These Regulations amend the Nuclear Installations Act 1965 (c. 57) (NIA 1965), as amended by Schedule 22 to the Energy Act 2023 (c. 52) (Schedule 22). Schedule 22 contains the amendments necessary to implement the Convention on Supplementary Compensation for Nuclear Damage (CSC) in the United Kingdom. The CSC is an international nuclear third party liability treaty that aims to establish a minimum national compensation amount amongst the CSC contracting parties and to further increase the amount of compensation to be made available through public funds by the CSC contracting parties, should the national amount be insufficient to compensate the damage caused by a nuclear incident.
