Welcome to ASAMPSA_E
The Fukushima nuclear accident in Japan resulted from the combination of two correlated extreme external events (earthquake and tsunami). The consequences, in particular flooding, went beyond what was considered in the initial NPP design.
Such situations can be identified using probabilistic safety assessment (PSA) methodology that complements the deterministic approach for beyond design accidents. If the results of a PSA conclude that such a low probability event can lead to extreme consequences, industry (system suppliers and utilities) or Safety Authorities may take appropriate decisions to reinforce the defence-in-depth of the plant.
The project ASAMPSA_E aims at promoting good practices for the identification of such situations with the help of PSAs and for the definition of appropriate criteria for decision-making in the European context. It offers a new framework to discuss, at a technical level, how “extended PSA” can be developed efficiently and be used to verify if the robustness of Nuclear Power Plants (NPPs) in their environment is sufficient.
The project gathers experts from 28 organisations in 18 European countries and is open for collaboration with organisations that have a broad experience in the field.
In all European countries PSA methodology is used to confirm and enhance the safety of NPPs in complement to the deterministic approach. The role and importance of PSA is defined and emphasised in many national and international safety standards.
Find out more on the European context of the project and on the needs for ASAMPSA_E, including what should be harmonised after the Fukushima accident.
The previous ASAMPSA2, project ended in December 2012. Activities allowed the development of European best practice guidelines for L2 PSA.
Visit the project’s website for more information and access the published guidelines.
20 July 2016 First versions of all guidance reports of ASAMPSA_E now available
The peer review of these reports is ongoing and results will be discussed during the coming ASAMPSA_E workshop from 12 to 14 September 2016.
20 May 2016 Announcement: ASAMPSA_E 2nd end-users workshop
The second ASAMPSA_E workshop on “Reviewing and discussing the ASAMPSA_E guidance reports for the development and use of extended PSA for NPPs” will be held from 12-14 September 2016. The workshop is hosted by the Vienna University and its preparation is coordinated by IRSN (France) and ICN (Romania).
This event is open to the organisations that have expertise in PSA developments and applications (or in hazards assessment) and that contribute to the ongoing survey/review of the reports produced by the ASAMPSA_E group.
24 October 2014 ASAMPSA_E present at EGU 2015
The EGU General Assembly 2015 will bring together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary and space sciences. The event will be held from 12 – 17 April 2015 in Vienna. The EGU aims to provide a forum where scientists can present their work and discuss their ideas with experts in all fields of geoscience.
The ASAMPSA_E project will co-convene two sessions during the event on:
- The implementation of external hazards in Probabilistic Safety Assessment for nuclear power plants
- Assessing extreme natural events for the safety of nuclear power plants
We invite the organisations that are involved with these topics to communicate on this.
23 October 2014 Presentation on the objectives and the progress of the ASAMPSA_E project now available
23 October 2014 Recommendations from first End-Users Workshop now available
A summary report of the recommendations resulting from the project’s first end users workshop organised in may is now available.
