Periodic Safety Review (PSR)

PSR.png

Objective

The objective of the Technical Safety Review of Periodic Safety Review (TSR-PSR) is to assist the Requesting Party in the process of establishing, implementing and undertaking regulatory supervision of the periodic safety review (PSR) programme to assure high level of safety of nuclear facilities throughout the  period of operation (typically next 10 years of operating lifetime or the end of the long term operation). The TSR-PSR is conducted to review the periodic safety review programme against the IAEA Safety Standards.

 

 

Scope of the review

The scope of the review is defined by the Requesting Party in consultation with the IAEA. The review could be focused on both PSR methodology documentation (PSR Bases Document) and results of the review of particular safety factors and global assessment.

 

The review is conducted against the present state-of-the-art in PSR methodology and good practices as documented in the IAEA Safety Standards. The framework for TSR-PSR review is typically based on the following IAEA requirements:

 

-        Safety Requirements on Safety Assessment for Facilities and Activities (IAEA Safety Standard Series No. GSR Part 4 (rev.1));

-        Safety Requirements Safety on Safety of Nuclear Power Plants: Design (Specific Safety Requirements No. SSR-2/1(Rev. 1));

-        Safety Requirements Safety on Safety of Nuclear Power Plants: Commissioning and Operation (Specific Safety Requirements No. SSR-2/2(Rev. 1));

-        Safety Requirements on Leadership and Management for Safety (IAEA Safety Standard Series No. GSR Part 2);

-        Safety Requirements on Emergency Preparedness and Response (IAEA Safety Standard Series No. GSR Part 7;

-        Site Evaluation for Nuclear Installations, IAEA Specific Safety Requirements No. SSR-1

 

Wide scope of IAEA Safety Guides is considered as supporting information for purposes of clarification of the requirements used as the basis for the review, particularly the Periodic Safety Review for Nuclear Power Plants Safety Guide (IAEA Specific Safety Guide No. SSG-25).

 

 

Benefits

The TSR-PSR offers interested Member States a number of benefits including:

-        Experts invited to carry out the mission are internationally respected and independent with no conflict of interest with the Requesting Party, which ensures respect for the findings and provides assurance that recommendations will be addressed by the Requesting Party. Thus, respected and independent review increases confidence of all stakeholders (including public), both local and international, that the nuclear installation meets all relevant international requirements and ensures the highest Safety Standards that can reasonably be achieved. In addition to these benefits, undertaking the TSR-PSR Service ensures that gaps in the coverage of safety requirements were identified and adequate attention was paid to available good practices.

-        Results of comprehensive PSR assessment provided by IAEA TSR-PSR Service provide reliable and valuable information for use in discussions and justification of the nuclear installation safety and its enhancements to regulators.

-        The process and results of TSR-PSR Service could be useful to Requesting Party to understand the latest interpretation of requirements and current best practices in meeting them and help entities responsible for PSR at the Requesting Party to avoid false interpretation of relevant PSR concepts and requirements.

-        The TSR-PSR Service can be undertaken with a PSR Bases Document and potential issues could be identified before the PSR thus avoiding resource losses and threat to deadlines.

Follow up missions can be requested to explore identified issues in more depth and provide assurance that actions taken to address the TSR-PSR Service results are adequate and quality of PSR is confirmed.
