This report examines the predisposal phase of radioactive waste management programmes in NEA member countries for all types of waste from high-level to intermediate- and low-level waste, and spent fu...

Several NEA Nuclear Science Committee (NSC) activities are concerned with the validation of computation methods and codes as applied to nuclear technology. One of the challenges has been and continue...

An evaluation of the occurrence of fluid flow through faults and fractures is of primary importance for the performance assessment of radioactive waste repositories located in argillaceous settings.

One of the initiatives of the Clay Club has been to launch a compilation and a review of the relevant literature on the basic concepts and mechanisms which control the movement of water, solute and g...

The Nuclear Law Committee (NLC) established the Working Party on Nuclear Liability and Transport (WPNLT) in 2016 to address the practical challenges related to the nuclear liability regime(s) applica...

The NEA Working Party on Nuclear Liability and Transport (WPNLT) met remotely on 17-18 December 2020.

The NEA Working Party on Nuclear Liability and Transport (WPNLT) held a virtual workshop on “The Qualification of Nuclear Substances and Nuclear Liability” on 29-30 March 2021.

To ensure reliable modelling of neutron physics within a state-of-the-art transient code, the neutron kinetics part of such a code should be based on the full-scale calculation of the space-time neu...
