The Technical Safety Review (TSR) services address the needs of Member States at all stages of development and deployment of a nuclear power programme. This review is based on the IAEA Safety Standards, and provided at a Member State's request; it incorporates services dedicated to the following subject areas:
 
Review service conducted by the IAEA staff and international experts to review the safety of designs of nuclear power plants against IAEA Safety Standards. The review can be limited to specific technical areas.
Review service conducted by the IAEA staff and international experts to review the safety case of new reactor design against the requirements of IAEA Safety Standards on Safety Assessment for Facilities and Activities (GSR Part 4) and Safety of NPPs: Design (SSR-2/1).
Review service conducted by the IAEA staff and international experts to review the national safety requirements for the design or safety assessment of nuclear power plants against the IAEA Safety Standards. The review can be limited to specific requirements of interest.
Review conducted by the IAEA staff and international experts of Probabilistic Safety Assessments (PSAs) on the basis of Safety Guides SSG-3 and SSG-4 and TECDOC-832.
Review service conducted by the IAEA staff and international experts of accident management (AM) programme in Member States on the basis of Safety Standards GSR Part 4* and NS-G-2.15 and guideline SVS-9.
Service conducted by IAEA staff and international experts to review the PSR programme against the IAEA Safety Standards on Safety Assessment for Facilities and Activities (GSR Part 4) and the Safety Guide SSG-25 Periodic Safety Review of Nuclear Power Plants.

The TSR provides a tailored, independent evaluation of the plant design safety and safety assessment documentation and makes recommendations for enhancements and improvements to safety. The TSR services assist Member States in relation to the following topics:
• Safety of operating and new nuclear plant designs
• Specific sections of the safety analysis report
• Safety Requirements developed by regulatory authorities
• Safety assessments, also related to plant modifications
• Action taken to address emerging safety issues
• Countries' Periodic Safety Review programme 
The TSR addresses the spectrum of safety analyses performed in support of design, licensing and operation. The reviews address deterministic and probabilistic methods as well as risk informed decision making approaches.
 

Tailored to meet specific needs

The TSR services are conducted in support of Member States during the following life cycle stages: conceptual design, various pre-licensing as well as licensing phases, nuclear power plants construction and operation including periodic safety reviews and life time extension. Additionally, TSR can address specific technical or regulatory aspects, such as plans for plant modifications or safety regulation developed consistent with IAEA design safety and safety assessment requirements. The different subject areas can be combined to address specific Member State needs, including the review of the documentation of a complete safety case.
