SSR-2/2 (Rev. 1)) supported by the Safety Guide

on Periodic Safety Review of Nuclear Power Plants (IAEA Safety Standards Series

No. SSG-25).
