The Metal Subgroup of the NEA Working Group on Integrity and Ageing of Components and Structures (WGIAGE) will organise the Pipe Integrity Workshop to:

• Present the outcomes from the three piping int...

The NEA Working Group on Integrity and Ageing of Components and Structures (WGIAGE) discussed ongoing activities.

The objective of this “Kappa Workshop on Earthquake Ground Motions on Rock Sites” (held remotely from 25-28 May 2021), organised by the NEA Working Group on Integrity and Ageing of Components and Str...

This report presents the description and the interpretation of the tests carried out in the third phase of the NEA Working Group on Integrity and Ageing of Components and Structures (WGIAGE) activity...

The seismic design rules for nuclear power plant piping systems that have been in practice since the 1960s have been applied to hundreds of piping supports and seismic restraints for nuclear power pl...

Participants from 14 organisations, representing 11 countries, performed the benchmark exercise. Each participant provided a high-level summary of the leak-before-break (LBB) requirements in their co...

Forty nuclearexperts came together to explore the latest developments in preparations for the LTO beyond sixty years of existing nuclear power plants.  

The objective of this study is to compare leak rate computation practices and the applied tools and software solutions. Leak rate prediction is an important aspect of the leak-beforebreak assessment,...

In order to reach a better understanding of countries’ different approaches to the evaluation of vibrations detected in piping systems and components, the NEA Committee on the Safety of Nuclear Insta...

In the ASCET Phase III, the goal was to assess and develop the Phase II (blind benchmark) recommendations using additional test results. The Phase III simulations were performed using a full set of t...
