Nuclear Third Party Liability (NTPL) treaties are international agreements which ensure that in the unlikely event of a nuclear incident there is a minimum amount of compensation available to victims and that claims are channelled appropriately to the operator of a nuclear installation and the jurisdiction in which an incident occurred.

The UK is party to the Paris Convention on Third Party Liability in the Field of Nuclear Energy (the Paris Convention) and the Brussels Convention Supplementary to the Paris Convention on Third Party Liability in the Field of Nuclear Energy (the Brussels Convention), together known as the Paris/Brussels Conventions, and the Convention on Supplementary Compensation for Nuclear Damage (CSC).

These treaties were initially established on the basis of traditional large-scale nuclear technologies, and this Call for Evidence seeks to gather evidence to support policy consideration on whether the default approach under the current system is the most appropriate for Small Modular Reactors (SMRs) and Advanced Modular Reactors (AMRs) or whether an alternative arrangement should be explored.

While this call for evidence is open to all, we are particularly keen to receive evidence from members of the nuclear and insurance industries.
